A fly rod casts the line, not the fly. That is why a rod, a reel and a line carry the same number and are bought as a set, and why the whole system is simpler than it looks on the shelf: pick the number, then put five parts together in order - backing to reel, line to backing, leader to line, tippet to leader, fly to tippet. This page does that once, with the makers' own words for each step, and the places where they differ printed rather than averaged. Where a statement is the site's own, it is labelled editorial.
Start here
Two pages on this site already touch this ground. Rods and reels explains the fly-weight system alongside spinning and casting gear, and line systems gives the beginner fly recipe: a 5-weight floating line, a 9-foot 4X nylon leader looped on, a spool of 5X tippet. Neither tells you what the number is made of or how the parts go together. This page does.
If you only want the order of assembly, skip to **Putting it together**. If you only want to know what to buy for a Kentucky creek, pond or the Cumberland tailwater, skip to **Kentucky, by rod weight**. Everything in between is what the number means and how the makers say to match it.
The number: what a line weight is
A fly line's weight is the weight of its first 30 feet, not counting the short level tip, measured in grains. The American Fly Fishing Trade Association (AFFTA) publishes the table, and a 5-weight is a line whose first 30 feet weigh 140 grains, give or take six. That is the number on the rod, the reel and the line box.
The standard is reproduced by Spinoza Rod Co., which credits AFFTA and gives the measurement rule in one parenthesis: "(Weight is for the first 30' of line minus level tip)". Murray's Fly Shop gives the same rule in prose and the history: the standard was set by the AFTMA, which the page says is no longer in existence, and was adopted by the AFFTA. Epic Fly Rods says why 30 feet: the length "represented the length of line" a single-handed rod "should be suitably loaded for reasonable casting", and adds that "lines for two handed rods use a different rating also published by the AFFTA." Scientific Anglers, in a staff reply on its taper page, puts the limit of the standard plainly: it "only dictates the weight of the first 30' of the line."
A grain is a small unit of weight, 437.5 to the ounce, so a 5-weight's first 30 feet weigh about a third of an ounce. The single-hand table, as Spinoza reproduces it, with the low, target and high figures in grains:
| Line weight | Low | Target | High |
|---|---|---|---|
| 1 | 54 | 60 | 66 |
| 2 | 74 | 80 | 86 |
| 3 | 94 | 100 | 106 |
| 4 | 114 | 120 | 126 |
| 5 | 134 | 140 | 146 |
| 6 | 152 | 160 | 168 |
| 7 | 177 | 185 | 193 |
| 8 | 202 | 210 | 218 |
| 9 | 230 | 240 | 250 |
| 10 | 270 | 280 | 290 |
| 11 | 318 | 330 | 342 |
| 12 | 368 | 380 | 392 |
| 13 | 435 | 450 | 465 |
| 14 | 485 | 500 | 515 |
| 15 | 535 | 550 | 565 |
Spinoza's reproduction also gives the figures in grams and notes a use for them: an unmarked line can be identified by putting its first 30 feet "on a precision scale." Everything a Kentucky angler fishes sits in the top half of the table's first ten rows; the rest is saltwater and two-hand work.
Two cautions attach to the table. First, the AFFTA pages themselves could not be opened in this run; both the address we were given and the PDF the search engines index returned "not found", so the figures here come from a maker's reproduction, the same one the rods and reels page cites. Status pending on the AFFTA URL. Second, whether the line in the box weighs what the table says for its number is a live disagreement. Lamson: "Some lines are a full or half-size heavy - that's normal and intentional." Epic says many lines run heavier than their stated weight, and sells its own as true to weight. Orvis's Tom Rosenbauer has a video on exactly this vocabulary, which its page describes as "true to line weight, half size heavy, one size heavy", with no transcript we could read. The fuller account of who says what is on rods and reels under the fly-weight section.

Matching line to rod to reel
Match the numbers. A 5-weight line on a 5-weight rod on a reel sized for a 5-weight line. Every maker in front of us says the same thing, and none of them hedges it.
Orvis's Jim Lepage and Marshall Cutchin: "A 5-weight rod is designed to cast a 5-weight line, and a 10-weight rod performs best with a 10-weight line." The reason: "The different line weights match the stiffness or load characteristics of the fly rod", and "Generally speaking, the heavier the fly line, the stiffer a rod has to be in order to cast it well." Scientific Anglers: "Assembling a balanced fly fishing rig is as easy as matching the numbers on the fly line to the numbers on the fly reel and fly rod", and "no matter which fly line you choose, it is essential to match the fly line weight with the rod weight." Its own example is the one this page is built around: "you would match an Ultra 4 5-weight fly line with a 5-weight fly rod, and you'd spool it on a 4/5/6 fly reel." Orvis's reel page gives the shopping order: decide the fishing, "From there you can determine a preferred line weight, and then the reel size which will fit that line weight", and "Match the fly reel to the rod weight noted on the handle."
What the number buys, in Scientific Anglers' words: "Lower numbers - weights 2-6 - denote smaller gear best suited to trout and panfish", and "As the numbers rise, so does the gear's ability to cast larger flies for bigger gamefish." The thing being sized is the fly, not the fish; Orvis's bass lesson says it directly in the Kentucky section below.
Taper. The line's number says how heavy its first 30 feet are; its taper says where the weight sits. Scientific Anglers: "The vast majority of lines in use today are Weight Forward designs", with most of the mass toward the front, while the double taper is "an older profile that is still in limited use today", suited to light-line, short-range dry-fly work and poor for distance and wind. Orvis's bass lesson wants "a simple weight forward taper". For everything on this page, a weight-forward floating line is the one to buy, and that reading is the site's, resting on those two statements (editorial).

When to overline, in the makers' words
You can fish a line one size heavier than the rod's number, and the makers say it works for short casts and loads the rod sooner; none of them recommends going lighter. How far you can go depends on the rod, and the only way to know is to try it.
Orvis's Tom Rosenbauer, in his short tip on the question: "you can overweight a rod by about one line size. Depending on the manufacturer." His page describes a heavier line bending the rod more, which can make short, gentle casts easier while longer casts become a struggle, and his verdict is modest: "Overlining by one size may work okay for you." Going the other way he advises against: "When you underline a fly rod, that fly rod isn't gonna flex enough", and the caster ends up forcing it. Lamson's rule is the same in one line: "You can over line (weight) a rod but it's typically best to avoid underlining." Scientific Anglers' staff, replying on its taper page, gives the two reasons to do it: a large or air-resistant fly, where you can "over line a small rod or use a larger rod with a standard line", and a new caster, for whom an overlined rod is "generally easier for a novice to cast" because the deeper bend opens up the casting arc and widens the timing margin. The same reply makes the point that undoes any fixed rule: "Fly rods, especially modern ones can handle a wide variety of weights, not just one", because the standard fixes only the first 30 feet and the reply says adding or removing about 5 feet of line changes the weight noticeably.
What that means for a Kentucky angler is the site's reading, labelled as such: a 5-weight rod carrying a 6-weight line is a legitimate close-quarters outfit for bluegill under overhanging willows, and the same rod with its own 5-weight line is the outfit for the long drifts the Cumberland asks for. The one thing every source rules out is the 4-weight line on the 5-weight rod (editorial, on Rosenbauer, Lamson and Scientific Anglers).
Basis: official (Orvis's Rosenbauer, Lamson, Scientific Anglers); the Kentucky application is editorial
Reel size and what the reel is for
Reels are sold by the line weights they fit, and the makers number them differently. Orvis uses Roman numerals, each covering three line weights; Lamson uses a plus sign; Scientific Anglers writes a range like 4/5/6. The reel holds the backing and the line, balances the rod, and for most Kentucky fish does little else.
Sizing. Orvis: "Orvis reels are sized using Roman numerals I, II, III, IV, and V, and coordinate with the following line weights:" size I for 1-3 weight line, II for 3-5, III for 5-7, IV for 7-9, V for 9-11. Its general rules: "all reel sizes boil down to the line weight they're designed to hold"; "a 4/5 reel means a reel suited to a 4- or 5-weight fly rod"; and "The numbers roughly correspond, so a 9-weight rod requires an 8- to 10-weight reel, depending on your preferences." Lamson: "A -5+ is built for 4-6 weight lines", "-5+ = Do it all Trout size", and if in doubt "it's usually better to have a larger reel than a smaller one." A 5-weight outfit therefore lands on an Orvis II or III, a Lamson -5+, or a 4/5/6, and the overlap in the Orvis scheme is real: a 5-weight line fits both the II and the III, with less backing in the smaller reel (editorial reading of the Battenkill capacity figures below).
Arbor. The arbor is the spool's core. Lamson: "Bigger arbor = faster pickup", "Tight coils from small arbors lead to tangles, snags, and frustration", and on the drag, "Small arbors shrink rapidly as line is pulled off, causing drag pressure to spike", while "Larger arbors maintain a more constant diameter, which keeps drag pressure more consistent throughout the fight." Orvis says large-arbor spools "hold the line in a position that's away from the center and the spindle", for "less reeling to retrieve your line, more backing and thicker lines". Orvis's Paul Fersen adds the cost: a large arbor "is much larger in diameter" and in his experience "didn't balance a light trout rod", with the mid-arbor as the compromise.
Drag. For bass, Orvis's lesson is blunt: "Your reel is mainly going to be used for storing your line", and "You don't need an expensive drag system for bass because they seldom pull any line." For trout, Fersen says the drag matters less than in salt water but a proper setting still protects the tippet, and his buying rule is "Buy a good quality reel and the drag system will be good, as well." Lamson describes the click-pawl alternative, where "Additional stopping power comes from palming the spool." How the drag is set is on rods and reels, where the published fractions are printed.
Balance. Lamson's test: "Balance the rod on your finger at the position that you would grip. Does the tip dive? Does the reel feel heavy?" Then: "If it feels good in hand and casts the way you like, that's what matters", and "For most trout fishing, lighter generally feels better." Fersen: "Never buy a reel without the rod in hand, and make sure you love the two together."

Backing: strength, amount and capacity
Backing is thin braided line wound onto the reel under the fly line. It fills the spool so the line sits on a bigger diameter, and it is what a fish runs into when it takes more than the fly line. For Kentucky freshwater the makers agree on 20 lb. How much to put on is answered two ways, as a recommendation and as a capacity, and the two numbers are not the same thing.
Strength. Orvis's backing is "braided Dacron", and its page says "20-lb. test is for trout, bass, and most freshwater fishing" while "30-lb. test is great for steelhead, salmon, bonefish, stripers, and more." Scientific Anglers' balanced-system page specifies 20 lb for trout, panfish and bass. Nothing we read calls for 30 lb on a Kentucky fish.
Amount. Scientific Anglers' recommendation is small: "Amount: 50 yd" of 20 lb for trout, panfish and bass, and 100 yd for pike, salmon and steelhead. Lamson's arithmetic shows what more buys: "90' fly line + 150 yards of backing = 540'." Lamson also says not to chase the number: "Capacity matters, but don't overthink it"; "Too much backing crowds the reel and can create pressure from your line rubbing on the reel"; and "Using 80-100yrds on a reel that can take 150yrds might not be a bad thing." The second reason to fill the spool has nothing to do with running fish: "Backing also increases working arbor diameter, improving line management and drag performance."
Capacity, as published. A reel's capacity is printed as a pair, a fly line plus a yardage of a given backing. The only capacity table we could read for a named reel is on a retailer's page (Bear's Den) for Orvis's Battenkill Disc. The retailer does not say where its table comes from, and Orvis's own product page was not reached, so whether these are Orvis's printed figures is Status pending; treat them as a retailer's listing:
| Battenkill Disc | Line weights | Backing capacity, as Bear's Den lists it |
|---|---|---|
| II | 3-5 | 20 lb: WF3 + 100 yd; WF4 + 75 yd; WF5 + 50 yd |
| III | 5-7 | 20 lb: WF5 + 125 yd; WF6 + 100 yd; WF7 + 75 yd |
| IV | 7-9 | 30 lb: WF7 + 225 yd; WF8 + 200 yd; WF9 + 175 yd |
Read against Scientific Anglers' 50-yard recommendation, the table says a 5-weight line on the smaller Orvis reel holds exactly the recommended amount and the larger one holds two and a half times it. Neither is wrong; the recommendation is a floor for freshwater and the capacity is a ceiling for the spool (editorial reading of the two sources). Fersen's general statement covers every maker: reels "are designed to hold a certain amount of backing with a certain size fly line."
Joining spools. Backing is sold in 100-yard spools among other sizes (Orvis lists 100, 200, 300, 400 and 3,000 yards). Scientific Anglers says that if you are winding by hand without a line winder, estimate the amount from a bulk spool or join 100-yard spools with a uni knot; the uni page covers that knot for line-to-line joins.

Putting it together, in order
Five connections, bottom to top. Each one below names the source that gives the step, and where this site has a knot page, it is linked. There is no arbor-knot page on this site yet, so that knot is given in full here from the makers' instructions.
1. Backing to the reel: the arbor knot
Orvis's knot page says the arbor knot "is used for tying the end of the backing to a fly reel", and gives three steps: "Tie an overhand knot in the backing and loop the backing around the arbor." "With the tag end, tie a second overhand knot around the standing part of the backing." "Pull the second knot tight against the arbor", then pull the standing part so the knotted tag end slides up snug against the first knot. Scientific Anglers' spooling page names the same knot, then adds one habit: "Put a half hitch of the backing around the spool to keep it from slipping when you start winding." Animated Knots describes the same structure as a noose with a stopper, calls the second overhand knot "essential" because it snugs the first against the arbor, and gives two warnings worth keeping: "If you make a Slip Knot by mistake it will just pull undone", and on a highly polished arbor some anglers wind the loop two or three times around it before the first half hitch, for friction. No source we read publishes a strength for this knot, and none needs to; it holds the backing to the spool and is never asked to hold a fish on its own (the last clause is editorial).
Wind the backing on under light tension. Scientific Anglers: lay it level by moving it side to side as you go. If you have a spare spool, Scientific Anglers gives the trick for filling the reel exactly: reverse the order, wind the fly line on first, add backing until the spool is full, then attach the backing to the empty spool and wind everything across onto it so the backing ends up underneath.
2. Backing to the fly line
Modern fly lines mostly end in a welded loop; line systems carries the source that calls it the industry standard. With a loop on the back of the line, Scientific Anglers' instruction is to tie a loop in the backing with a triple surgeon's knot, "making it large enough for the fly line spool to pass through", and join the two loop-to-loop. The large loop is what lets you change a fly line without cutting anything: the line's spool passes through the backing loop. The double surgeon's page covers the surgeon's knot family; Scientific Anglers asks for three turns here rather than two. For heavy lines or hard use it names a Bimini twist loop instead, which this site does not cover.
Without a loop on the line, Scientific Anglers says to attach the backing with a nail knot of 5 to 7 turns, and for gel-spun backing an Albright knot with 6 to 8 wraps. Neither of those is a page on this site; the nail knot steps Orvis publishes are summarised in step 4, because Orvis gives them for the leader end.
3. The fly line onto the reel
Wind it on evenly (Scientific Anglers). The pages we read give no winding direction and do not cover switching a reel between left- and right-hand retrieve; that is in the reel's own instructions, and we do not add a rule the makers did not (editorial note, not a sourced step).
4. Leader to the fly line
With a welded loop on the front of the line: Scientific Anglers says to tie a perfection loop in the leader butt and connect loop-to-loop. That page gives Orvis's three moves and the check: the finished join should look like a square knot, not a girth hitch. Some packet leaders come with the loop already tied; the loop-to-loop page says it found that only in retailer listings and does not rely on it.
Without a loop on the line, Scientific Anglers' instruction is to nail-knot a short butt section of monofilament, which "can vary from .021" to .025" in diameter depending on the weight of the fly line being used", matched to the leader's butt, and tie a perfection loop on its free end, so the line carries a permanent loop from then on. Orvis's nail-knot page calls it "the cleanest way to permanently attach a leader to a fly line" and specifies 5 wraps around the line and a tube, the tag end passed back through the tube, the tube withdrawn, the coils snugged by alternating pulls on the tag and standing ends, then a hard pull on the fly line and the standing leader to seat it before trimming. Orvis's page is for the leader; Scientific Anglers' 5-to-7-turn version is for backing. Same knot, two makers, two ends of the line.
5. Tippet to the leader, and the fly
The leader's fine end is replaced as you change flies. Fresh tippet goes on with a double surgeon's; the leaders and tippet page carries Orvis's method for rebuilding a leader that way, with the X table. The fly goes on with an improved clinch for trout flies or a non-slip loop for streamers and bass bugs; the line systems recipes name which.
Basis: official (Orvis knot pages, Scientific Anglers spooling page, Animated Knots); editorial notes labelled in the text
Leader and tippet, the short version
A 9-foot leader tapering to 4X or 5X covers most trout work; a shorter, heavier one turns over bass bugs. The complete table, the X-to-diameter rule and the length-by-situation list are on leaders and tippet; this section only says enough to finish the outfit.
Orvis's leader article names 7.5, 9 and 12 feet as the three common knotless lengths and says "9 feet is the most versatile and manageable length for trout fishing", recommending a 9-foot leader with a 4X or 5X tip as the setup that handles most dry, wet and nymph fishing. Its tippet chart gives the diameters and breaking strengths in its own nylon: 0X is .011 in and 15.5 lb, 2X .009 in and 11.5 lb, 3X .008 in and 8.5 lb, 4X .007 in and 6 lb, 5X .006 in and 4.75 lb, 6X .005 in and 3.5 lb, 7X .004 in and 2.5 lb, with the rule "Divide the hook size by 3 and you'll get the appropriate tippet size." Scientific Anglers' balanced-system page spans the same range by strength: "7X-0X (2 lb - 10 lb)" for trout and panfish, "8 lb - 12 lb" for bass.
Basis: official (Orvis, Scientific Anglers)
Kentucky, by rod weight
The recommendations below are three different answers for three different flies, not three opinions about one rod. The maker that says so is Orvis, in its bass lesson: "It's not really determined by the size of the fish." "It's more the size of fly to your fishing."
Bluegill and the other sunfish: 3- to 6-weight. Scientific Anglers puts panfish with trout: line, reel and rod all 4/5/6, rod 8 to 9 feet, weight-forward or double-taper line, 20 lb backing, 50 yards, leader 7X to 0X. The line systems panfish row on this site runs a step lighter, 3- to 5-weight with a 7.5-foot 4X nylon leader; the 3-weight is the site's own range, and no maker page we read in this run names a weight for bluegill specifically. Orvis's first-rod page has no panfish line at all. What the state says fly anglers throw is on the bluegill page: sponge spiders and small cork poppers along Herrington Lake's rocky bluffs. A cork popper is an air-resistant fly, and Scientific Anglers' staff reply above says that is the case for the heavier line or the heavier rod; a 5- or 6-weight is the comfortable top of the panfish band for poppers, a 3- or 4-weight the pleasure end for wet flies and spiders (editorial, on Scientific Anglers' two statements).
Largemouth bass: 8-weight. Orvis: "The best all-around rod for bass fishing for largemouth and smallmouth is probably an eight weight", because "you need a heavier line to drive some of those bigger flies": "Largemouths, bigger, more air-resistant flies." Scientific Anglers' bass band is 7/8/9 throughout, with a weight-forward line, an 8.5- to 9.5-foot rod, 20 lb backing, 50 yards, and an 8 to 12 lb leader. The reel, Orvis says, is "mainly going to be used for storing your line." The leader build and the bugs are on the largemouth bass page.
Smallmouth bass: 6- or 7-weight, with an argument for 8. Orvis: for smallmouth only, "you can use a six or even a seven weight, because the flies are a little bit smaller." "Smallmouths, smaller, slimmer flies, in general." The smallmouth bass page publishes the 8-weight case alongside and leaves the choice there, and the streamer fishing page carries the 6- or 7-weight streamer outfit. On a creek like Elkhorn or the upper Salt a smallmouth rod doubles as the heavy panfish rod, which is the one sentence of overlap this page offers (editorial).
Cumberland tailwater trout: 4- to 6-weight, and a 5 sits in the middle. The state's own column is the primary source here. KDFWR's Lee McClellan, writing on 26 December 2023 about fly fishing the Cumberland below Wolf Creek Dam, quotes John Hast's outfit: "Hast fishes a 4-weight fly rod for nymphs and a beefier 6-weight rod for throwing Woolly Buggers." For nymphs, "He uses a 12-foot tapered leader in 5X (about 5-pound test) for fishing nymphs" and "He ties about 3 feet of tippet line material to the end of the tapered leader." For the Buggers, "Hast uses a 4-foot section of what is known as a polyleader attached to his fly line" and "runs an 18- to 24-inch section of 4X (about 6-pound test) fluorocarbon tippet off the polyleader", because "A polyleader adds heft to the presentation and allows an angler to get a fly down in the water". The flies are "Copper Johns, Prince Nymphs and Hare's Ears in sizes 16 to 18." That is one angler's two-rod setup on one river, as the rainbow trout page already notes. The makers' trout bands bracket it: Scientific Anglers 4/5/6, Lepage and Cutchin "a 5-weight is a good choice to start with", Orvis's first-rod page "a 5WT or 6WT rod." A single 5-weight sits between Hast's two rods and inside every maker's band; it is the one-rod answer for the Cumberland, with the 12-foot 5X leader for the nymph rig and a polyleader for the Buggers swapped on loop-to-loop (editorial, on the sources named). The 12-foot leader is the tailwater length the leaders and tippet table gives, and a 4-foot polyleader with 4X is inside the streamer row there.
The Cumberland carries a trout permit for everyone, a protected slot and a generation schedule that decides whether you can wade at all; those are on the rainbow trout page with the regulation text and its dates, and on the Cumberland River tailwater water page. McClellan's column puts the generation rule first: "One must know the electrical generation schedule from Wolf Creek Dam before fishing the Cumberland River." Check the current rules with the Kentucky Department of Fish and Wildlife Resources before you go: KDFWR Fishing and Boating Guide.
One rod for all of it? The makers' bands overlap at 6: Scientific Anglers' trout and panfish band tops out there, Orvis's first-rod page starts bass there, and Hast's Bugger rod is a 6. A 9-foot 6-weight with a weight-forward floating line, an Orvis size III or equivalent reel, 20 lb backing, a 9-foot 4X leader for the trout and the bluegill and a 7.5-foot 0X to 2X leader for the bass reaches every fish on this page except the largemouth hair bug, where Orvis's 8-weight stands. Orvis's own beginner pick is in the same place: "try the most common first fly-rod size: a graphite 9', 6WT rod." That one-rod reading is editorial; the sources it rests on are named in each sentence.

What we don't know yet
- The AFFTA pages themselves. The specification address we were given and the PDF that search engines index both returned "not found" in this run. The table is read from Spinoza Rod Co.'s reproduction, with Murray's Fly Shop and Epic Fly Rods confirming the measurement rule in prose but not the figures (Murray's chart is an image). Status pending on a first-party AFFTA source.
- Orvis's reel capacities at first hand. The Battenkill Disc table was read on a retailer's page that does not say where its figures come from; Orvis's own product page did not come up in this run. Status pending.
- A maker's statement on half-size-heavy lines in its own words. RIO's product pages redirected or returned "not found"; Orvis's Rosenbauer video has no transcript. Lamson's one sentence is the only maker statement here. Status pending.
- A maker's rod weight for bluegill specifically. Scientific Anglers groups panfish with trout at 4/5/6; the site's 3-weight floor comes from its own line-systems page. Status pending.
- Winding direction and retrieve hand. None of the pages read covers it. Follow the reel's instructions.
- The strength of the arbor knot and of the backing-to-line loop. No source we read publishes either. The loop-to-loop page records the same gap for the leader join. Status pending.
- The two-hand AFFTA standard. Epic says it exists; we did not read it, and nothing on this page depends on it.
