The Fishing Gear Numbers
Fishing tackle is covered in numbers that don't mean what they look like they mean: a rod's power and action are two separate specs, a reel's gear ratio isn't the same as its retrieve speed, line test ratings aren't comparable across mono, fluoro, and braid, and hook sizes run in two opposite directions. This page is the normalized decoder table for all of it — a reference dataset, not a buying guide. Every row cites its source; pair it with the specific product's own spec sheet before you buy.
The one thing to know: Rod power describes stiffness (what lure/line weight loads the blank), and rod action describes where it bends — they are two independent specs, not one sliding scale, and most anglers only ever check one of them.
Rod power classes
| Power | Lure weight | Line weight | Typical use | Source |
|---|---|---|---|---|
| Ultralight (UL) | 1/64 – 1/16 oz | 1 – 4 lb mono | Panfish, trout, finesse presentations | Manufacturer rod spec charts (St. Croix, Ugly Stik, Daiwa published power/lure/line tables) |
| Light (L) | 1/32 – 1/8 oz | 4 – 8 lb mono | Panfish, small trout/bass, light jigs | Manufacturer rod spec charts (St. Croix, Ugly Stik, Daiwa published power/lure/line tables) |
| Medium-Light (ML) | 1/8 – 1/4 oz | 4 – 10 lb mono | Finesse bass, walleye, light crankbaits | Manufacturer rod spec charts (St. Croix, Ugly Stik, Daiwa published power/lure/line tables) |
| Medium (M) | 1/8 – 3/8 oz | 4 – 12 lb mono (or 8–14 lb rated on some blanks) | General bass/walleye, spinnerbaits, worming | Manufacturer rod spec charts (St. Croix, Ugly Stik, Daiwa published power/lure/line tables) |
| Medium-Heavy (MH) | 3/16 – 1 oz | 8 – 17 lb mono | Heavier jigs, Texas-rigs, moderate cover fishing | Manufacturer rod spec charts (St. Croix, Ugly Stik, Daiwa published power/lure/line tables) |
| Heavy (H) | 1/2 – 2 oz | 15 – 30 lb mono | Flipping/pitching heavy cover, big swimbaits, catfish | Manufacturer rod spec charts (St. Croix, Ugly Stik, Daiwa published power/lure/line tables) |
| Extra-Heavy (XH) | 1.5 oz and up | 25 lb mono and up | Musky, offshore bottom fishing, heavy structure work | Manufacturer rod spec charts (St. Croix, Ugly Stik, Daiwa published power/lure/line tables) |
Rod action — where the rod bends
| Action | Where it bends | Typical use | Source |
|---|---|---|---|
| Slow (full/parabolic) | Bends through the lower half to the butt | Treble-hook crankbaits, some glass panfish rods — the deep bend cushions hooksets so trebles don't tear out | Rod-building industry action convention (Rod Building Forum / manufacturer action diagrams) |
| Moderate / Moderate-Fast | Bends through the top half to roughly the midpoint | Crankbaits, topwaters, moderate cover — a compromise between hookset power and forgiveness on treble hooks | Rod-building industry action convention (Rod Building Forum / manufacturer action diagrams) |
| Fast | Bends mainly in the top third/quarter of the blank | Jigs, worms, single-hook baits, finesse bites — fast tip transmits bite feel and drives a hard, direct hookset | Rod-building industry action convention (Rod Building Forum / manufacturer action diagrams) |
| Extra-Fast | Bends almost entirely in the last few inches of the tip | Single-hook power techniques (flipping, punching) needing maximum sensitivity and hookset speed | Rod-building industry action convention (Rod Building Forum / manufacturer action diagrams) |
Rod length tradeoffs
| Length | Casting distance | Accuracy | Boat/kayak fit | Source |
|---|---|---|---|---|
| Under 6' | Shortest casting distance | Highest accuracy — best for tight roll-casts under docks/overhangs | Best in a kayak or small boat with low overhead clearance | Manufacturer length-tradeoff guidance (rod maker buying-guide copy, cross-checked across brands) |
| 6'6" – 7' | Balanced, the most common length sold | Balanced — the default for most techniques | Works in boats and most kayaks; the safe first-rod length | Manufacturer length-tradeoff guidance (rod maker buying-guide copy, cross-checked across brands) |
| 7'6" – 8' | Longer casts, more leverage on the hookset and fight | Lower accuracy for tight-quarters pitching | Needs more overhead/side clearance — better suited to open water and larger boats | Manufacturer length-tradeoff guidance (rod maker buying-guide copy, cross-checked across brands) |
| 8'+ (surf/musky/noodle) | Maximum casting distance and leverage | Lowest accuracy in tight spaces; unwieldy in a kayak cockpit | Purpose-built for surf/pier/musky, awkward in confined boats or kayaks | Manufacturer length-tradeoff guidance (rod maker buying-guide copy, cross-checked across brands) |
Line types compared
| Type | Stretch | Visibility | Abrasion resistance | Knot strength | Diameter-per-test | Source |
|---|---|---|---|---|---|---|
| Monofilament | ~15–25% stretch — most forgiving on hooksets and shock | Moderate — refracts light, more visible underwater than fluoro | Moderate abrasion resistance, degrades with UV exposure over time | Easiest to knot and holds knots reliably at moderate strength | Rated (test) diameter is the closest of the three to its actual breaking strength | Berkley / Sufix published monofilament spec sheets |
| Fluorocarbon | ~10–15% stretch — stiffer, less forgiving, more direct bite feel | Lowest — refractive index close to water, nearly invisible underwater | Best abrasion resistance of the three, holds up well on rock/structure | Requires more knot wraps and lubrication; brittle if cinched dry | Thicker per pound of test than braid, but closer to true-rated strength than braid | Seaguar / P-Line published fluorocarbon spec sheets |
| Braid | Near-zero stretch — maximum direct hookset and bite transmission | High visibility above water (opaque, often colored) — usually fished with a leader in clear water | Poor abrasion resistance against rock, but very high straight-line tensile strength | Needs braid-specific knots (uni, palomar) and doesn't cinch/knot like mono | Diameter-per-pound-test is the smallest of the three — a major reason braid's printed test is not directly comparable to mono/fluoro | PowerPro / Sufix published braid spec sheets (diameter-to-test tables) |
Line test (lb) vs. actual breaking strength — the honest version
| Claim | Reality | Source |
|---|---|---|
| Monofilament's printed test (e.g. "10 lb") | Generally the closest of the three line types to a true, lab-verified breaking point at that diameter | Berkley / Sufix published monofilament spec sheets |
| Fluorocarbon's printed test | Close to true breaking strength but at a thicker diameter than braid or mono rated to the same number, because fluorocarbon is a denser, stiffer material | Seaguar / P-Line published fluorocarbon spec sheets |
| Braid's printed test (e.g. "20 lb" braid at mono-diameter-4) | Frequently rated well above what an equivalent-diameter monofilament would break at — braid's tensile strength-per-diameter is simply higher, so its "test" number is not an apples-to-apples comparison to mono/fluoro test numbers | PowerPro / Sufix published braid diameter-to-test conversion tables |
| "Test" in general | A manufacturer's rated breaking strength under controlled lab conditions (dry line, straight pull) — knots, abrasion, UV wear, and wet vs dry line all reduce real-world strength below the printed number | Line manufacturer spec-sheet fine print (Berkley, Seaguar, PowerPro) |
Reel gear ratios, decoded
| Gear ratio range | Typical IPT (inches per turn) | Best for | Source |
|---|---|---|---|
| Slow (5.0:1 – 5.5:1) | ~20–24 inches per turn (typical spinning sizes) | Maximum cranking torque — deep-diving crankbaits, big swimbaits, slow-rolled spinnerbaits | Manufacturer reel spec sheets (Shimano, Daiwa published gear-ratio/IPT tables); Wired2Fish gear-ratio guidance |
| Medium (5.6:1 – 6.5:1) | ~24–28 inches per turn (typical spinning sizes) | All-purpose retrieve speed — jigs, worms, general bottom-contact techniques | Manufacturer reel spec sheets (Shimano, Daiwa published gear-ratio/IPT tables); Wired2Fish gear-ratio guidance |
| Fast (6.6:1 – 7.5:1) | ~28–32 inches per turn (typical spinning sizes) | Faster general retrieve, topwaters, covering water quickly between bites | Manufacturer reel spec sheets (Shimano, Daiwa published gear-ratio/IPT tables); Wired2Fish gear-ratio guidance |
| Extra-Fast (7.6:1 and up) | ~32–38+ inches per turn (typical spinning/baitcast sizes) | Reaction baits (spinnerbaits, chatterbaits), fast hook-set-and-retrieve techniques, flipping slack out fast | Manufacturer reel spec sheets (Shimano, Daiwa published gear-ratio/IPT tables); Wired2Fish gear-ratio guidance |
Gear ratio is turns-per-crank, not retrieve speed by itself — A reel's gear ratio (e.g. 6.2:1) is turns-per-crank, not speed by itself — actual retrieve speed (inches per turn, IPT) also depends on spool diameter, so two 7.0:1 reels from different lines can retrieve different amounts of line per crank. Always check the manufacturer's published IPT figure alongside the ratio when comparing reels.
Spinning reel sizes → line capacity & target species class
| Reel size | Typical line capacity | Target species class | Source |
|---|---|---|---|
| 1000 – 2000 | ~110–140 yd of 4–8 lb mono (or thinner braid equivalent) | Panfish, small trout, light finesse bass work | Shimano / Daiwa published reel line-capacity spec sheets |
| 2500 – 3000 | ~140–200 yd of 6–12 lb mono | General bass, walleye, inshore light-tackle species | Shimano / Daiwa published reel line-capacity spec sheets |
| 4000 | ~200–250 yd of 10–17 lb mono | Larger bass/pike, medium inshore saltwater, surf panfishing | Shimano / Daiwa published reel line-capacity spec sheets |
| 5000 and up | ~250+ yd of 15–30 lb mono, or much more in braid | Big inshore/nearshore saltwater, catfish, musky-adjacent big-bait work | Shimano / Daiwa published reel line-capacity spec sheets |
Drag system ratings
| Rating | What it means | Practical rule | Source |
|---|---|---|---|
| Manufacturer max drag (lb) | The maximum stopping force the drag washers can apply at full tightening, measured under lab conditions | Usable fishing drag is conventionally set well below max — roughly 25–33% of line test — to leave a safety margin against knots, nicks, and sudden surges | Manufacturer reel spec sheets (Shimano, Daiwa, Penn published max-drag ratings); general angling drag-setting convention |
Hook size numbering — the confusing inverse system
| Scale | Direction | Typical use | Source |
|---|---|---|---|
| Numbered scale: #32 (smallest) down to #1 (largest on this scale) | Gets SMALLER as the number gets LARGER | Panfish, trout, small freshwater baits (common range: #6–#1 for general use) | Mustad published hook size charts (industry-standard hook manufacturer) |
| Aught scale: 1/0 (smallest) up through 20/0+ (largest) | Gets LARGER as the number gets LARGER | Bass, catfish, and saltwater species — 1/0 is the size right after #1, not far away from it | Mustad published hook size charts (industry-standard hook manufacturer) |
| The transition point | #1 is the largest hook on the numbered scale; 1/0 is the next size up and the smallest on the aught scale | Remembering "#1 then 1/0" as one continuous size progression is the fix for the backwards-feeling system | Mustad published hook size charts (industry-standard hook manufacturer) |
Hook sizes run backwards on purpose: the numbered scale (#32 to #1) gets SMALLER as the number goes up, then the scale flips at the 1/0 'aught' boundary and gets LARGER as the number goes up (1/0 to 20/0+) — #1 and 1/0 are next to each other, not far apart. Full breakdown: Why Hook Sizes Go Backwards.
Split-shot / weight sizing
| Size range | Relative weight | Typical use | Source |
|---|---|---|---|
| BB / #7 | ~0.06–0.10 g equivalent range (smallest common split shot) | Panfish, finesse rigs, light current | Water Gremlin / Bullet Weights published split-shot size charts |
| #4 – #1 | Mid-range split shot sizing, larger than BB/#7 | General bait fishing, moderate current or depth | Water Gremlin / Bullet Weights published split-shot size charts |
| 3/0 and up (largest split shot) | Largest common split-shot sizes | Heavy current, deep bait presentations, larger baits needing more weight to hold bottom | Water Gremlin / Bullet Weights published split-shot size charts |
Caveats — read before citing a number
- Power and action are brand-relative, not physically standardized. A "medium" rod at one manufacturer can bend closer to another brand's "medium-light" — treat these tables as a strong general guide, not an exact cross-brand equivalence.
- Line test numbers are lab conditions, not guarantees. Knots, abrasion, UV exposure, and wet line all reduce real breaking strength below the printed rating.
- Gear ratio without IPT is an incomplete spec. Always check the manufacturer's stated inches-per-turn, since spool diameter changes the math.
- Reel size numbering (1000–5000+) is broadly standardized across Japanese-convention brands (Shimano, Daiwa) but not universal — always check the specific model's line-capacity spec, not just the size number.
- This table is general reference, not a durability, catch, or safety guarantee for any specific product or fishing condition.

Frequently Asked Questions
A normalized reference dataset covering the recurring spec systems anglers have to decode when buying rods, reels, line, and terminal tackle: rod power and action, line types and their true test-to-diameter reality, reel gear ratio and IPT, reel sizing, drag ratings, hook numbering, and split-shot sizing. It exists because most retail copy repeats these terms without explaining what they mean.
No — they are two independent specs. Power describes how much force it takes to bend the rod (what lure/line weight it's rated for); action describes WHERE along the blank it bends (tip only vs deep into the blank). A 'medium-fast' rod is medium power with a fast action — you need both words to know what you're buying.
There are actually two scales stitched together. The numbered scale (#32 to #1) gets smaller as the number increases; then at the boundary it switches to the 'aught' scale (1/0 to 20/0+), which gets larger as the number increases. #1 and 1/0 sit right next to each other in real hook size — the confusion is that the direction of the numbers flips exactly at that point.
Not necessarily. Gear ratio is turns-per-crank, but actual retrieve speed (inches per turn) also depends on the spool's diameter. A 7.0:1 reel with a larger spool can out-retrieve a 7.3:1 reel with a smaller spool. Check the manufacturer's published IPT figure, not just the ratio, when comparing across reel lines.
Not reliably. Braid's tensile strength per diameter is higher than monofilament's, so a 20 lb braid is often much thinner than 20 lb mono, and its true strength-to-diameter relationship differs from mono's. Compare line types by diameter and manufacturer spec sheet, not by test number alone.
