Fishing Reel Size Chart: Spinning Reel Sizes by Brand

Shimano

Shimano spinning sizes are 3- to 5-digit numbers (500, 1000, 2500, 3000, 4000 ... up to 30000 on Stella SW). The number is not a spool diameter: in Shimano Japan's 23 Stradic spec chart, the 2500, C3000 and 3000MHG all use a 47 mm spool, and the 4000 and C5000XG both use a 52 mm spool. A 'C' prefix marks a compact body: Shimano Japan describes the C2000S as a 2000-size spool on a 1000-size body and rotor. Suffix letters after the size give spool type and gear ratio (S = shallow spool, M = M spool, PG = power/low gear, HG = high gear, XG = extra-high gear, DH = double handle). US model numbers add a series prefix and a generation code (e.g. STC3000XGFM = Stradic, C3000, XG, generation FM).

• Shimano Japan describes the 23 Stradic C2000S as a model that mounts a 2000-size spool on a 1000-size body and rotor (「1000番サイズのボディ＆ローターに2000番サイズのスプールを装着」).
• Shimano Japan describes the 24 Twin Power C2000SHG as a high-speed model on a 1000-size body (「1000サイズのボディにハンドル一巻き81cmのハイスピードモデル」).
• The 3000MHG is the exception that goes the other way: Shimano Japan describes it as a 3000 model that puts a compact 2500-class spool and rotor on a 4000-class body, and says its spool is interchangeable with the 2500 and C3000.
• Spool diameter / stroke in the 23 Stradic (Japan) spec chart: C2000S/C2000SHG 43/13.5 mm; C2500S/C2500SXG 44/13.5 mm; 2500S/2500SHG, C3000/C3000HG/C3000XG and 3000MHG 47/17 mm; 4000/4000MHG/4000XG and C5000XG 52/19 mm.
• Because the 2500S and C3000 share the 47 mm spool, the difference between them in the 23 Stradic is spool depth: the 2500S is rated PE 0.6-200 m / 1-120 m, while the C3000 is rated PE 1-400 m / 2-200 m (Japanese PE numbers).
• Weights in the same chart: 2500S 220 g, C3000 225 g, 3000MHG 245 g, 4000 275 g, C5000XG 290 g.
• US model numbers carry a series prefix and generation code: the US Stradic FM lineup is ST1000HGFM, ST2500HGFM, STC3000XGFM, ST4000XGFM and STC5000XGFM.
• A shallow-spool 'S' model in the US: Shimano North America says the new Vanquish 2500S 'features a shallow spool arbor engineered specifically for ultra-thin braid'.

Daiwa

Most current Daiwa spinning reels use LT sizing. Daiwa US defines LT as 'Light and Tough' (a smaller body with a larger DigiGear). In LT sizing the number maps to a fixed spool diameter: SF/LT1000 = 40 mm, SF/LT2000 = 42 mm, SF/LT2500 = 45 mm, LT3000 = 48 mm, LT4000 = 51 mm, LT5000 = 54 mm, LT6000 = 57 mm. After the size come spool depth (D deep, none standard, S shallow, SS extra shallow, SSS ultra shallow), an optional -C for a body one size smaller, the gear ratio (P, none, H, XH) and handle options (DH double handle, QD quick drag). Daiwa Australia's sizing table shows that LT numbers are not the same as Daiwa's older (pre-LT) numbers.

• Daiwa US glossary: 'LT — Light and Tough. Smaller body design yet with larger DigiGear drive for the perfect combination of lightness and toughness.'
• Daiwa Japan's LT/SF model-number chart gives spool diameters: SF/LT1000 φ40 mm, SF/LT2000 φ42 mm, SF/LT2500 φ45 mm, LT3000 φ48 mm, LT4000 φ51 mm, LT5000 φ54 mm, LT6000 φ57 mm.
• Daiwa Japan's chart reads a model number such as EXIST FC LT2500S-CXH-DH as: series / special code (FC = Finesse Custom, PC = Power Custom, ST = Sensitive Tune) / size (spool diameter) / spool depth (D = deep, none = standard, S = shallow, SS = extra shallow, SSS = ultra shallow) / -C (compact: a body one size smaller) / gear ratio / handle code (DH = double handle, QD = quick drag).
• Daiwa Japan's gear-ratio bands: P = 4.9 or lower; no letter = 5.0-5.4; H = 5.5-5.9; XH = 6.0 or higher.
• Daiwa Australia's LT sizing table puts old and new sizes on the same spool-diameter scale: old 1000 = 40 mm, old 2000 = 43 mm, old 2500 = 48 mm, old 3000 = 54 mm, old 3500 = 55 mm, old 4000 = 57 mm; LT1000 = 40 mm, LT2000 = 42 mm, LT2500 = 45 mm, LT3000 = 48 mm, LT4000 = 51 mm, LT5000 = 54 mm, LT6000 = 57 mm. So an old Daiwa 2500 matches an LT3000 in spool diameter, an old 3000 matches an LT5000, and an old 4000 matches an LT6000.
• Daiwa Australia says the varied gaps between old sizes worked when monofilament was standard, but braid lets anglers use smaller reels effectively, so LT standardises spool diameters and 'expands 4000 to 6000'.
• Daiwa also re-sized heavy saltwater reels starting with the 20 Saltiga, so that two reels with the same number no longer have very different capacities (Daiwa's example: Certate LT 5000 at PE 2/300 m vs 15 Saltiga 5000 at PE 5/300 m). The 15 Saltiga 4500/5000/5500/6500/8000 correspond to the 20 Saltiga 8000/10000/14000/18000/20000.
• Daiwa's European guide: 'The higher the number, the larger and stronger the reel, with more line capacity and drag power.' It explains the letters as no letter = standard ratio, H = High speed, XH = Extra High speed, P = Power (a slower ratio with more torque).

PENN

PENN's online Reel Size Guide lists spinning sizes from 1000 to 10500 in steps of 500, each matched to a fishing type and species size. On current models such as the Battle IV, the 'HS' suffix marks a High Speed version of a size (BTLIV4000HS at 7.0:1 vs BTLIV4000 at 6.2:1). PENN does not say whether its numbers line up with Shimano or Daiwa sizes.

• PENN's Reel Size Guide (shown on its spinning-reel product pages) covers sizes 1000, 1500, 2000 ... 10000, 10500, and lists a fishing type and example species for each.
• Battle IV is offered in sizes 1000, 2000, 2500, 3000, 4000, 5000, 6000, 8000 and 10000, in Standard Speed and High Speed versions (e.g. BTLIV4000 6.2:1, BTLIV4000HS 7.0:1; BTLIV6000 5.6:1, BTLIV6000HS 6.2:1; BTLIV8000 4.7:1, BTLIV8000HS 5.3:1).
• No PENN page we found states an equivalence between PENN sizes and Shimano or Daiwa sizes.

How to read this reel size chart

Each dot in the chart is one current US model plotted at its nominal size against its published weight. Rows in the table group models by the number in their name, so a Shimano C3000 sits in the 3000 row and a Daiwa LT4000D-C sits in the 4000 row. Reading across a row compares brands at the same label; reading down a column shows how one series steps up.

The spread inside a single row is the first thing to notice. At 3000, the Vanford C3000XG is listed at 6.3 oz, the Sedona C3000HG at 8.6 oz and the Battle IV 3000 at 11.6 oz. The number sets the spool class; it says nothing about the build or materials of the reel around it.

The braid figure in each cell is the first rating that brand prints, and brands pick different line strengths to quote. Shimano leads its C3000 rating with 10 lb braid, PENN leads its 3000 with 15 lb. Compare capacity at a matching line strength, not first number to first number.

Why a 3000 is not the same reel across brands

Shimano's number is not a spool diameter. In the 23 Stradic chart the 2500, C3000 and 3000MHG all use a 47 mm spool, and the 4000 and C5000XG both use 52 mm. The C prefix means a compact body: the spool named in the number sits on a body one size smaller.

Daiwa's LT system does tie the number to diameter: LT2500 is 45 mm, LT3000 is 48 mm, LT4000 is 51 mm. Older Daiwa sizes ran larger, so an old Daiwa 2500 matches an LT3000 in spool diameter and an old 3000 matches an LT5000. Anyone replacing a pre-LT Daiwa like for like should expect a higher LT number.

Set side by side, the two official charts put Shimano's 2500/C3000 spool between Daiwa LT2500 and LT3000, and Shimano's 4000/C5000 spool between LT4000 and LT5000. That comparison is derived from both charts rather than stated by either maker, and diameter is only one dimension; spool depth and stroke also set capacity.

• Shimano C3000: a 3000-class spool on a smaller body, with a 47 mm spool in the 23 Stradic chart.
• Daiwa LT3000: 48 mm by definition. A -C suffix, as on the BG LT4000D-CXH, puts the named spool on a body one size down.
• PENN 3000: a step on PENN's own scale, defined by species and line ratings rather than a published spool diameter.

2500 vs 3000 spinning reel: what actually changes

On a Shimano reel the 2500 and C3000 share spool diameter and stroke, so the step is depth. At Japanese PE 1 braid, the 23 Stradic 2500S is rated for 120 m and the C3000 for 400 m, while the Japanese chart lists them at 220 g and 225 g. In the US Stradic FM, the ST2500HGFM holds 120 yd of 10 lb mono and the STC3000XGFM holds 140 yd at the same strength, for 7.8 oz versus 7.9 oz.

Daiwa and PENN make the step larger. Daiwa's LT2500 to LT3000 is a real diameter change, and the BG LT goes from 8.5 oz to 9.3 oz. The Battle IV moves from 9.7 oz and 12 lb of max drag at 2500 to 11.6 oz and 15 lb at 3000.

Manufacturer guidance splits the two by use. Shimano Japan calls the 2500S its standard bass model and the C3000 a versatile freshwater-to-saltwater model; PENN lists its 2500 for light inshore and its 3000 for medium inshore fish. Shimano North America names either size for walleye, pike and trout, which marks the overlap zone where line choice should decide.

Pick the size from your line first

Bass Pro 1Source's buying guide puts it plainly: the lighter the line, the smaller the reel, and the reel should be rated for the line you use most. Manufacturer capacity ratings make that rule concrete. The ranges below use the Stradic FM because it covers 1000 through C5000 in one series, with PENN Battle IV ratings for the heavier end.

• 2-6 lb mono: 1000 class. The ST1000HGFM is rated for 2 lb/270 yd, 4 lb/160 yd and 6 lb/110 yd.
• 6-10 lb mono or light braid: 2500 to C3000. The STC3000XGFM runs from 6 lb/230 yd to 10 lb/140 yd.
• 10-12 lb mono or 15-50 lb braid: 4000. The ST4000XGFM lists 50 lb braid at 120 yd.
• 12-14 lb mono: C5000. The STC5000XGFM is rated 12 lb/195 yd and 14 lb/165 yd.
• Heavy braid for big saltwater fish: PENN 6000 and up. Battle IV ratings reach 80 lb braid on the 8000 and 10000.

What size spinning reel for bass, surf and other fish

Bass is the most consistent answer in the source data. Shimano North America describes the Exsence 2500XGB as built for finesse bass, Shimano Japan treats the 2500S as its bass standard, and Daiwa Japan lists LT2500 and SF2500 for bass, with LT3000 also on its list. A shallow 2500S spool, such as the one on the Vanquish, is Shimano's answer for very thin braid.

Surf is where sources disagree most, because they describe different fishing. PENN lists 6000 through 8500 for nearshore and surf, 9000-9500 for heavy surf and 10000-10500 for extreme surf. A Shimano North America column on New England fall surf pairs a long-cast 5500 Ultegra XR with 30 lb PowerPro, and Shimano Japan calls the Stradic 4000XG its standard model for Japanese surf lure fishing. For bait, that same Shimano column asks for a reel holding at least a couple of hundred yards of 30-50 lb braid.

A 1000 is a light-line reel: Shimano North America suggests a Nasci 500 or 1000 for panfish, and PENN lists its 1000 for small inshore fish. A 4000 is PENN's inshore, pier and nearshore size and Daiwa's upper pike size.

Reading a PENN reel size chart

PENN's online Reel Size Guide runs from 1000 to 10500 in steps of 500 and attaches a fishing type and species examples to each step. The Battle IV uses mostly whole-thousand sizes, while the Spinfisher VII and Slammer IV use the half-steps: 3500, 4500, 5500 and so on.

PENN's spec tables show that capacity follows the size number across these three series. The Spinfisher VII and Slammer IV list identical mono and braid ratings at every size they share, and the Battle IV 2500 matches both at 2500. What separates them is sealing and drag hardware, not line capacity; the three-way comparison covers those. An HS suffix marks a faster version of the same size, such as the BTLIV4000HS at 7.0:1 against 6.2:1.
