Fishing Reel Gear Ratio Explained: Chart and Inches-Per-Turn Calculator
Fishing reel gear ratio explained: what 6.2:1 means, slow vs fast reels, which ratio for each lure, plus a calculator for inches per turn and feet per minute.
By De Pesca & Anzuelo editorial team
A fishing reel gear ratio tells you how many times the spool turns for each turn of the handle. A 6.2:1 reel turns its spool 6.2 times per crank, but the line you actually retrieve also depends on the size of the spool, which is why anglers talk about inches per turn.
Below: a calculator that turns any gear ratio into inches per turn and feet per minute, a chart of slow, medium and fast reels, which speed suits each lure, and what changes in salt water.
In short
- A 6.2:1 gear ratio means the spool (or the rotor, on a spinning reel) turns 6.2 times for every full turn of the handle.
- What you feel is inches per turn (IPT): gear ratio × spool size. Two 6.2:1 reels can retrieve different amounts of line.
- Slow (around 5:1) gives power and depth; medium (around 6:1) suits most lures; fast (7:1 and up) picks up slack for jigs and worms.
- A half-empty spool retrieves less line per turn, so keep your spool full.
- Salt water: a medium spinning reel covers most shore fishing; for big fish offshore, low gears give the cranking power.
Inches-per-turn calculator: what your gear ratio really means
Enter the gear ratio and the diameter of the line on a full spool. It starts with a PENN Battle IV 4000 (6.2:1), which PENN rates at 37 inches per turn; move the last slider to see how much speed you lose after a long cast.
What does a gear ratio mean on a fishing reel?
Inside the reel, a large main gear turns a small pinion gear; the ratio between their teeth is the gear ratio (Sport Fishing Magazine). On a baitcaster the pinion turns the spool; on a spinning reel it turns the rotor that wraps line around the spool. So 6.2:1 means 6.2 spool or rotor turns for every turn of the handle.
A lower ratio turns the spool fewer times but with more force, like a low gear in a truck. A higher ratio retrieves faster but with less cranking power.
Gear ratio vs. inches per turn (IPT)
Inches per turn is how much line comes back with one full turn of the handle. It is roughly the gear ratio multiplied by the circumference of the line on the spool, so a bigger spool retrieves more even at the same ratio (Sport Fishing Magazine, GetFishingEquipment).
- Fill the spool. A spool that is not full has a smaller circumference and retrieves less line per turn (Lew's).
- Expect it to change during the retrieve. Right after a long cast the spool is thinner, so the reel brings back less line; it speeds up as the lure gets closer.
- Compare IPT, not only the ratio, when two reels have different spool sizes. A tiny high-ratio reel can retrieve less than a larger, slower one.
Real reels compared: same gear ratio, different speed
We collected the gear ratio and the published line per turn of eight popular reels. The table shows why the ratio alone can mislead you:
- Four spinning reels at 6.2:1 retrieve anything from 36 to 39 inches per turn, depending on the spool size.
- A "slow" 5.3:1 offshore reel (Daiwa BG MQ 20000) brings back 53 inches per turn, almost twice as much as a "fast" 7.1:1 baitcaster (28 inches).
- Before you buy, read the inches per turn on the box, or enter the numbers in the calculator above.

Fishing reel gear ratio chart: slow, medium and fast
| Gear ratio | Line per turn* | Speed | Typical use |
|---|---|---|---|
| 5.1:1 | 20–22 in | Slow | Deep crankbaits, big swimbaits, cranking power |
| 6.3:1 | 25–27 in | Medium | Topwater, paddletails, spinnerbaits, live bait |
| 7.1:1 | 29–30 in | Fast | Jigs, worms, Carolina rigs, quick hooksets |
| 8.1:1 and up | 33 in and more | Very fast | Flipping, frogs, burning lures back between casts |
Which gear ratio for which lure?
- Slow (about 5:1 to 6:1): deep crankbaits dive deepest at 20–24 inches per turn; also big swimbaits and slow-rolled spinnerbaits (Abu Garcia).
- Medium (about 6:1 to 7:1): topwater, paddletails, spinnerbaits and live bait; the inshore all-rounder (Louisiana Sportsman).
- Fast (7:1 and up): jigs, worms, Carolina rigs, frogs, flipping and topwater, where you need to pick up slack quickly for the hookset (Lew's).
- Water temperature: slower reels in cold water, faster reels when it is warm, as a rule of thumb (Lew's).
How fast do you really reel?
Abu Garcia notes that most anglers drift back to the same comfortable pace, around 120 turns a minute, whatever reel they hold (Abu Garcia). That is why the calculator shows feet per minute: at 120 turns, a reel with 37 inches per turn brings back about 370 feet a minute, while one with 22 inches brings back about 220. If a lure works best slowly, a slower reel keeps you from rushing it without thinking.
Gear ratio for spinning reels and salt water
On spinning reels the numbers run lower: anything above 5:1 is already considered high speed (Sport Fishing Magazine). For most shore fishing in salt water, from rocks, jetties and piers, a medium spinning reel around 5:1 to 6.2:1 is the all-rounder; check the inches per turn on the box, since saltwater spools are larger.
Offshore, power matters more than speed. Big fish pull hard and long, and low gears give the cranking force; a 7:1 reel is not the tool for a 300-pound tuna, as one manufacturer puts it in the same article. Conventional reels such as the PENN Senator run at 2.5:1. For choosing the reel type first, see our guide to the types of fishing reels.
Reels by speed: our picks
One reel per job, chosen from the specifications, not from a lab test. Check the gear ratio printed on the box: many models come in several speeds.

Fishing reel gear ratio: frequently asked questions
What does a 6.2:1 gear ratio mean?
The spool, or the rotor on a spinning reel, turns 6.2 times for every full turn of the handle. It describes the gearing, not the exact amount of line you retrieve, which also depends on the spool size.
Is 5.2:1 a slow gear ratio?
Yes. Today anything around 5:1 is considered slow on a baitcaster. It retrieves roughly 20–22 inches per turn on a standard reel and gives more cranking power, which suits deep crankbaits and big swimbaits.
What gear ratio is best for bass fishing?
Most bass anglers carry two: a slower reel (around 5:1 to 6:1) for crankbaits and swimbaits, and a fast one (7:1 and up) for jigs, worms, frogs and flipping. A 6.3:1 to 7.1:1 reel is a sensible single choice.
What gear ratio should a spinning reel have?
Around 5:1 to 6.2:1 covers most fishing. On spinning reels, anything above 5:1 is already considered high speed, and the inches per turn on the box tell you more than the ratio alone.
What gear ratio for a baitcaster?
For a first baitcaster, a medium ratio around 6.3:1 to 7.1:1 is the most versatile. Go slower for crankbaits and faster for flipping and topwater.
What is a 7.5:1 gear ratio good for?
It is a fast reel: about 7.5 spool turns per crank. It suits lures you work with the rod and then reel in the slack, such as jigs, Texas-rigged worms and topwater, and helps you catch up when a fish swims toward you. It is tiring with deep crankbaits.
What is an 8.1:1 gear ratio good for?
It is one of the fastest ratios sold. Anglers use it for flipping and pitching into cover, frogs and burning lures fast near the surface, where picking up slack instantly matters more than cranking power.
What gear ratio do I need?
Match it to the lure and the fish: slow for deep, hard-pulling lures and big fish, medium for most lures and bait, fast for picking up slack line. Use the calculator above to compare the real inches per turn of the reels you are looking at.
