A fishing reel’s gear ratio tells you how many times the spool, or the rotor on a spinning reel, turns with one full crank of the handle. Shimano’s guide explains that a reel marked 5.7:1 means the rotor makes 5.7 rotations around the spool for each complete turn of the handle. That simple number shapes how fast you pick up line, how much cranking power you have, and which techniques the reel handles best.

Short version: Abu Garcia calls 6:1 or less a “slow” reel, the better tool for cold water, deep-diving crankbaits and keeping a lure working longer. Shimano’s high and extra-high gearing brings line in fast for lure fishing and topwater work. Spool size matters too: a larger, full spool picks up more line per turn.

How Gear Ratio Works

Shimano’s reel guide describes the gear ratio as the number of rotor rotations around the spool per handle turn. In general, it says, lower gear ratios result in slower, deeper fishing, while higher ratios suit faster, surface fishing. Shimano describes its lower-ratio Power Gearing as offering ample cranking power and torque, while higher ratios trade some of that for speed.

Abu Garcia points out that what was considered a fast reel decades ago, a 5:1 ratio, is now viewed as slow. Today, ratios below 6:1 are relatively rare, and some models reach 10.1:1. The trend toward faster reels gives anglers more speed, but it also introduces a challenge: most people settle into a natural cranking rhythm. Abu Garcia calls this “comfortable revolutions per minute,” noting that about 120 turns per minute feels right for many anglers winding a crankbait or spinnerbait. That rhythm, combined with the gear ratio, determines how much line you actually retrieve.

Line pickup per turn is not just about the ratio. Abu Garcia’s “The Need for Speed” article highlights that larger spools and a full spool increase the amount of line gathered with each handle turn. A reel with a high gear ratio and a big, full spool retrieves line noticeably faster than a reel with the same ratio but a smaller or partially filled spool.

Matching Gear Ratio to Fishing Techniques

Shimano groups its reels into several gearing categories that illustrate how ratio affects performance. Power Gearing (PG) uses a lower gear ratio to deliver ample cranking power and torque. Shimano says PG reels are designed for jigging and deepwater bait fishing.

High Gearing (HG) strikes a balance between retrieve speed and power. Shimano describes HG reels as versatile tools for estuary, inshore, and offshore lure and bait fishing. They give you enough speed to pick up line quickly while still providing reasonable torque.

Extra-High Gearing (XG) provides ultra-fast retrieve speeds. Shimano notes that XG reels help anglers targeting fast-moving fish such as tuna, trevally, and mackerel with topwater presentations. The extra line pickup reduces slack and lets you stay in constant contact with the lure, so you can strike and set the hook immediately.

Abu Garcia offers specific situations where a slow reel, 6:1 or less, is the better choice. When water temperatures drop below 50°F, bass become lethargic, and a slower retrieve matches their metabolism. A moderate retrieve also helps deep-diving crankbaits reach their maximum depth; Abu Garcia states that a retrieve of 20 to 24 inches per turn gets crankbaits deeper, while anything faster can cause the lure to dive less. A slow reel also keeps a lure working effectively all the way back to the boat, which matters when strikes can happen at any point in the cast. Finally, if you struggle to slow down your retrieve, a low gear ratio acts as a built-in governor that prevents you from overworking the bait.

Gear Ratio Comparison Table

The table below summarizes how Shimano and Abu Garcia describe slow and fast reels.

Gear Ratio Category Typical Ratio Range Retrieve Speed (inches per turn) Typical Uses
Slow (Abu Garcia) / Power Gearing (Shimano PG) 6:1 or less (Abu Garcia) A 5.4:1 example gathers about 22 inches per turn; Abu Garcia wants 20 to 24 inches per turn for deep crankbaits Cold water, deep-diving crankbaits, keeping a lure working to the boat; jigging and deepwater bait fishing (Shimano)
High Gearing (Shimano HG) Higher than PG (Shimano gives no single number) Faster than PG Lure and bait fishing in estuary, inshore and offshore waters; balance of speed and power
Extra-High Gearing (Shimano XG) Fastest models reach 10.1:1 (Abu Garcia) A 10.1:1 example gathers about 41 inches per turn Topwater lures for fast-moving fish, constant contact with the lure

The retrieve speeds in the table are based on Abu Garcia’s example of a 5.4:1 reel pulling in roughly 220 feet of line per minute at 120 turns per minute (about 22 inches per turn) and a 10.1:1 reel pulling in 410 feet per minute (about 41 inches per turn). Actual line pickup varies with spool size and how full the spool is.

Gear Ratio Is One Piece of the Puzzle

Gear ratio matters, but it works alongside other factors. Spool size and how full the spool is change line pickup, as Abu Garcia notes, and the reel type (see our spinning vs baitcasting reels guide) and drag system shape how the reel handles a fish. Matching the reel to the rod and line you use ensures the whole outfit works together. Even the diving depth of a crankbait is influenced by retrieve speed, line diameter, and rod action, not just the reel’s ratio.

Fishing rules, including license requirements, gear restrictions, and size and bag limits, vary by state and body of water. Always check with your state wildlife agency before heading out.

Frequently asked questions

What does a fishing reel gear ratio actually measure?

Shimano’s guide explains that the ratio tells you how many times the rotor (or spool) turns for one full crank of the handle. A 5.7:1 reel means 5.7 rotations per turn.

Is a higher gear ratio always better?

Not always. Abu Garcia notes that while speed is often an advantage, a slow reel, 6:1 or less, is the right tool for cold water, deep-diving crankbaits, and situations where you need to keep a lure in the strike zone longer. Shimano’s PG reels show that lower ratios give more cranking power for jigging and deepwater work.

Does spool size affect how much line I retrieve?

Yes. Abu Garcia’s “The Need for Speed” article states that larger spools and a full spool increase line retrieval per turn. Even with the same gear ratio, a bigger or fuller spool picks up more line.
