Chain size finder

Chainsaw chain size chart & finder

A chain is defined by three numbers: pitch, gauge and drive links. Type your saw model, or pick the numbers stamped on your bar, to see the size and every other saw that shares it.

Source: Oregon part-finder fitment data, retrieved 2026-07-06: 1478 models from 16 brands whose Oregon chain recommendation includes a drive-link count. Sizes are read from Oregon's chain part numbers (e.g. 91PX052G = 3/8" LP, .050", 52 DL). Sizes shared by fewer than 5 models are listed but thin. Saw not here? Its bar stamp or owner's manual has the numbers.

Reading the three numbers

  1. Pitch is the spacing between rivets: 1/4", 3/8" Low Profile, .325", 3/8" and .404". 3/8" LP and full 3/8" are different chains.
  2. Gauge is the drive-link thickness that rides in the bar groove: .043", .050", .058" or .063".
  3. Drive links set the loop length. Count them on the old chain — two 16" bars can take 55, 56 or 57 links.

All three are usually stamped near the tail of the guide bar.
