How to Find the Pitch of Chainsaw Chains

Turn off the chainsaw. Engage the safety lock. Unplug an electric chainsaw.

Closely inspect one of the links in the chain. Look for a part number or gauge number stamped on the link. Since different chainsaw manufacturers may use different numbering systems; you need to compare the stamped number to the manufacturer's pitch and gauge chart. These charts can generally be found in the chainsaw's manual or the manufacturer's website. An example is Oregon Chainsaws, which uses "11" to indicate a pitch of 3/4 inch. If you do not see the number marked proceed to Step 3.

Closely inspect the links of the chain. Measure from the center of one rivet in one link to the center of the rivet in the next link. There will be a rivet between these two end-point rivets; skip over this rivet.

Divide the distance number from Step 3 by two. In other words the pitch is the distance that lies between the first and third rivet, of any three rivets in a row, divided by two to get the pitch.
