Chainsaw Sharpening: How To Measure Chain Pitch
The pitch of a chain refers to the distance between its drive links.
It is determined by measuring the distance between any three consecutive drive links and dividing by two. Example: 3/4″ divided by 2 = 3/8″. Sometimes pitch is expressed as a fraction: 3/8″ and sometimes it is expressed as a decimal: .404″.
The pitch measurement of a saw chain helps reveal overall size of the chain–usually a larger pitch indicates a heavier and bigger chain.
The most common pitch used by professionals is 3/8″. It offers good flexibility, low weight, adequate strength, and good cutting speed.
Another popular pitch is .404″ and 3/4″ pitch chain.
Note: When replacing parts, keep in mind that the pitch of the chain, the pitch of the drive sprocket, and the pitch of the bar tip must all match.
