Determine the correct chainsaw chain length and drive link count based on your bar length, pitch, and gauge.

Frequently Asked Questions

How do I count drive links on my current chain?

Count the number of drive links (the tabs that fit into the bar groove and sprocket) all the way around the chain loop.

What is chain pitch?

Pitch is the distance between three consecutive rivets divided by two, common sizes are 1/4, .325, 3/8, and .404 inch.

Why does bar tip adjustment matter?

The sprocket at the bar tip reduces the usable cutting length slightly, which affects the total chain loop length needed.
