How to Measure Your Chain and Bar

To get the right chainsaw chain, measure the pitch, gauge, and drive links.

How to Measure the Pitch on a Chainsaw Chain

The pitch may be marked on the guide bar. If not, you can calculate it.

To calculate the pitch on a chainsaw chain, measure the distance between any three rivets on the chain and divide by two.

How to Measure the Gauge on a Chainsaw Chain

The gauge is the width of the drive link. It measures the thickness of the drive links and is usually found on the chainsaw, often on the guide bar. Matching the correct gauge to the chainsaw is crucial for proper fit into the guide bar.

How to Identify the Number of Drive Links on a Chainsaw Chain

Count the individual links to determine the correct amount. The drive link count corresponds to the overall size of the bar, which can vary by manufacturer.

How to Measure the Length of a Chainsaw Bar

Measure from where the bar emerges from the casing to the tip of the bar.
