How to Measure Your Chain and Bar

To ensure you get the correct chainsaw chain, you need to measure the pitch, the gauge and the drive links.

How to Measure the Pitch on a Chainsaw Chain

Sometimes the pitch is displayed on the guide bar but if you can't find it, the pitch can be calculated.

How to calculate the pitch on a chainsaw chain = Distance between any 3 rivets on the chain, divided by two.

How to Measure the Gauge on a Chainsaw Chain

The width of the drive link is the gauge. The gauge measures the thickness of drive links and is usually found on the chainsaw (often on the guide bar). It's important to match the right gauge to the chainsaw so that the chain fits properly into the guide bar.

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

To know the correct amount, the individual links need to be counted. The drive link count will correlate to the overall size of the bar (this can differ by manufacturer).

How to Measure the Length of a Chainsaw Bar

The length is from the bar emerging from the casing, to the tip of the bar.
