A Handy Guide On How to Measure Chainsaw Chain Length


The most important factor you have to think about when you have to change your chainsaw’s chain is the length. You may purchase a chain of the highest quality but if it won’t fit, it will be useless. That’s why we’re here to teach you how to measure chainsaw chain length.

According to SFGate Home Guides, the chain length matches with the measurement of the chainsaw’s bar. In fact, some companies sell their replacement chains based on bar measurement.

To get your chainsaw’s bar measurement, place your tape measure along the metal surface. See to it that one end is on the tip while the other touches the spot where the bar emerges from the casing.

If you’ll get an odd or fractional measurement, round it up to the nearest even number. Expect to get 16, 18 or 20 inches since these are the typical bar measurements.

To guarantee that you’ll get your hands on the best chain for your chainsaw, you may also take note of the pitch and the drive link count. Find out how:

Count the links protruding from the chain.

This process requires removing the chain from the bar. Then, you should stretch it on a table or any flat surface for a more accurate count.

Next, observe the chain’s underside. You’ll surely see the links emerging. Simply count them all.

Calculate the chain’s pitch.

Continue observing the chain so you can easily spot the bolts or rivets holding the assembly together. Starting from the center of any rivet, extend the tape measure until it reaches the center of the third rivet. That means your tape measure must cover three consecutive rivets anywhere around the chain.

After getting the measurement, divide it by 2. That’s it!


In case you got confused, we’re going to review how to measure chainsaw chain length. The standard is to measure the chainsaw’s bar only. However, to guarantee that you’ll buy the right chain for your tool, it is highly recommended to get the drive link count and the pitch as well.
