Determine the Pitch

To determine the pitch of a chain, you must register the distance between three of the metal studs. The studs are the steel pieces that connect the chain links. You must disconnect the chain from your chainsaw before attempting to measure it. Do so with utmost caution!

Lay your tape measure across a three-stud section of the chain. Do your best to straighten this portion of the chain before taking a measurement. Record the distance from the middle of one rivet to the middle of a third rivet. Divide your measurement in half.

The result of this equation should be a fraction of an inch. Manufacturers typically present a chainsaw’s pitch as a fraction or decimal. Popular chainsaw pitches include 3/8 inch, .325 inch, and 1/4 inch.

Determine the Gauge

Most manufacturers print the pitch and gauge measurements directly on the chainsaw. They may be engraved on the lower end of the bar or surface of the drive links. Oftentimes, these numbers are coded to account for limit space. You may need to refer to your user guide or reach out to the manufacturer to interpret these codes. You may also be able to find these codes online.

Determine the Length of the Bar

If you don’t have your chainsaw manual on hand, you need to measure your chainsaw bar. Before you stage your measurement, disconnect the chainsaw’s spark plug to prevent any accidental starts. Then, pull your tape measure so that it runs from the start of the bar to the end. The tape measure should be stretched tight.

Keep in mind that a portion of the bar is concealed beneath the chainsaw’s casing. As such, you may need to round up to the nearest inch. Common chainsaw bar lengths include 14, 16 (best 16 inch chainsaw review), 22, and 36 inches.
