Measuring the chain on your chainsaw accurately is crucial for ensuring optimal performance and longevity. An incorrectly sized chain can lead to inefficient cutting, excessive wear, and potential safety hazards. Therefore, understanding how to measure the chain properly is essential for any chainsaw user.
To start, determine the length of your chainsaw’s bar. This information is typically stamped or etched on the bar itself, usually expressed in inches or centimeters. The length of the bar directly corresponds to the appropriate chain length. Once you have the bar length, consult the manufacturer’s recommendations or refer to a chain length chart to find the compatible chain size. It’s important to match the chain size precisely to the bar length, as an excessively long chain may slip off the bar, while a chain that is too short will not engage with the guide bar properly.
Next, count the number of drive links on the chain. Drive links are the toothless links that connect the cutting teeth. To count the drive links, start at any point on the chain and count every other link until you reach the starting point again. This number represents the drive link count. Finally, add one to the drive link count to determine the total number of links in the chain. This value is known as the pitch, which indicates the spacing between the drive links along the chain. Common pitch sizes for chainsaw chains range from 3/8-inch to 0.404-inch. Matching the chain pitch to the correct drive sprocket on your chainsaw is essential for smooth and efficient operation.
How To Measure Chain On Chainsaw
Measuring the chain on a chainsaw is essential for maintaining its performance and safety. Here is a simple step-by-step guide on how to measure chainsaw chain accurately:
- Gather your tools: You will need a measuring tape or ruler.
- Position the chainsaw: Place the chainsaw on a flat surface, with the bar pointed away from you.
- Locate the drive links: Drive links are the links that have the teeth. Count the number of drive links on the chain. This will give you the number of cutting teeth on the chain.
- Multiply by two: The measurement for chainsaw chains is typically given in “pitch,” which is the distance between three consecutive rivets. To get the pitch, multiply the number of drive links by two.
- Read the pitch: The pitch is typically marked on the chainsaw bar. If it is not marked, you can measure it with a caliper.
Example: If you count 30 drive links and the pitch is 3/8 inches, your chain is 3/8-inch pitch with 30 cutting teeth.

What is the difference between pitch and gauge?
Pitch refers to the distance between three consecutive rivets on the chain, while gauge refers to the thickness of the drive links. Pitch determines the size of the sprocket on the chainsaw bar, while gauge determines the width of the guide bar groove.
How often should I measure my chainsaw chain?
It is recommended to measure your chainsaw chain every time you sharpen it or replace it. Measuring the chain ensures that it is the correct length and pitch for your chainsaw.
Can I measure the chain without removing it?
Yes, you can measure the chain without removing it. Simply count the number of drive links and multiply by two to get the pitch.
