Terminologies Used in Measuring a Chainsaw Chain
It is what your chainsaw’s chain spins on and sit. It comes a flat metal with a grooved section where the saw drive links get located.
- Drive Links
Drive links get fitted into your chainsaw’s bar groove and get used to secure the bar. You will find them located along the chain’s bottom, at the opposite of the cutting teeth.
It refers to the drive links’ thickness. It helps prevent the chain from getting off the bar.
It is the distance between your chainsaw’s drive links
To effectively measure the length of your chainsaw’s chain, the combined knowledge of the above terminologies is a must.

|11/64” (4.5mm)||3/8” x .043” (1.1mm)||90|
|3/16” (4.8mm)||All .325” chains||20, 21, 22, 95|
|7/32” (5.5mm)||3/8” x .058” (1.5mm)

Step by Step Measuring Guide of a Chainsaw Chain
Fortunately, the process is fast and straightforward. You only need to follow the following steps;
Step 1: Take the Bar’s Measurement
First, ensure the chain and bar are on to get a general number of the chain size and bar replacement. Measure the length of the chainsaw’s bar to determine the bar size.
Start from the saw’s front to the last cutting tip. Then round up the gotten measurements to the nearest inch. The result is called the ‘length,’ which the manufacturers refer to as an 18″ chainsaw, for example.
Step 2: Pitch Measuring
To measure the pitch, you’ll have to take three consecutive rivets and measure the distance. Then divide what you get by two to get the pitch. If the number is large, it means that the space between the links is large. As a result, the saw becomes aggressive and faster when cutting.
A smaller number indicates that the saw gets used in removing small chunks of wood at a particular time, and get meant for home use.
Step 3: Gauge Measuring
Gauge measuring is tricky, and it’s, therefore, advisable to check the chainsaw’s user manual or bar. If you can’t find any of these, you then go ahead and use a method called “trick of the trade.” In this method, you get the coins and put them inside the bar groove.
Let the coin slide in snug effortlessly. If it’s a penny and slides without forcing it, then the gauge is 0.058″. For the dime and quarter are 0.050″ and 0.63″ consecutively. Though not common, some chainsaws come with a 0.043″ gauge.
Step 4: Counting the Drive Links
To ensure you replace the chain with the correct size, you need to count the drive links. You can do so by either removing the chain or loosening and spinning it. Ensure you mark where you start counting with something sharp.
As described above, you may need to change your chainsaw’s chain after some time. If your chainsaw doesn’t come with the measurements or have gotten worn out, the above step by step guide will help you get the correct size of your chainsaw chain.
