What Is the Guide Bar of the Chainsaw?
The guide bar of the chainsaw is its steel part that you see directly coming out of the motor. It is oval-shaped, and the chain rotates over it to help in cutting.
The bar is important as it is the component that keeps the chain in place and makes the chainsaw a successful tool.

Tools Needed to Measure the Bar
How to Measure the Chainsaw Bar?
- 1Make sure the chainsaw is stable on a flat surface. Take out the spark plug wire to avoid potential accident while you are working on the measurements.
- 2Start measuring the chainsaw bar with the help of the measuring tape. You should measure from the beginning of the bar to the very tip. If the measurement isn’t an exact figure, please round it to the nearest inch. Also, you may search common chainsaw bar sizes on the internet to check some results.
- 3Many companies like to have the full length of the bar rather than just the protruding part. In that case, you can take the whole bar out by using a ratchet and socket on the chainsaw. Then measure the whole thing using a measuring tape.
When the chain gets eroded or damaged, it needs to be changed immediately.
How to Measure the Chain on Your Chainsaw?
- 1First, we have to find the ‘pitch’ and ‘gauge’ of the chain that we are using.
- 2Pitch is measured using the distance between any 3 consecutive rivets and then divide it by 2. Rivets are small studs holding the chain segments together.
- 3The gauge can be measured easily with the help of a quarter, a dime or even a penny. Clean the grime or oil that is present between the bar and the chain.
- 4When it is done, use the coins in the bar grooves to see which has the most snug fit. Do not force the fit as it should go smoothly. A quarter stands for a gauge of 0.063, a penny for 0.058 gauge and a dime for 0.50 gauge.
- 5Then you use a chainsaw chain chart to find the right chain size for your chainsaw.
- 6Most companies these days provide the chain information on the bar itself. So, check the bar carefully for the sizes. Then you may use the Selector Guide to find out the parts of your chainsaw.
We hope that with our guide you manage to learn how are chainsaw bars measured. Follow the steps carefully to get the best results out of it.
