When it comes to chainsaws and chainsaw bars, the popular saying of one size fits all is far from it. Many first-time users and beginners often believe that a chainsaw bar of any length can also fit with a chainsaw of any length. This idea is false and should be completely downplayed. Chainsaw bars come in varying lengths which means not every chainsaw bar is right for every chainsaw engine. The length of a chainsaw bar is completely relative to the size of a chainsaw engine.
Large chainsaw bars are best suited to work for chainsaws with large engines. This is mainly because the chainsaw will require more energy to drive a chain across a lengthy chain bar.

How to Measure Your Chainsaw Bar
Finding the right chainsaw bar size for your chainsaw is a straightforward process. Start by placing your chainsaw on a flat, stable surface. Then measure the cutting length of the chainsaw bar this is the exposed portion of the bar, from where it emerges from the body of the saw to the very tip. Use a tape measure and round to the nearest inch if needed.

The length of the chain bar is an important factor to consider when buying a chainsaw. It is even more important when it comes to replacing a chain bar for a particular chainsaw. However, the length of the chain bar isn’t the only part of a chainsaw that requires measurement before replacement. The pitch and gauge of a chain also require measuring in the case of replacement.
Measuring The Pitch and Gauge of a Chainsaw
The pitch of a chain refers to the distance between the individual drive links of the chain. The gauge on the other hand is the width of the groove which helps to fit the chain on the chain bar. To measure the pitch, you’ll need to measure the distance between three rivets on the chain and then divide the number by two. The rivets of the chain are studs or pegs that hold together each segment of the chain.
Measuring the gauge can be a lot easier and quicker with the help of coins (a dime, a penny, and a quarter). Remember to clean out dirt or debris that may be stuck in the gauge of the chain. Place each coin into the gauge, and find out which of the coins fits perfectly into the gauge. Each coin represents a certain gauge measurement, a dime (0.50 gauge), a penny (0.58 gauge), and a quarter (0.63 gauge). This will help you determine the size of the gauge on the chain.
