The measurement of a chain saw bar is different from the actual bar length. What this means is that the cutting length is not equal to the real chain bar length. While many people presume that the two measurements are the same, it is good to understand the importance of knowing the length of the chainsaw bar.
These measurements are very important, especially when it comes to replacing the chain bar. The measurements of the bar express the right cutting length of the saw and not the entire bar length that is a few inches longer. If looking forward to getting the right bar length, you need more than a tape measure.

Without a chainsaw, which is a small part of the tool, the entire is as good as dead. The chains rotate around the oval-shaped guide bar and it gets power from the motor.

By doing this, you can be sure that the machine will not turn on accidentally as you take the measurements.
Measuring the cutting length
It’s now time to measure the cutting length. All you need is to take out a measuring tape. Measure the bar’s length from the merging point t the tip of the chain. Ideally, this point is between 12 and 20. In case you get a fraction number, you can round it up to the closest number.
For example, align a measuring tape at the center across the bar. You can repeat this process severally if you have some doubts.
Measure the chainsaw actual length
