Basics of Chainsaw Sizes

When we talk about chainsaw sizes, we are essentially referring to two elements: the engine power and the guide bar length.

The engine power is measured in cubic centimeters (CC) or cubic inches for gas chainsaws, and volts (V) for electric chainsaws.

The guide bar length is measured in inches.

Chainsaw Bar Size

The chainsaw bar size refers to the length of the guide bar and generally ranges from 6 to 42 inches.

This measurement essentially dictates how large a log or limb you can cut in a single pass.
