Chain pitch refers to the distance between three consecutive rivets, determining overall chain compatibility. The most popular sizes include 3/8" LP low profile chain for light tools, 0.325 for medium-duty cutting, and 0.404 for heavy-duty industrial logging. Each pitch is designed to match different chainsaw power levels and bar sizes, covering household, landscaping, and commercial forestry scenarios.
Gauge means the thickness of drive links, including 0.043, 0.050, 0.058, and 0.063 inches. Thinner gauges fit lightweight electric saws and small gas saws, while thicker gauges are used for high-power machines and heavy wood cutting. Matching the bar groove width is the key to avoiding chain shaking and abnormal friction.
The chainsaw chain size chart also distinguishes tooth styles: full chisel chain and semi chisel chain in each size series. 0.404 and 0.325 sizes are widely available in full chisel versions for fast logging, while 3/8" LP mostly uses semi chisel and low-profile structure for safe pruning.
