Rubber track sizes are determined by: WIDTH (mm) x PITCH (mm) x LINKS (total #)

For example, here are three popular rubber track sizes:

• 180x72x38 (180 mm wide x 72 mm pitch x 38 links)
• 300×52.5×92 (300 mm wide  x 52.5 mm pitch x 92 links)
• 600x100x80 (600 mm wide  x 100 mm pitch x 80 links)

The rubber tracks for a Bobcat 316, for example, are sized 180x72x38. That means the track is 180 millimeters (7”) wide, with a 72 millimeter (2.8”) pitch length (or distance between the links), and a total of 38 links.
