Gear Ratios by Spur Gear Size chart
Locate the spur gear size you want to know the ratios for then find the pinion gear size in the left column of that table. The ratio value is in the box to the right of the pinion gear. If the sizes you wish to know the ratios for are not here simply divide the spur gear teeth by the pinion teeth. The ratio is the number of revolutions the pinion gear makes for every one revolution of the spur gear.
