The gears need to be of the same pitch. 81 and 19 will be 48 pitch, also available are 64 pitch, 32 pitch and various metric pitches (0.8, 0.6, 0.4)

Smaller pinion/larger spur = lower gear ratio for modified motors/small tracks
Larger pinion/smaller spur = higher gear ratio for stock motors/large tracks.
