Gear Tooth Span Dimension
Standard Span Measurement For Spur Gear Teeth

The following tables are for 1 Diametral Pitch Gears. To find the span measurement for other pitches, divide the span measurement by the desired pitch. The span numbers given are nominal and do not allow for backlash. To calculate the span reading for Circular Pitch or Module gearing, first convert to Diametral pitch and divide the span measurement by that number.
