Perforation Counting Guide

Perforations are measured by counting the number of teeth (or holes) per 2cm along one edge.

Perf 10

Common on early US issues (1847-1890s)

Perf 11

Standard for many US commemoratives

Perf 12

Common on US definitive issues

Perf 10 x 12

Compound perforation (differs by edge)

Perf 11 x 10.5

Many US airmail stamps

Imperforate

No perforations; cut with scissors (rare)

Use a perforation gauge (perf gauge) for accurate measurement. A Stanley Gibbons or Scott gauge is standard.

Value Factors

Centering

Design equidistant from all edges. Perfect 50/50 is ideal. Off-center stamps lose significant value.
