When millimeter precision matters

Millimeters are the unit of choice whenever a centimeter is too coarse — small parts, wire gauges, screw sizing, jewelry, and detailed technical drawing all rely on 1mm resolution. This ruler labels every centimeter and marks every individual millimeter in between.

Need a longer ruler?

Use the custom ruler builder to generate longer millimeter-precision rulers — lengths beyond one sheet are automatically tiled with alignment marks.
