Measure twice and cut once

phraseShop talkWoodworking

A fundamental rule of thumb reminding workers to verify dimensions before making an irreversible cut.

This classic proverb serves as a constant reminder that wood cannot be uncut once severed. Taking an extra moment to verify a dimension prevents wasted material, ruined workpieces, and lost time. In professional shops, it is often muttered as a self-correction or shouted at an apprentice who just ruined an expensive piece of hardwood.

Heard on the job

I know you're in a hurry to finish that baseboard, but measure twice and cut once, or we'll be short on trim.

Insider tip

A common joke when someone cuts a board too short is to tell them to go fetch the board stretcher, since they clearly only measured once.
