Caliber Origin and Meaning

The name Caliber is a boy's name meaning "ability level; diameter of a gun barrel".

Caliber belongs to the class of tough boy names — along with Shooter, Wesson, and Trigger — that are given to a small but notable number of boys each year. We generally discourage parents from using such violence-promoting names — there are better routes to the nickname Cal.
