About Caliber
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.
Caliber is also given to girls.
Pronounced KAL-uh-ber.
As of October 2026, Caliber ranked #13798 for girls in US births in 2021 and #8366 for boys in US births in 2025 SSA, peaked at #13763 for girls in 2020 and #4005 for boys in 2016.
