Quick overview
Use this free Carry Gun Size Guide to provide a quantified match between a person's body measurements and a firearm's physical dimensions. Enter your measurements and a firearm's specs to generate a Fit Score and an easy-to-understand recommendation (Excellent, Good, Borderline, Not Recommended).
How it works
The calculator normalizes your body measurements (height, waist, weight, inseam, arm length, torso length) into a Body Profile Index and transforms the firearm's specs (weight, overall length, height, width, grip circumference) into a Firearm Concealability Index. A combined Fit Score estimates how well a firearm will conceal for your body shape. This is an estimator — always verify comfort, legal requirements, and safe carry practices with a qualified instructor.
