    Belt Sizing Guide

    Your Billykirk belt size will be 2½ inches smaller than your waist circumference. We recommend measuring your waist to ensure an accurate fit. Here are two easy ways:

    Method 1: Using a Fabric Tape Measure

    1. Thread the tape measure through your belt loops where you normally wear your belt

    2. Keep the tape snug but not tight — leave space for one finger between the tape and your body

    3. Record your measurement in inches

    Method 2: Using String (Watch Video Tutorial)

    1. Wrap a piece of string around your waist through your belt loops

    2. Mark where the string meets and lay it flat against a ruler

    3. Record your measurement in inches
