It may sound simple but trust me, when I was starting out I made plenty of custom belts that took hours of work only to get a message to say the belt didn’t fit!
Ive read plenty of instructions and guides and I still believe that the only true way to measure your belt is to do it the good Ol’ fashioned way with a tape measure.
I know, I know, you know your pants size… well let me let YOU in on a little secret..
Its not the same measurement as your belt size. Go on, go and check.
As a general rule your belt size is bigger than your waist, but lets not risk it and just measure instead.
Take a belt you already wear and measure as per our diagram below, that way neither of us will have to have a little cry when your custom belt has to become a nice wall hanging because its too small.
If you don’t currently have a non-stretchy belt that fits you well, use a cloth tape measure to measure the circumference of your waist (WITH pants on). Put the tape measure through the belt loops on your pants and pull it just a LITTLE snug. Note the measurement to the nearest inch (and again, round up if right on the half-inch).
The measurement you get with either of these methods is the size belt you should order, and will likely be larger than you think your waist is — this is normal. In most cases, a person’s measured circumference around their pants and through the belt loops, is 3″ to 6″ greater than their pants size.
