Whatever your TRUE pants/waist size is in inches, go up one size for the perfect sized belt to the 3rd hole.
IF YOU SAG, we recommend going up 2 sizes from your TRUE pant/waist size.
Size 32 waist = Size 34 belt / Size 36 if you sag
Size 34 waist = Size 36 belt / Size 38 if you sag
A size 32 belt for a size 32 waist WILL BE TOO SMALL!
