A 1" wide belt with two rows of regular 77 studs in a staggered pattern.
The belt in the picture is the one you will receive, is already made and is sized at 30", measured from the middle hole to the outermost tip of the buckle (see below).
Below is the my methodology for sizing. This belt is size 30.
DO NOT SEND YOUR JEAN SIZE FOR THE BELT!!
Measure using an existing belt from the end of the buckle hardware to the hole that you most frequently use. To be clear, if you lay out a belt with the buckle to the left, measure from the left-most part of the buckle up to the hole you use. Again, do not use your jean size.
If you would like to be double sure that the belt will fit perfectly, use the above method to measure a belt, enter that measurement when selecting the belt size and then leave a note on your order that says "Hi Sam! I wear size xyz jeans".
For this belt, 30" translates to roughly a size 24 jeans.
Belt returns well not accepted due to an incorrect measurement.
