Put them on and mark the desired shorts length
Add extra length for folding or fraying
Use chalk, a fabric marker, or pins to mark both legs evenly
Remove the jeans and smooth out the fabric
Cut one leg first along the marked line
Fold the jeans in half lengthwise and use the first cut as a guide for the other leg
Cut the second leg to match
Try them on and adjust the length if needed

Wash and dry the shorts to help fray the edges if desired
