Please see our Suspender Sizing Guide for a detailed explanation of how to measure to determine the right length suspender to purchase. We always recommend actually measuring the person who will be wearing the suspenders over using the height/weight size estimates. However in a pinch these guides usually result in the purchase of the right size suspender. Just remember that you can always shorten a suspender, but you can't lengthen it from the stated length. If all else fails, you can always exchange the suspenders for a different size - please see our Returns and Exchanges page for information on our customer friendly policies.
