Have you ever wondered if you have a crazy-big or wildly small foot? For men, it’s pretty easy to determine, as there are many studies analyzing the average size of a male foot.
Average Shoe Size for Men

In 2014, the American Academy of Orthopaedic Surgeons reported that the worldwide average shoe size for men is between 9 and 12, while the American average male shoe size is a 10.5.
How to Determine Your Shoe Size

To determine your shoe size, make sure to measure your feet at the end of the day when they’re the largest. The best method is to use a Brannock device or a ruler to determine your foot’s length and width, but every shoe has its own shape and fit that could affect the size you’ll need.

Do Your Feet Ever Stop Growing?

For most, feet will stop growing a few years after puberty or adolescence — for men, that’s around age 16. Your feet may continue to go up in shoe sizes, though, due to weight gain and loss of ligament and tendon mobility across a lifetime, according to Harvard Health Publishing.
