A size 7 women's shoe is 9.25 inches long and a size 7 men's shoe is 9.625 inches long. These measurements correspond with the U.S. shoe sizing system.
For young children ranging in age from 9 months to 4 years, a size 7 shoe measures 5.5 inches. A size 7 shoe for children ages 7 to 12 years measures 9.75 inches.
To correctly determine shoe size based on foot length, stand barefoot on a piece of paper and closely trace the foot outline. Step away and measure the foot length from the tip of the longest toe to the heel. Foot measurements can also be taken using a Brannock Foot-Measuring Device.
