Goalkeeper gloves should be roomy, generally 1/2 to one inch past the end of your fingertips. Goalkeeper gloves that fit tightly are more prone to blowouts or holes around the fingers or palm. To determine your goalkeeper glove size:
1)Measure the circumference of the part of your palm just below your knuckles, without your thumb.
2) Round up to the next whole inch, and then add 1 to determine your size.
3) Measure both hands, and if the measurements are different, order the larger size for the most consistent fit.
