If you are not sure about your glove size, measure the hand you normally write with at its widest point in inches (excluding the thumb), then round down to the nearest half or whole number - this will be your glove size.
Gloves sizes come in half and whole numbers, between 7 and 11½ for men and 6 and 8½ for women. For example, if your hand measures 8½ inches around its widest point (excluding the thumb), your glove size is 8½.
If you are between sizes, choose the smaller size. Gloves should be snug at first but will stretch.
