If you have beefy hands, width size is more important.
If you have long fingers, finger length is more important.
Step 1: Measure the length of your middle finger on the palmside.
Step 2: Lightly wrap a string/tailor's tape around the widest part of your knuckles.
Remember, your gloves will break in — BUT mostly in the width of the fingers and hand. They don't magically get longer.
