As with any garments, each brand of heated gloves might fit slightly different. With that being said, I haven’t come across any brand that is way off base when it comes to sizing.
Often times there are gloves that may fit slightly big or small but I’ll always be sure to mention that in my reviews. Unless otherwise stated in my review, you should use this guide to determine your size.
Measure in inches with a tape measure across your palm. You should use your dominant hand when measuring.
Some manufacturers will use a number for sizing and others will use letters ie. S, M, L, XL. The table below will help you translate between letters and numbers.
