I followed the sizing guide and chose a large size. When trying it on, the fingers were too short. It was like trying to put on a latex glove that was too small - it was impossible to spread your fingers, the tension on the palm and thumb was limited. The structures looked decent but were unusable. I replaced them with size XL Lincoln Premium TIG gloves which fit perfectly. I don't think I have particularly long fingers so I think I'll go up a size if you don't have short fingers.
