I recently bought a pair of Altura Nightvision winter gloves in a large size, which seemed to fit OK in the shop. However I now find that when I have my hands wrapped round the handlebars my fingers are pushing up against the end of the tips of the gloves. This became really noticeable, and a bit uncomfortable, this weekend when I used my gloves on a long ride for the first time. I also ended up with cold finger tips! I did try the large gloves in the shop, but with my hands in an unfolded position they looked really big and a little silly, with perhaps 1cm between the tips of my finger and the tips of the glove. However I am now wondering whether I should have gone for the bigger size on the grounds that you need the extra space when your hands are clenched.
