The traditional thickness of a yoga mat is about 4-5mm. You just want enough cushioning so that the floor doesn’t feel too hard, and you can kneel without discomfort, but not so much that your feet are encased in the mat when standing, as this will make it hard to do balancing postures.
If you like a bit of extra cushioning and you shop around you can find a yoga mat that is a bit thicker than average – 6-8mm. Note that once you start getting to 15mm, you are in Pilates mat territory, and this will be too thick. That said, I do have a few students who use a thicker mat and it suits them fine.
Size of yoga mats is fairly universal (185cm x 60cm). However, if you shop around you will be able to find one that better suits your longer legs, or wider shoulders (we are all unique!).
