UIAA-Scale

The rating scale of the International Climbing Association and part of the SAC scales. It is represented here with Arabic numerals, which can also be upgraded by a plus (+) or downgraded by a minus (-). Thus, one digit contains three degrees of difficulty. Intermediate steps can also be added for a more precise definition. 7+/8- is then a difficult 7+ to easy 8-.

The UIAA scale is mainly used in sport climbing in Europe and preferably in western Germany. It is also very popular in climbing gyms.

The scale theoretically starts at 1 and now goes up to 11+. However, grades 1-2 do not necessarily require the use of hands and are therefore negligible in sport climbing. Very, very roughly, you can define the ranges 3-6 for beginners, 6-7 for advanced climbers, 8-10 for very good climbers and everything above that for the crème de la crème of climbing.
