The UIAA scale (or UIAA Scale of Difficulty) for free climbing was developed from the original "Welzenbach scale" in 1967 and uses the Roman numerals of that scale with "+" and "−" symbols for refinement between numerals after Grade III (i.e. III, IV−, IV, IV+, V−, V, V+ etc.,). [2] [3] Initially, the UIAA scale was closed-ended and went ...
The hardest boulder solved was at the boulder grade of V17 (9A) for men and V15/V16 (8C/8C+) for women. The hardest multi-pitch (or big wall) redpoint was at the grade of 9a+ (5.15a). The hardest single-pitch free solo was at the grade of 8c (5.14b), and the hardest multi-pitch (or big wall) free solo was at 7c+ (5.13a).
Bouldering problems are assigned numerical difficulty ratings by route-setters and climbers. The two most widely used rating systems are the V-scale and the Fontainebleau system.

The vertical exaggeration is given by: = where VS is the vertical scale and HS is the horizontal scale, both given as representative fractions.. For example, if 1 centimetre (0.39 in) vertically represents 200 metres (660 ft) and 1 centimetre (0.39 in) horizontally represents 4,000 metres (13,000 ft), the vertical exaggeration, 20×, is given by:
