Adam Ondra on the sport climbing route Silence, the hardest free climbing route in the world and the first-ever at 9c (French), 5.15d (American YDS), and XII+ (UIAA).. The two main free climbing grading systems (which include the two main free climbing disciplines of sport climbing and traditional climbing) are the "French numerical system" and the "American YDS system".

First-free-ascents that set new grade milestones are important events in rock climbing history, and are listed below. While sport climbing has dominated absolute-grade milestones since the mid-1980s (i.e. are now the highest grades), milestones for modern traditional climbing, free solo climbing, onsighted, and flashed ascents, are also listed.
Grade is usually expressed as a percentage - converted to the angle α by taking the inverse tangent of the standard mathematical slope, which is rise / run or the grade / 100. If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for flat, to 100% at 45 ...
The Yosemite Decimal System (YDS) is a five-part grading system used for rating the difficulty of rock climbing routes in the United States and Canada. [1] It was first devised by members of the Sierra Club in Southern California in the 1950s as a refinement of earlier systems from the 1930s, [2] and quickly spread throughout North America.
The most dominant grading systems worldwide are the 'French numerical' and 'American YDS' systems for lead climbing, and the V-grade and the Font-grade for bouldering. As of January 2025, the hardest lead climbing grade is 9c (5.15d), and the hardest bouldering grade is V17 (9A).
Topo image of the cliff Toix Est in Costa Blanca in Spain, by climber Chris Craggs from a Rockfax guidebook. Before discussing individual routes, a climbing guidebook will outline the history and current status of climbing ethics applicable for the location including for example whether the use of bolts for sport climbing is allowed, and other local customs (e.g. use if non-clean aid climbing ...
