Why Grades Vary
Climbing grades are subjective and vary by region, rock type, and era of first ascent. A route graded 5.11 in Yosemite may feel like a 5.12 in Gunks, New York, due to different climbing style requirements. Grade conversions are approximate — treat them as guidelines, not exact equivalences.
Frequently Asked Questions
Is this climbing grade comparison free?
Yes, completely free with no signup required.
What is the hardest rock climbing grade?
The current hardest grades are 9c (French) = 5.15d (Yosemite) = XII- (UIAA). As of 2025, only a handful of routes worldwide have been graded 9c.
What grade should a beginner climb?
Most gym beginners start on 5.5–5.8 (Yosemite) / 3a–5a (French) routes. Intermediate climbers project 5.10–5.11 / 6a–6c. Advanced climbers work 5.12–5.13 / 7a–8a. Route grades are set by the first ascensionist and can vary by location.
What is the difference between sport and trad grades?
Grade comparisons apply to both sport and trad climbing. However, trad grades often feel more serious due to protection considerations — a 5.10 trad route may feel harder than a 5.10 sport route at the same fitness level due to the mental challenge of placing gear.
What is the Yosemite Decimal System?
The Yosemite Decimal System (YDS) rates technical climbing from 5.0 (easiest) to 5.15d (hardest). Class 5 means ropes and protection are needed. The most common difficulty range is 5.5 to 5.13. The decimal expanded when routes became harder than 5.9.
