Frequently Asked Questions
What is the YDS grading system?
The Yosemite Decimal System (YDS) rates rock climbing difficulty from 5.0 (easy) to 5.15 (hardest). Grades 5.10 and above use letter subdivisions (a-d) for finer distinctions.
How does V-scale compare to YDS?
V-scale is for bouldering (short, unroped problems) while YDS is for roped routes. V0 roughly corresponds to 5.10a, and difficulty increases are not directly linear between the two systems.
Which grading system should I use?
Use the system common in your area: YDS in the USA, French grades in Europe, and V-scale for bouldering worldwide. This converter helps when traveling or reading international route guides.
