Why climbing grades are subjective guides rather than absolute measurements of difficulty
In short: In a climbing gym, colorful tape marks specific paths, but the numbers assigned to them are not absolute truths. Whether you are tackling a boulder problem or a long route, understanding the distinction between grading scales is essential for navigating the sport's complex hierarchy of difficulty.
Climbing difficulty is categorized into two primary systems. For bouldering, climbers use the V-grade system, which was invented by John the Verm Sherman. This scale originated in Waco, Texas, specifically within a bouldering area known as the Waco Tanks. Currently, bouldering grades begin at V0 and extend up to approximately V15 or V16, though the jump in difficulty between consecutive grades, such as V1 to V2, can be quite substantial.
When climbing routes rather than boulders, the Yosemite decimal system is used. This system originated in Yosemite, California. Grades typically begin at 5.3 or 5.4, which are considered beginner or intermediate levels. As difficulty increases, the scale moves through single numbers up to 5.9. Once a climber reaches the 5.10 level, letters (A, B, C, and D) are often added to denote subtle differences in difficulty within that specific number.
The scale continues upward to 5.15, with some of the hardest established climbs reaching 5.15 B or 5.15 C, though these are typically found outdoors. In a gym setting, climbers rarely encounter anything above 5.13. It is important to remember that grading is inherently subjective; variations in body type and the perspectives of different route setters mean that a grade is merely a guide. Falling on a lower-graded climb does not mean you lack skill, and you should never let a number deter you from trying something new.
Ultimately, these grades serve as a framework for progression. In a gym, following a specific color of tape allows a climber to track their progress through these various levels of difficulty.
