Bouldering grades are a way to measure the difficulty of climbing problems, which are short, challenging routes on rock walls. These grades help climbers understand what to expect and choose routes that match their skill level. The most common grading systems are the V Scale in the United States and the French Scale used in Europe. Each grade represents a range of difficulty, with lower numbers indicating easier climbs and higher numbers signifying more challenging ones. For example, a problem graded as V0 is easier than one graded as V5. Understanding these grades allows climbers to track their progress and set achievable goals.
