Climbing V Scale To Font Conversion Calculator

Two bouldering grading systems exist: they are just used differently depending on where you climb. In the US we have the V scale with a starting grade of V0, then moving through the teens to reflect the most difficult problem. Most of the rest of the world, including Europe, has the Fontainbleau system (Font) where the grade reflects letters and plus (+) signs that denotes difficulty.

While there’s not a 1-1 swap between the two because they arise from distinct cultures of climbers and kinds of rock, a climber used to climbing outside on V6 may find themself facing something else entirely when faced with same number in a Font graded book. But it’s not math. Even though numbers may be close on paper, the feeling of the problem change based off style, setting and local agreement.

How to Use Boulder Grade Conversion

For example, a powerful climber may find a steep compression problem in a gym easier than a technical slab of similar grade. And there are other variables such as outdoor rock texture, skin conditions and the fact that guidebooks was written decades ago. As a result, most climbers use any given conversion as a starting range but not a fixed target.

When switching from this system to that, it’s useful to think in ranges. In some settings a V8 might be perfectly comfy in Font 7B; in others it feel more like a 7B+. That comes into play when you’re planning a trip and want to know what will keep you warm, compared to what is going to take a lot of work.

Input the benchmark feel of the problem along with the dominant movement style, setting, and direction of conversion. The calculator do those adjustments for you and allows you to preview one or two harder grades. This gives you a chance to construct a realistic pyramid rather than just guess at the next step.

This is something many climbers learn early in their traveling days. They show up and expect to onsight everything one grade higher at home, only to find out the locals are sandbagging it or they reset all those problems while stuck indoors climbing on plastic for months. That’s where the practical range the calculator spits out comes in. It helps you know how to deal with your uncertainty, and not freeze every decision until you’ve gotten up there yourself.

It also helps remind you of what matters. Recent sends at a grade are worth more than a quick flash, when considering if something is realistic. This is also true for training at home. Fingers on boards are often stiffer than they would be outdoors, whereas gym sets can feel soft depending on how much use the setter want.

By making adjustments based on style and context, you can let the output reflect these real differences rather than force everything onto one universal chart. With time, this allows you to know what adjustments is important to your specific strengths and which ones you can largely ignore. And used like this, conversion ceases to be a lookup task.

It’s part of your planning process. You input your known grade and add information about what kind of rock or plastic you’re actualy dealing with up there. Out comes a workable window. It is not exactly precise, but it is typically honest enough to keep moving onward rather than second-guessing each number on the wall.
