Bouldering Grades - The Complete Guide

While it’s not the oldest type of climbing, bouldering is among the most modern forms of climbing. It doesn’t necessarily need ambiguous knots and tall walls, and it’s an excellent way to learn and train or pass the time. 

Even so, this sport needs some expertise to get the most from it. Nevertheless, today we take a look at bouldering grades. From beginners to professional boulderers, bouldering grades can be a bit complicated. 

To help you out, we’ve written this comprehensive guide on bouldering grades. Therefore, if you’re new in bouldering or simply don’t understand bouldering ratings, this is what you need to know;

What Are Bouldering Grades?

Also known as bouldering ratings, bouldering grades are a combination of numbers and letters utilized to determine the intricacy of boulder issues. These ratings are given to problems for both outdoor and indoor bouldering. 

When it comes to outdoor bouldering, the two major rating scales used are the Font and V scales. On the other hand, indoor bouldering and climbing gyms utilize the Front and V scales or develop their grading mechanism. 

For instance, a bouldering gym could rate difficulty from 0 to 4. The former is the most effortless stage, perfect for novices, and the latter is the most challenging for professional climbers. 

Why Are Bouldering Difficulties Rated?

Bouldering ratings were engineered as a means to specify the difficulty of each bouldering level to an individual who’s never tried it. 

Practically, ratings come in handy in aiding boulderers to better understand the difficulty of each stage before trying it out. They also help you identify which stage you can easily maneuver and those too challenging for you. 

For example, if V5 issues are challenging but achievable for you, obviously a V3 will be simple, a V6 might put your skills to the test, and a V9 will most probably be too difficult for you. Furthermore, rating boulder problems make it easy to compare boulderers and bouldering sites. 

How Are Boulder Difficulties Rated?

Boulder problems are rated exclusively on how physically hard the problem is. These grades don’t consider any other variables like mental obstructions, the chances of injury, among others.

There’s no ideal formula for deciding the correct grade for the difficulty levels. While some people have suggested relying more on a particular formula, it’s still extremely subjective. 

For this reason, boulderers have argued and, most of the time, disagreed, and they still disagree about these grades till today. So, if you find these grades a bit confusing, you’re not the only one. 

Outdoors 

Outdoor bouldering difficulties have the advantage of being consistent. Therefore, in theory, most people can tackle a bouldering problem and determine its grade. 

On the other hand, it’s not very common for boulderer’s opinions to be considered when rating an outdoor problem. 

Honestly, the first person to try out the problem is the one who gives it a rating. Nevertheless, after several more attempts, the rating might be modified marginally. 

Ultimately, a grade is determined by the people who’ve climbed the difficulty or the local climbers. An individual adds the difficulty to Mountain Project, or people find out about it being a certain grade. After this, the grade is practically set. 

This is then followed by publishing a guidebook or updating the existent guidebook on this grade. But the author can consult the best climbers to see what they think on this rating and then publish it. 

What Is the Equipment Needed for Bouldering

Font Scale and V scale 

These are the two most common bouldering ratings used currently. While there are many bouldering rate scales, the most common ones are the Font and V scales. 

Here’s What You Need to Know about Each Bouldering Grade

V scale 

This is a flexible rating scale. Alternatively, the highest level of difficulty will increase as sport advances. It begins at V0 and presently ends at V17. 

Additionally, there is a level known as VB. This is the level that is most suitable for beginners. The B stands for beginner or basic, and this problem is more effortless than the V0. 

Oftentimes, the outdoor problems are graded “V-weird” or “V-Fun.” Typically, these are levels that resist the usual rating standards and require some odd climbing techniques. 

The V Scale has a simple perception; the higher the figure, the more challenging the level. Today, the most difficult bouldering problems are graded at V16 & V17.

Only a few people on earth can climb them. On the other hand, in gyms, you normally see the highest problem is at V10.

Furthermore, some charts include V, with a “+” or “- “to differentiate the complexity of the problem. For instance, V2+ is more difficult than V2 while V2 is more challenging than V2.

These postfixes are usually more common on the lower end of the scale, so it is rare to see them on the V10 or V11 levels. 

Every rating is by itself a level of sophistication. For instance, there are challenging V7s and “soft” V7s. How does this happen? 

This mostly occurs because the V7 might be more difficult than the V7s, though it might not be equally challenging as the V8 rate. 

Most of the recent debates around bouldering rates of the most difficult boulder levels concentrate on whether plenty of problems are V16s or challenging V15s. 

History 

V stands for “Vermin,” which is the Alias of John Sherman, a renowned boulderer who also invented the V scale. This scale was launched in Texas, in the late 1980s, by John and his bouldering friends. 

He gave a manuscript for his bouldering guide with multiple problems which were not rated. Since the problems were not rated, this manuscript was not published. 

After he graded the problems, the V scale guide was used in North & South America, Oceania, and SE Asia. 

Spotting for Bouldering

Font scale 

Also known as Fontainebleau Scale, the Font scale is open-ended like the V scale. It begins at one and advances from there. Nonetheless, problems with ratings easier than three are seldom heard of. 

Besides, like the V scale, the higher the figure in the Font scale, the more challenging the bouldering level. However, contrary to the V scale, when the font scale reaches 6, the scale incorporates specific suffixes to the figure to show changes in complexity. 

Typically, they integrate the A, B, and C suffixes. This means that the further the letter in the alphabet, the harder the climb. For example, 5C is more difficult than 5B, which is more challenging than 5A. 

Moreover, the scale includes a “+,” which is integrated after the letter, specifying another adjustment, which is not significant enough to change the whole letter or rating. 

The plus simply indicates that the level is slightly more difficult than the letter-number combination minus the plus sign. 

History 

This scale is more common in Asia and Europe, and it was launched sometime before the V scale. It was instigated in France in Fontainebleau Forest, thus the name. 

On the lower ratings, one V rating typically means wider than one rating on the font scale. On the other hand, at higher ratings, these scales are almost the same. For instance, a V16 problem is the same as an 8C+ problem.

Here’s a Basic Idea of Comparison between the Two Grading Systems

Novice: V0-V2/4.5+

This level is for beginners, whether completely new or with a bit of experience. Here, you’re still mastering the basics and advancing swiftly. 

Medium-level: V3 to V5/6A to 6C+

These grades are most suitable for a boulderer who’s been doing it for a while and is stronger now. This means that you can tackle problems that you couldn’t in the beginning. 

Advanced-level: V6 to V8/7A to 7B

These levels are for people who’ve been bouldering for several years. However, your initial fast advancing rate has decelerated marginally. 

How to Train for Bouldering Climb

Professional: V9 to V12/7B+ to 8A+

This level is for you who have been bouldering hard for numerous years. You can maneuver intermediate and advanced levels problems effortlessly. 

Elite: Over V13/8B 

You cannot go a long time without bouldering as it is part of your life. Perhaps, you’re even sponsored and in good shape. 

B Scale 

History 

Contrary to the Font and V scales, the B scale is fixed. When the scale was being designed, a B1 had the same moves as the hardest roped climbs. On the other hand, B2 was vague since it was only described as a bit challenging than B1. 

B3 was a level that had only ever been tackled once. Every time someone tackled a problem more than once, it was immediately downrated to B2. 

After this mechanism, John Gill designed the ratings to increase with complexity as the sport advanced. 

Nevertheless, the B scale is not that popular since it needs problems to be re-rated continuously, therefore, making comparison hard. 

The B scale was the original bouldering scale in the USA. It was invented by John Gill in 1958, and it only features the three ratings. 

Conclusion

So, there it is, bouldering grades and everything you need to know about them. Nonetheless, don’t focus too much on the numbers. 

Go to the gym or outdoors, have fun and continue progressing in terms of skills!
