Guide to Bouldering Grades

Bouldering Grades

Bouldering is a form of rock climbing that is performed without the use of ropes or harnesses. The goal is to reach the top of a boulder problem or route. Bouldering grades are the assigned difficulty ratings to boulder problems. The two most common boulder grading systems are the V-Scale and the Fontainebleau Scale.

Bouldering Grade Systems

Bouldering grade systems are a means of comparing the difficulty of climbs. Different countries and organizations use different systems, so it is often useful to be familiar with more than one. The most popular systems in use today are the V-scale, the Fontainebleau system, and the Hueco scale.

The V-scale was originally developed by John Sherman in the early 1980s and has since been adopted as the standard grading system in the United States. It goes from V0 (the easiest) to V16 (the hardest). The Fontainebleau system is popular in France and uses a different set of grades, from 1A to 7C+. The Hueco scale is used mainly in North America and Mexico and ranges from HB (hard bouldering) to V9 (very hard).

In addition to these three main systems, there are also a number of others that are used in specific areas or for specific types of climbing. For example, the British use a Boulder Grade System that goes from 3a to 8a+, while the Japanese use a similar system that goes from 5-6A to 8B. There is no one right way to grade climbs, so it is important to be familiar with the system that is being used in your area.

Bouldering Grade Conversions

Bouldering grades are always a source of confusion for new climbers, and even experienced climbers can get stubbed toes when traveling and confronted with a completely different grading system. don’t sweat it; bouldering grades are more art than science, and the most important thing is that you’re enjoying yourself on the rock. Here is a quick bouldering grade conversion chart to help you get an idea of what you’re looking at when confronted with an unfamiliar system.

V Scale:
The V Scale goes from V0 to V17. Most gyms in the United States use this system. The hardest boulder problem in the world, Nosferatu (V16), was climbed by Adam Ondra in Czech Republic in 2009.

Fontainebleau Scale:
The Fontainebleau scale ranges from 1 to 7c+. This system is used mostly in Europe, particularly France, where the rocks of Fontainebleau give this system its name. Bleausards often use a plus or minus to further delineate the severity of climbs within each grade, so don’t be surprised if you see something like 7a+ or 6c-. Once you get above 7b, things start to get really serious; only a handful of climbers in the world have climbed problems graded 8A (V13) or above.

Hueco Tanks Scale:
The Hueco Tanks scale goes from V0 to V13+ and is used mostly in North America outside of the gym climbing world. The hardest boulder problem ever climbed in Hueco Tanks was named ‘Neighborhood Watch” (V13) by Paul Robinson and was first climbed by him in 2009.

Bouldering Grade Descriptions

Bouldering grades are essential for climbers to communicate the difficulty of a climb to others. The most popular bouldering grading system in North America is the V-Scale, however there are many regional variations. The V-Scale ranges from V0-V16, with V0 being the easiest and V16 being the hardest.


V0, otherwise known as a “very easy” climb, is usually considered the starting point for a boulderer. V0s are few and far between at most bouldering gyms, as they are meant to be an introduction to the sport and don’t require much technique or strength to complete. Don’t be intimidated by the grade — everyone started somewhere!

V1, or “easy”, is where most people begin to learn some of the basic techniques required for bouldering, such as using momentum to complete a move, or using different parts of your body to gain leverage. V1s will often have larger holds that are easier to grab onto, and the moves will be less physical than those on harder problems.

V2, or “intermediate”, is when things start to get really interesting. V2s require good technique and sometimes a bit of creativity to complete, and they often have small holds that can be difficult to grip. This grade is usually where people start to spend more time on a problem before moving on, as they can be quite challenging.

V3, or “difficult”, is the point at which most people start to feel like they’re in over their heads. V3s are often strenuous and require precise moves in order to be completed. This grade is not for the faint of heart — only attempt a V3 if you’re feeling confident in your abilities!

V4, or “very difficult”, is where things start to get serious. V4s are incredibly physically demanding, and often require perfect technique in order to succeed. This grade is not for beginners — make sure you’re physically and mentally prepared before attempting a V4!

V5, or “extremely difficult”, is the highest grade of boulder problem that most climbers will ever attempt. V5s are incredibly physically demanding and require perfect technique in order to succeed. This grade is not for beginners — make sure you’re physically and mentally prepared before attempting a V5!


V1, called a “sit start” in the Unified English Scale (UES) is considered the easiest possible grade. Boulderers typically use a bouldering mat to prevent injuries from falls.

Boulderers frequently encounter natural grading systems with multiple, concurrent Gradings. For example, in Australia one might find a problem graded as 8a in the Fontainebleau system and 24 in the Broken Circuit system. It is often useful to use more than one grading system when attempting bouldering problems, Josh Larson suggests using two different systems side-by-side such as the UIAA and Fontainebleau systems to gain a better understanding of the overall difficulty of a problem.


In bouldering, the V-scale is commonly used to rate the difficulty of problems. The grade is an open-ended numeric scale, with a predominant range of V0 to V16. The scale was originally created by Chuck Fryberger in the early 1980s, and has been modified slightly several times since then.

The hardest boulderproblem in the world is currently considered to be V17, or “Hubbard’s cupboard” in Rocky Mountain National Park, first climbed by Dave Graham in 2005.

Here is a brief description of each grade:

V0: Easy – A very easy problem that even a beginner should be able to complete.

V1: Moderate – A bit more difficult than V0, but still relatively easy.


In bouldering, the V-scale is used to rate the difficulty of problems. The scale goes from V0 to V17. The hardest boulder problem in the world is currently thought to be V16.

The V-scale was originally created by John Sherman in 1991 and has since been refined by other climbers. The scale is open-ended, which means that it can continue to be extended as climbers find new ways to challenge themselves.

Here are brief descriptions of each grade:

V0: Easy – A good place to start if you’re new to bouldering. These problems usually don’t require any advanced techniques and can be completed by most people with some effort.

V1: Moderate – Still relatively easy, but may require some simple moves that are new to you. You may also need to use your body in ways that feel unnatural at first.

V2: Hard – Starting to get difficult now. These problems will likely require multiple attempts before you can figure out the correct sequence of moves. You may need to be creative in your approach and use your strength and endurance as well as your technique.

V3: Very hard – Now we’re getting into the realm of true difficulty. These problems will test everything you’ve learned so far and push you outside of your comfort zone. Be prepared for some serious frustration before you finally reach the top!

V4: Extremely hard – You’ll need all of your skills just to stand a chance of completing these boulder problems. Expect multiple failures before you finally succeed, and don’t get discouraged if it takes days or even weeks to send one of these.

V5: Comparable to many sport routes – Now we’re getting into the territory of world-class climbers. These boulder problems are extremely challenging and should not be attempted without significant experience and preparation.333 33A dangerously difficult problem that requires exceptional skill and physical strength


V4 is considered a very hard boulder problem, and most climbers will spend quite some time power-endurance training to be able to do one. V4s tend to have multiple moves in a row that require similar strength, often with very few (if any) rest positions. Some common features of V4 boulder problems include: -overhangs -pockets -dynos (jumping for a hold) -efficient movement


V5 is the first grade where you will start to see people using dynamic moves off the ground. Routes at this grade will require some strength, and may also include small handholds, slopers, and Gaston holds. You will need to be able to control your body while making moves that are not always straightforward.


In the V grade system, V6 is considered fairly difficult. A boulderer who can consistently climb V6s is on his or her way to becoming an expert. Although each area has its own unique grading system, V6 generally falls into the following characteristics:

  • Heights of around 12 to 15 feet
  • Climbs that are slightly overhanging with small to medium sized holds
  • A few tricky sequences
  • Moves that require some core strength and power

V6 climbs may seem impossible at first, but with practice and experience, they will eventually become easier. boulder problems in this grade range are a great way to improve your technique and strength.


V7 is considered very difficult. A V7 boulder problem will likely have 2-4 moves of pure strength, and the rest of the moves require good technique. A successful ascent of a V7 will require several tries.


V8 is physical and committing. Routes at this grade will often have long moves between big holds, and require good endurance. boulder problems at this grade often feel like they take everything you have to complete.


V9 is considered very hard for the average climber. Routes at this grade will require creative sequences, powerful moves, and good endurance. V9 boulder problems usually take between 4 and 10 tries to complete.


In bouldering, the V0 grade is used to describe the easiest problems. V0s are usually only a few moves long and require little to no gymnastic ability. Juggy problems (ones with large, easy-to-hang onto holds) are often given a lower grade than slopers (problems with small, hard-to-hang onto holds).

As the grades get harder, they are split into subgrades: V1-, V1, V2-, etc. When a problem is on the cusp of two different grades, it is given both grades with a slash in between (e.g. V5/6). A problem that is significantly harder than any other problem in its grade is said to be an “open-project” and usually has a “+” after its grade (e.g. V10+).

Bouldering Grade Tips

Bouldering grades are designed to give climbers an approximate idea of the difficulty of a route. The two main bouldering grade systems in the United States are the V-Scale and the Fontainebleau Scale. The V-Scale is the most commonly used grading system for bouldering in America. The Fontainebleau Scale is used more frequently in Europe.

Bouldering Grade Tips for Beginners

Bouldering is a type of rock climbing that is performed without the use of ropes or harnesses. Instead, climbers rely on Crash Pads – thick, cushioned mats – to protect them from falls. Bouldering routes (or problems) are typically shorter than those in roped climbing, but they often require more physical strength and technical skill to complete.

Bouldering grades are used to indicate the difficulty of a particular route. In the United States, the most commonly used bouldering grade system is the V-Scale, which ranges from V0 (very easy) to V16 (nearly impossible). While some beginner climbers may be able to complete a V0 problem without too much trouble, it is extremely rare for anyone to send a V16.

Here are a few tips to help you get started with bouldering grades:

  • Start with easier problems: As a beginner climber, it is important to start with problems that are well within your ability level. You will likely be surprised at how quickly you improve and will soon be ready to tackle more difficult routes.
  • Don’t get discouraged: It is normal to feel frustrated when you’re first starting out. Remember that everyone climbs at their own pace and there is no shame in taking your time to progress through the grades.
  • Climb with friends: Bouldering can be more fun when it’s done with friends. Not only will they be able to offer support and encouragement, but they can also help spot you if you fall.

Bouldering Grade Tips for Intermediates

In bouldering, grade is everything—it will determine the number of attempts you make on a problem, how long you spend cursing at the wall, and whether or not you’ll be able to complete the boulder. Bouldering grades are classification systems that indicate the level of difficulty of a particular boulder problem or route. The two most common bouldering grading systems are the V-scale and the Fontainebleau system. In this article, we’ll focus on the V-scale since it’s more widely used in North America.

The V-scale ranges from V0 to V16 and was first proposed by John Sherman in 1991. The grades are intended to indicate the technical difficulty and physical strength required to complete a boulder problem or route. For example, a V0 would be considered easy—it would require basic moves and little strength. A V16, on the other hand, would be considered extremely difficult—it would require complex moves and a high level of physical strength.

As a general rule of thumb, Boulder Grades Difficulty increases by about two letter grades per every increase in height. So, for example, a taller Boulder that is graded V3 will be more difficult than a shorter one graded at V3. This rule is not always followed perfectly but it’s a good guideline to keep in mind.

If you’re just starting out, we recommend trying problems in the V0-V2 range. Once you’ve mastered those, move on to the V3-V5 range. And so on—work your way up gradually until you’re able to complete Boulder problems at the highest level.

Bouldering grade is important, but it’s not everything. Don’t get too caught up in achieving perfect send after perfect send—just have fun and enjoy yourself!

Bouldering Grade Tips for Experts

In bouldering, grade tips are very important because they act as guidelines to help climbers know what to expect when they attempt a route. The most common bouldering grading systems are the V-Scale and the Fontainebleau system. The V-Scale is used in the United States, while the Fontainebleau system is used in Europe.

Both of these grading systems use a numerical scale to indicate the difficulty of a route. The lower the number, the easier the route is. For example, a V0-graded route is going to be much easier than a V10-graded route.

If you’re an experienced boulderer, you likely already have a good understanding of how these grading systems work. However, it’s still helpful to know some specific grade tips that can help you when you’re trying to decide which routes to attempt.

Here are a few grade tips for experts:

  • If you’re climbing at your limit, don’t be afraid to back off and try an easier route. It’s better to get some successful climbs under your belt than to get frustrated and give up altogether.
  • Don’t let your ego get in the way of your climbing. Just because a route has a low grade doesn’t mean it’s going to be easy. Likewise, just because a route has a high grade doesn’t mean it’s going to be impossible.
  • Don’t judge a route solely based on its grade. There are many factors that can affect the difficulty of a climb, such as the length of the route, the type of holds, and the angle of the wall.
  • Remember that grades are only meant to be guidelines. They’re not set in stone, and they will vary from climber to climber based on factors like strength, experience, and technique.
