If you’re wondering how 8A+ converts to the V Scale or the Yosemite Decimal System, the short answer is: a Font 8A+ boulder is about V12, and a French sport 8a+ route is roughly 5.13c.
Climbing magazine lists Font 8A+ problems as V12. On the UIAA’s grade comparison table, a sport 8a+ falls at 5.13c. Lowercase 8a+ (sport) and uppercase 8A+ (Font boulder) are different scales, so any comparison of a sport 8a+ with a V grade is only a rough rule of thumb.
In this post, you’ll see how these grading systems compare, why they can be tricky to convert, and what to consider if you’re climbing across different systems.
Key Takeaways
- The French 8a+ grade represents a high level on the sport climbing difficulty scale. Climbers need to demonstrate exceptional strength, technique and endurance to complete these ascents.
- The V-scale is used to rate bouldering problems in the United States, starting at V0. A Font 8A+ boulder usually equates to V12.
- Converting between the French and V-scales is not straightforward. Differences in climb length, style, and grading philosophies further complicate matters.
- Both sport climbing and bouldering use unique grading systems tailored to their specific challenges, so understanding each system helps climbers set clearer goals and track progress.
- Climbing grades are highly subjective and notoriously inconsistent. Considerations such as route setting, individual ability, and community consensus are extremely important, so it’s important to be agile and careful in interpreting them.
- When you pay attention to the experience and individual journey of a climb, you really set yourself up for bigger impact. Adopting this approach will lead to a greater sense of fulfillment in your climbing experience.
Converting 8a+ to V-Scale Directly
If you hear people discussing climbing grades, the Font (Fontainebleau) system and the V scale are probably two of the first grading systems you’ll learn about. Both are equally popular, but connecting the two is not as easy as it seems. For climbers moving between Europe and the US, knowing how Font 8A+ lines up with the V scale helps set real goals and track progress.
The 8A+ in Font is frequently compared to V12 on the V scale. Most charts agree on this match, although some climbers feel 8A+ can be a little harder than V12. Yet it’s a narrow margin, and either grade leaves you power climbing at an elite level.
Here’s a quick look to make it clear:
| Font Grade | V Scale Equivalent |
|---|---|
| 8A | V11 |
| 8A+ | V12 |
| 8B | V13 |
The easiest way to convert a grade is to use the consensus grade for established climbs. Climbers consult guidebooks, online databases and speak with friends and others who have been on the routes. There’s no standard math, much of it comes down to gut instinct and feedback from the community.
Yet, all is not quite copacetic. The experience of grades is very different based on aesthetics, context, or even stature. An 8A+ boulder in France might convert to V12 in the States. The challenge isn’t inherently harder or easier, it’s all up to the climber.
Benchmark problems vary by area, so check local guidebooks for test pieces at the grade.
What’s the French 8a+ Grade?
The French 8a+ grade is a widely recognized marker of highly advanced skill in sport climbing. In the French grading system, the grades range from 1 (lowest) to 9c (currently the highest). Each grade is further broken down into sub-categories, such as “a,” “b,” or “c,” and often even an “+” for added precision.
The 8a+ grade sits high on that scale. It takes power and precision, but most of all it takes calculated actions to master the challenging ascent. For reference, a Font 8A+ boulder roughly corresponds to V12 on the Hueco “V” scale. On the Yosemite Decimal System, which is more widely used in North America, a sport 8a+ corresponds approximately with 5.13c.
These conversions aren’t terribly exact, but they do give an important context for climbers. They give climbers a sense of how a given route stacks up around the world.
Once at the 8a+ grade, climbers are usually in a world of steep limestone walls, micro holds, and extremely hard moves. Obviously power is important, but being mentally acute and maintaining form under fatigue is just as crucial.
To send an 8a+, even the best climbers spend years developing tendon strength, core tension, and precise foot placement. It’s easy to misinterpret this grade as a personal progression milestone. You’ll be able to find routes at this grade in any well-known climbing destination.
Climb the limestone crags of France or ascend the steep US boulders! The “+” in 8a+ means that the route is at the upper end of the 8a spectrum. It’s not quite at 8b grade just yet.
First, climbing grades are merely a consensus opinion among climbers. As more climbers try a route, what one group might have ranked as 8a+ can shift a bit. Within the greater climbing world, 8a+ is pretty damn impressive.
Still, it is a level that most climbers don’t reach, and many consider it an indication of extreme prowess. It often becomes a testpiece for elite climbers.
Decoding Bouldering’s V-Scale
Today, the V-scale is the predominant grading system for bouldering in North America. Climbers benefit by being able to quickly gauge the challenge of a climb with a simple digit. Occasionally, a + or – sign provides additional specificity to that rating.
This scale was codified by John “Vermin” Sherman for his 1991 guidebook to Hueco Tanks, Texas. The bouldering scale begins at V0, an excellent option for novices. For years it topped out at V17 (Font 9A), and the first V18 was proposed in 2025.
This is somewhat arbitrary because there is no defined upper bound, but as new, harder climbs are established the maximum grade increases. Adding a plus or minus, like V7- or V7+, lets climbers know if a route is on the easy or hard end of that grade.
The French scale is the standard for sport climbing in Europe. The V-scale, which was created solely for bouldering, offers a cleanly linear grade. For instance, a V11 on the V-scale would roughly equal an 8A on the Font scale.
The V-scale’s spectrum is expansive. V0 to V2 includes beginner climbs, appropriate for those just starting bouldering or honing fundamentals. V14 to V17 pushes the limits for elite climbers. These moves require extreme power and technical mastery, not to mention years of practice.
Climbers arrive at a grade by consensus, so the opinion of a lot of folks informs that final digit. The V-scale’s clear, step-by-step system helps everyone, beginners and experts alike, find climbs that match their level and track progress in the gym or outdoors.
Sport vs. Boulder: Why Scales Differ
Even though sport climbing and bouldering both involve climbing up walls, the two disciplines involve very different techniques. Consequently, their grading scales differ in order to represent these distinct requirements placed on climbers.
Sport climbing involves long, sustained routes, typically protected with bolts, that push an individual’s endurance to the limit. Bouldering is all about explosive, short moves that keep you fairly close to the ground. Instead, it focuses on power and short periods of agility.
The French scale is built for sport routes. On the other hand, the V-Scale, from V0 up, is exclusive to bouldering.
The character of each climb dictates the grading. Sport climbs often go higher, require rope protection, and require endurance and strategy along a longer climb. In reality, grading here is more of a sum of the parts type situation.
For boulders, it’s all about the hard, technical moves crammed into a small area. Bouldering problems tend to be more highly focused and singular. Because a single move can decide the grade, boulder grades often spark spirited arguments.
Another factor in grade perception is climbing style. A climber with calloused digits could breeze through V5 boulders and be “happier” than a 7a sport route that requires fluid motions.
Additionally, local climbing culture and what kind of rock is in play makes a difference. For instance, a Font 6B can feel quite a bit different from a typical V4 in the US. The outdoor grades are based on the community’s consensus.
They change over time as more climbers attempt the route and provide their own feedback. To train intelligently, climbers need to align their training with their objectives.
Sport climbers are looking to get in longer sessions for endurance, and boulderers are concentrating more on strength and solving short, hard moves.
The Subjectivity of Climbing Grades
Climbing grades are important for climbers to understand difficulty and use as a tool for comparing climbs and setting goals, but grades aren’t absolute. The first climber’s take is the beginning of the process of grading, but only the beginning. As each climber ascends a route, their feedback determines the consensus grade. As a result, grades tend to be more collaborative than dogmatic.
A route might feel easy to one person and tough to another, often due to differences in height, reach, style, or even weather on the day of the climb. Even route setters, who aim to provide equitable grades, can be biased. Grades can sometimes be revised as more climbers weigh in, further indicating how fluid and subjective this system is.
In outdoor climbing, this consensus is sometimes further subject to change by location. To illustrate, an 8a+ in California might be much easier or harder, depending on where you’re at in Colorado or even over in Europe. The introduction of letters and symbols, such as 7a+ or V5-, provide specificity yet open the door to further argument.
Various different systems, such as the Yosemite Decimal System and French Scale, are no exception to this oddity. Some are considered soft or hard, depending on the part of the country or gym. Bouldering’s V-scale, popularized in the early 1990s, was an attempt to delineate a more precise way of communicating small increments of difficulty.
Even that is pretty biased. Grades can be adjusted as more climbers go up the route and provide their opinions. This is a testament to a sport that is ever-changing, ever-learning, and responsive to its community.
Beyond the Numbers: Climbing Feel
In contrast, climbing grades like 8a+ or V-scale set unified standards for judging difficulty of routes. Those numbers can only tell us so much about the experience as a whole. The authentic climbing experience is far more than about grades.
How a climb feels, the flow of moves, the position of the body, the mental challenge it requires, determines the overall experience. Grades are mostly subjective and based on the opinions of a small number of climbers. They take into account steepness, hold size, how hard the moves are in comparison with other climbs.
When it comes to the feel of a route, it’s an individual thing. One climber sails up a delicate face with crimp holds due to their superior finger strength. Another climber may struggle on the same face and call the route “sandbagged.”
Vandalism, weather, and heavy repeated use can all significantly change the rock. This alteration can make for better or worse holds, making even an old route feel new and different after a while.
Route style plays a significant role as well. A slab in Bishop with tiny edges offers a memorable and challenging climb. It’s an entirely different feel compared to the steep roofs at Hueco Tanks, despite the fact that they might be the same grade.
Geological features such as cracks and arêtes provide distinct climbing experiences. An individual who is used to climbing in a gym can be surprised by the things that outdoor routes have to offer.
Mental factors weigh heavily too. If you’re afraid of falling or the sequences are just particularly tricky that day, a route may feel way above your number, regardless of the rating. Gradually, as climbers experience more rock and years, they stop being so concerned with climbing for the sake of grades.
They see the improvement themselves, caring less about what’s hard and what’s easy and more about developing the movement and relishing the puzzle. Climb as much as possible in order to truly get behind the feel of climbing.
Try out new approaches and learn from your peers to find what works for you.
Applying Conversions at the Crag
Converting on-the-fly at the crag is more than just referencing a conversion chart. With routes tagged by French, American, or Australian grades, sometimes more than one, the task gets tricky fast. Climbers are frequently left to believe that the official grade is subject to vary based on what system any given guidebook or local climbing community supports.
A Yosemite Decimal System rating of 5.8 might translate to an Australian Ewbank rating of 15 or 16. This analogical comparison shifts according to the climbing context. Local grades usually come first. It pays off to double check how each place grades or describes their grades.
Here are some quick tips for handling grade conversions out in the field:
- Get a read on grades from local climbers as their perspectives help inform what’s “normal” at a crag.
- Refer to the local guidebook to get a sense of the grade context. Local signage can further help instruct users which system to rely on first.
- Approach with an understanding that grades are often a range (for example, 7a/7a+), and can change following community input.
When you finish a climb, take a minute to write in your notebook how the grade felt, how hard it was. This helps you more accurately gauge what a climb will be like relative to your personal grade. If different sources list different grades for a route, take note and verify before you jump into the climb.
Perhaps the greatest lesson of all though, is that flexibility is key. Subjectivity of grades become magnified, influenced by local culture and the vast possible ranges each grade label could span. By encouraging climbers to record their own trip data, we can empower them to make better decisions on their next visit.
My Take: 8a+ vs. V12 Experience
Climbing an 8a+ route and a V12 bouldering problem both stand as benchmarks for advanced climbers in the US and Europe. While the shared name with Font 8A+ (V12) can make them seem the same on paper, both representing a very high level of challenge, the style and experience that comes with them can be night and day.
The issue becomes one of long-term power sustainability on extended 8a+ routes. You don’t only need great body movement and quick footwork, you need to read the sequence and control the pump over 20+ moves. The key is maintaining rhythm, searching for pauses, and choosing a path wisely from the beginning to the end.
Unlike the V12 boulders, these come at you quickly. In this case, the issues are brief yet intense. You only have so many moves to work with, but each one can be a crux in its own right.
Especially when it comes to power moves, holding on requires raw strength, high body tension, and spot-on technique. You don’t have the luxury of getting it wrong or waiting to think again. Screw it up, and you’re back to square one, starting from scratch.
In all those ways, many climbers view V12 as a true level up, a grade that indicates you’ve transcended the blue belt realm of the intermediates. Getting to this point is a hallmark of having toiled for years, accumulated callouses, properly developed that muscle memory and mental clarity.
The most important aspect for both is the mental side. On cruxes, you confront the fear of failure and that joyful despair of a long campaign. On boulders, it’s more about composure and focus under fire and maintaining performance level through burn out on the project.
Maybe some climbers are intimidated by V12-style moves, other people like the long-term challenge of 8a+.
Climbing Grade Conversions
Frequently Asked Questions
What does 8a+ mean in climbing grades?
It indicates a very high degree of difficulty, often only achievable by the most experienced or professional climbers. This grade is predominately seen on outdoor sport climbing routes, particularly in Europe.
How does 8a+ convert to the V-scale?
As a Font boulder grade, 8A+ is approximately V12. A French sport 8a+ route is roughly 5.13c on the YDS. These are only estimates, as sport and boulder scales measure different types of climbs: endurance versus power.
Why are climbing grades like 8a+ and V12 different?
Sport climbing grades like 8a+ primarily take route endurance into account, whereas V-grades like V12 emphasize short, powerful moves. Since they represent different climbing styles, direct comparisons are not always ideal.
Is the 8a+ grade used in the United States?
Not usually. American climbers mostly use the Yosemite Decimal System (YDS) for sport routes and the V-scale for bouldering.
Are climbing grade conversions always accurate?
No. Elements such as route style, location, and even personal strengths affect how difficult a grade may seem. Avoid treating climbing grade conversions as an exact science.
What should I do if a converted grade feels too hard?
Don’t worry. Grades are deeply subjective. Focus on your own experience and climb consistently.
Why does the “feel” of a climb matter more than the grade?
While the grade provides a helpful point of reference, how you experience a climb is subjective. Weather, rock type, and your own strengths certainly come into play. Have fun with the experience, not just the figure.
