Bouldering Grades: The Ultimate Guide

Navigating the world of bouldering grades can be a perplexing endeavor, whether you’re a bouldering novice or a seasoned climber. The numerical and alphanumeric codes assigned to boulder problems, referred to as bouldering grades, may leave you scratching your head.

Fear not, as we delve into the intricacies of this grading system to shed light on the subject.

Understanding Bouldering Grades

Bouldering grades stand as a universal metric, offering climbers a standardized means to assess the difficulty of boulder problems, whether encountered outdoors in natural landscapes or within the controlled environments of climbing gyms.

In outdoor settings, two prominent grading scales, the V Scale and Font Scale, take center stage. Each scale brings its distinctive attributes, contributing to the nuanced understanding of difficulty associated with boulder problems amid natural rock formations.

Indoor climbing gyms embrace the practice of grading, employing familiar systems such as the V Scale, Font Scale, or even creating bespoke rating structures. This diversity allows gyms to tailor difficulty assessments to their unique community and create an inclusive environment where climbers can progressively challenge themselves.

Why Grade Boulder Problems?

The establishment of bouldering grades stems from a fundamental need to provide climbers with a transparent and standardized measure of a problem’s difficulty. This grading system is a crucial tool that not only assists climbers in comprehending the challenges posed by a specific route but also empowers them to make informed decisions about the climbs they choose to undertake.

Bouldering grades serve as an essential guide, allowing climbers to gauge the suitability of a problem for their skill level. With a clear understanding of the grading system, climbers can navigate a spectrum of climbs, from those well within their capabilities to more challenging endeavors that push their limits. This nuanced approach to difficulty assessment encourages climbers to embark on a progressive journey of skill development.

Furthermore, bouldering grades foster a sense of cohesion and understanding within the climbing community. By providing a standardized language for expressing difficulty levels, grades enable climbers to share their experiences, achievements, and challenges with one another. This common vocabulary transcends geographical boundaries, fostering a global community where climbers can discuss, compare, and appreciate the unique characteristics of various bouldering locations.

In essence, the concept of bouldering grades goes beyond mere numerical assignments; it becomes a shared language that unites climbers, enhances safety by guiding climbers to appropriate challenges, and encourages a collective celebration of the diverse and dynamic world of bouldering.

How Do Boulders Get Graded?

The grading of boulder problems is intricately tied to their physical difficulty, considering various conditions that can influence the perceived challenge.

Boulder Grading Considerations

The list of conditions that are taken into consideration when grading a boulder can be the folowing:

• Environmental Factors

• Beta and Techniques

• Morphological Considerations

• Exclusion of External Factors

• Grade Range Considerations

Environmental Factors

Climbing conditions play a pivotal role so the asssigned grade is given when those conditions are optimal. For instance, a problem relying on friction and slopers may feel more challenging when climbed in the sun during summer than in winter with a refreshing breeze. The environment’s impact on holds and surfaces affects the overall difficulty.

Beta and Techniques

The assigned grade is contingent on utilizing the most effective beta or climbing techniques. If a climber does not employ optimal beta, the problem might seem more difficult than its assigned grade suggests. The grade assumes the application of the most efficient climbing strategies.

Morphological Considerations

The ideal morphology for a particular climb is considered during grading. If a move is favorable for taller climbers, the grade reflects the difficulty for individuals with that height advantage. Conversely, the same problem may feel more challenging for shorter climbers. Morphological aspects are a crucial factor in determining the assigned grade.

Exclusion of External Factors

Notably, grading focuses solely on physical difficulty and intentionally excludes factors such as the height of the boulder, potential injury risks, or mental challenges. The grading system isolates the physical demands of the climb from other variables.

Grade Range Considerations

Due to the inherent complexity of grading certain lines, grades are occasionally assigned within a range rather than a specific value. This flexibility acknowledges the nuanced nature of climbing difficulty.

The climbing community recognizes the inherent subjectivity in grading, leading to ongoing debates. It is crucial to understand that the grade serves as an indicator rather than an inflexible rule. Climbers should approach grades with a degree of flexibility and interpret them as guides rather than absolute benchmarks.

Indoor Grading Process

Indoor bouldering presents a unique grading landscape where the challenges are intricately woven into the fabric of artificial climbs. Unlike outdoor bouldering, the difficulties are primarily assessed based on the movements, the wall’s angle, and the climb’s length.

The controlled environment of indoor climbing facilities contributes to a softer grading experience. Several factors contribute to this discrepancy. First and foremost, the indoor routes are often color-coded, providing climbers with visual cues that outdoor climbs lack. This simplifies route reading and potentially reduces the overall skill required. Additionally, climbing gyms may adopt a strategy of incentivizing climbers by offering the satisfaction of conquering progressively challenging ascents, ultimately encouraging continued engagement with the sport.

Indoor bouldering problems are meticulously crafted by route setters, individuals dedicated to designing and testing new challenges for climbers. The grading process in indoor settings revolves around the route setter’s personal attempts, their nuanced understanding of the climb’s difficulty, and their accumulated experience with boulders of comparable grades.

Outdoor Grading Process

Outdoor bouldering introduces a dynamic realm of challenges, distinct from the controlled environment of indoor climbing. The difficulty in reading natural rock features, coupled with the often irregular and unpredictable terrain, amplifies the physical and mental demands of outdoor climbs.

Outdoor bouldering problems undergo a more dynamic evaluation. Following the initial ascent, the climber completing the first successful climb assigns a grade. Subsequent ascents and feedback from local climbers contribute to refining the grade, eventually reaching a consensus within the climbing community. Guidebooks play a significant role in documenting and disseminating these agreed-upon grades, providing a reference for climbers exploring outdoor locations. The static nature of outdoor problems allows for a collective evaluation over time, resulting in a more established and agreed-upon grading system.

Nalle Hukkataival’s Reflections on Elite Bouldering Grades

In a retrospective look at the outdoor elite bouldering world, Nalle Hukkataival shared his insights on the grading landscape, with a focus on developments around 8C (V15) climbs. Writing in 2010, Hukkataival traced the origins of the 8C grade to Fred Nicole’s ascent of Dreamtime in 2000. He noted a subsequent trend of deflation in the grading scale, with problems like Dreamtime and New Base Line undergoing downgrades.

Hukkataival, a key figure in the climbing community, attributed the media’s influence and the diminishing novelty of 8C ascents to potential overgrading. Drawing on personal experiences, such as his climb Livin’ Large in South Africa, he questioned the habitual tendency to initially overgrade problems and later await downgrades.

Expressing concern about the chaotic state of the upper grading scale, Hukkataival advocated for setting new standards that could withstand scrutiny, even if it led to numerous downgrades. He emphasized the need for open discussions on grading, acknowledging the personal nature of grades and the challenges in critiquing fellow climbers.

Writing with a voice rooted in the past, Hukkataival concluded by underscoring grades as estimates, subjective opinions that shaped perceptions and influenced climbing standards. He encouraged the climbing community to approach grading with responsibility and transparency, providing valuable insights into the ongoing debates around bouldering grades in the early 2010s.

V Scale & Font Scale: Two Prominent Grading Systems

Bouldering, unlike sport climbing with its myriad grading systems, simplifies things with two main grading scales – the V Scale and Font Scale. While there are other scales like the B-Scale, P-Scale, Joshua Tree Scale, and others, they don’t command the same prominence.

The Bouldering V Scale (a.k.a the Vermin Scale)

Developed by American bouldering legend John Sherman, affectionately known as “The Verm,” the V Scale categorizes problems into distinct difficulty levels, offering a standardized framework appreciated globally.

Sherman’s journey led him to create the V Scale out of necessity while conquering Hueco Tanks, Texas, where he amassed over four hundred first ascents—all without the protective cushion of crash pads. Despite speculation about its origin, the V Scale has become widely accepted and used across diverse climbing communities.

The V Scale spans from Beginner (V0-V3) to Elite (V17). An occasional + or – refines difficulty, making distinctions like V6+ slightly more challenging than V6. For absolute novices, the scale introduces VB (V-Basic), representing the most rudimentary climbs.

Beginner (V0 – V2)

A nice and straight-forward climb on good crimpy holds with a safe top-out and good landing.

Intermediate (V3 – V6):

A V6 with technical moves and intricate sequences, requiring a good understanding of body positioning.

Advanced (V7 – V9)

A classic V8 highball, is an iconic boulder problem situated in the Camp 4 area of Yosemite Valley. This historic climb, first ascended by Ron Kauk, presents a challenging mix of technical moves and powerful cruxes on the striking lightning bolt-shaped crack. The climb has become legendary in the bouldering world and attracts climbers seeking a unique challenge in a breathtaking natural setting.

Expert (V10 – V13)

A V12 renowned for its sustained difficulty, requiring precise footwork, finger strength, and body tension.

Elite (V14 – V17)

Jade is a challenging V14 boulder problem, situated in the stunning Rocky Mountain National Park in Colorado. First climbed by Daniel Woods, Jade is known for its demanding razor-sharp crimps and dynamic moves, showcasing a high level of skill and strength.

The Bouldering Font Scale (a.k.a the Fontainebleau Scale)

Similar to the V Scale, the Font Scale is open-ended, starting from 1 and progressing upward. As the scale reaches 6, it introduces letters (A, B, C) and “+” to denote incremental difficulty changes. For example, 6C is harder than 6B, and a 6A+ is more challenging than a 6A.

The Font Scale uses uppercase letters for bouldering difficulty levels, setting it apart from the lowercase conventions often found in the sport climbing grading system.

The Font Scale originated in Fontainebleau, France, “decades” before the establishment of the V Scale in the United States. Rooted in the magical bouldering forest, it has evolved into the preferred grading system for bouldering enthusiasts across continents, providing a standardized measure of difficulty in the natural beauty of Fontainebleau.

Beginner (3 – 5C)

An inviting beginner 3 climb featuring approachable holds and an enjoyable ascent

Intermediate (6A – 7A):

La Marie Rose, a 6B boulder problem, introduces climbers to more intricate sequences and technical moves, marking the transition to intermediate challenges.

Advanced (7A+ – 7C)

A classic Magic Wood problem featuring flat crimps on a pronounced overhang.

Expert (7C+ – 8B)

The Alphane Moon is world class boulder that demands a high level of finger strength, precise footwork, and strategic problem-solving. The low start is the famous Alphane 9A,

Elite (8B+ – 9A)

First climbed by Fred Nicole, Dreamtime presents climbers with a formidable combination of powerful moves, delicate holds, and precise foot placements.

Other Bouldering Scales

The Bouldeirng Kyū/Dan (段級) Scale (a.k.a. Dankyū or Soroban Scale)

In the heart of Japan’s climbing culture lies the Kyū/Dan (段級), a distinctive bouldering scale deeply rooted in tradition and precision. Commonly referred to as the Dankyū or Soroban, this approach draws inspiration from the hierarchical rank system employed in martial arts.

The Kyū/Dan system is divided into two halves: Kyū (級) and Dan (段). The Kyū scale initiates with 1-kyū, representing the introductory difficulty level, and progresses in ease as the numerical value increases. Noteworthy climbs such as Captain Ahab in Ogawayama and Ninjagaeshi in Mitake are graded as 1-kyū, exemplifying the starting point for climbers entering the Japanese bouldering scene. While there is technically no lower limit on the Kyū scale, 10-kyū is generally acknowledged as the easiest level within this classification.

On the other hand, the Dan scale commences with 1-dan, positioned as the level above 1-kyū. This level, akin to V7 to V8 or 7A+ to 7B, marks a significant step up in difficulty. Reaching the coveted 1-dan or Shodan (初段) level is equivalent to achieving a black belt in martial arts, signifying a climber’s prowess and mastery of the sport. The Dan scale extends indefinitely, capturing the intricacies of high-level climbs such as The Wheel of Life, rated at an impressive 6-dan–V16 or 8c+.

The Bloc scale

This grading scale, known as the “bloc” system, is used in Annot for bouldering, where each grade is denoted by a “B” followed by a number indicating the difficulty level. For instance, B1 represents “bloc level 1” and B12 indicates “bloc level 12.” This system is similar to the one employed in the new Peak District guidebook in England, and it aims to avoid confusion with sport climbing grades, which can be perplexing for those unfamiliar with the distinctions between bouldering and sport climbing grades using the Font Scale.

To maintain consistency within the site, the grading system in Annot is standardized based on reference problems for each grade. Some of these benchmark problems include:

• B4: Les trous du menhir
• B6: Madness
• B8: Blairwitch
• B10: Geebees
• B12: En avoir ou pas
• B14: Place des Cardeurs

Given the differences in style and the heterogeneity between various bouldering areas, the Annot grading scale does not propose equivalences with traditional grading systems, which varies significantly across locations like Fontainebleau, Ailefroide and Targassonne, However, to give a rough idea, a B6 in Annot roughly corresponds to a 6B in Fontainebleau. The hardest problem in Annot is graded B14 which roughly corresponds to a 8A.

This grading approach might initially frustrate climbers who focus primarily on grades, but it is hoped that after a brief period of adaptation, most climbers will appreciate the clarity and consistency it brings.

Bouldering Grades Conversion

Understanding the diverse grading systems in bouldering requires a reliable grade conversion table. This is especially crucial at lower grades where nuances in grading philosophies and local climbing cultures can lead to variations.

As climbers progress to higher grades, the alignment between the V Scale and Font Scale becomes more consistent, reflecting the standardized grading approach for advanced boulder problems.

The conversion table not only helps bridge these grading differences but also provides a structured framework for climbers to categorize their skill levels, set goals, and track progression across various systems.

Global Bouldering Grade Practices

Global bouldering communities exhibit a distinct preference for grading systems based on their geographical location. In North America, South America, Southeast Asia, and Oceania, climbers commonly adhere to the V Scale for grading boulder problems. Meanwhile, Europe and certain regions in Asia lean towards the Font Scale as their grading standard. This geographical correlation in grading practices reflects the historical development of climbing communities. It underscores the importance for climbers to familiarize themselves with both the V Scale and Font Scale, depending on their intended climbing destinations, fostering a more inclusive and interconnected global bouldering community.

In the following map you can see the Scale adoption by country.

Bouldering vs. Sport Climbing Grades

Bouldering and sport climbing, popular disciplines within rock climbing, each possess distinct challenges reflected in their grading scales. Understanding the nuances between these grades is crucial for seamless transitions between disciplines.

In bouldering, the V Scale denotes difficulty, starting with V0 for entry-level climbs. Sport climbing grades, represented by the Yosemite Decimal System (YDS), like 5.10d, indicate difficulty levels. Attempts to directly compare these scales may be challenging due to the different nature of challenges in each discipline.

The grading disparity stems from the unique demands of bouldering, emphasizing powerful bursts of strength, and sport climbing, requiring sustained endurance and route-reading skills. The psychological aspect varies, with bouldering demanding intense efforts, while sport climbing needs enduring mental focus. Though broad equivalences exist, the subjective nature of grading and diverse demands of each discipline make direct translation challenging. Climbers navigating both realms find value in recognizing and embracing distinct grading languages, treating each as a unique journey. The divergence in grading scales highlights the multifaceted nature of rock climbing, offering diverse experiences to explore and conquer.
