In this article, we will explore what the 90 degree rule is, how it affects your ascents, and why it’s important to understand this concept. Get ready to take your climbing skills to new heights with this informative guide on the 90 degree rule in climbing.
The 90 degree rule in climbing refers to the angle at which a climber must transition from one type of terrain to another. This rule is important because it can affect the difficulty and safety of a climb. For example, if a climber is ascending a slope that is steeper than 90 degrees, they may need to use different techniques or equipment to maintain their footing and avoid falling. On the other hand, if a climber is ascending a slope that is less than 90 degrees, they may be able to use more relaxed techniques and take longer breaks. In general, the 90 degree rule is an important consideration for climbers when planning their routes and choosing their gear.
Understanding the 90 Degree Rule in Climbing
Definition and Origin
The 90 degree rule in climbing is a fundamental principle that governs the ascent of a mountain or rock face. It is a rule of thumb that dictates the angle at which a climber should ascend a slope. This rule is based on the premise that the angle of the slope should not exceed 90 degrees, or a ratio of 1:1, between the slope and the horizontal plane.
The 90 degree rule is rooted in the physics of mountain climbing. When a climber ascends a slope that is steeper than 90 degrees, it becomes increasingly difficult to maintain their footing and balance. This is because the angle of the slope increases the force of gravity acting on the climber, making it harder to maintain their footing and balance. As a result, the climber must use more energy to maintain their position, which can lead to fatigue and increase the risk of falls.
In addition to the physical challenges of climbing steep slopes, the 90 degree rule also takes into account the potential for avalanches and other hazards associated with steep terrain. Climbing slopes that exceed 90 degrees can increase the risk of avalanches and other hazards, as the steep terrain can create unstable conditions that can lead to accidents.
Overall, the 90 degree rule is an important principle in climbing that helps climbers to safely and effectively ascend a mountain or rock face. By adhering to this rule, climbers can minimize the risk of accidents and increase their chances of a successful ascent.
Applications and Limitations
When to use the 90 degree rule
The 90 degree rule in climbing is a technique used by climbers to determine the most efficient path while ascending a route. This rule is applied when a climber is facing a series of angles, rather than a continuous slope. In such cases, the climber should aim to climb at an angle of approximately 90 degrees from the slope they are on. This rule helps climbers to minimize the amount of up-and-down climbing, thus reducing the overall distance and time required to reach the summit.
Situations where the 90 degree rule is not applicable
While the 90 degree rule is a useful tool for climbers, it is not applicable in all situations. For instance, when climbing a route with a consistent slope, the rule may not provide any advantage. In such cases, the climber should focus on finding the most efficient path, regardless of the angle. Additionally, the 90 degree rule should not be used when climbing a route with exposed sections or overhanging cliffs. In these situations, the focus should be on finding secure hand and footholds, rather than on achieving a specific angle.
Overall, the 90 degree rule is a useful technique for climbers to optimize their ascent, but it should be used in conjunction with other climbing techniques and tactics, and not in situations where it may not provide any advantage.
Climbing Techniques and Moves Involving the 90 Degree Rule
Essential Climbing Techniques
Jamming
Jamming is a technique used by climbers to maintain their hold on a climbing route. It involves inserting a hand or a foot into a crack in the rock and using the friction created by the placement to support the climber’s weight. The 90 degree rule is critical in jamming as it dictates the angle at which a climber can insert their hand or foot into a crack for it to be effective. The rule states that a climber should never place their hand or foot in a crack at an angle greater than 90 degrees from the vertical. This is because the friction created by the placement is directly proportional to the angle of the placement, and if the angle is greater than 90 degrees, the friction will be too low, and the climber will not be able to support their weight.
Jumaring
Jumaring is a technique used by climbers to ascend a rope quickly and efficiently. It involves clipping a climbing device, such as a Jumar, to the rope and pulling oneself up using the device. The 90 degree rule is critical in jumaring as it dictates the angle at which a climber can place their device on the rope for it to be effective. The rule states that a climber should never place their device on the rope at an angle greater than 90 degrees from the vertical. This is because the friction created by the placement is directly proportional to the angle of the placement, and if the angle is greater than 90 degrees, the friction will be too low, and the climber will not be able to ascend the rope efficiently.
It is important for climbers to understand the 90 degree rule and its implications on their climbing techniques. By adhering to this rule, climbers can ensure their safety and efficiency while climbing.
Advanced Climbing Techniques
When climbing, advanced techniques can make or break a climb. These techniques involve using the 90 degree rule to make challenging moves and progress up the route.
Heel hooking
Heel hooking is a technique where a climber uses their heel to hook onto a small edge or hold. This allows the climber to shift their weight and make difficult moves. It requires precise footwork and body positioning to execute successfully.
Off-width techniques
Off-width techniques involve using both feet and both hands to maintain a secure stance in a wider crack or seam. This technique requires careful footwork and body positioning to prevent slipping or losing control. Off-width techniques can be especially useful in situations where the crack is too wide for a traditional hand or foot hold, but not wide enough to accommodate a fist or two feet.
Common Mistakes to Avoid
Overuse of the 90 degree rule
One common mistake to avoid when climbing is the overuse of the 90 degree rule. While this technique can be useful in certain situations, relying too heavily on it can lead to a lack of progress and a feeling of being stuck in a particular position. Climbers should be mindful of when to use the 90 degree rule and when to try other techniques to avoid getting stuck in a rut.
Improper body positioning during climbs
Another mistake to avoid when climbing is improper body positioning. When using the 90 degree rule, it is important to maintain proper body positioning to ensure that the technique is effective and safe. Climbers should pay attention to their footwork, hand placements, and body positioning to ensure that they are in the most stable and secure position possible. Failure to do so can result in a loss of balance and control, which can lead to falls and injuries.
By avoiding these common mistakes, climbers can make the most of the 90 degree rule and use it effectively to make progress and achieve their climbing goals.
Impact of the 90 Degree Rule on Climbing Safety
Risks and Consequences
The 90 degree rule in climbing is a critical aspect of the sport that has a significant impact on safety. It is a rule that requires climbers to transition from one pitch to another at a 90-degree angle, rather than following the same line of ascent. This rule is designed to minimize the risk of rock fall and increase safety for climbers.
Injuries and accidents caused by the 90 degree rule
Despite its intentions, the 90 degree rule can also lead to injuries and accidents if not followed properly. Climbers who attempt to descend a route that is too steep or who fail to transition correctly can experience falls, slips, and other accidents. Additionally, the use of anchors and other climbing equipment can be hazardous if not properly secured or if the climber is not properly trained in their use.
Prevention measures
To prevent injuries and accidents caused by the 90 degree rule, climbers must take several prevention measures. First, climbers must be properly trained in the use of climbing equipment and techniques. This includes learning how to properly secure anchors and transition between pitches. Additionally, climbers should always assess the climbing route and conditions before starting the ascent, and use appropriate safety gear, such as helmets and harnesses.
Another important prevention measure is to always climb with a partner. Having a partner allows climbers to provide mutual support and assistance, as well as to watch each other’s backs and provide early warning of potential hazards. Finally, climbers should always have a plan for emergencies, such as knowing the location of nearby emergency services and carrying a first aid kit.
Overall, the 90 degree rule is an important aspect of climbing safety, but it must be followed properly to prevent injuries and accidents. Climbers must be properly trained, use appropriate safety gear, and always climb with a partner to minimize the risks associated with this rule.

The 90 Degree Rule in Different Climbing Disciplines
Sport Climbing
How the 90 degree rule affects sport climbing
In sport climbing, the 90 degree rule plays a crucial role in determining the difficulty of a climb. This rule states that the angle of the wall or cliff face is the primary factor in determining the difficulty of a climb. Specifically, the more vertical the wall, the more difficult the climb will be. This is because vertical walls require climbers to use their full range of technical skills, including precision footwork, body positioning, and rope management.
Popular climbing routes and grades
Some of the most popular climbing routes in sport climbing are those that adhere closely to the 90 degree rule. For example, the famous “Nose” route on Yosemite’s El Capitan is a Grade VI, 5.14a climb that follows a nearly vertical line up the face of the rock formation. Another popular route is the “Dawn Wall” on the same formation, which was the first route to be climbed using only natural holds and is considered one of the most difficult routes in the world. Both of these routes are graded at 5.14a, which is considered a very difficult climb for experienced climbers.
In addition to these well-known routes, there are many other sport climbing routes around the world that follow the 90 degree rule and present challenging climbs for experienced climbers. These routes are often found in areas with steep, vertical cliff faces, such as the Frankenjura region in Germany, the Red River Gorge in Kentucky, and the limestone cliffs of the Italian Dolomites. Climbers seeking to tackle these routes must have a high level of technical skill and experience, as well as a strong physical fitness and mental focus.
Traditional Climbing
Importance of the 90 degree rule in traditional climbing
In traditional climbing, the 90 degree rule is crucial as it determines the placement of protection and the path of ascent. Traditional climbing, often abbreviated as trad climbing, is a style of climbing in which climbers place their own protection as they climb, usually using nails or cams hammered into cracks in the rock. This protection is used to secure the climber in case of a fall, and the 90 degree rule is used to ensure that the protection is placed effectively.
Traditional climbing gear and equipment
Traditional climbing gear includes a variety of equipment, such as nuts, cams, and pitons, which are used to protect the climber in case of a fall. These pieces of equipment are placed in cracks in the rock, and the 90 degree rule dictates the optimal placement of this gear.
In trad climbing, the 90 degree rule states that protection should be placed no more than 90 degrees from the axis of the crack being protected. This rule is based on the assumption that the protection will be more effective if it is placed perpendicular to the force of a fall. If protection is placed too far from the axis of the crack, it may not provide enough support in the event of a fall.
Understanding and following the 90 degree rule is essential for climbers engaging in traditional climbing, as it helps to ensure their safety while climbing. By placing protection effectively, climbers can minimize the risk of falls and increase their chances of successful ascents.
Ice Climbing
Specific techniques and moves in ice climbing
Ice climbing is a unique and challenging discipline that requires specialized techniques and moves to ascend icy surfaces. One of the most important techniques in ice climbing is the use of ice screws, which are driven into the ice to provide a secure anchor point. Other techniques include using ice tools to chip and dig into the ice, as well as using crampons and ice climbing boots to provide stability and traction on the icy surface.
Gear and equipment for ice climbing
Ice climbing requires specific gear and equipment to ensure the safety and efficiency of the climber. This includes ice screws, ice tools, crampons, ice climbing boots, helmets, and warm clothing. It is important to choose the right gear for the conditions and to ensure that it is properly maintained and used. Additionally, climbers must be familiar with the proper techniques for using this gear and must practice using it before attempting to climb.
