When planning for a climb, one of your first consideration is likely to be the difficulty of the climb.
It is a tough thing to measure. But that did not stop climbers around the world from trying.
Unfortunately, these rating systems can cause a lot of confusion as well.
Many regions and countries use their own difficulty rating and grading systems. There are also different rating systems for different forms of climbing.
It can get pretty overwhelming very quickly.
I have been learning about these different systems for a few weeks now. These are the notes I have made which I hope will be useful for you as well.
In this guide, I will cover:
- 15 common types of climbing grades and rating systems
- The region or country are they used in
- The types of climbing are they used for
- The suitable climbing grades for a beginner
Before we start…
Types of Climbing
Climbing is a very broad term that includes many types of activities.
Read: What Is Non Technical Climbing?
Some of the rating systems in this article are used for a specific form of climbing.
- Rock climbing: this means using your hands and feet to climb up a vertical rock surface. May not include an ascent to the summit of a mountain.
- Ice climbing: this means using your hands and feet to climb up a vertical rock surface. May not include an ascent to the summit of a mountain.
- Mountaineering/ mountain climbing: climbing with the objective of reaching the summit of a mountain. May includes rock climbing, ice climbing, both or none (i.e. hiking or trekking).
- Alpine climbing: seen as the “tougher” form of mountaineering. Involves climbing to summits of high altitudes. Climbs are often in icy or snowy terrains and with a technical component.
Ratings are typically assigned to a specific trail or route and not for the entire mountain. One mountain can have multiple routes and trails with different ratings.
Beginner’s Guide
Climbing ratings are confusing even for experienced climbers. And it can sure be overwhelming for someone who is just starting out.
For each of the rating system, I have listed which grades or ratings that are suitable for beginners. Beginners should start off with non-technical climbing. This means ascending a mountain without the use of any specialized climbing equipment.
Consistency And Accuracy Of Rating Systems
A lot of effort has gone into creating and improving the various rating and classification systems. And yet, it remains more of an art than a science.
Even within a single rating system, climbs can be rated very differently.
After all, the difficulty of a climb will be very different between one individual and the next. Comparing a climb in different areas and between different mountains is also an uphill task (pun!).
There are many ways in which climbing rating and grades are typically assigned:
- Assigned by the first person or group to climb that mountain
- Assigned by the author of a guidebook or article
- Assigned by consensus among a group of climbers

1. Yosemite Decimal System (YDS)
| Usage | Used mainly in the United States and Canada. |
| Types of climbing | Used to rate: – Mountaineering/ mountain climbs – Rock climbs |
| Measures | – The difficulty of a climb (i.e. how difficult to ascend, descend or retreat). – The duration of a climb. – The exposure of a climb (i.e. how much protection there is). |
| Rating System | – Class Rating: Class 1 to 5 – Grade Rating: Grade I to VII – Protection Rating: G to X |
| Beginner’s guide | – Class 1 and 2 climbs are suitable for beginners. – Beginners can attempt Class 3 climbs with a guide. |

The YDS has a class rating and an optional grade and protection ratings.
The YDS originally consisted only of the class rating and this is the most widely used rating.
The grade and protection ratings were added on later to improve the rating system. But their usage remain low.
Here is an overview of the 2 rating categories:
- Class rating: To classify climbs into hikes, scrambles and rock climbs.
- Grade rating: To indicate the duration of a climb.
- Protection rating. To indicate the danger of a climb and the level of protection available for the leader of a climb. Poor protection is when the anchor points are very far apart from each other. Or when an anchor point is insufficient to prevent a climber from serious injuries during a fall.
Class Rating System
A class is assigned based on the most difficult part of the climb.
For instance, if a route is mostly a Class 1 walking trail with a short section of a Class 4 climb, it will still be rated as Class 4.
In some instances, a separate rating is assigned to the summit block of the climb. For example, a Class 3s5 means that the climb is mainly a Class 3 climb with a Class 5 summit block.
| Class 1 | – A walk or hike. A non-technical climb. – You don’t need to use your hands for climbing. – There are well-defined trails with no need for route finding. – Low chance of injury. – You don’t need to wear hiking shoes or boots. |
| Class 2 | – An easy scramble. A non-technical climb. – You need to use your hands occasionally for climbing. – The trail is intermittent or does not exist. – Slightly higher chance of injury. – You should wear hiking shoes or boots. |
| Class 3 | – A tough scramble. A non-technical climb. – You need to use your hands for climbing. – There are risks of falling and a high chance of injury. Falls can be fatal. – Beginners or unconfident climbers should use a rope for safety. |
| Class 4 | – An easy climb. A technical climb. – You need to use your hands for climbing on a vertical surface. – There are risks of falling and a high chance of injury. Falls can be fatal. – All climbers should use a rope for safety. |
| Class 5 | – A technical climb. – You need to use your hands for climbing on a vertical surface. – There are high risks of falling and a high chance of injury. Falls can be fatal. – All climbers should use a rope for safety. – Class 5 is further divided into sub-classes. – This is to define the increasing difficulty of rock climbs. They range from 5.0 to 5.14. – Letters suffixes were later added on for even further subdivision. The most difficult climb is currently rated 5.14d. |
Grade Rating System
| I | 1 to 2 hours of climbing |
| II | Less than half a day of climbing |
| III | Half a day of climbing |
| IV | A full day of climbing |
| V | 2 to 3 days of climbing |
| VI | 4 to 6 days of climbing |
| VII | 7 days or more of climbing |
Protection Rating System
| G | Adequate protection. |
| PG | Mostly adequate protection with some areas with poor protection. |
| PG 13 | Fair protection. There are risks of falling but unlikely to cause serious injuries. |
| R | Inadequate protection. There are risks of falling which is likely to lead to serious injuries. |
| X | No protection. There are high risks of falling which is likely to lead to serious injuries and death. |
