Anyone planning a climbing wall will sooner or later ask themselves the same question: How many climbing holds per square meter How many holds does the wall need? Too few holds quickly make any wall boring, too many without a plan make it cluttered. This guide shows guidelines for home walls, spray walls, and training walls – and how to sensibly distribute the holds according to size and type.
- Homewall guideline: According to Bergzeit, 250–300 holds are sufficient for a 3 × 4 m area – around 20–25 per m².
- Lower limit: The fun starts at around 200 holds.
- Spraywall: It requires significantly more holds and footholds than a normal home wall.
- Grid: 15 cm grid ≈ 50 T-nuts per m², 20 cm grid ≈ 25.
- Mixture: Many footholds and small handholds, plus some large handholds and volume.
Guideline values per square meter
There's no fixed standard for hold density – it depends on the purpose of the wall. As a guideline, the Bergzeit magazine suggests that 250 to 300 holds are perfectly sufficient for a 3 x 4 meter wall. This translates roughly to... 20 to 25 handles per square meter.
| Wall type | Goal | Grip density |
|---|---|---|
| Home wall / Training wall | Fixed grip pattern, many boulder problems in a small area | approximately 20–25 handles per m² (guideline value based on 250–300 handles on 12 m²) |
| Spraywall | Choose your boulder freely, maximum variety | significantly denser than a normal home wall |
| Wall with bolted bouldering routes | Individual boulders in different colors, regularly re-routing | Depending on the number of boulders; holds are planned for each boulder. |
Here's how to calculate your grip count
- Measure area: Width × Height of the climbable surface, excluding the area behind the volume.
- Choose a guideline value: Approximately 20-25 handles per m² for a home wall, more for a spray wall.
- Plan for steps: A large portion of the holds should be small footholds – they make the wall usable for all levels.
- Start with one set: A mixed set as a basic kit, then supplemented selectively.
Example: A wall measuring 2.5 × 3 m has an area of 7.5 m². With 20–25 holds per m², this results in approximately 150–190 holds. For a spray wall on the same area, there can be significantly more.
It's better to plan for many small footholds and medium-sized holds first, rather than a few large jugs. Large holds look good on the wall, but it's the many small footholds that transform a single surface into a variety of boulder problems.
The right mix
Small footholds and edges for precise footwork – the largest group on every wall.
For finger strength and technical moves, at multiple depths.
For body tension and friction – View sloper.
For beginners, warm-up and new angles – Macros & Volumes.
Finished Climbing hold sets They already come with a balanced mix of sizes and grip types. The article explains the different grip types available. What types of climbing holds are there?.
Handles and T-nuts
The number of handles is closely related to the grid spacing of the T-nuts. According to Bergzeit, a 15 cm grid equates to approximately 50 T-nuts per square meter, and a 20 cm grid to approximately 25. More nuts than handles are standard: this allows sufficient leeway when tightening and loosening them. The article explains how the grid is planned. T-nuts for the climbing wall. For your own training wall, it's also worth taking a look at Build a spray wall.

Frequently Asked Questions
How many climbing holds do you need for a bouldering wall at home?
According to Bergzeit magazine, the fun starts at around 200 holds. For a wall measuring 3 x 4 meters, 250 to 300 holds are perfectly sufficient. This roughly corresponds to 20 to 25 holds per square meter.
How many T-nuts per square meter are advisable?
With a 15 cm grid, there are approximately 50 T-nuts per square meter; with a 20 cm grid, approximately 25. More nuts mean more options for repositioning. More information can be found in the article. T-nuts for the climbing wall.
Should you buy all the handles at once?
Not necessarily. A solid basic set with plenty of footholds and durable grips is a good start. You can then selectively add to it – for example, with slopers, crimps, or... volume.
Do you count volume when determining the number of handles?
Volumes don't replace handles; they create new surfaces and angles. Handles and footholds can also be mounted on a volume – thus creating many new movement possibilities with minimal wall space.
