# Climbing: Artificial Wall Holds Amount

This brief post tries to answer a simple question: "How many (climbing) holds will I need?"...

### Building a Climbing Wall

The **perfect** amount will obviously **differ** as per each individual needs. However, a rough calculation can be used to determine the **minimum number** of (climbing) holds:

- Method #1 multiplies the climbing area (in squared meters) by a "rule of thumb" a constant of
**5**(e.g. 2*3*5 = 30):

- Method #2 uses a "more scientific" approach when separating the athletes as per their age. Assuming a 32 square feet (4x8) climbing area, the number of holds are as follows:

Athlete Category | Number of Holds |
---|---|

Toddler | 32 |

Elementary School | 24 to 32 |

Middle School | 18 to 24 |

High School | 16 |

Bouldering wall | 32 |

Top Rope wall | 16 to 24 |

### Conclusion

Assuming that:

and

it is obvious, that the area considered by the second method is roughly **half the size** of the area considered by the first method.

Therefore, the recommendation of the first method to use at least 30 holds **pretty much matches** the recommendation of the second method (considering the high school category while doubling its numbers: 2x16 = 32).
