What is a good route density for a climbing gym?

A common guideline is 1–2 routes per 100 sq ft (roughly 10 m²) for a commercial gym. Bouldering walls can go denser (2–4 routes per 100 sq ft) since routes are shorter, while lead walls benefit from lower density to reduce clutter.

How is route density calculated?

Route density = number of routes ÷ total wall area. Coverage ratio adds average route length to show what fraction of the wall surface is actively occupied by holds.

Does route length affect density?

Yes. Longer routes occupy more wall real estate and their hold lines need separation to avoid confusion. The coverage ratio accounts for route length so you can see total occupied area.

What units does this calculator support?

You can enter dimensions in feet or meters using the unit toggle. All outputs update instantly when you switch units.

Why does the coverage ratio matter?

Coverage ratio tells you what percentage of wall surface has holds. Above ~60–70% coverage, holds from different routes start to interfere visually and physically, making setting harder and climbs confusing.
