Standing Room Capacity Calculator

Work out standing room capacity instantly with clear inputs, formula shown and shareable results.

About Standing Room Capacity Calculator

Capacity is the usable area, after deducting circulation routes, multiplied by the planned standing density in people per square metre. Densities above about four people per square metre remove individual control of movement, which is why licensed limits sit well below the geometric maximum.

Formula

Capacity

capacity = area x (1 - circulation share) x density

Worked example

With the default values below, Standing Room Capacity Calculator returns Standing capacity of 400. Change any input above and every figure here is recalculated in your browser.

Inputs used

Usable standing areaminimum 1 m2: 200 m2
Planned densityaccepts 0.1–6 people/m2: 2.5 people/m2
Share reserved for circulationaccepts 0–70 %: 20 %

Results

Standing capacity: 400
Usable area after circulation: 160.0 m2
Space per person at that density: 0.4000 m2
Capacity at a conservative 2 per square metre: 320

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Indicative only. Licensed capacity is set by your local safety authority.

Frequently Asked Questions

How is the Standing Room Capacity figure worked out?

capacity = area x (1 - circulation share) x density. Capacity is the usable area, after deducting circulation routes, multiplied by the planned standing density in people per square metre.

Why does this matter?

Densities above about four people per square metre remove individual control of movement, which is why licensed limits sit well below the geometric maximum.

What do I need to enter?

Enter usable standing area, planned density, share reserved for circulation. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
