Room Air Volume per Person Calculator

The Room Air Volume per Person helps estimate m³/person in the context of home comfort. It uses the specific input quantities Room length m, Room width m, Ceiling height m and Occupants rather than relying on a generic percentage or a hidden default. Enter measurements with the units displayed next to each field, and compare the calculated result with the worked example below. Volume is not ventilation; follow applicable indoor-air guidance. It runs locally in the browser; no personal account or server calculation is required.

How to use this calculator

  1. Enter Room length m using the stated units, then confirm the number reflects your own situation.
  2. Enter Room width m using the stated units, then confirm the number reflects your own situation.
  3. Enter Ceiling height m using the stated units, then confirm the number reflects your own situation.
  4. Enter Occupants using the stated units, then confirm the number reflects your own situation.
  5. Review the displayed result and the stated limitation before using it in a real plan.

Room Air Volume per Person equation and assumptions

Room length m*Room width m*Ceiling height m/Occupants → m³/person

  • The equation combines Room length m, Room width m, Ceiling height m, Occupants in the order shown and returns m³/person.
  • Volume is not ventilation; follow applicable indoor-air guidance.

Worked examples

Worked example: Room Air Volume per Person

Try these values: Room length m = 6, Room width m = 4, Ceiling height m = 2.5, Occupants = 4.

Evaluate Room length m*Room width m*Ceiling height m/Occupants with the example values.

The calculated result is approximately 15 m³/person. Change the input values to explore a different scenario.

Understanding the result

The output is expressed in m³/person, using the input values you supplied.

Volume is not ventilation; follow applicable indoor-air guidance.

Important notes

Volume is not ventilation; follow applicable indoor-air guidance.

Treat this as a planning or explanatory estimate. Check constraints, units, and real-world data where precision matters.
