Room Layout Capacity Calculator
Estimate whole planning units from room area and an editable area allowance.
What would you like to do next?
Separate gross area from modeled usable area
Enter room length and width, subtract fixed or blocked area and choose an area allowance for each station or person. The calculator reports gross and usable area, whole planning units that fit by area and the remainder after those units. The allowance stays editable because furniture and activity types need different working space.
This is not a legal occupancy result
An area division cannot evaluate exits, aisle geometry, accessibility, fire protection, ventilation, furniture shape or local limits. Use the number only for early comparison, draw the actual arrangement and obtain the required qualified review before setting occupancy or opening a space to users.

It is entered floor area unavailable to the planned stations or people.
