Teacher zone, storage or other space not available to learners.

Use the figure required by your own school, policy or local rules.

0 means no extra cap.

Formula

Usable area = room length × room width − reserved area. Space-based capacity is the whole number of learners that fit when usable area is divided by your chosen area allowance. If you enter a policy cap, the calculator uses the lower limit.
