Estimate a classroom planning capacity from room size, reserved area and the space allowance you choose per learner.
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.
