Classroom Seating Capacity Calculator
Compare usable area and fixed seats for multiple classrooms after an entered circulation allowance.
What would you like to do next?
Keep area limits and seat limits separate
List each classroom with usable area, an entered area per student and the number of fixed seats. The calculator increases the space assumption by a shared circulation allowance, rounds area capacity down to whole people and uses the lower of area capacity or seat count. Combined capacity is compared with entered student demand.
Confirm safe and inclusive use of every room
Simple floor-area arithmetic cannot establish legal occupancy or a workable teaching layout. Egress, accessibility, supervision, furniture, laboratory equipment, sight lines, acoustics and local education rules may reduce or segment capacity. Use approved plans, current room condition and responsible facilities and teaching review before placing students.
Frequently asked questions
Why use the lower of two capacities?
Both entered area and fixed seating can limit the modeled places.
Is circulation added to space per student?
Yes. The shared allowance increases the entered area requirement.
Does this set legal occupancy?
No. Building and education requirements remain controlling.
