Why Classroom Spacing Matters
Classroom layout planning helps schools estimate how many desks fit while keeping minimum side and front clearance. Administrators can compare one-room capacity against class size and see whether staggered seating adds seats.
How Desk Capacity Is Calculated
The calculator uses seatable floor area, desk dimensions, and required gaps. Rectangular grids align rows in columns. Triangular grids offset every other row to pack more desks when aisle rules allow.

Frequently Asked Questions
What is seatable area?
It is the floor space where students sit, excluding teacher zones, aisles, and storage areas at the front or sides.
What gap should I use?
Many schools use six feet for social distancing, but you can enter any side and front spacing required by local policy.
What is a triangular grid?
Alternate rows are offset by half a desk width. This staggered layout can fit more desks than a strict rectangular grid.
What does groups needed mean?
If class size exceeds room capacity, groups needed is the number of split sessions required to seat everyone at once.
Are units in feet?
Yes. Enter room and desk dimensions in feet for consistent spacing results.
