CEILING LAYOUT CALCULATOR
Find the starting grid. Fast.
Enter a rectangular room, choose the ceiling module and centering method, then compare border cuts on a live reflected ceiling plan.
ROOM
Room size
Length runs East–West. Width runs North–South on the plan.
CEILING MODULE
Tile size
STARTING POINT
What should hit the room center?
Set each room direction independently. This lets you center a tile one way and a main runner or cross-tee row the other way.
The line option changes automatically between main runner and cross-tee row based on the selected main-runner direction.
Perimeter Preferences (Optional)Start with a full tile at a selected wall instead of balancing that axis.
A full-tile wall preference overrides the selected center choice on that room axis.
LIVE LAYOUT
Reflected ceiling plan
Starting-layout aid: Use the project RCP, specifications, fixture coordination, selected suspension system, manufacturer instructions, and applicable code requirements to establish the final ceiling layout. This tool currently assumes a rectangular room and standard orthogonal modules.

HOW IT WORKS
Ceiling grid layout calculator
Use the BidSimp ceiling layout calculator to compare common starting layouts in a rectangular room before drawing the full reflected ceiling plan. Standard 2' × 2' and 2' × 4' exposed-grid layouts typically use main runners at 4' on center; 2' × 2' layouts add intermediate 2' cross tees to create 24" × 24" modules.
Compare the center quickly
Switch between a tile-centered layout and a main-runner-centered layout to see how the perimeter cuts change. The plan redraws immediately and reports the resulting border tile dimensions at all four walls.
Catch tiny cuts before they surprise you
BidSimp flags any perimeter tile under 3 inches so you can test another starting point or a full-tile wall preference before carrying the layout into the project RCP.
