Modular Grid Layout Calculator
Fit whole rectangular modules and uniform gaps into an available area.
What would you like to do next?
Fit modules and gaps in one orientation
Enter available length and width, module dimensions and a uniform inter-module gap in millimeters. The calculator counts whole columns and rows, calculates total modules, reports used grid dimensions and leaves the edge remainder visible in each direction. The gap is included only between modules, not automatically at the outer edges.
Review joints, cuts and orientation afterward
The arithmetic does not rotate modules, optimize centered margins, alternate patterns or include perimeter joints and trims. Real panels, ceiling grids, displays and furniture systems can also require tolerances and support locations. Compare orientations and build the final setting-out plan from manufacturer and project requirements.
Frequently asked questions
Are gaps added around the outer edge?
No. The entered gap is applied only between adjacent modules.
Can modules rotate automatically?
No. Enter the alternate orientation separately to compare it.
Are partial modules counted?
No. The result reports whole modules and leftover edge dimensions.
