Room Layout Planner
Sketch a simple floor plan on a grid — draw walls, drop in doors and fixtures, and get instant area and perimeter readouts. Export PNG or save your layout.
How this is calculated
Click on the grid to place wall corners. Snap closes to 0.25 m grid squares.
Close the room by clicking near the first point, or use the Close room button (needs 3+ points).
Area uses the shoelace formula on your closed polygon. Perimeter sums each wall segment.
Pair with the Tile Calculator or Paint Calculator using the bounding-box dimensions.
