Lintel: Floor Plan Sketch

Sketch a room, a flat or a whole floor in minutes. Drag out walls that snap to clean lengths and angles, drop in doors and windows, and watch the square footage fill in. Every plan saves itself as you draw, keeps a history you can roll back, and stays yours: no account, no plan limits, and nothing you drew is ever locked.

Draw to scale without learning CAD
- Room tool: drag a rectangle and get four walls and a labelled room in one move.
- Wall tool: chain walls with length, angle and alignment snapping you can see. Walls join cleanly at corners and T-junctions.
- Type an exact length or angle on any wall, in feet and inches or metric.
- Doors, double doors, sliding doors, openings and windows that sit on the wall, with swing direction.
- Dimension lines that follow the walls, wall length labels, free text notes.
- 84 furniture shapes you can resize and rotate.
- Undo and redo up to 200 steps.

Square footage, done for you
Every closed room shows its interior area, and the plan shows the total floor area.
