About this tool
Choose a shape and enter the dimensions marked on its diagram. Add or subtract rectangles, triangles, circles and L shapes. For irregular spaces, enter directions and lengths to draw exact edges, or drag template corners with labelled grid snapping.
Area measurement
Choose a task. Inputs stay in this page only.
Use Simple / draw for rectangles, circles and base-height triangles. Choose a shape tab above for other dimensions. Each shape keeps its own measurements.

Worked examples
Circle with diameter 2,000 mm
Approximately 3.142 m²Choose mm, select Circle and enter diameter A=2000. The radius is 1 m, so the area is π×1².
Place a point at (3.2, 3.3) m with 1 m snapping
Snaps to (3, 3) mNew points and dragged vertices align to the nearest grid position. Changing the spacing does not resize completed shapes.
Questions & answers
Can I enter a radius for a circle?
The field expects the diameter. Double a known radius first: a 1 m radius means a 2 m diameter.
Does changing grid spacing change existing areas?
No. The spacing affects new points and future vertex movement. Turn snapping off to enter arbitrary precise coordinates.

Side length (m): 2
Hexagon area: 10.392305 m²Using these sample input values gives the first labelled output above. Requires six equal sides and six equal internal angles.
Questions & answers
Can I use the default numbers for purchasing or safety certification?
No. Replace the examples with your real values. Requires six equal sides and six equal internal angles.
