Area Calculator

🔷 Area Calculator – precise area & materials calculator Area Calculator is a browser extension for quickly and accurately calculating the area of rooms, floors, walls and other surfaces, and for working out how much material you need for a renovation project. ✨ Key features: 📐 Exact geometry from sides AND angles. Enter every side length and every corner angle, just as you measured them. The shape always stays closed and the area is calculated exactly, not estimated. 🔄 Smart shape adjustment. Change a side and the corner angles stay the same. Change an angle and all side lengths stay the same: only the nearest corners adapt so the shape closes correctly. 🖱️ Drag-and-drop vertices. Move any corner on the plan with the mouse, and all sides, angles and the area update live. Moves that would make the sides cross are blocked. 🏷️ Clear visual plan. Side lengths and corner angles are labelled directly on the drawing. 🔷 6 shape types. Custom polygon (3–20 sides), square, rectangle, triangle, L-shape and circle. 📏 Units. Work in centimetres or metres. The area is shown in both cm² and m². ⚡ Instant recalculation. Results update as you type. 🛡️ Input validation. Impossible values are rejected with a clear message, so you never get a broken shape or a wrong area. 💰 Materials calculator.
