Easily calculate the area, perimeter, and diagonal of any rectangle. Our free online tool provides instant, accurate results from your input width and height. Simplify your geometry, design, or construction calculations today!
Formula:
To calculate the properties of a rectangle, use the following formulas:
- Area (A): `A = width × height`
- Perimeter (P): `P = 2 × (width + height)`
- Diagonal (D): `D = √(width² + height²)` (Pythagorean Theorem)
Where:
- width: The length of the shorter side of the rectangle.
- height: The length of the longer side of the rectangle.
