What is the Rhombus Area Calculator?
Calculate the area and side length of a rhombus from its diagonals. These geometry calculators work out area, perimeter, volume and surface area for common shapes. Units are flexible — enter every length in the same unit and the answer comes back in that unit (squared or cubed).
How to use the Rhombus Area Calculator
- Enter your diagonal 1, your diagonal 2.
- Results update automatically as you type; you can also press Calculate.
- Read the output: area, side length, perimeter.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With diagonal 1 = 10, diagonal 2 = 6, the Rhombus Area Calculator returns area: 30; side length: 5.83095189485; perimeter: 23.3238075794.
Tips for better results
- Keep all measurements in one unit before calculating.
- Area units are squared (m², ft²) and volume units are cubed (m³, ft³).
- Use our area and volume converters to switch units afterwards.
