Area of a Rhombus Calculator
A rhombus has four equal sides and diagonals that cross at right angles. It fills exactly half of the rectangle drawn around its diagonals.
A = (p × q) / 2
Perimeter: P = 4 × √((p/2)² + (q/2)²)
Area of the rhombus
24ft²
- Perimeter
- 20 ft
- A = (8 × 6) / 2 = 24 ft²
- Side = √(4² + 3²) = 5 ft

How to find the area of a rhombus
Formula: A = (p × q) / 2. Perimeter: P = 4 × √((p/2)² + (q/2)²).
- Measure every length in the same unit. Mixing feet and inches is the most common mistake; convert first (6 in = 0.5 ft).
- Put the numbers into the formula above. The calculator shows each substitution with your numbers.
- Area comes out in square units (ft², m²). If you need a different unit, open "Area in other units".
Questions people ask
Is a square a rhombus?
Yes. A square is a rhombus with right angles, and its diagonals are equal, so A = d² / 2.
