Rhombus from Diagonals
Find area, side length and perimeter from perpendicular diagonals.
Your numbers
Area
Use consistent units. The result follows the assumptions you enter.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use A = d₁d₂/2 and s = √(d₁²+d₂²)/2. d₁ and d₂ are the rhombus diagonals in the same length unit. A is area and s is side length.
Find area, side length and perimeter from perpendicular diagonals.
Worked example
- First diagonal (m)

- 8
- Area
- 24 m²
- Side length
- 5 m
- Perimeter
- 20 m
Scope and limitations
Use consistent units. The result follows the assumptions you enter.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
