Kite Area Calculator
For a standard kite whose diagonals are perpendicular, area is half the product of its diagonals.
How to use this calculator
- Enter both full diagonals in the same unit. The displayed area is expressed in that unit squared.
- Check the labels and units before using a result outside this page.
- Change one input at a time if you want to compare scenarios.
Formula and method
A = d₁d₂ ÷ 2
- A = d₁d₂ ÷ 2
- The formula assumes the usual kite shape with perpendicular diagonals.
Worked examples
Worked example
Diagonals 10 m and 4 m.
A = 10 × 4 ÷ 2 = 20 m².
A = 10 × 4 ÷ 2 = 20 m².
