Area of a Kite Calculator: Diagonals, Sides, Angle

Q: How do you calculate the area of a kite?

The standard formula is A = d1 × d2 / 2 , where d1 and d2 are the diagonals of the kite.

Q: Can I find the area of a kite from two sides and an angle?

Yes. If you know two sides and the included angle, use A = a × b × sin(θ) .

Area of a Kite Calculator: calculate kite area from diagonals or from two sides and the included angle. Reverse the kite area formula to find a missing diagonal, side, or angle from the area.

This calculator finds the area of a kite from two diagonals or from two sides and the included angle. It also works in reverse when the area is known and you want to solve for a missing diagonal, side, or angle.

The standard kite area formula from the diagonals is A = d1 × d2 / 2. If you know two sides and the included angle instead, the calculator can also use A = a × b × sin(θ).

That gives you two practical entry modes: one for the classic diagonal formula and one for side-and-angle geometry. Angle input can be entered in any supported angle unit, including radians.

Area of a Kite Calculator FAQs

How do you calculate the area of a kite?
The standard formula is A = d1 × d2 / 2, where d1 and d2 are the diagonals of the kite.

Can I find the area of a kite from two sides and an angle?
Yes. If you know two sides and the included angle, use A = a × b × sin(θ).

Can this calculator work backwards from the area?
Yes. It can reverse the kite area formula to solve for a missing diagonal, a missing side, or the included angle, depending on the selected mode.

What angle should be used in the side-and-angle formula?
Use the included angle between the two entered sides. The calculator supports the selected angle unit automatically, including degrees and radians.
