What Is a Kite in Geometry?

A kite is a quadrilateral with two pairs of consecutive (adjacent) equal sides. Its two diagonals are always perpendicular to each other, which is why the area formula simplifies to A = (1/2) × d₁ × d₂ — the same shape of formula as a rhombus. This calculator solves for the area, diagonal d₁, or diagonal d₂ given the other two values.

Kites are common in geometry puzzles, architecture, and design. A rhombus is a special-case kite where both pairs of adjacent sides are equal (all four sides match), and a square is a special-case kite with equal perpendicular diagonals.

How to Use the Kite Calculator

Select what you want to solve for using the solve-for toggle: area, diagonal d₁, or diagonal d₂. Enter the known values in any supported length unit (meters, centimeters, inches, feet, yards). The calculator uses the standard kite area formula A = (1/2) × d₁ × d₂ and automatically handles unit conversions.

Key Concepts

A kite's two diagonals cross at right angles, creating four right triangles. The four triangles combine to give the clean area formula A = (1/2)·d₁·d₂. Only one of the diagonals — the axis of symmetry — bisects the other. Unlike a rhombus, a general kite does not require all four sides to be equal, only the two pairs of adjacent sides.
