A rhombus has four equal sides, and its diagonals cross at right angles. The diagonal formula treats the rhombus as four right triangles, producing area d1*d2/2.
⚠Diagonal lengths must be nonnegative. This calculator uses the diagonal area formula.
How Rhombus Area Works
The diagonals split a rhombus into four right triangles. Multiplying the diagonals and halving the product gives the total area.
