The rhombus area calculator is an excellent tool to determine the area of a rhombus, as well as its perimeter and other characteristics: diagonals, angles, side length, and height. Have a look at many ways you can find the diamond area: given diagonals of a rhombus, using base and height, side, and any chosen angle... Are you still wondering how to find the area of a rhombus or rhombus perimeter? Check the rhombus area formulas below, or just experiment with the tool.
A rhombus is a simple quadrilateral with all sides equal. The other names are an equilateral quadrilateral or a diamond (like the one from playing cards ♢). The fundamental properties of a rhombus are:
Every rhombus is a parallelogram and a kite.
There are three useful formulas for calculation of the area of the rhombus:
Why can we use any angle in the last rhombus area formula? Because we know that two adjacent angles are supplementary, and sin(angle) = sin(180° - angle). There are other variations of those equations (e.g., calculating the area given height and angle), but they are only simple trigonometric transformations of those three most popular rhombus area formulas.
Finding the rhombus perimeter is trivial if we know the side length – it's 4 × a. But what if we know only the diagonals of a rhombus? Let's check:
Also, you can use this formula:
Or just type the lengths of the diagonals into the rhombus area calculator!
Are you still pretty unsure how to use the calculator? Let's show its potential with a simple example:
Our tool is really flexible – if it's possible to calculate, it will do it. Usually, two given values are enough. Give it a try!
The answer is yes to both questions. Every square is a rhombus, as for a rhombus, the only necessary condition is that it needs to have all sides of equal length. As you know perfectly well, a square needs to have all sides equal and all four equal angles, so it fulfills the conditions to be a rhombus. Similarly, a rhombus is a parallelogram, as any shape needs to have two pairs of parallel sides to be a parallelogram – and the rhombus has them. So the rhombus is always a parallelogram, but a parallelogram is a rhombus only in a special case – for a parallelogram with four sides of equal length.

Given: Rhombus ABCD , AB = 10 cm, so BC = 10 cm ( All sides of rhombus are equal) Diagonal (AC) = 12 cm Formula Used: (1) Area of triangle = \(\sqrt {\left\{ {s\left( {s - a} \right)\left( {s - b} \right)\left( {s - c} \right)} \right\}} \) Where s is to semi perimeter & a, b and c are sides of the triangle (2) Area of rhombus (ABCD) = 2 × Area of Triangle Calculation: ⇒ Area of Δ ABC = \(\sqrt {\left\{ {s\left( {s - a} \right)\left( {s - b} \right)\left( {s - c} \right)} \right\}} \) ⇒ Semi perimeter of Δ ABC = (10 + 10 + 12)/2 ⇒ s = 16 ⇒ Area of Δ ABC = \(\sqrt {\{ 16\left( {16 - 10} \right)\left( {16 - 10} \right)\left( {16 - 12} \right)} \} \) ⇒ \(\sqrt {16 × 6 × 6 × 4} \) ⇒ Area of Δ ABC = 4 × 2 × 6 = 48 \(c{m^2}\) Area of rhombus (ABCD) = 2 × Area of Triangle ∴ Area of rhombus (ABCD) = 2× 48 = 96 \(c{m^2}\) India’s #1 Learning Platform Start Complete Exam Preparation
