Calculate the area of a rhombus from diagonals, base and height, side and height, or side and angle. Estimate square feet, square inches, square yards, square meters, perimeter, waste, material quantity, and project cost.
Diagonal mode:
The calculator multiplies diagonal 1 by diagonal 2, then divides by 2 to estimate rhombus area.
Base and height mode:
The calculator multiplies base by perpendicular height to calculate area.
Side and height mode:
The calculator uses the side length as the base and multiplies it by the height.
Side and angle mode:
The calculator squares the side length, then multiplies by the sine of the included angle.
A rhombus area calculator helps estimate diamond-shaped or angled spaces for tile layouts, flooring patterns, land sections, gardens, concrete, walls, pavers, and design work.
It can help calculate square footage, compare area units, estimate material quantity, add waste, and estimate project cost.
Your result shows the rhombus area, side length, perimeter, height, area with extra waste, estimated pieces or units needed, and estimated cost based on the values you enter.
If you know the diagonals, multiply diagonal 1 by diagonal 2, then divide by 2. You can also multiply base by height if those measurements are known.
The most common formula is Area = (Diagonal 1 × Diagonal 2) ÷ 2. Another formula is Area = Base × Height.
Square the side length, then multiply by the sine of the included angle. The formula is Area = Side² × sin(Angle).
Multiply the side length by 4 because all four sides of a rhombus are equal.
Yes. Diamond layouts and angled cuts often create extra waste. For tile, flooring, pavers, fabric, and pattern layouts, adding 5% to 15% extra is commonly helpful.
