Calculate the area of a triangle using base and height. If you're working with four-sided shapes, see our Rectangle Area Calculator. This tool includes automatic unit conversions for convenience.
Area represents the total surface inside a shape’s boundary. This calculator applies the standard geometry formula for this shape and multiplies the required dimensions together to produce the total area.
All calculations are performed instantly in your selected unit. Results are also converted automatically to square meters, square feet, and acres where relevant, making it easier to compare measurements across different projects.
A = (b × h) ÷ 2.
Height is the perpendicular distance from the base to the opposite vertex.
Yes—use the same unit for both.
