How to Calculate the Square Footage of a Triangle
The area of a triangle is half the product of its base and height. To find the square footage, convert both measurements to feet first, then apply the formula A = 1/2 x base x height.
Formula and Conversions
Triangle Area Formula
Half the product of base and height.
A = 1/2 x base x height
Inches to Feet
Divide inches by 12.
1 foot = 12 inches
Yards to Feet
Multiply yards by 3.
1 yard = 3 feet
Meters to Feet
Multiply meters by 3.28084.
1 meter = 3.28084 feet
Common Uses
- Calculating material needed for triangular roof sections or gables.
- Estimating the area of triangular garden beds or landscaping features.
- Determining paint or siding coverage for triangular wall sections.
- Architectural and construction planning for non-rectangular spaces.
Important Notes
The height must be perpendicular (at a right angle) to the base. If you only know the sides of a triangle, you can use Heron's formula to find the area, but this calculator specifically uses the base-height method for square footage calculations.
