CALCULATOR
Triangle Height Calculator
Find triangle perpendicular height from area and base. Example: Area: 12 m², Base: 2 m gives 12 m. Height is altitude, not sloped side. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation.
Height is altitude, not sloped side. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Solve A=bh/2 for h.
Accepted inputs: Area: 0.001 to 100,000,000 m²; Base: 0.001 to 1,000 m.
How the calculation works
height = 2 area/base
Worked example
With area 12 m², base 2 m, triangle perpendicular height from area and base is 12 m.
