Calculate areas for 7 common shapes. Add material thickness for weight estimation, or enter unit price for cost calculation. All results are cumulative.
Switch to 3D Surface Area CalculatorMetal Weight CalculatorArea = l × w
Area = √[s(s-a)(s-b)(s-c)] where s = (a+b+c)/2
Area = (b₁ + b₂) / 2 × h
Area = π × r²
Area = (θ / 360) × π × r²
Area = π × a × b
Area = b × h
