Surface Area Calculator

Calculate the total surface area of common three-dimensional shapes with accurate formulas, flexible units, and instant converted results.

Ball Surface Area

Calculate the total surface area of a sphere from its radius.

Radius (r)

Cone Surface Area

Calculate the closed surface area of a circular cone using the base radius and vertical height.

Base Radius (r)

Height (h)

Cube Surface Area

Calculate the total surface area of a cube from the length of one edge.

Edge Length (a)

Cylindrical Tank Surface Area

Calculate the total surface area of a closed cylinder, including both circular ends.

Base Radius (r)

Height (h)

Rectangular Tank Surface Area

Calculate the total surface area of a rectangular box or closed rectangular tank.

Length (l)

Width (w)

Height (h)

Capsule Surface Area

Calculate the surface area of a capsule by combining the spherical ends with the cylindrical middle.

Base Radius (r)

Cylinder Height (h)

Cap Surface Area

Calculate a spherical cap surface area. Provide any two of the three values: base radius, ball radius or height.

Enter exactly two values. The missing value will be calculated automatically.

Base Radius (r)

Ball Radius (R)

Height (h)

Conical Frustum Surface Area

Calculate the total surface area of a closed right conical frustum using its top radius, bottom radius and height.

Top Radius (r)

Bottom Radius (R)

Height (h)

Ellipsoid Surface Area

Estimate the surface area of an ellipsoid using its three semi-axis dimensions.

Ellipsoid surface area does not have a simple exact elementary formula. This calculator uses the standard p ≈ 1.6 approximation used by the referenced calculator.

Axis 2 (b)

Axis 3 (c)

Square Pyramid Surface Area

Calculate the total surface area of a square pyramid from its base edge and vertical height.

Base Edge (a)

Height (h)
