Cylinder Surface Area Calculator
Calculate lateral and total surface area of a cylinder.
How to Use the Cylinder Surface Area Calculator
Enter cylinder radius and height to calculate curved and total surface area.
Practical Example
For radius 3 and height 8, the curved area is about 150.80 square units and total area adds the two circular ends.
Factors That Affect the Result
Total area includes both end circles; lateral area does not. Use consistent radius and height units.
Frequently Asked Questions
Does total area include both bases?
Yes.
What is lateral area?
The curved side area only.
What units are returned?
Squared units.

Understanding Cylinder Surface Area
Total surface area of a closed cylinder is 2πr² + 2πrh: two circular ends plus the curved side. If only the side is being covered, use the lateral area 2πrh.
Decide which surfaces are actually part of the job before using the result for paint, labels, insulation or fabrication. Radius and height must use the same unit. For tanks or pipes with open ends, subtract the areas that are not present rather than using the closed-cylinder total automatically.
