Cylinder Surface Area Calculator
Surface area of a cylinder.
Enter the values and press Calculate.
How to use Cylinder Surface Area Calculator
Total surface area is two pi r times the radius plus the height.
Open Cylinder Surface Area Calculator on toolpermarket and enter your values above.
Enter the radius and height of the cylinder in the fields above, then press Calculate.
Read the result below the form. You can change any input and press Calculate again to compare scenarios.
Worked example. A radius of 5 and height of 10 gives a surface area of about 471.2.
When to use Cylinder Surface Area Calculator. Use it for cans, tubes, or wrapped cylinders.
Practical note. The tool adds the two circular ends and the curved side. Use the same unit for radius and height to get the area in that unit squared.
When you actually reach for this
- Use it for cans, tubes, or wrapped cylinders.
Where this tool stops being accurate
- Uses the units you enter consistently (all meters or all cm); mixing them silently breaks the result.
- It models ideal shapes, not real-world tolerances or material waste.
Frequently asked questions
Does this include both ends?
Yes, the total area includes the two circular bases.
Why is my area wrong?
Usually mixed units - if one side is in cm and another in m, convert first. The formula is exact once units match.
