About this calculator
Use the Cylinder Calculator to find the volume and surface area of the solid. It reads your radius and height, computes the volume and surface area with standard volume and surface-area formulas, and shows the result clearly labelled. Because the calculation happens in your browser, your figures never leave the page and there is nothing to install.
Made for students, engineers and makers, it gives the volume and surface area from your radius and height in one step — clearly laid out, free to use, and computed entirely on your device.
How to use
- Enter the base radius.
- Enter the height.
- Press Calculate to measure the cylinder.
- Read the volume and the lateral and total surface areas.

Technical notes
Cylinder Calculator uses volume = πr²h and surface area = 2πr(r + h).
Results assume exact, idealised shapes; real-world measurement error is not included.
All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.
FAQ
How is cylinder volume calculated?
Volume is the base area times the height: πr²h.
What is the difference between lateral and total surface area?
Lateral surface is just the curved side; total surface also adds the two circular ends.
What units should I use?
Use any single length unit consistently; volume comes out in that unit cubed and area in that unit squared.
Does the Cylinder Calculator send my data to a server?
No. The Cylinder Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
A cylinder with radius 3 and height 5: volume = π × 3² × 5 = 141.37.
