Pyramid Calculator
Pyramid Calculator is a browser-based calculator tool on CalcToolsBase. Free, browser-based Pyramid Calculator with instant, clearly-labelled results. No signup, no uploads. To use it, enter your values and view the result directly in your browser — no signup and nothing to install.
Pyramid Calculator takes your base side and height and gives back the volume and surface area, applying standard volume and surface-area formulas. It's a quick, browser-based way to find the volume and surface area of the solid.
About this calculator
The Pyramid Calculator gives you a quick way to find the volume and surface area of the solid. Enter your base side and height; it then returns the volume and surface area, worked out with standard volume and surface-area formulas the moment you calculate. It runs fully in the browser, so it is private by design and works offline once loaded.
Built with students, engineers and makers in mind, it keeps the workflow to a single step and shows the volume and surface area without clutter. There are no accounts, and your inputs stay in your browser and are never uploaded.
How to use
- Enter the base edge length.
- Enter the vertical height of the pyramid.
- Press Calculate to measure the pyramid.
- Read the volume and base area.

Technical notes
Pyramid Calculator uses volume = 1⁄3 × base area × height for the pyramid you describe.
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
Which pyramid does this calculate?
It calculates a square pyramid, whose base is a square with the edge length you enter.
How is pyramid volume calculated?
Volume is one third of the base area times the height: (1/3)b²h.
Is height the slant or vertical height?
Use the vertical height, measured straight up from the base to the apex.
Does the Pyramid Calculator send my data to a server?
No. The Pyramid Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
A square pyramid with base side 6 and height 9: volume = ⅓ × 6² × 9 = 108.
