Dome Calculator

Dome calculations are painful to do by hand. It’s not impossible, just time consuming. So I have written this simple calculation worksheet to help. It will calculate the most commonly needed measurements for a dome — both spherical or oblate.

For either calculation you enter the diameter, height, stemwall, and level information then click ‘Calculate.’ to get the results. Remember, if you change any one of these values, you must hit ‘Calculate’ again.

We also have the advanced calculator including the prolate calculations.
