There is an old rule of thumb for choosing the right size cupola.

For every foot of unbroken building ridgeline, you should have one inch of cupola”,
or, “One foot equals one inch”
So, measure the length of your building’s ridgeline and convert the footage directly to inches.

Below are a few examples of our more popular sizes using this rule of thumb.

Cupolas up to 6′ (72″) are available for larger structures.
