Sizing Your Cupola

Sizing your cupola is a very important consideration when determining what cupola is right for you. To assist you with this, below you will find sizing guidelines to help you select the size of cupola best for your home, shed, barn, garage or any other structure.

Selecting The Right Size Cupola

Before deciding which style cupola you're interested in, you should figure out what size cupola will fit your roof.  Cupolas make distinguished additions to homes, sheds, barns, garages or any other outdoor structure.  Our cupolas are used as a decorative accent to your building - lets ensure we get the correct sizing.

"Size" of our cupolas refers to the measurement across the bottom of the cupola's roof.

How to choose the right size cupola:

A good rule of thumb for selecting the right size cupola is to use 1.0" - 1.25" of cupola for every foot of unbroken roofline - the key is the unbroken roofline measurement

If you are considering 2 cupolas, a good rule of thumb is to use 1" of cupola for every foot of unbroken roofline measurement.

Please see the examples below.


For example:  20 feet of unbroken roof line, times 1.0" - 1.25”, equals a minimum cupola size of 20"- 25" square.  Our experience tells us this formula provides a balance between the cupola and the roof.  If the cupola is too small or too large, it will look disproportional.  If there is uncertainty between 2 sizes, we suggest going with the larger size as this will enhance the appearance of the cupola as it adorns your roof.


Another example with 2 cupolas:

When using more than one cupola, a good rule of thumb is to use 1" of cupola for every foot of unbroken roof line.  For example, for 24 feet of unbroken roof line, the minimum size for each cupola would be 24" square.

All cupolas are made to fit up to a normal 10/12 "pitch" (pitch is a term for the steepness of the roof).  If you have a steeper roof than 10/12, an extended base can be ordered.  To find out what the pitch of your roof is, see below.
