Take a few moments to review the information presented here to help you select the right cupola. Cupolas and weathervanes make great-looking additions to homes and other buildings. Cupolas can be used for ventilation or can just be a decorative accent.

In selecting the right size cupola for your building, a good rule of thumb is one and a quarter inches (1.25") of cupola base for every foot of unbroken roof line. The key idea here is the unbroken roof line measurement.

Copper Cupola "Rule of Thumb" for sizing

For example, if a roof section measures 20', the minimum cupola base should be 20". However, we usually suggest the next size larger. Our experience tells us it provides for a more pleasing appearance. If the cupola is too small, it will look like a bird house. In fact we recommend going one or two sizes larger, especially if there is significant height to the structure, or an adjoining building.
