What is the proper size for a cupola or finial?
• The proper size of a cupola or a finial will mainly depend on what kind of support you have inside of the attic. The cupolas range in weight from 35 pounds to 50 pounds. The finials average weight is 15 pounds. The height of the product is based on your desire, however a one-story home would usually have at least a 10″ x 10″ x 48″ finial or a 18″ x 18″ cupola. An elevated one-story home or a two-story home would usually have at least a 12″ x 12″ x 60″ finial or a 30″ x 30″ cupola. • In selecting the right size of a cupola for your structure, there should be one and one quarter inches of cupola base for each foot of unbroken roof line. Example: For 20 foot of unbroken roof line, the minimum cupola base size would be 24 inches. One other factor to consider is the amount of attic space. The more attic space, the larger the cupola should be.
