One of the important but mainly overlooked details when designing and building a screen porch or covered patio is the column size. So, how can you determine the appropriate size?
A good rule of thumb should take into consideration not only the size of the roof structure but also the height. the higher the porch, the more substantial the columns should be. Material or substrate also plays a role in the size of the porch column. For example, if you are utilizing a round fiberglass column, they are accompanied by a base cap that will make the column appear even wider. When you are using wood, perhaps there is an intent to wrap it with trim?
Most deck builders and porch builders will use 4×4 columns as a standard and upgrade to 6×6’s upon request. Archadeck of Charlotte will use 8×8’s or even 12×12’s for large open porches or porches that are 12′ off the ground or more.
