But there's a right way and a wrong way to size and install columns on your home.
Getting the details right is the difference between an "ok" design and a handsome, timeless façade.
A common mistake is creating columns that are too narrow for their height. There's room for a little variation in diameter but typically, the height of columns should be around 7 and 9 times the diameter at the base.
The top photo shows very well proportioned Doric columns - their height/diameter ratio is close to the proper standard. And that's a big part of what makes them look great, and why this building has been a timeless classic for many decades.
Another big "oops" with columns (and this one is very common) is setting the columns too far in from the face of the horizontal construction (the entablature) above.
Finally, in the last photo, the face of the columns line up (more or less) with the face of the entablature; the capitals stick out a little bit. That's the right way.
In fact, this porch is just right in every detail, including the height/diameter ratio. Nice!
