TurnTech’s Front Porch Post Size Guide

Building or renovating a front porch starts with the posts. Not only do they perform the all-important job of supporting your roof, but these columns are a central focal point of the style you’re creating. To help you finalize the specifics of your design, we’re highlighting the most common front porch post sizes for both height and diameter.

At TurnTech, we’re a custom woodshop that builds and ships wood products all across the country. While we build a wide range of wood accents, porch posts are undeniably one of our signature items. Check out our front porch post size guide to find the right fit for your project and place your order when you’re ready!

Slim porch posts for decor and support


Common Wood Column & Post Sizes: Length & Width  

There are two distinct styles of porch posts, and each comes in slightly different standard sizes. The first type is the traditional porch post that has a slimmer profile and comes with squared bases and tops. The second type of posts is the classical wood column style, which are larger in diameter and feature a circular capital and base. These are the most common wood column sizes for each style:


Traditional Porch Post Sizes

Length: 8 feet is a standard length for the vast majority of porches, however 9-foot and 10-foot posts are popular custom options. We build up to 12-foot tall porch posts.

Width: 3.5 inches is the standard size for the squared base of the posts, while 5-inch wide columns are another common size. We have also custom built 4.25-inch, 5.5-inch, and 6-inch wide options are used in some designs.

In order for porch posts to be taller, they need to be designed with a wider base in order to support the added height. However, any style can be turned into all different porch post sizes. Discover some of our favorite front porch post ideas!

Wood Column Sizes

Length: When length is concerned, wood column sizes vary greatly – 8 feet, 9 feet, 10 feet, 11 feet, and 12 feet long columns are all popular options.

Diameter: 8, 10, and 12 inches are the standard sizes. When columns are carved in a tapered style, the bottom two thirds of the column will be approximately 2 inches wider.

Column style porch posts can be carved with a variety of interesting patterns, including fluting, roping, and tapering. From both a visual and a practical standpoint, a bigger porch necessitates a larger column. Firstly, the columns are load bearing, so they need to be able to handle the weight of a larger porch roof. In addition, smaller columns will look out of place on a stately, southern style porch.

Interior Column Sizes & Uses

Homeowners often fall in love with the grand look of columns when re-designing their front porch, and then feel compelled to incorporate them throughout the interior of their homes as well. Creative designers use wooden columns in interior design in a huge variety of different rooms. These are the most common wooden column sizes for inside the home.

Length: While 8-feet is the most common length for a full-sized interior column, there are many designs that make use of half columns which tend to be 4-feet or 5-feet long.

Diameter: 6 inches in diameter is the by far the most common interior wood column size. Since interior columns are more likely to be decorative than load bearing, smaller diameters are possible.

Once again, our interior columns provide all of the same style options as exterior columns, meaning that our signature roping, fluting, and tapering can be used to enhance almost any room in your house.

I ordered a bunch of corbels for a large bar I was building. Their prices were great and they shipped quickly. Communication was great as well. I was very pleased with what I received and would definitely purchase from them again in the future.

They did superior project for the columns on my front porch. The house will be 100 years old in 2024 and the parts of the columns they made fit the time period. The 1st photo has the new torso made from Spanish cedar installed under this column and the remaining torso beside it. All 9 are now installed. The 2nd photo is the same column with the rotted torso.
