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.

After being turned down by several other wood crafting companies who were not interested in my small job, Turntech said "Yes" and made the chair bottom spindles needed to repair my favorite colonial style maple chairs. Thank you! Turntech, i have my beloved chairs back good as new.

I ordered and received a porch post in 2020. I'm sorry I'm so late writing a review. Due to the weather and a broken ankle I haven't been able to install it yet. Customer service was great, The quality of the post is fantastic, I sent my own drawing copied from the other 150 year old posts on the porch and they matched it. I still need to paint the post and install it , I will upload a picture when I get there. An excellent woodworking company. I will use them again if I need a top quality post.
