A standard 24 ft x 24 ft barn may be enough to start with, but if you expand it, you'll need more space. Many of our customers who use their barns exclusively as workshops, carpentry, welding, CNC, etc. find it beneficial to choose a 30 ft x 40 ft barn or a little larger. When you're trying to make a decision about the proper height of the barn with poles, it's always a good idea to decide what you're going to store in your building.
You can build a building with a pole structure of almost any size, but if you keep your dimensions at 8 feet in the center (or 10 feet in the center at the ends of the gable) you can save money and design problems, since the posts measure 8 feet in the center and the trusses fall 8 feet in the center or 4 feet in the center or 4 feet in the center. To calculate the square footage of a barn with poles, simply multiply the length by the width of the building. For example, while the smallest average size of a pole building is 10 x 20, anything smaller than 20 x 30 results in less profitability in terms of size and value. It's always useful for the post frame builder if you have a general idea of the type of pole barn you want to build.
A larger space can make it easier to build horse stables, move equipment in and around the pole barn, and use space for large machinery. It is difficult to give one size fits all because each pole construction is different depending on how the person wants to use it. Most of the time, when someone decides to build a barn with poles, they have a good reason to do so.
