Consider what you plan to use the building for and how much room you require. Select the height, width and length of the project before laying out a pole barn. Make blueprints of the barn or purchase a pre-measured pole barn kit. Every 12 feet (3. 66 m) of length needs to have a 4 inch (10. 16 cm) by 4 inch (10. 16 cm) post as a brace when setting up a pole barn. [1] X Research source
