Post-Frame Building Width Guidelines
Sizing FootingPad for Post-Frame Buildings
Our pole barn width charts offer helpful guidelines for choosing FootingPad size based on the width of your post-frame building. Please note, these charts are only guidelines and do not replace advice from an engineer or other design professional.
How to Use These Charts
Use the column with the snow load rating in your area to determine the size FootingPad you need. If side doors larger than 8′ are used, larger footings will be needed for posts on either side of door.
Built in variables: Post spacing along side wall of 8 feet, dead load of 5 psf. If your proposed building lands in an “adjust” cell, then modify the width of your building as load capacity is too high for the largest FootingPad of 24″.
