What Our Customers Say

12x20 Shed FAQ's

Here are questions we are often asked about buying a 12x20 shed

The inside of a 12x20 shed from Overholt & Sons measures 12 feet wide and 20 feet long, giving you a total of 240 square feet of floor space. However, keep in mind that the actual usable area might be slightly reduced due to walls and other internal structures.

Make sure your 12x20 shed has a strong start with proper site preparation! Begin by leveling the ground, establishing effective water drainage, and building a solid foundation. For a simple, DIY-friendly solution, consider a gravel base—it provides excellent stability and helps manage moisture effectively.


Every shed has its own maintenance requirements! For wooden sheds from Overholt & Sons, routine inspections, fresh paint or stain, and pest control help keep them in top condition. Metal sheds require lower maintenance—just give them a periodic clean and check for any rust or wear to keep them looking great.
