How to Size Your Shed

1) What is the Purpose of Your Shed?

Considering the purpose for your shed is the most important step to choosing its size. What will you use your shed for?

  • Storing tools and gardening equipment
  • Storing outdoor play equipment: bicycles, go-karts, kayaks, etc.
  • Extra workspace
  • Securely storing potentially harmful lawn-care/auto-care chemicals
  • Or some combination of all of the above

Often homeowners find they need more space than they initially thought, but once you have determined your shed's purpose, then you can consider size options.

2) How Much Can I Fit in My Shed?

The table below provides a general guide to the space you will need for the various functions of your new building: 

Size of Shed Storage Items Standing Room Workspace
 64 Sq. Ft. (8’ x 8’)  Bicycles, Push Mower, Garden Tools  Yes  No
 80 Sq. Ft. (8’ x 10’)  Riding Mower, Cabinets, Garden Tools, Bikes  Yes Some
 100 Sq. Ft. (10’ x 10’)  Riding Mower, Push Mower, Garden Tools  Yes  Some
 120 Sq. Ft. (10’ x 12’)  Riding/Push Mowers, Work Tables, Bikes, Tools  Yes  Yes
 140 Sq. Ft. (10’ x 14’)  Mowers, Bikes, Tools, Work Tables, Wheelbarrow  Yes  Yes
 144 Sq. Ft. (12’ x 12’)  Mowers, Dirt Bike, Bicycles, Work Tables, Cabinets  Yes  Yes

Few people find they have built a shed too large for their needs. When preparing for your new building, it is better to plan to build extra space (Rmember, a building larger than 400 square feet will require a permanent foundation). 

3) What Space Saving Tricks Can I Employ?

For multi-purpose sheds, consider higher apex roofs that allow space for loft storage. Hooks and peg boards can help you store regularly used items without taking up floor space. Cabinets can double as work benches and tables to maximize the workspace available in your building. Your HOA or municipality will have guidelines and codes regarding the size and style of your shed. It is vital to abide by these, lest you face a fine or the confiscation of your shed.

"Our family had a great experience with Cardinal Buildings. We were able to walk thru the sheds they have on site to choose what was best for us. The office staff was very knowledgeable and the builder did a great job in our yard."
