What Shed Size Do I Need?

The right shed size depends on what you plan to store, how you’ll use the space, and how much room you have on your property. Small sheds are great for tools and lawn equipment. Medium sheds give you space for workshops or riding mowers. Large sheds are best if you need a multi-use space like a home office, gym, or garage alternative.

In this shed size guide, we’ll explain how to choose the best shed size for your needs, so you can avoid overspending, avoid headaches, and get a shed that works for the long term.

How to Choose The Right Shed Size

Picking the right shed size isn’t just about what fits in your backyard; it’s about what fits your lifestyle. Here are the key factors to keep in mind:

What are you Storing (Now and Later)?

Make a list of everything you plan to store in your shed, including:

  • Lawn equipment (push or riding mower, trimmers, gas cans)
  • Tools, shelving, storage bins
  • Hobby gear (bikes, camping equipment, sports gear)
  • Seasonal decorations or patio furniture

Pro Tip: Also take future storage needs (such as seasonal) into consideration.

How will you Use the Space?

Will your shed be used solely for storage, or do you also want space to work, or relax? 

  • Workshop or hobby space
  • Potting station or garden shed
  • Home office, gym, or creative studio

What fits your Property?

Choosing your shed is just the first step. Making sure it works with your yard is just as important.

Measure Your Available Space

Start by marking off the area where you want to place the shed. Use stakes, string, or spray paint to outline possible footprints. Then ask yourself:

  • Is the area flat and level, or will it require grading?
  • Will there be enough clearance around the shed for doors and windows to open freely?
  • Do you want space for landscaping or pathways around it.

Do you need space to walk around? Cramped sheds make it hard to access your things. Plan for walkways, shelf space, and clear zones for doors or windows to open easily.

Consider Foundation Requirements

Most sheds, especially larger ones, need a proper foundation to sit level and stay protected from moisture. Common foundation types include:

  • Gravel pad (great for airflow and drainage)
  • Concrete slab (durable and permanent)
  • Pressure-treated skids (often used for portable sheds)

Each base takes up a little more room than the shed itself, so make sure to account for that in your measurements.

Don’t Forget Zoning Rules and Setbacks

Local regulations can impact how big, and where your shed can be. Always check:

  • Zoning setbacks (how far the shed must be from property lines, fences, or other buildings)
  • Easements or utility lines that could limit placement
  • Permit requirements (some towns require permits for sheds over a certain square footage)

HOA Restrictions May Apply

If you live in a neighborhood with a homeowners association (HOA), be sure to check their guidelines too. HOAs often have rules about:

  • Maximum shed size or height
  • Color and exterior materials
  • Shed placement in relation to fences or homes

FAQs About Shed Sizes

Small sheds like 8×10 or 8×12 are usually the best value for basic storage. They’re affordable to build or buy, and in some cases, they typically don’t require permits or complicated site prep (be sure to check with your local zoning office). If you only need space for lawn tools, bins, or seasonal items, this size is a great investment. Learn more about shed permits in our article Shed Permits in Virginia

Permit rules vary by location, but in many parts of Virginia, you can build a shed up to 256 square feet (often 16×16 or similar) without a permit, as long as it meets setback and height requirements. Always check with your local zoning office to be sure.Learn more about shed permits in our article Shed Permits in Virginia

The 10×12 shed is one of the most popular choices. It offers enough room for a riding mower, tools, and workspace, without taking up too much of your yard. It’s a solid middle-ground option for most homeowners.

Maximize space in a small shed by using vertical storage like wall hooks, pegboards, and overhead shelving. Group items by use (gardening, tools, storage bins) and keep walkways clear so everything stays accessible.

Small Sheds (up to 8×12):

Recommended: Gravel pad with pressure-treated wood frame or skid foundation
Why: These are budget-friendly, quick to install, and provide sufficient support for lighter structures.
Best for: Tool storage, garden supplies, or seasonal items

Medium Sheds (10×12 to 12×16):

Recommended: Gravel pad with timber border or concrete blocks with leveling
Why: These provide a more stable base for heavier contents like riding mowers or workbenches.
Best for: Multi-use storage, workshops, or hobby spaces

Large Sheds (12×20 and up):

Recommended:Concrete slab or engineered gravel pad with proper drainage
Why: Larger, heavier sheds need a solid, permanent base to prevent shifting or settling over time.
Best for: Garages, backyard offices, or sheds with plumbing/electric

A shed with at least 7 to 8 feet of interior wall height gives you enough space for storing ladders, rakes, or standing equipment like snowblowers. If you’re adding shelving or hanging storage, extra wall height can keep things accessible without feeling cramped.
