Picking the right size shed is one of the most important decisions you’ll make. Too small and you’ll outgrow it within a year. Too big and you’re paying for space (and a larger footprint) you don’t need. The goal is to match the building to how you’ll actually use it — both now and a few years from now.
Here’s a clear, no-nonsense guide to help you decide.
Quick Size Guide by Common Use
| What You’re Storing or Using It For | Recommended Size | Why This Size Works |
|---|---|---|
| Lawn mower, basic tools, garden supplies | 8×10 or 8×12 | Compact but functional. Fits a push mower, tools, and seasonal items. |
| Riding mower + tools + extra storage | 10×12 or 10×14 | Most popular all-around size. Comfortable walking room and shelves. |
| Workshop, hobby space, or serious storage | 10×16 or 12×16 | Room for a workbench, tools, and still walk around. Great for serious DIYers. |
| Single car, ATV, motorcycle + storage | 12×20 or 12×24 | True single-car garage size with extra space on the side. |
| Two-car garage or large workshop | 20×24, 24×24, or larger | Full vehicle parking plus work or storage zones. |
| Greenhouse / potting shed | 8×12 to 12×16 | Enough height and light for plants while remaining manageable. |
| Outdoor sauna | 7×8 to 8×10 | Designed for 2–4 people with proper seating and heater space. |
Detailed Breakdown of Popular Sizes
8×10 and 8×12 Best for pure storage. Think lawn equipment, holiday decorations, bikes, and garden tools. These are budget-friendly and fit in tight side yards or smaller properties. Many customers start here and later wish they had gone one size up.
10×12 and 10×14 The sweet spot for most homeowners. A 10×12 gives you solid storage with room to walk. A 10×14 starts feeling like a real small workshop. These sizes are easy to deliver, usually don’t trigger the strictest permit requirements, and still look proportional in most backyards.
10×16 and 12×16 Ideal once you want a proper workspace. You can fit a workbench along one wall, store a riding mower, and still have open floor space. Many of our customers who do woodworking, small engine repair, or serious gardening end up in this range.
12×20 and 12×24 These cross into garage territory. A 12×20 can park a car or truck with room left over. A 12×24 is even more comfortable and is one of our most requested garage sizes. Add a loft or side door and it becomes extremely versatile.
Larger Garages (20×24 and up) When you need true two-car capacity or a full workshop with vehicle storage, these sizes deliver. Custom widths and lengths are available if your property or needs don’t match standard dimensions.
Key Factors Beyond Just “What Fits”
- What you own now vs. what you’ll own in 3–5 years Most people underestimate future needs. If you’re already tight on space in the garage, size up.
- Door and access requirements A standard double door works for most storage. Riding mowers and larger equipment often need a wider or taller door opening. Think about how you’ll move items in and out.
- Interior layout Shelving, lofts, workbenches, and windows change how usable the space feels. A well-planned 10×12 can outperform a poorly organized 12×16.
- Property constraints Measure the available space carefully, including setbacks from property lines, septic systems, and overhead clearance for delivery. Also consider how the shed will look next to your house.
- Permits and local rules Many townships start requiring permits (or have stricter rules) once you cross certain size thresholds, often around 120–200 square feet. We can help you understand the requirements in your area.
- Future flexibility Choosing a slightly larger footprint or a style that accepts future upgrades (electric, loft, porch, metal roof) often pays off.
How Infinite Sheds Makes Sizing Easier
We build custom sizes every day, not just standard ones. Whether you need something that fits a tight side yard or a larger workshop with specific door placements, we can design it. Our lower-overhead model also means you often get more building for the same money compared with traditional showrooms.
Many customers start by telling us:
- What they plan to store or do in the shed
- Approximate dimensions of the available space
- Whether they want a loft, electric, specific door sizes, or a certain roof style
From there we can recommend the best size and configuration.
Ready to Narrow It Down?
If you’re still unsure between two sizes, the safer bet is usually the larger one — as long as your property and budget allow it. Running out of space is far more common than having “too much” shed.
