What fits in a 4x10 shed?
A 4x10 shed has 40 sq ft of floor. Drawn to scale with a clear aisle, it holds a push mower, a wheelbarrow, a shelving unit, and it is too small for a lawn tractor. Kits this size run $325 to $989 on Amazon.
A 4x10 is a compact garden shed. At 40 sq ft it holds a mower and hand tools comfortably, but it fills quickly once bikes or a wheelbarrow go in. Below, two common loads are drawn to scale on a 4x10 floor, so you can see what actually fits once you leave yourself a way in.

How many of each item fit in a 4x10?
Each row is that item on its own, packed flat on the floor with a clear aisle kept from the door. Hanging bikes and stacking bins beat these numbers; parking a mower across the aisle does not count.
| Item | Fits |
|---|---|
| Riding mower / lawn tractor (42 in deck) | none |
| Zero-turn mower (48 to 54 in deck) | none |
| Push mower (handle folded) | 4 |
| Two-stage snow blower | 2 |
| Wheelbarrow | 2 |
| Adult bike (on the floor) | 2 |
| Trash or recycling can (96 gal) | 4 |
| Gas grill (off-season) | 4 |
| Shelving unit (18 x 48 in) | 4 |
| Workbench (2 x 6 ft) | 2 |
| Kayak (floor) | 1 |
Is a 4x10 shed big enough for a riding mower?
No. A 42 in lawn tractor parks at about 4.5 x 6 ft and needs a clear aisle to drive in and a door at least 5 ft wide. A 4x10 cannot give it both. For a ride-on mower, look at an 8x10 with double doors or larger.
Not sure about your own mix of gear? The shed size calculator adds up every item's footprint, multiplies by 1.5 for aisles and reach, and names the smallest standard size that works.

What foundation does a 4x10 shed need?
Most resin and steel kits want a flat, level, well-drained base a little larger than the shed. For a 4x10, that is a 6 x 12 ft gravel pad: about 1.4 tons of crushed stone at 4 in deep, or 2.1 tons at 6 in. A 4 in concrete slab takes 0.54 cubic yards (25 bags of 80 lb mix), and a paver base takes about 24 pavers at 16 in. Full quantities and costs are on the 4x10 shed foundation page.
Does a 4x10 shed need a permit?
At 40 sq ft a 4x10 is exempt by size under all three common thresholds. Height limits (often 10 to 12 ft at the peak), setbacks of 3 to 5 ft from property lines and HOA covenants apply at any size, and wiring always needs an electrical permit. Run your numbers through the permit size checker, then check your local code.

Frequently asked questions
How many square feet is a 4x10 shed?
A 4x10 shed is 40 square feet of nominal floor area. Usable floor is a little less, because kit dimensions are usually measured at the roof or outside the walls, and resin and steel walls take up floor on every side. Compare the interior dimensions in the kit's spec sheet before you commit, especially if a mower or workbench needs every inch.
Can a riding mower fit in a 4x10 shed?
No. A 42 in lawn tractor parks at about 4.5 x 6 ft and needs a clear aisle to drive in and a door at least 5 ft wide. A 4x10 cannot give it both. For a ride-on mower, look at an 8x10 with double doors or larger.
Do I need a permit for a 4x10 shed?
At 40 sq ft a 4x10 is exempt by size under all three common thresholds. The International Residential Code exempts one-story storage sheds up to 200 sq ft, but many towns lower that to 120 or 100 sq ft, and setbacks, easements, HOA rules and any electrical work apply at every size. Check your local code before you order the kit.
How much gravel do I need for a 4x10 shed?
With a 1 ft border on every side, a 4x10 shed sits on a 6 x 12 ft pad. At 4 in deep that is 0.98 cubic yards, about 1.4 tons of crushed stone including 10 percent for compaction. At 6 in, for soft or wet ground, order 2.1 tons. Lay weed fabric first and frame the pad with treated timber.
How much does a 4x10 shed cost?
The 5 4x10 kits in our catalog run from $325 to $989. Add about $122 for a gravel pad, $72 or so for anchors, and $150 or more for shelving, a light and a lock. Prices change often, so check the live price before budgeting.
