What fits in a 12x24 shed?
A 12x24 shed has 288 sq ft of floor. Drawn to scale with a clear aisle, it holds a lawn tractor, a zero-turn, a snow blower, a wheelbarrow, a workbench, 3 shelving units, and it can take a 42 in lawn tractor if the door is at least 5 ft wide. Kits this size run $9,486 to $9,486 on Amazon.
A 12x24 is garage territory at 288 sq ft. It holds two machines and a workshop, but it is past every common permit exemption and needs a foundation you plan properly. Below, two common loads are drawn to scale on a 12x24 floor, so you can see what actually fits once you leave yourself a way in.

How many of each item fit in a 12x24?
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) | 5 |
| Zero-turn mower (48 to 54 in deck) | 5 |
| Push mower (handle folded) | 12+ |
| Two-stage snow blower | 12+ |
| Wheelbarrow | 12+ |
| Adult bike (on the floor) | 12+ |
| Trash or recycling can (96 gal) | 12+ |
| Gas grill (off-season) | 12+ |
| Shelving unit (18 x 48 in) | 12+ |
| Workbench (2 x 6 ft) | 12+ |
| Kayak (floor) | 8 |
Is a 12x24 shed big enough for a riding mower?
Yes. A 42 in lawn tractor (about 4.5 x 6 ft parked) fits in a 12x24 with room to walk past it. The real test is the door: you need at least 5 ft of clear opening, so check the kit's door spec before the footprint.
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 12x24 shed need?
Most resin and steel kits want a flat, level, well-drained base a little larger than the shed. For a 12x24, that is a 14 x 26 ft gravel pad: about 6.9 tons of crushed stone at 4 in deep, or 10.4 tons at 6 in. A 4 in concrete slab takes 3.91 cubic yards (177 bags of 80 lb mix), and a paver base takes about 171 pavers at 16 in. Full quantities and costs are on the 12x24 shed foundation page.
Does a 12x24 shed need a permit?
At 288 sq ft a 12x24 is over every common exemption, so plan on a permit. 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 12x24 shed?
A 12x24 shed is 288 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 12x24 shed?
Yes. A 42 in lawn tractor (about 4.5 x 6 ft parked) fits in a 12x24 with room to walk past it. The real test is the door: you need at least 5 ft of clear opening, so check the kit's door spec before the footprint.
Do I need a permit for a 12x24 shed?
At 288 sq ft a 12x24 is over every common exemption, so plan on a permit. 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 12x24 shed?
With a 1 ft border on every side, a 12x24 shed sits on a 14 x 26 ft pad. At 4 in deep that is 4.94 cubic yards, about 6.9 tons of crushed stone including 10 percent for compaction. At 6 in, for soft or wet ground, order 10.4 tons. Lay weed fabric first and frame the pad with treated timber.
