Shed size · 128 sq ft
What fits in an 8x16 shed?
An 8x16 shed has 128 sq ft of floor. Drawn to scale with a clear aisle, it holds a lawn tractor, a push mower, a wheelbarrow, 2 shelving units, and it can take a 42 in lawn tractor if the door is at least 5 ft wide. Kits this size cost about $2,327 in resin or $672 in steel at median prices.
An 8x16 is where a shed starts working as a real outbuilding. 128 sq ft is enough for a lawn tractor with room to walk around it, or bikes plus a small workbench. Below, two common loads are drawn to scale on an 8x16 floor, so you can see what actually fits once you leave yourself a way in.

How many of each item fit in an 8x16?
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) | 3 |
| Zero-turn mower (48 to 54 in deck) | 3 |
| Push mower (handle folded) | 8 |
| Two-stage snow blower | 6 |
| Wheelbarrow | 6 |
| Adult bike (on the floor) | 8 |
| Trash or recycling can (96 gal) | 12+ |
| Gas grill (off-season) | 8 |
| Shelving unit (18 x 48 in) | 10 |
| Workbench (2 x 6 ft) | 8 |
| Kayak (floor) | none |
Is an 8x16 shed big enough for a riding mower?
Yes. A 42 in lawn tractor (about 4.5 x 6 ft parked) fits in an 8x16 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 an 8x16 shed need?
Most resin and steel kits want a flat, level, well-drained base a little larger than the shed. For an 8x16, that is a 10 x 18 ft gravel pad: about 3.4 tons of crushed stone at 4 in deep, or 5.1 tons at 6 in. A 4 in concrete slab takes 1.74 cubic yards (79 bags of 80 lb mix), and a paver base takes about 76 pavers at 16 in. Full quantities and costs are on the 8x16 shed foundation page.
Does an 8x16 shed need a permit?
At 128 sq ft an 8x16 is exempt only where the 200 sq ft IRC exemption is adopted unamended. 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 an 8x16 shed?
An 8x16 shed is 128 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 an 8x16 shed?
Yes. A 42 in lawn tractor (about 4.5 x 6 ft parked) fits in an 8x16 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 an 8x16 shed?
At 128 sq ft an 8x16 is exempt only where the 200 sq ft IRC exemption is adopted unamended. 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 an 8x16 shed?
With a 1 ft border on every side, an 8x16 shed sits on a 10 x 18 ft pad. At 4 in deep that is 2.44 cubic yards, about 3.4 tons of crushed stone including 10 percent for compaction. At 6 in, for soft or wet ground, order 5.1 tons. Lay weed fabric first and frame the pad with treated timber.
How much does an 8x16 shed cost?
No kit in our catalog is exactly 8x16. At the median kit prices we measured, 128 sq ft costs about $672 in steel, $2,327 in resin and $2,667 as a wood kit, before a foundation of about $214 in gravel.
