What Can You Fit in a 12x20 Shed?

A 12x20 shed gives you 240 square feet of floor space. That is one of the most popular sizes we sell at Banner Buildings, and there is a good reason for it: it is large enough to handle serious storage or a working space, but it fits on most residential lots without dominating the yard.

If you are trying to decide whether a 12x20 is the right size for your situation, here is a practical breakdown of what that space can actually hold.

Lawn Equipment and Yard Storage

A 12x20 comfortably handles a full set of lawn and yard equipment. A standard zero-turn or riding mower typically runs 60 to 72 inches wide and 60 to 70 inches long. That mower fits through a 12-foot-wide shed with room on both sides, and you still have significant floor space left over once it is parked inside.

Beyond the mower, a 12x20 can also hold a push mower or walk-behind, a lawn tractor attachment or two, a broadcast spreader, bags of fertilizer and seed, a garden cart, shovels, rakes, and the general collection of yard supplies that accumulates over time. You can fit all of that and still have walkable floor space if you use the walls efficiently with shelving or hooks.

For most homeowners with a standard yard, a 12x20 is enough lawn equipment storage with room to spare. If you have acreage and a larger equipment collection -- multiple mowers, a tractor, implements -- step up to a 12x24 or larger.

Vehicle Storage

Whether a 12x20 works for vehicle storage depends on the vehicle and the door configuration.

A standard compact car is typically about 70 inches wide and 165 to 175 inches long. A 12x20 interior is 144 inches wide and 240 inches long, so the dimensions technically work. But "technically fits" is not the same as "easy to use." Getting a car in and out of a 12x20 requires careful maneuvering, and you will not have much room for anything else alongside it.

A full-size truck or SUV is a tighter story. Full-size trucks run 80 inches wide or more in many cases. You can get one into a 12-foot-wide shed, but clearance will be tight at the doors. For comfortable vehicle storage, a 14-foot-wide building is a better fit for a full-size truck.

A 12x20 works well for storing an ATV, golf cart, small utility trailer, or motorcycle with room left over. For a single compact car or small SUV, it is workable if that is the primary use. For a truck or if you want to work on the vehicle inside, go wider.

Door choice also matters significantly for vehicle storage. A roll-up door gives you a wide, unobstructed opening and is generally the better choice if you are driving anything in. Double walk doors are hinged and require clearance to swing open, which complicates entry. If vehicle access is a priority, specify a roll-up door when you order.

Workshop Use

A 12x20 is a legitimate workshop space. It is not cramped. You can set up a workbench along one wall -- an 8-foot bench takes up a manageable portion of the 20-foot length -- and still have clear floor space for standing and moving around while you work.

Common workshop configurations for a 12x20 include a workbench along the back wall, tool storage or pegboard on the side walls, and open floor space in the center for the project at hand. If you want a table saw or other stationary tool, you can place it in the center and still have room to feed material through it.

For serious woodworking or mechanic work, a 12x24 gives you noticeably more breathing room. But for most hobby-level work -- carpentry, mechanical work on small equipment, a general handyman shop -- a 12x20 is enough to work comfortably.

Shelving and Organization

One of the most common ways people underuse a shed is by not using the walls. The floor footprint of a 12x20 is 240 square feet, but the usable storage increases significantly when you add shelving along the walls. Standard wire shelving or simple wood shelves on the side walls can add 40 to 60 linear feet of shelf space without touching the floor area.

A few practical suggestions for organizing a 12x20: put the large equipment (mowers, vehicles) on the floor, use upper wall space for seasonal items and things you do not access often, and keep the area near the door clear for frequently used tools and supplies. Overhead storage on ceiling joists or loft shelving can also help if height allows.

How a 12x20 Compares to Nearby Sizes

A 10x20 gives you 200 square feet -- the same length, but two feet narrower. That difference matters more than it sounds. The narrower width limits door options, makes vehicle access tighter, and reduces how much you can fit side by side. If you are deciding between a 10x20 and a 12x20, the 12x20 is usually worth the difference in price.

A 12x16 gives you 192 square feet. It works well for lawn equipment storage but is noticeably tighter for workshop use or vehicle storage. If a 12x20 is close to your budget limit, a 12x16 is a reasonable step down. If you can swing the 12x20, you will find the extra 48 square feet useful.
