10x12 Sheds

10x12 storage shed size and floor space

A 10x12 storage shed has a nominal footprint of 120 square feet. Listed widths on this page run from 113.7 to 145.9 inches and depths from 113 to 145.9 inches, so the overall size varies by design.

Heights run from 75.3 to 87 inches, which gives enough headroom for shelving and tall tools. Check each listing for exact dimensions before you plan the base, and leave a clear strip around the shed for door swing and for walking around to clear the roof.

10x12 metal shed materials and finishes

Every 10x12 shed here is metal, and select models name steel, iron or aluminum. Gray is the most common color, with brown, black and white also available.

Aluminum resists rust as a material. Steel and iron do best when the finish is kept intact, so touch up scratches early and keep the base dry. Choose a color that suits the yard, since a darker finish blends into a fence line while white stands out.

10x12 shed with floor, windows and lockable doors

Features vary across the 10x12 sheds on this page. A few are a 10x12 shed with floor, some have windows for daylight, and some have lockable doors. Apex roofs on select models give the center extra height.

Compare the features line on each listing, since a floor still needs a level base underneath.

10x12 shed kit assembly and base

A 10x12 shed kit is assembled on site from panels and hardware. Plan for at least two people and a full day, and prepare a level, firm, well-drained base such as compacted gravel, pavers or a slab before you start.

Add shelving along the walls and keep the roof clear of leaves so water runs off. Lay out the hardware by step before you begin, and keep the doors and roof panels for last so the frame stays square while you work.
