10x12 Shed Material List
The complete, pre-calculated material list for a 10×12 gable-roof shed with 8-ft walls — every stud, sheet, and bundle you need to buy.
Last updated: May 2026
The 10×12 is the most popular shed size sold in the U.S., and for good reason: 120 square feet handles all-around storage — mower, bikes, seasonal furniture, and garden tools — with room to walk in and grab what you need. The list below covers a 10×12 footprint (120 sq ft) and assumes 8-foot walls, a gable roof at a 6/12 pitch, walls framed 16 inches on center, and a framed plywood floor. Every quantity is computed with the same formulas as our shed material calculator — if you want to adjust dimensions or roof style, run your own numbers there.

How Much Lumber for a 10x12 Shed?
A 10×12 shed with 16-inch on-center walls needs about 37 wall studs plus 17 eight-foot 2×4s for the top and bottom plates. The gable roof takes 14 2×6 rafters at 24-inch spacing, and the floor frame uses 10 2×6 joists at 16 inches on center. For sheet goods, plan on 11 sheets of OSB for wall sheathing, 5 sheets for the 148 sq ft roof deck (including overhang), and 4 sheets of 3/4-inch plywood for the floor — 20 sheets in total — plus 11 sheets of T1-11 siding and 5 bundles of shingles. Buy two or three extra studs for blocking and door framing, and cull any badly crowned boards for cut-up pieces.
Foundation for a 10x12 Shed
A gravel pad should extend 12 inches beyond the shed on all sides, so a 10×12 shed needs a 12×14 gravel pad. At 4 to 6 inches deep, that works out to about 2.5 cubic yards of compacted 3/4-inch crushed stone over landscape fabric — fine-tune the gravel quantity here. If you would rather pour a concrete slab, a 10x12 slab at 4 inches thick takes about 1.5 cubic yards of concrete — roughly 67 80-lb bags, which is well past the point where ready-mix delivery makes more sense than mixing by hand. Estimate the concrete for a slab here.
Estimated Total Cost
Expect DIY materials for a 10x12 shed to run $1,412 to $3,400. The low end assumes basic framing lumber, OSB sheathing, and 3-tab shingles; the high end reflects plywood sheathing, architectural shingles, and premium siding. That total does not include the foundation, paint or stain, a ramp, or shelving. For a full comparison of DIY builds against shed kits and professional installation, see our shed cost guide.
Frequently Asked Questions
Materials for a 10x12 shed with 8-foot walls, a 6/12 gable roof, and a framed plywood floor run about $1,412 to $3,400. The low end reflects basic framing lumber, OSB sheathing, and 3-tab shingles; the high end reflects plywood sheathing, architectural shingles, and premium T1-11 siding. Foundation materials, paint, and interior shelving are extra, and hiring a contractor to build it adds labor on top of materials.
A 10x12 shed with 8-foot walls and a 6/12 gable roof needs about 20 sheets of 4x8 sheet goods in total: 11 sheets for wall sheathing, 5 sheets for the roof deck, and 4 sheets of 3/4-inch plywood for the floor. Use OSB for walls and roof to save money, but stick with plywood rated for flooring on the deck.
