10x18 Shed Material List

Quick Answer

A 10x18 gable shed with 8 ft walls, 16 inch on center framing, 4/12 roof pitch, pressure treated floor framing, OSB or plywood sheathing, a basic single or double door, and gravel foundation is a mid-large structure commonly used for riding mower storage, workshop space, motorcycles, or garage overflow. The 10 ft width keeps framing manageable, while the 18 ft length significantly increases material quantities.

Full Material List

Quantities assume 8 ft wall height, 16 inch on center spacing, and a standard door opening.

Floor Framing

A 10 ft span benefits from stronger joists, especially for equipment loads.

Gravel Base

• 4.5 to 6.5 cubic yards of compacted 3/4 inch crushed gravel

Floor Frame (Pressure Treated)

Perimeter

• 2x8x18 PT – 2 (long rim joists)
• 2x8x10 PT – 2 (end band joists)

If 18 ft boards are unavailable, splice sections over blocking.

Floor Joists (16 inch OC across 10 ft span)

• 2x8x10 PT – 13 to 14

Floor Sheathing

• 3/4 inch tongue and groove plywood or OSB – 6 sheets

Fasteners

• Exterior-rated screws or galvanized framing nails
• Joist hangers recommended

Wall Framing

Framed 16 inch on center.

• 2x4x8 studs
• 95 to 105 total
• Includes perimeter walls
• Door framing
• Waste allowance

Plates

• 2x4x18 – 6 (long walls, double top plates + bottom plates)
• 2x4x10 – 6 (end walls)

Splicing shorter boards is common for long walls.

Door Framing

• 2x6x8 – 2 (header material)
• 1/2 inch plywood spacer
• Jack and king studs included in stud count

Roof Framing

A 10 ft span typically uses 2x6 rafters across a long ridge.

Rafters (4/12 pitch, 16 inch OC)

• 2x6x14 – 28 to 30

Approximately 14 to 15 rafter pairs.

Ridge Board

• 2x8x18 – 1

Collar Ties or Ceiling Ties

• 2x4x10 – 14 to 15

Sheathing

Long walls increase panel usage.

Wall Sheathing

• 7/16 inch OSB or plywood – 16 to 18 sheets

Panel siding may eliminate separate sheathing.

Roof Sheathing

• 7/16 inch OSB or plywood – 10 to 11 sheets

Siding

Panel siding is most common for sheds of this size.

T1-11 or LP SmartSide Panels

• 16 to 18 sheets

Alternative siding systems require additional trim components.

Roofing

Underlayment

• 2 rolls synthetic underlayment

Drip Edge

• 8 to 10 pieces (10 ft lengths)

Shingles

• Approximately 2.25 to 2.5 squares
• 8 to 10 bundles depending on waste

Roofing Nails

• 7 to 8 lb box

Hardware and Fasteners

• 16d framing nails or structural screws

• Exterior construction screws
• Construction adhesive (4 to 5 tubes)
• Hurricane ties recommended
• 2 to 3 heavy-duty door hinges
• Exterior latch or handle
• Lockset or padlock hardware
• Flashing for door header

Step-by-Step Build Overview

High-level sequence only.

• Prepare and compact gravel base across full footprint.
• Build pressure treated floor frame and verify square.
• Install floor sheathing.
• Frame walls on the ground including door opening.
• Raise walls, plumb, and brace securely.
• Install double top plates tying walls together.
• Install ridge board and rafters.
• Add collar ties or ceiling ties.
• Install roof sheathing.
• Install drip edge and underlayment.
• Install shingles.
• Install wall sheathing if required.
• Install siding.
• Build and hang door.
• Install trim and hardware.
• Check square frequently to prevent alignment issues over long distances.

Common Mistakes

• Losing square across long walls. Small errors compound over distance.
• Using undersized floor joists for heavy loads. Causes flex or sagging.
• Poor base preparation. Leads to uneven settling.
• Underestimating materials. Causes delays and additional trips.
• Weak door framing. Leads to sagging or binding doors.
• Inadequate wall bracing during construction. Long walls can shift before roof installation.
