DIY Floating Shelves Cut List and Plan
Build floating shelves: a plywood cut list for the shelf box and hidden cleat, sizes, and how to mount them strong. A clean, modern shelf project.
Research Lens
How can a personal builder use CutList to finish diy floating shelves cut list and plan with fewer mistakes?
The hobby workflow is strongest when the app is used as a planning checkpoint: define the project, enter accurate stock and parts, generate a visual layout, then use cost, waste, grain, kerf, PDF export, project history, and offline access to control the real cutting session.

How Floating Shelves Work
A floating shelf hides its support, usually a cleat screwed to the wall studs, inside a hollow shelf box that slides over it. The look is clean and modern with no visible brackets. The build is simple: a hidden cleat plus a wrap-around plywood box. The cut list covers both parts.
The Hidden Cleat
The cleat is a solid-wood or plywood strip fastened firmly to the wall studs; it carries all the load. It must hit studs, not just drywall, for any real weight. Size the cleat to fit snugly inside the shelf box. The strength of a floating shelf is entirely in the cleat and its fasteners.
The Shelf Box
The visible shelf is a hollow box: a top, a bottom, a front edge, and short end caps, built to slide over the cleat. Plywood with banded or solid-wood front edges looks clean. Keep the box depth and the cleat depth matched so the shelf sits level and tight when pushed home.
A Typical Cut List
For one 30-inch floating shelf in 3/4-inch plywood: a top and bottom at shelf depth by 30 inches, a front edge, two end caps, plus a solid-wood cleat sized to fit inside. Adjust the length and depth to your space, and band the front edge for a finished look. Multiply for several shelves.
Mounting Strong
Find and mark the studs, fasten the cleat level with appropriate screws into framing, then slide the box on and secure it to the cleat from beneath or the back. Keep loads sensible for the stud spacing and fasteners. A well-anchored cleat is what makes a floating shelf safe and solid.

| Part | Qty | Material | Note |
|---|---|---|---|
| Top / bottom | 2 | 3/4 in plywood | Shelf depth x length |
| Front edge | 1 | Plywood/solid | Banded or solid |
| End cap | 2 | 3/4 in plywood | Close the box |

Field Checklist
- Build a hidden cleat plus a wrap-around box.
- Anchor the cleat into wall studs, not drywall.
- Match the box depth to the cleat depth.
- Band or edge the visible front for a clean look.
- Secure the box to the cleat once mounted.
FAQ
Common questions
How do floating shelves stay up?
A cleat fastened to the wall studs carries the load, hidden inside a hollow shelf box that slides over it, so no brackets show.
What plywood for floating shelves?
3/4-inch plywood for the box, with a banded or solid-wood front edge. The hidden cleat is solid wood or plywood anchored to studs.
How much weight can a floating shelf hold?
It depends on the cleat, fasteners, and stud spacing. Anchor the cleat into studs and keep loads sensible; the cleat is the strength.
How deep should a floating shelf be?
Match the box depth to the cleat and your needs, commonly 6-10 inches. Match cleat and box depth so the shelf sits level and tight.
Can I build floating shelves from one sheet?
Several short shelves can come from one sheet. Lay out the tops, bottoms, edges, and caps with a calculator to confirm.
