Plywood Platform Bed: Cut List and Plan
Build a plywood platform bed: a cut list for the platform, supports, and frame by mattress size, plus storage options. A clean, sturdy DIY bed.
Research Lens
How can a personal builder use CutList to finish plywood platform bed: 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.
Decision Metrics
A Simple, Sturdy Bed
A platform bed is a flat, supported surface for a mattress, no box spring needed. Plywood makes a clean, strong platform, and the build is straightforward: a supported platform on a frame or legs. It is a great project for a first piece of plywood furniture, with optional storage underneath.
Size to the Mattress
Start from the mattress size: a queen is about 60 by 80 inches, a king about 76 by 80, a full about 54 by 75, a twin about 38 by 75. The platform should match or slightly exceed the mattress, with the frame sized accordingly. Confirm your mattress dimensions before cutting, as sizes vary.
Platform and Support
The platform is one or more plywood panels supported so they cannot sag under load. Center support rails and legs (or a perimeter frame with cross slats) carry the weight. A solid, well-supported platform is what keeps the bed quiet and stable; under-support leads to sagging and creaks.
A Typical Cut List
For a queen platform in 3/4-inch plywood: the platform panel(s) at about 60 by 80 inches (often split for handling), perimeter frame pieces, center support rails, and legs. Splitting a large platform into two panels makes it easier to move and cut. Add storage boxes underneath if desired.
Adding Storage
The space under a platform bed suits drawers or open cubbies. Build storage boxes into the frame, or add pull-out drawers on the open sides. Plan these as a separate cut-list section. Under-bed storage turns dead space into a real benefit, especially in small rooms.
Compare
Platform bed by mattress
| Size | Mattress (in) | Platform | Note |
|---|---|---|---|
| Twin | 38 x 75 | Single panel | Light |
| Full | 54 x 75 | May split | Center support |
| Queen | 60 x 80 | Split panels | Center support |
| King | 76 x 80 | Split panels | Extra support |
Field Checklist
- Size the platform to the mattress.
- Support the platform so it cannot sag.
- Split a large platform for easier handling.
- Use center rails and legs or a frame with slats.
- Add under-bed drawers or cubbies if wanted.
FAQ
Common questions
What plywood for a platform bed?
3/4-inch plywood for the platform and frame, well supported with center rails and legs so it carries the mattress and sleeper without sagging.
How big is a queen platform bed?
About 60 by 80 inches to match a queen mattress, often built as two panels for easier handling. Confirm your mattress size first.
Do platform beds need a box spring?
No. A solid, supported plywood platform replaces the box spring, which is part of the appeal of a platform bed.
How do I keep a platform bed from sagging?
Support the platform with center rails and legs or a perimeter frame with cross slats, so the panel cannot deflect under load.
Can I add storage under a platform bed?
Yes. Build drawers or cubbies into the frame, planned as a separate cut-list section, to use the under-bed space.
