Cabinet Murphy Bed Sizes: Queen, Full, Twin, and More

Cabinet Murphy beds are most commonly sold in queen size, with several product lines offering no other mattress option at all.

If you’re shopping for a cabinet Murphy bed, the size question has a faster answer than the general wall-bed market suggests. While traditional wall-mounted Murphy beds come in twin, full, queen, and king, the freestanding cabinet style that folds into a furniture piece is far more likely to be queen-only. Before you fall for a gorgeous cabinet design, confirm which mattress size that specific line actually supports — not every brand builds every frame in every size.

Are Cabinet Murphy Beds Available Outside Queen Size?

Some sellers do offer full, twin, and king wall-bed systems, but several popular cabinet bed product lines are queen-only. So the honest answer depends on the brand you choose, not on the cabinet style in general.

The queen preference makes practical sense. A queen mattress balances sleeping room for two against the cabinet’s footprint — wide enough to be comfortable, compact enough to still look like furniture when folded shut. For a guest room or a studio, that trade-off is exactly why cabinet beds exist.

What Are The Standard Cabinet Bed Dimensions?

Dimensions vary significantly by manufacturer, so treat any single number as a starting point, not a universal spec.

Both are real products; the gap between them is normal.

For comparison, general size charts for Murphy beds — which include wall-mounted units, not just cabinet styles — list standard vertical dimensions as roughly:

• Twin: 82–87″ high x 43–46″ wide x 16–21″ deep, with an 80–82″ projection
• Full: 82–87″ high x 57–61″ wide x 16–21″ deep, with an 80–82″ projection
• Queen: 87–89″ high x 64–68″ wide x 16–21″ deep, with an 85–90″ projection
• King: 89–92″ high x 84–86″ wide x 16–21″ deep, with an 85–90″ projection

Another trusted brochure, this one for bi-fold bed cabinets, lists twin at 45″ W x 85″ H, full at 60″ W x 85″ H, queen at 66″ W x 90″ H, and king at 84″ W x 90″ H, all with 15″ or 20″ depth options.

How Much Floor Space Does A Queen Cabinet Bed Need?

The single biggest mistake buyers make is treating the mattress size as the whole footprint. One trusted source explicitly notes that a Murphy bed’s size includes the mattress and the surrounding larger cabinet. A queen mattress measures 60″ wide by 80″ long, but a queen cabinet bed can run 64–77″ wide and project 83–90″ into the room when open.

That extra clearance matters in tight spaces. Measure the room’s clear wall space, not just the corner where the mattress will sit. You also need room for the bed to fold down fully — the projection is the number that tells you whether the open bed will block a door, a closet, or a desk.

Installation And Compatibility Cautions

Two caveats separate a smooth installation from a frustrating one. First, cabinet size and mattress size are not interchangeable across brands. Published dimensions vary by manufacturer and by vertical versus horizontal orientation, so the frame built for one brand’s queen mattress may not fit another’s.

Second, even freestanding-looking cabinet beds need proper anchoring. Skip that step and the bed becomes a tipping hazard — the wall is doing the real work.
