Ceiling Height Needed for a Murphy Bed

Why ceiling height matters for a Murphy bed

A Murphy bed folds into a cabinet when not in use, but when you pull it down, it takes up vertical space. The bed's frame, mattress, and any attached desk or shelving all need room to swing into place. If the ceiling is too low, the bed may not open fully, or the mattress may press against the ceiling, which can damage both.

The key measurement is the bed's height when it is open, not the cabinet height. For a vertical bed, the open height is the distance from the floor to the top of the mattress. For a horizontal bed, the open height is the distance from the floor to the top of the bed's side rail. The maker's listing usually states this dimension, so read it carefully. To compare models, see our guide to the best Murphy beds.

Vertical vs. horizontal: how fold direction changes clearance

Vertical Murphy beds fold up and down, so the bed's length runs from floor to ceiling when open. This means the ceiling height must be at least the bed's open height, plus a little extra for the mattress and bedding. Horizontal beds fold sideways, so the bed's width runs from floor to ceiling. They need less vertical clearance but more wall width.

If you have a low ceiling, a horizontal bed might be a better fit, but it will take up more wall space. For a room with standard ceiling height, a vertical bed is usually fine. The trade-off is between vertical clearance and horizontal wall space, so measure both before you decide. Learn more about the differences in our vertical vs. horizontal guide.

How to measure your room for ceiling clearance

To find out if a Murphy bed will fit, measure the ceiling height at the spot where the bed will be installed. Use a tape measure from the floor to the ceiling, and write down the number. Do this at the head and foot of the bed's intended position, because floors and ceilings are not always level.

Then, look at the bed's stated dimensions when open. The maker's listing should give the height of the bed in the open position. Compare that to your ceiling height. If the bed's open height is less than your ceiling height, it should fit. If it is close, consider the mattress thickness, because a thicker mattress adds height.

Also measure the width of the wall where the bed will go. For a horizontal bed, the bed's width when open is the critical dimension. For a vertical bed, the width is the cabinet width, which is usually narrower. Write down both measurements and keep them with you when you shop. For a step-by-step approach, see our room measuring guide.

How mattress thickness affects ceiling clearance

The mattress is part of the open height. A thicker mattress raises the top of the bed, so it needs more ceiling clearance. Murphy beds often use foam mattresses that are 8 to 12 inches thick, but the exact thickness depends on the model. The maker's listing usually states the recommended mattress thickness or includes a mattress with the bed.

If you plan to buy a mattress separately, check the bed's maximum mattress thickness. Some makers specify a limit, and going over it can prevent the bed from closing or opening properly. The mattress thickness is part of the bed's open height, so add it to the frame height when you compare to your ceiling. Read more about mattress thickness.

Special cases: desk beds, cabinet beds, and low ceilings

Desk beds have a desk that folds down with the bed. The desk adds height to the open position, so the ceiling clearance is often greater. For example, a queen desk bed from Wilding Wallbeds has a height of 75 inches when open, which is taller than a standard queen wall bed. Check the listing for the exact open height.

Cabinet beds, like those from Night and Day Furniture, are freestanding and fold out from a cabinet. They have a lower profile, so they may fit under lower ceilings. The cabinet height is usually around 41 inches, but the open height is what matters. Measure the open height, not the cabinet height. See our cabinet bed guide for options.

If you have a low ceiling, look for a horizontal bed or a cabinet bed. These designs need less vertical clearance. Also, consider a bed with a thinner mattress, which reduces the open height. Always follow the maker's instructions for installation and clearance.

What to check in the listing before you buy

Before you buy, read the listing's dimensions section. Look for the bed's height when open, not just the cabinet height. The listing may also state the maximum mattress thickness and the recommended ceiling height. If the listing does not give these numbers, contact the maker or seller.

Also check the bed's width and depth when open, because these affect how much floor space you need. For a horizontal bed, the width is the critical dimension. For a vertical bed, the depth is the distance the bed extends into the room. Make sure you have enough space in front of the bed for it to open fully.

Finally, consider the room's layout. A ceiling light or fan can reduce the effective clearance. Measure from the floor to the lowest point of any obstruction, not just the ceiling. This gives you the true clearance for the bed. For more on fitting a bed into a room, see our full size Murphy bed guide.

Questions

What is the minimum ceiling height for a Murphy bed?

There is no single minimum because it depends on the bed's open height. A vertical bed needs the ceiling to be at least as high as the bed's open height. A horizontal bed needs less vertical clearance. Check the maker's dimensions for the specific model.

Do horizontal Murphy beds need less ceiling height?

Yes, horizontal beds fold sideways, so the bed's width runs from floor to ceiling. This means they need less vertical clearance than vertical beds, but they require more wall width.

Does the mattress thickness affect ceiling clearance?

Yes, a thicker mattress raises the top of the bed when open. The mattress thickness is part of the open height, so add it to the frame height when comparing to your ceiling.

Can I install a Murphy bed under a sloped ceiling?

It depends on the slope and the bed's open height. Measure the lowest point of the ceiling where the bed will be. If the bed's open height is less than that, it may fit. Always check the maker's instructions.

What if the listing does not state the open height?

Contact the maker or seller for the open height. Do not guess, because the bed may not fit. The open height is a critical dimension for installation.
