Measuring Your Space

Measuring is the most important step in getting the correct size mattress for the correct size bed

When you measure a room for a Murphy bed consider the height, width and depth of the bed when it is in the closed and open positions. When the bed is open – look at the projection – this is the length from the wall to the edge of the bed frame. Certainly, these dimensions will provide you with a better understanding of how the bed will fit into your space.


Dimensions, including the height, width, depth (when closed) and projection from the wall (when open), will allow you to easily see how your Murphy bed and side cabinets if you choose them, will fit on a wall in your space.

If the size of the room allows, you will want to keep some space on either side of the bed for you to be able to move around the bed. In addition, you may want to add side cabinets for storage.

Measuring Terminology

  • Height – your ceiling height must be at least 2 1/2″ taller than the height of the wall bed
  • Width is measured from both sides of the outside of the molding to the outside of the molding
  • Depth is the dimension from the wall to the front of the face of the bed, in the closed position
  • Projection is the dimension from the wall to the outside of the bed frame, in the open position

Bed Styles

Vertical Wall Bed
Basically, this bed resembles a normal bed when it is open. It allows you to enter the bed from either side. This style of Murphy bed works best in spaces with enough ceiling height for the bed cabinet. It is very important to think about ceiling fans. For instance, when pulling down the bed, you need to be sure you have enough ceiling space. Above all, you must avoid contact with the fan and lighting.

Horizontal Wall Bed
This style of bed is best for rooms with low ceilings. Therefore, you do not have to worry about ceiling fans and lights. The bed frame is side-mounted.
