Murphy Bed Dimensions: What Are The Standard Sizes?

Last Updated on September 17, 2023 by Kimberly Crawford

Murphy beds, named after their inventor William Lawrence Murphy, have been around since the late 19th century. The idea came to Murphy when he was living in a one-room apartment in San Francisco and needed to make better use of his limited space.

His innovative solution was a bed that could be folded up into the wall when not in use, freeing up valuable floor space. Murphy’s idea took off, and the Murphy bed became a popular feature in apartments, hotels, and homes around the world.

A Murphy bed, also known as a wall bed or pull-down bed, is a bed that is hinged at one end so it can be folded up vertically against a wall or inside a closet or cabinet. When folded up, the bed disappears to leave a spacious room for day use. This makes it a fantastic space-saving solution, especially for small homes or multi-purpose rooms.

Understanding the dimensions of a Murphy bed is crucial because it affects not only the comfort and convenience of its use but also the installation process and overall aesthetic of the room.

A Murphy bed that is too large for a room can make the space feel cramped and uncomfortable, while one that is too small may not provide enough sleeping space.

Additionally, the dimensions of the bed will determine if there is enough wall space for installation and if the bed will fit well with other furniture in the room.

In the following sections, we will delve deeper into the standard dimensions of Murphy beds, factors to consider when choosing the right size for your needs, and tips for measuring your space accurately.

Standard Murphy Bed Dimensions

The dimensions of a Murphy bed will depend on the size of the mattress it’s designed to accommodate. Here are the standard dimensions for the most common sizes:

Single Size Murphy Bed Dimensions

Also known as a twin size, a single Murphy bed typically measures approximately 80 inches in height, 45 inches in width, and 15 inches in depth when closed. When opened, the projection is usually around 85 inches.

Double Size Murphy Bed Dimensions

A double size, or full size, Murphy bed typically measures around 80 inches in height, 60 inches in width, and 15 inches in depth when closed. When opened, the bed usually projects about 85 inches from the wall.

Queen Size Murphy Bed Dimensions

A queen size Murphy bed generally measures about 86 inches in height, 66 inches in width, and 16 inches in depth when closed. When opened, the bed usually projects approximately 90 inches from the wall.

King Size Murphy Bed Dimensions

A king size Murphy bed typically measures around 86 inches in height, 82 inches in width, and 16 inches in depth when closed. When opened, the bed usually projects about 90 inches from the wall.

Factors to Consider When Choosing Murphy Bed Dimensions

Choosing the right dimensions for your Murphy bed involves more than just measuring your space. Here are some additional factors to consider:

Room Size and Layout

The size and layout of your room will greatly influence the size of the Murphy bed you can accommodate. Ensure you have enough wall space for the bed when it’s folded up and enough floor space for when it’s pulled down. Also, remember to factor in other furniture and walking paths.

Number of Users

Consider who will be using the bed. A single or double size might be sufficient for one person, but if the bed is meant for two people, a queen or king size would be more appropriate. If the bed is for children, smaller sizes could also work.

Purpose of the Bed

If the Murphy bed is intended for daily use, you might want to invest in a larger and more comfortable size. However, if it’s for occasional guests or as a temporary solution, a smaller size could suffice.

Storage Needs

Many Murphy beds come with built-in storage options like shelves, drawers, or cabinets. If you need extra storage space, you might want to consider a larger unit. However, keep in mind that additional storage will add to the overall dimensions of the bed when it’s closed.

Measuring for a Murphy Bed

Proper measurement is crucial to ensure your new Murphy bed fits perfectly in your space. Here’s how to do it:

How to Measure Your Space

Start by measuring the width, height, and depth of the area where you plan to install the bed. Use a tape measure for accuracy.

Remember that the width should accommodate the bed itself plus any built-in storage or shelving, the height should allow the bed to fold out completely, and the depth should allow the bed to fold up neatly.

Considering Wall Height and Floor Space

The wall height needs to be taller than the height of the Murphy bed when it’s closed. For floor space, measure the distance from the wall out into the room to ensure there’s enough space for the bed to fold down completely. This is typically equal to the length of the mattress plus a few extra inches for bedding.

Accounting for Additional Furniture and Walking Space

Consider other furniture in the room. There should be enough space to move around comfortably with the bed open or closed. Also, ensure that no furniture obstructs the path of the bed as it folds down or up.

Tips for Accurate Measurement

  1. Always use a reliable measuring tool like a tape measure or laser measure.
  2. Measure more than once to verify your numbers.
  3. Note down all measurements as you go along.
  4. Consider the size of the mattress as well as the bed frame.
  5. Don’t forget to account for any additional features like shelves or cabinets.

Custom Murphy Beds

Custom Murphy beds allow you to tailor the bed to your specific needs and preferences. They can be an excellent solution for those with unique space constraints or design requirements.

When to Consider a Custom Size

You might want to consider a custom size Murphy bed if:

  1. Standard Sizes Don’t Fit: If your room is an irregular shape or size, a standard Murphy bed might not fit properly. A custom bed can be designed to fit perfectly in your space.
  2. Unique Design Needs: If you have specific design elements in mind that aren’t typically included in standard Murphy beds, a custom option might be better. For example, you might want built-in shelves, cabinets, or a specific material or color.
  3. Specific Usage Requirements: If the bed will be used frequently or by people with specific needs (such as elderly individuals or children), a custom bed can be designed for comfort, ease of use, and safety.

Pros and Cons of Custom Murphy Beds


  • Tailored to Your Needs: A custom Murphy bed can be made to suit your exact specifications, ensuring it fits perfectly in your space and meets your needs.
  • Unique Designs: You have the freedom to choose unique designs, materials, and features that reflect your personal style.
  • Increased Home Value: A well-designed custom Murphy bed can add value to your home, especially if it enhances the functionality and aesthetics of a room.


  • Cost: Custom Murphy beds are generally more expensive than standard sizes due to the additional labor and materials required.
  • Time: It can take longer to design and build a custom Murphy bed compared to purchasing a pre-made one.

Potential Dimensions for Custom Beds

The dimensions of a custom Murphy bed will depend entirely on your specific needs and the size of your room. However, they should still roughly align with standard mattress sizes (single, double, queen, and king) for ease of bedding fit. The depth when closed and projection when open can be adjusted based on your space and design preferences.

Installation Considerations for Murphy Beds

While purchasing a Murphy bed is the first step, proper installation is essential to ensure it’s safe and functional. Here are some key considerations:

The Importance of Professional Installation

Professional installation offers several benefits:

  1. Expertise: Professionals have extensive experience and know-how to install Murphy beds correctly, ensuring they function smoothly and safely.
  2. Time-Saving: Professionals can complete the installation faster than an inexperienced individual, freeing up your time.
  3. Customization: A professional can adapt the installation process to accommodate unique room dimensions or design features.
  4. Safety: Professionals are aware of all safety protocols and ensure the bed is securely installed to prevent accidents.

How Dimensions Can Affect Installation Process

The dimensions of your Murphy bed can significantly affect the installation process. Larger beds may require more complex assembly and installation processes. If your room has unique dimensions or features (like sloped ceilings or narrow walls), it might necessitate custom adjustments during installation.

Safety Precautions During Installation

Safety should always be a priority during installation. Here are some precautions to consider:

  1. Secure Mounting: Ensure the bed is securely mounted to the wall to prevent it from tipping over.
  2. Proper Use of Tools: Make sure tools are used correctly to avoid injury.
  3. Follow Instructions: Always follow the manufacturer’s instructions closely when installing the bed.
  4. Check Mechanisms: After installation, double-check all mechanisms (like locks and hinges) to ensure they’re functioning correctly.


Understanding the dimensions of a Murphy bed is crucial for anyone considering this space-saving furniture piece. Accurate measurements not only ensure that the bed fits perfectly in your space, but also that it functions optimally and safely.

Custom Murphy beds offer a tailored solution for those with unique space constraints or design requirements. However, they do come with increased cost and time considerations. It’s essential to weigh these factors against the benefits of a bed that’s custom-made for your needs.

Professional installation is highly recommended for Murphy beds. This ensures the bed is securely mounted and all mechanisms are functioning correctly, providing peace of mind and optimizing the bed’s longevity.

Overall, a Murphy bed can be a fantastic addition to your home, offering both functionality and style. But like any significant purchase, it requires careful consideration and planning. Always remember to measure twice, consider professional installation, and factor in your unique needs and preferences when choosing your Murphy bed. With careful planning, your Murphy bed can provide comfort, save space, and enhance the aesthetics of your room for years to come.
