So, you have decided to dedicate enough space to your bedroom to make it a true master suite. If a typical bedroom size isn’t enough for you, designing a master bedroom is indeed a great decision.

However, its comfort, convenience, beauty, and functionality are also accompanied by specific considerations.

As a result, identifying the average master bedroom size isn’t enough — you also need to know specific nuances, such as how to optimally use the space and which types of furniture can complement your room layout.

Having your needs in mind, we decided to create a simple and detailed guide for master bedroom dimensions. Let’s understand how big is a master bedroom and take a look at some inspiring large master bedroom ideas.

What is a Master Bedroom?

The master bedroom serves the same function as your primary bedroom. In fact, this is the largest bedroom in the house that features an in-suite bath and can have diverse functionality.

In families, master bedrooms are usually dedicated to parents and sometimes, they even share them with small children. Often, master bedrooms also feature massive closets, not to mention master bathrooms.

All master bedrooms have one key thing in common: it is a private space for you, where you need to rest and take care of yourself. This is why planning the master bedroom size correctly has huge meaning when building or planning your house.

What’s the Typical Size for a Master Bedroom?

The one specific formula that would apply to all types of bedrooms doesn’t exist, as each house has its own design and requirements. Therefore, before you decide to choose your bedroom size, it’s important to identify standard dimensions for a master bedroom.

Of course, more space means more opportunities to design but it’s perfectly possible to get creative even with a small or average size bedroom.

  • Small Master Bedroom Size

    According to standard measurements, if your master bedroom is between 12 and 18 feet, then it is considered small. For that kind of room, the average height would be 8 feet. If you have a similar space for your master bedroom, then it is best to use some space tricks to avoid over-furniture.

  • Medium Master Bedroom Size

    A master bedroom is considered a medium one if it is up to 15-20 feet. Such sizes of bedrooms are normal for 2,000-2,500 square feet of houses. For an average size master bedroom, the normal height is also 8 feet.

  • Large Master Bedroom Size

    Master bedrooms, ranging from 16 to 22 feet square, are large bedrooms. If you have around 2 ‘999 square feet of house, then this size of the master bedroom is the best to have. Compared to smaller sizes, in large bedrooms, an 8-10 feet height ceiling can be used.

  • Extra Large Master Bedroom Size

    There also exists a definition for the extra large master bedroom, which is ideal for houses ranging from 3,000 square feet. The size of extra-large bedrooms starts at 20-22 feet and for the ceiling height, it sometimes goes up to 13 feet.

5 Things to Consider Before Choosing Your Master Bedroom Size

Now you already know that it’s a complex task to determine the ideal size for your master bedroom. There are a lot of details to consider when designing a space that would allow you to rest and take care of yourself in a luxurious way.

Let’s clarify some key aspects regarding master bedroom dimensions to help you find the best size for your master bedroom:

1) Room Layout

Room layout completely depends on the size of the master bedroom. The main task here to handle it is avoiding over-furniture and maintaining space between pieces of furniture. After all, you will be spending a decent amount of time in your master bedroom.

Ideally, the layout of your room should provide enough space for sleeping, clothing, and resting. The layout also depends on where doors and windows are placed. So, consider how much light you require to make your master bathroom as cozy a place for rest as possible.

2) The Size of Your Furniture

Another thing that significantly affects the functionality of your bedroom is the size of the furniture. The rule of thumb here is that the furniture should be suitable for the average square footage of bedroom. Master bedroom furniture usually comes in massive sizes, such as a double bed, a closet enough for two people, and side bed tables. But again, we recommend avoiding buying furniture until the layout of your master bedroom is already determined.

3) Your Budget and Home Value

Of course, budget is the basic concern before making any decision about renovating a house. The thing is that designing a quality bedroom, regardless of its size, requires a decent budget. Therefore, you should also keep your budget in mind before determining the average size of a master bedroom.

If your budget is tight, then you should be more balanced with your wishes, tastes, and opportunities. Never forget that large bedrooms and luxurious features in your master bedroom always cost a lot. But on a positive note, increasing your budget directly means making a wise investment in your Las Vegas house. Usually, the more square feet of average bedroom you dedicate, the higher your property value.

4) Cleaning and Maintenance

The master bedroom is a private space in your house used for day and night routines, resting, and sleeping. Therefore, it’s natural that people spend significant amounts of time in their master bedrooms. And this, in turn, means that when you have a master bedroom, you’ll need to be more concerned about its maintenance than with a standard bedroom size.

The rule here is simple: smaller bedrooms require less time to clean, while larger ones demand more effort. On the other hand, deep cleaning is harder in small master bedrooms, whereas, in large master bedrooms, it is easy to move a vacuum cleaner. So, if you know that maintenance will be a problem, then maybe you should go with a smaller size.

5) Heating and Cooling

The larger the space, the greater the demand for heating and cooling resources. This is especially true if you are moving into a newly built home where you will be responsible for installing heating in a way to provides comfort in every room. In this case, professional consultation regarding heating requirements is a must.

On the other hand, if your house has a pre-existing system, then all you have to do is align your master bedroom’s design with the capacity of these systems. Again, keep in mind that higher heating and cooling demands can significantly impact your budget.

Functional Design Tips for Your Master Bedroom

Although a lot depends on average bedroom dimensions, the size isn’t everything. Even if you have already designed the ideal layout of your room, that doesn’t mean that the typical master bedroom size guarantees comfort. That’s why we recommend taking a look at these big bedroom ideas to enhance the functionality of your master bedroom:

  • Consider larger windows or a skylight

    Perhaps, not surprisingly, the comfort and functionality of your master bedroom greatly depend on the lighting. The thing is that dark bedrooms never feel cozy and comfortable enough. Including larger windows or even a skylight can help you increase the natural light in the room and make it appear more spacious. And this, in turn, is extremely helpful when space is limited in your master bedroom.

  • Add a seating area

    Having an additional seating area is a great way to make the space even more luxurious. It’s especially helpful if you need an extra spot for reading, relaxing, or engaging in hobbies. This addition will add comfort and coziness to the room.

  • Include built-in closets

    Built-in storage, in general, comes with a lot of benefits, as it can effectively maximize your space. First of all, it gives you the chance to maximally use the space, which is extremely important when you have a small master bedroom. Besides, it can prevent the room from feeling over-furnished, as well as, keep your space neat and personal.

  • Divide large rooms in two

    Creating different zones in large bedrooms is very helpful. One zone should be sleeping, whereas another is based on individual needs and choices.

  • Personalize with art

    Decorations play an essential role in creating a good aesthetic and vibe in the master bedroom. You can use different decorations, such as plants and art accessories, to make the space cozy. This will make the space more beautiful, no matter whether it’s a typical master bedroom size or a bigger one.

Master Bedroom Size vs. Standard Bedroom Size

As we already mentioned, while planning home design, choosing the right bedroom sizes is a significant aspect. But paradoxically, sometimes you can achieve more by working with less. This means that even if space is limited, clever design and thoughtful arrangement can turn a smaller master bedroom into a cozy, functional area.

For example, let’s compare standard bedroom size in feet with master bedroom sizes. A standard bedroom in a typical US home is about 11′ x 12′, which is 132 square feet. This size is adequate for fitting a queen-sized bed and basic furniture if you want to still allow movement in the room.

On the other hand, master bedrooms are generally larger. The minimum size for the master bedroom is from 12’ to 16’, without closets. This is about 240 square feet and sometimes, it can even go up to 18′ x 20′ or 360 square feet.

Thanks to these average bedroom dimensions, your master bedroom can offer more flexibility when it comes to layout and furniture sizes.

6 Essentials for Your Luxurious Master Bedroom

Now, after providing tips for choosing adequate average bedroom square footage, it’s time to consider the other remaining aspects that you need to create a luxury bedroom. Some of the aspects that differentiate standard bedrooms from luxurious master bedrooms include quality mattresses, a well-aligned color palette with the overall design, and some smart features.

  • Choose high-quality mattresses

    For the custom-size featured bed, choose one that is comfortable according to your preference for sleeping support and comfort. Memory foam, latex, and hybrid types are some of the best-quality mattresses available today.

  • Layered lighting

    Having different types of lighting enhances the ability of a user to change the ambiance to fit their needs. As for your main sources of lighting, go for overhead lamps for general purposes, task lights for activities like reading, and ambient light to create a cozy atmosphere. That is especially important for big bedroom areas.

  • Smart home features

    Make your bedroom a smart one by integrating advanced technologies for heightened comfort and convenience. For example, smart thermostats can cool down or warm up the room, depending on the conditions for quality sleep. Another option is getting smart speakers that can transmit voice-controlled sounds of music or white noise, which is essential for relaxation.


  • Declutter and organize

    If you overload your room with plenty of objects and furniture, chances are that you won’t be able to relax. That’s why it’s important to declutter and organize. Just try to make the most of your storage and include features, such as bed drawers, wardrobe organizers, a mayhem of stretchable sections, and bedside tables that come with in-built compartments.

  • Choose calming colors and textures

    People who have hues that favor muted, soft tones usually find it easier to rest and relax. These colors are often identified as nostalgic colors, such as pastels or neutrals. Pair natural textures like wood, cotton, and linen to establish a strong tactile that brings warmth to the space.

Pros & Cons of Different Master Bedroom Locations
