In this in-depth guide, we’ll cover everything you need to know about average bedroom sizes in the UK. We’ll go over the minimum size requirements for bedrooms, and typical sizes for both single and double bedrooms.

So let’s dive right in and explore the world of UK bedroom sizes!


Legal Requirements for Bedroom Sizes in the UK

One of the first things people often wonder is: “Is there a legal minimum size for bedrooms in the UK?”

Well, the answer is a bit tricky. Technically, there isn’t a specific law that dictates exactly how big bedrooms (or other rooms) must be in residential properties.

The main rules that need to be followed when building or renovating homes are:

  • Planning permission
  • Building regulations

In most cases, you’ll need to comply with building regulations. And for certain projects, you may need planning permission as well. But these don’t usually set strict minimum sizes for rooms like bedrooms.


However, in 2015, the government introduced something called the “National Space Standard.” The goal was to provide a guideline for the minimum sizes of rooms in new homes.

It’s not a hard-and-fast law, and it’s up to local authorities to decide whether to enforce it.

Then in 2021, things changed a bit. Now, the space standard applies to new homes built under “permitted development” (a type of pre-approved development that doesn’t need planning permission).

So what does the national space standard say about bedroom sizes?


Let’s take a look.

Single Bedroom Sizes

Single bedrooms are meant to fit one person comfortably. The space standard assumes that a typical single bedroom will contain:

  • A bed
  • Storage (like a wardrobe)
  • Other essential furniture

There should also be enough space to easily move around and access everything in the room.

Single bedrooms are often used for:

  • Children
  • Guests
  • Additional bedrooms in a home

These types of bedrooms usually have smaller beds and may not need as much storage or furniture as the main bedroom. For kids’ rooms, you might include a small wardrobe, dresser, or toy box to help keep things tidy.

Minimum Size for Single Bedrooms

According to the national space standard, the minimum size for a single bedroom should be:

Dimension Minimum
Floor Area 7.5 sq m (80.7 sq ft)
Width 2.15 m (7 ft)

However, there are different rules for bedrooms in Houses of Multiple Occupation (HMOs). Since 2018, HMO bedrooms for a person over 10 years old must have a floor area of at least 6.5 sq m (70 sq ft).

Average Single Bedroom Size

In practice, a single bedroom that’s around 3.4 m x 3 m (11.2 x 9.8 ft) is generally considered spacious enough. That works out to a floor area of about 10.2 sq m (110 sq ft).


For young kids, you may not need a full-size single bed.

Smaller options can work well in tighter spaces:

  • Small single bed: 0.9 m x 1.9 m (3 x 6.2 ft)
  • Double bed for kids: 1.2 m x 1.9 m (4 x 6.2 ft)

Double Bedroom Sizes

Now let’s look at the common sizes for double bedrooms (also called master bedrooms). These are typically used by:

  • Couples
  • Siblings sharing a room
  • An individual who wants a larger bed

Double bedrooms generally need to be more spacious than single rooms, as they need to comfortably fit two people along with larger furniture, more storage, and extra items like seating.


Minimum Size for Double Bedrooms

The national space standard recommends that double bedrooms have a minimum size of:

Dimension Minimum
Floor Area 11.5 sq m (123.8 sq ft)
Width 2.55 m (8.4 ft)

Again, the rules are a bit different for HMOs. Double bedrooms in an HMO must be at least 10.2 sq m (110 sq ft) in size.

Average Double Bedroom Size

In an average home, a “typical” size master or double bedroom is around 4.5 m x 4.5 m (14.8 x 14.8 ft). This gives a floor area of about 20.25 sq m (218 sq ft).

The main factor that determines how big the bedroom should be is usually the bed size.


Common bed dimensions are:

  • Double bed: 1.3 m x 1.9 m (4.3 x 6.2 ft)
  • King bed: 1.5 m x 2 m (5 x 6.6 ft)
  • Super king bed: 1.8 m x 2 m (6 x 6.6 ft)

In addition to the bed, double bedrooms usually include:

  • Nightstands
  • Dressers
  • Wardrobes or closets
  • Extra seating or furniture

So the average size double bedroom gives you enough space to fit all these comfortably, with room to move around the bed and not feel cramped.

Other Things to Consider for Bedroom Sizes

While the size of the bedroom in square meters or feet is important, there are some other key factors to think about too:


1. Natural Light and Ventilation

It’s not just about the size – bedrooms should also have enough natural light and fresh air. This helps create a comfortable, healthy environment.

When buying or renting, look for bedrooms with windows that let in plenty of sunlight and allow for good airflow. This is important for:

  • Maintaining a good mood
  • Promoting overall wellbeing
  • Keeping the air fresh

2. Storage Space

Another vital consideration is whether the bedroom has adequate storage. While there aren’t regulations about exactly how much is required, it’s an important practical factor.

Ideally, a bedroom should have enough built-in storage for the occupant’s belongings. This could include:

  • Closets
  • Wardrobes
  • Shelving
  • Cabinets

Having designated storage helps keep the room clutter-free and everything neatly organized. It’s a key part of making the bedroom a functional and relaxing space.

3. Ceiling Height

While there aren’t rules about exact ceiling heights for bedrooms, it’s useful to know what’s typical. In the UK, the standard ceiling height is around 2.4 m (7.9 ft).

This can vary somewhat based on the age and style of the property:

  • Older buildings may have lower ceilings.
  • Newer homes often have higher ceilings for a more spacious, modern feel.
  • Converted loft bedrooms may have lower ceilings around 2.1 m (6.9 ft).

Interestingly, ceiling height is only regulated for certain areas like staircases and landings. Building rules state that there must be at least 2 m (6.6 ft) of headroom in these spaces to avoid banged heads!


Frequently Asked Questions About UK Bedroom Sizes:

Let’s go over a few common questions people have about bedroom sizes in the United Kingdom.

  • 1. What is the average master bedroom size in the UK?

The average master bedroom in a UK home is approximately 4.5 m x 4.5 m (14.8 x 14.8 ft). This works out to a floor area of around 20.25 sq m (218 sq ft).

However, actual sizes can vary quite a bit depending on the specific property. Newer homes tend to have more generously sized master bedrooms compared to older properties.

  • 2. How big is a small double bedroom?

A small double bedroom is typically around 3.5 m x 3.5 m (11.5 x 11.5 ft), giving a floor area of about 12.25 sq m (132 sq ft). This is a bit more compact than the average double bedroom size but is still functional for two people.


In a small double bedroom, you’ll likely have:

  • A double bed (1.3 m x 1.9 m)
  • One or two nightstands
  • A wardrobe or closet
  • A dresser

You may need to opt for more space-saving furniture or arrange things efficiently to make the most of the available space in a smaller double bedroom.

  • 3. What is the minimum size for a single bedroom in the UK?

According to the national space standard, the minimum size for a single bedroom is 7.5 sq m (80.7 sq ft). It should also have a minimum width of 2.15 m (7 ft).

However, it’s important to note that these are guidelines rather than strict legal requirements. Some properties may have single bedrooms that are smaller than this, particularly in older buildings or converted spaces.


For HMOs, a single bedroom must be at least 6.5 sq m (70 sq ft) for a person over 10 years old.

  • 4. Are there different bedroom size regulations for HMOs?

Yes, there are specific minimum bedroom size requirements for Houses in Multiple Occupation (HMOs):

  • Single bedroom for a person over 10: at least 6.5 sq m (70 sq ft)
  • Double bedroom: at least 10.2 sq m (110 sq ft)

These regulations have been in place since 2018 and apply to HMOs in England. They help ensure that tenants have a sufficient amount of personal space and a safe, healthy living environment.

  • 5. How can I make a small bedroom feel more spacious?

If you have a bedroom on the smaller side, there are several ways you can make it feel bigger and more comfortable:

  • Use light colors: Lighter shades on the walls, floor, and furniture create a feeling of openness. Avoid dark, heavy colors that absorb light.
  • Maximize natural light: Keep windows unblocked to let in as much sunlight as possible. Use sheer or light-colored curtains.
  • Declutter and organize: Get rid of any unnecessary items and keep surfaces clear. Use efficient storage solutions to avoid a cramped feel.
  • Opt for multi-functional furniture: Choose pieces like storage beds or ottoman benches that serve multiple purposes to save floor space.
  • Hang mirrors: Well-placed mirrors can make a small bedroom feel more expansive by reflecting light and creating the illusion of depth.
  • Keep scale in mind: Select furniture that fits the proportions of the room. Avoid oversized pieces that dominate the space.

With some smart design choices, you can make even a compact bedroom feel open, airy, and inviting.


Bedroom size is an important consideration when buying, renting, or renovating a home in the UK. While there aren’t strict legal minimums in all cases, the national space standard provides useful guidelines:

  • Single bedroom minimum size: 7.5 sq m with a minimum width of 2.15 m
  • Double bedroom minimum size: 11.5 sq m with a minimum width of 2.55 m

In practice, the average double bedroom is around 4.5 m x 4.5 m (20.25 sq m), while a typical single is about 3.4 m x 3 m (10.2 sq m).


Bedroom size requirements differ slightly for HMOs, with a minimum of 6.5 sq m for a single and 10.2 sq m for a double.

Beyond the floor area, it’s also important to consider factors like natural light, ventilation, storage space, and ceiling height when assessing a bedroom’s size and functionality.

With this complete guide, you’re now equipped with all the key information about average bedroom sizes in the UK!

Whether you’re property hunting, planning a renovation, or simply curious, you can use these insights to make informed decisions and create comfortable, inviting bedroom spaces.
