How Wide is a Double Bed: Measurements and Sizes

The first documented double bed used was by King Louis XIII of France in the 16th century. He made his court agree to sleep every night with each other on two beds prepared at opposite sides of the room.

The popularity of double beds increased during the 19th century when people looked for ways to accommodate more people in their homes. Due to high infant mortality rates, they had smaller families, and many children died before or after reaching maturity.

During this time, it became more common for couples to produce fewer children. It is important to note that four out of five bedrooms were used as living rooms, dining rooms, and family spaces until Victorian times.

Bed sizes: What’s the difference?

I. Double Size Bed

a) In the UK, a standard double bed and mattress size will measure 4’6″ wide x 6’3″ long (137cm x 190.5 cm) with a depth of 5′ (152cm). This is an industry-standard size that can be found in almost all retail stores offering beds for sale.

b) The width of the mattress should always be stated on the label attached to it. If this tag has been removed or cannot be found, you can assume it’s roughly feet wide.

c) It is important to note that the standard UK double bed size does not meet the minimum recommendations of 6′ long by 2.4m wide that adults advise to prevent health problems such as neck and back pain.

II. Queen Size Bed

a) Queen size beds are available in the UK. However, these tend to measure 4ft 6″ x 6′ 3″.

b) This means a queen bed may provide you with extra room at the expense of having a slightly narrower length which isn’t an issue if both people enjoy sleeping close together.

III. King Size Bed

a) If you’re looking for more space, then a standard king-size bed should be your choice!

b) The length of a king-size mattress is around 1 foot wider than a super king at 6’3″ long, and you’ll get over 1 foot more width from it being around 4’3″ wide.

c) The downside to this extra space is that king-sized mattresses tend to be much harder to find.

How much does a double bed cost?

The average price of a standard double bedroom set(bed and mattress) will be between £250-£500.

In America, prices for a queen-size bed will range from $299 to $1,699 depending on the model and materials used.

The most expensive purchase you’ll make is your king-sized mattress, as these can cost upwards of £1,000.

Is it possible to fit 2 standard double UK beds side by side in a small room?

The short answer: Yes, you’ll have very little walking space around the edges! It might not always work if your decorating tastes include large ornaments and paintings on the walls.

If the combined widths of two beds exceed 4’6, they will not get into most rooms no matter how hard you try!

If you plan on getting a super king-size bed, then there should be plenty of free space for two even if the room isn’t huge – providing each bed is 4’6″ wide.

There are different ways to make your room appear larger:

  • the easiest is to remove any excess clutter, especially items that seem to take up extra space on the floor.
  • Mirrored wardrobes, bay window seats, or even furniture that appears to ‘float’ in the air giving an illusion of more open space nearby.

Double-size beds are usually smaller than king-size mattresses in the UK. There are, however, other differences between a double and king-size bed and mattress sizes.

Are single beds wider than double?

As far as measurements g, a standard single bed is 2ft 6 “x 3ft 3,” making it only slightly wider than a single mattress at just under 3ft.

The main difference between a standard double and single bed is in the number of people sleeping on them: A standard double bed will hold two people, while a single can only sleep one person at a time. This means that there is much less space for each person than when they’re sharing a larger mattress.

If you’re looking for extra-wide, you should consider super king/Cal king-size beds around 1 foot wider than an average UK double mattress.

These may be suitable if both people in the relationship cant sleep without touching or if one partner sleeps particularly spread out!

What’s the difference between a small double and a twin?

A small double bed measures 4ft 6″ x6ft 3″, so it’s slightly wider than a standard double mattress but around 12 inches shorter, making them suitable for smaller rooms or if you’re short on space.

The main difference between small doubles and singles is that the width is usually similar; however, small double mattresses are often deeper (taller) than twin-size ones.

This means that there’s more space to move about on the bed for each person and more room at the headboard too!

How much floor space does a standard double bed take up?

A standard double mattress is considered to have 4ft 6″ length x 6ft 3 width, which typically measures 5’6″ across at its widest point.

If you use a tape measure or some string to mark out these edges on the ground, you’ll see that a 4ft 6″ wide double bed takes up around 36 square feet of floor space. However, a standard king-size mattress is usually measured as 5′ long by 6’3,” so it takes up around 61 square feet of space.

What’s the difference between an American and British double bed?

The obvious differences are mainly down to measurements, with American doubles being much wider than UK ones.

  1. The width of a US standard double measures 30 inches more than a 4ft 6″ wide UK double, which makes it nearly 2ft 7″ or 78cm wide at 5’7″. This means that two US standard double beds placed side-by-side will take up nearly 3ft more space than a 5ft 7″ wide UK double bed!
  2. You may also come across extra-long beds, which are slightly narrower at 3’3″ than the usual 4ft 6″ of a standard double in the UK. This size is often favored by younger people who aren’t very tall or couples who are significantly shorter than the other.
  3. If you’re looking for a wider mattress, check out super king/Cal king size mattresses – these are around 1 foot wider again and nearly 2feett longer than a standard king-size mattress,s making them more suitable if both people can’t sleep without touching.

Do different countries have different sizes of mattresses?

There’s more than one reason why this question has been asked so frequently.

When you try and purchase a new mattress in the UK, you’ll notice that there aren’t as many options or combinations to choose from as in other countries. It’s mainly down to different sizes and comfort levels for each country and differences in design.

For example, Americans prefer softer mattresses compared to those living in the UK, where most people generally prefer firmer types.

This can be traced back to cultural traditions such as bedtime routines and sleeping positions, and overall body weight, so it’s no surprise that styles vary between continents!

Does Material affect the Size of a Double Bed?

The material that the mattress is made from can affect its size due to internal construction. For example, foam mattresses tend to be much smaller because they’re denser pieces of material.

Mattress sizes vary by 1″ and 3″ depending on thickness, but foam ones are often around 10″ deep compared with up to 20″ or more for other types.

If you’re looking for a bed deeper than standard, choose ones made from memory foam as this will compress when you sit/lie on it, so it takes up less space!

Take a look at our memory foam range if this sounds like something you would be interested in.

Do European Queen beds come in single sizes?

As far as measurements go, queen-size mattresses tend to be around 4ft 6″ wide and 6ft 3″ long – this gives them an overall size of 60in x 80in which is slightly larger than the average UK double bed at 5ft wide by 6ft 6″.

This difference in measurements can make a queen-size mattress feel smaller overall because the length often makes up for the width of fitting two people.

It’s also important to consider how much space is between each person on the mattress too!

Olympic Queen Mattress Dimensions

An Olympic queen mattress is 6 inches wider than a standard Queen size mattress.

With dimensions of 66 x 80 inches, it’s designed with two people in mind but can also work for one person who likes to spread out or share the bed with their pet.

What double bed frames to choose from?

The easiest way to make up the difference in size between a single bed and a double is using a divan bed frame/box spring set. These provide all-around support to the mattress while ensuring that it sits at the right height for you to get into or out of bed easily.

If only one person is using the bed, then a slatted base is a good choice as these provide extra spring and ventilation, which you’ll appreciate if you sleep hot!

For additional support, choose an upholstered headboard that will increase the level of comfort for each sleeper while also making it look more stylish at the same time.

Wooden or metal designs are available in different styles, so take a look at the different options in store if you need some inspiration.

What size of mattress fits bunk beds?

This will depend on the type of bed you have and what size you need it to be. For twin beds (for two children), choose a mattress that is no more than 6ft long, while larger bunk beds require longer ones too.

If you’re looking for a double or full-size mattress, bear in mind that these tend to be slightly longer than usual while also being deeper too – often 10″ or more.


Based on the above information, double beds are around 6ft wide,e but this can vary by up to 3″ depending on material type and thickness.

If you’re looking for extra room in the bed, then queen-size beds are best because they’re generally larger than standard UK mattresses with slightly different measurements (they’re wider, not taller).
