Biggest Bed Size UK

Last Updated: June 22, 2021

We all want to be able to stretch out and enjoy as big a bed as possible. Many of us grew up sleeping in cramped singles, so getting the biggest bed size we can afford, and fit in our bedroom, can feel like a real mark of adulthood. What could this bed be, and how common are they?

Studies✓ show that some couples that sleep in the same bed may have relationship issues related to poor sleep quality. In some cases, this can be fixed by something as simple as getting a larger bed and a better mattress. If you're wondering what's the biggest bed size, then we can help. Let’s take a closer look at some of the biggest bed sizes the UK has to offer.

What Bed Sizes Can I Choose?

Luckily, there are six standard bed sizes that you can choose from in the UK. These should be the same regardless of the brand that you are shopping with, and they are:

• Small single – 75 x 190 cm

• Single – 90 x 190 cm

• Small double – 120 x 190 cm

• Double – 135 x 190 cm

• king – 150 x 200 cm

• Super king – 180 x 200 cm

While many of us think that a king-sized bed is the largest that we can get our hands on in the UK, it is in fact the super king. This is one of the largest types of bed out there, and great for those who want a little bit more space.

The standard sizings are also great for helping to find the perfect bed for your needs. Some people might prefer to buy their mattress from one manufacturer and then look elsewhere for their bedframe. Having the standard sizes in place makes it much easier for you to do so.

What Are The Euro Sizes?

Some manufacturers also offer an additional three sizes of bed that might work for you. Not every brand does have the Euro sizes, but if you find one that does carry them, you will usually find that they measure as follows:

• Euro single – 90 x 200 cm

• Euro Double – 140 x 200 cm

• Euro king – 160 x 200 cm

As can be seen, these are slightly different from the UK standards. A Euro single and double are slightly roomier than their UK counterparts. However, the Euro king is slightly wider than the UK super king. So if you have space and the budget then you might want to consider splurging for the super king.

Make sure to pay close attention to whether or not you are purchasing a Euro or UK sized bed base. This will dictate the mattress that you put on top. Accidentally purchasing a Euro double bed base when you meant to buy the UK double means that you'll need to find a mattress that fits this so you do not have gaps or overhang.

Are These The Biggest Beds I Can Find In The UK?

Technically, no. The beds listed above are the biggest standard bed sizes that you find. Walk into any store with beds, from big department stores to independent stores, and you'll normally find all the standard sizes. Some stores even offer extra-large bed- and mattress sizes such as Emperor (200 cm x 200 cm) and Caesar (245 cm x 220 cm).

That being said, you might also be able to find companies who are able to custom-make you a larger bed. If you would like even more space, there are companies that can make you a customised bed that measures pretty much any width or length you'd like if you truly want to get your hands on the largest bed size that UK manufacturers can offer.

What Is The Right Bed Size For Me?

If you are thinking about investing in a new bed and want to go a little bigger than a standard double, there are a few considerations you should make. Many of us start out with just a standard double, either as a teenager or as an adult, but we can soon find ourselves wanting more space.

The first consideration that should always be made is if you're sleeping alone or together with a partner. If you need a specific couples mattress, such as one that reduces movement from side to side, make sure the size of the mattress matches the bed size. Secondly, the height of either you or your partner. 190 cm is equal to 6’3”, so if you or your partner is taller than this then you should probably think about getting a bed that is larger than a double to accommodate this. Nobody likes to feel like they are squashed in bed, or that they have to sleep across the diagonal to be able to stretch out comfortably.

The other major consideration that has to be made is in regards to the size of your room. If you have a massive bedroom then you'll be able to just go ahead and order whatever size you want. However, if you have limited space, you need to think carefully about the size that you order.

You don't want the bed to overpower the room, and you also want to make sure that there is plenty of space around it so you can walk around freely. Even if the bed goes against one wall, you still want there to be enough space on the other side.

Make sure that you take the route to the bedroom into consideration too. Though most bed frames can be disassembled and many mattresses can be rolled up, there might be some tight corners and staircases for you to squeeze your bed up.

Getting a bigger, high-quality bed can be the first step in helping you acquire your perfect night’s rest. If you were wondering what is the biggest bed size, then we hope this article has helped.
