Mattress Sizes and Bed Dimensions Guide 2023

The bedroom is where we spend a third of our lives sleeping, so it makes sense that we should invest in making the space as calm and restful as possible - but with the array of different bedding options, it can be difficult to know which size is right for you and your needs.

Most couples in the UK sleep in a double bed, which is often uncomfortable and doesn’t offer a premium sleeping experience. At Rowen Homes we offer a range of bed and mattress sizes if you’re looking to upgrade your master suite.

With all of this in mind, we’ve put together a comprehensive guide on how you can maximise cosiness and comfort without sacrificing sleep quality or style.

Let’s dive in.

UK bed sizes

The UK offers a range of different standard bed sizes to suit different needs. Whether you’re looking for a smaller bed or wanting to max out, we’ve laid out the different options available to you.


Dimensions: 90cm x 190cm

Single beds are great for small spaces where floor space is at a premium. This bed size is also ideal for children and teenagers; the 90cm width means there is plenty of room for a single person to be comfortable.

Taller teens might want to opt for a bed extender or upgrade to a bigger size bed.

Small double

Dimensions: 120cm x 190cm

A small double is a relatively new bed size in the UK market. Sitting right between a single and a double, a small double is good for the growing child wanting some more space.

While the small double can work as a space-saving option for a couple, we wouldn’t recommend this as a long-term solution unless you’re comfortable with snuggling up to your partner at night.


Dimensions: 135cm x 190cm

Similar to the small double, the regular double bed size is a popular choice for two adults in a smaller bedroom, but also works well for a teenager or single adult looking for some extra space to snooze.

We’d recommend sizing up for taller adults or those who struggle to sleep through the night uninterrupted, as sharing a double with your partner can mean you’re woken up more from movement.


Dimensions: 150cm x 200cm

A king-size bed is a great option for couples looking to get a good night’s sleep. The king size is roomier and longer, giving taller people more space to stretch out and be comfortable.

However, not every bedroom size can accommodate a king-size bed - make sure to check the dimensions of your master bedroom so you can fully enjoy the benefits of a king-size bed.


Dimensions: 180cm x 200cm

A definite step up from the king size, the superking bed offers a premium sleeping experience for couples. With an extra 30cm of width compared to a king size bed, the superking is great for couples needing some extra space and with the bedroom size to accommodate it.

The superking is also a good option for families that enjoy snuggling up at the weekends with plenty of room to spare.


Dimensions: 215cm x 215cm

This is the ultimate bed size for those couples that value their space or who want to bring the upscale hotel vibes to their bedroom. The emperor bed offers additional width and length to the superking, making it ideal for taller people or those who simply want the most luxurious option available on the market.

Not every retailer sells emperor mattresses and bedding as standard, but Rowen Homes has a selection of frames in this size to elevate your bedroom to the next level of comfort and style.

Accessories for your bed

Whatever size you go for, accessorising your bed will make your bedroom feel like the cosy, luxurious haven you could only dream of.


Your choice of headboard is not only important to support your back while sitting in bed, but to make a statement in your bedroom. A luxury headboard complete with premium fabrics like leather or suede could be the dramatic finish to your master suite you’ve been looking for.

Headboards can be attached to the wall or bed, depending on the style. To get a boutique hotel vibe in your bedroom, opt for a floor-to-ceiling headboard that maximises glamour.

Pillows and cushions

Choosing a high-quality pillow will not only enhance your sleep, but fit in with the look of your premium new bed. A standard pillow is 48cm x 74cm, but you can buy king, superking and emperor-size pillows to suit your newly upgraded sleeping situation.

For pillow covers, opt for plush fabrics like Egyptian cotton or percale with a high cotton thread count for extra softness and to add a little touch of opulence.

With decorative cushions, plump for a few key statement cushions in luxurious fabrics like faux fur and suede to elevate your boudoir to new heights. Add in a bolster pillow to add texture and variety to your bedscape.


The right lighting can completely elevate your bedroom. A pair of matching table lamps that flank your new bed will create a cohesive look in the bedroom, which promotes a restful night’s sleep, while a modern chandelier will complete the makeover and make a statement.

Choosing dimmable LEDs that create a cosy, warm glow will make you never want to leave your bed and give you enough time to wind down for sleep. If you’re feeling bold then opt for colour-changing bulbs where you can create different scenes to match your mood.

Choosing the right bed size and mattress for your needs might not always be easy, but it’s worth every penny investing in a good-quality bed that you’ll be happy with for years to come.
