Below, we have compiled comprehensive charts to serve as your definitive guide. A useful tip: many people prefer to choose bed linen one size larger than their mattress-for instance, a King size duvet on a Double bed-for a more generous and opulent drape.
UK Standard Bed & Mattress Sizes Chart
As specialists in fine linens for the UK's finest homes and hotels, we use these standard dimensions. This chart details the most common mattress sizes available in the United Kingdom, from compact options for children's rooms to the ultimate indulgence of an Emperor bed.
| UK Size Name | Dimensions (cm) | Dimensions (inches) | Typical Use |
|---|---|---|---|
| Small Single | 75 x 190 cm | 2'6" x 6'3" | Toddler beds, small guest rooms |
| Single | 90 x 190 cm | 3' x 6'3" | Children's rooms, single adults |
| Small Double | 120 x 190 cm | 4' x 6'3" | Teenagers, guest rooms, single adults wanting more space |
| Double | 135 x 190 cm | 4'6" x 6'3" | The most common size for couples |
| King | 150 x 200 cm | 5' x 6'6" | Couples desiring extra room and length |

| Emperor | 200 x 200 cm | 6'6" x 6'6" | The pinnacle of luxury, for very large rooms |
European (EU) Bed & Mattress Sizes Chart
Often found in furniture from brands like IKEA, European sizes differ slightly from their UK counterparts. For example, an EU Single is 10cm longer than a UK Single, which is an important consideration when purchasing a bed frame and mattress from different suppliers.
| EU Size Name | Dimensions (cm) | Dimensions (inches) |
|---|---|---|
| EU Single | 90 x 200 cm | 35.4" x 78.7" |

| EU King | 160 x 200 cm | 63" x 78.7" |
United States (US) Bed & Mattress Sizes Chart
If you are purchasing from an American brand, understanding US sizing is essential. A common point of confusion is that a US Queen is slightly smaller than a UK King, while a US King is significantly wider than a UK Super King. Always check dimensions before buying.
| US Size Name | Dimensions (cm) | Dimensions (inches) |
|---|---|---|
| Twin | 99 x 191 cm | 39" x 75" |
| Full / Double | 137 x 191 cm | 54" x 75" |

A Detailed Look at Each UK Bed Size: Who Is It For?
Choosing from the available bed sizes is about more than just dimensions; it’s about crafting a personal sanctuary tailored to your space and lifestyle. The right bed serves as the centrepiece of your room, defining its scale, comfort, and aesthetic. A well-chosen mattress not only promises rejuvenating sleep but also elevates the entire feel of your bedroom. To make an informed decision, consider how you sleep, who you share your bed with, and the room's proportions. This detailed breakdown will guide you towards the perfect foundation for your haven of comfort.
Compact Comfort: Single & Small Double Beds
Ideal for maximising space without sacrificing comfort, these smaller beds are clever solutions for modern living.
- Single (90 x 190cm): The quintessential choice for a child’s bedroom, a teenager's retreat, or a sophisticated guest room. A single bed offers ample room for one person while leaving plenty of floor space for furniture and daily life.
- Small Double (120 x 190cm): Often called a ‘Queen’ in the UK, this size is the ultimate upgrade for the solo sleeper. It provides that extra bit of luxurious space to stretch out, making it perfect for spare rooms or master bedrooms in stylish city apartments where space is at a premium.
The Nation's Favourite: The Standard Double Bed
The Double (135 x 190cm) remains the most popular bed size in the UK, and for good reason. It’s a versatile and balanced option that fits comfortably within the footprint of most standard bedrooms, making it a reliable choice for couples. However, it’s worth noting that this leaves just 67.5cm of space per person. For couples who value personal space or for taller individuals, a double can feel a little snug. For a deeper analysis of how personal space impacts sleep, this expert guide to mattress sizes offers excellent advice.
Ultimate Luxury & Space: King & Super King Beds
For those who believe a bedroom should be a grand escape, a larger bed is a non-negotiable investment in superior comfort and indulgence.
- King (150 x 200cm): Offering both extra width and length compared to a double, the King size is the gateway to truly undisturbed sleep. It provides ample room for couples to sleep without disruption and its generous proportions create a sense of opulence and grandeur in a master bedroom.
- Super King (180 x 200cm): The pinnacle of personal space and domestic luxury. A Super King bed transforms your bedroom into an escape worthy of a five-star hotel suite. With abundant room to relax, it’s the ultimate choice for unparalleled comfort and a truly restorative night’s sleep. Find the perfect linen for your luxury bed.
How to Choose the Right Bed Linen for Your Bed Size
Selecting the perfect bed is a significant decision. Once you have followed expert guidance on how to choose the right bed size for your room and personal comfort, the next step is to dress it in the finest linen. The name of your mattress-be it Double or Super King-is only the beginning. To achieve an impeccable fit and a truly luxurious feel, you must also consider factors like mattress depth and the desired drape of your duvet.
Fitted Sheets: It's All About the Mattress Depth
Modern mattresses, especially those with plush pillow-tops or when paired with a mattress topper, are often deeper than older models. A standard fitted sheet may not have enough fabric to tuck securely underneath, leading to corners slipping off during the night. To ensure a flawless fit, measure the depth of your mattress from the bottom seam to the top, including any toppers. We recommend choosing a sheet with a depth at least 5-7cm deeper than your mattress.
- Standard Fitted Sheets: Typically fit mattresses up to 30cm deep.
- Deep Fitted Sheets: Designed for mattresses up to 38cm deep.
- Extra-Deep Fitted Sheets: Offer a generous fit for mattresses up to 45cm deep.
Duvets & Duvet Covers: Creating a Luxurious Drape
For a sumptuous, hotel-style aesthetic, we always advise sizing up your duvet. A larger duvet provides a more elegant drape over the sides of the bed and eliminates any nightly battles for the covers. This simple change elevates the entire look of your bedroom, making your bed appear fuller and more inviting. Consider the following recommendations for an opulent finish:
- For a Double Bed: Choose a King Size Duvet (230 x 220cm)
- For a King Bed: Choose a Super King Size Duvet (260 x 220cm)
- For a Super King Bed: Choose an Emperor Size Duvet (290 x 235cm)
Pillows & Pillowcases: Completing the Look
The final touch to dressing your bed is selecting the right pillows. The size and number of pillows should complement the width of your mattress for a balanced, sophisticated appearance. Standard UK pillow sizes include Standard, King (or Super King), and Square. Ensure you match your pillow with the correctly sized pillowcase for a neat, tailored finish.
- Single & Double Beds: Two Standard pillows fit perfectly.
- King & Super King Beds: Two King pillows or three Standard pillows create a full look.

Measuring Your Space: A Practical Guide for the Perfect Fit
Selecting the perfect bed is a defining moment in crafting your bedroom sanctuary. While the comfort of the mattress is paramount, the physical dimensions are what truly integrate it into your space. To avoid the costly and disappointing mistake of choosing a bed that overwhelms your room or cannot be delivered, a few moments of careful measurement are essential. This simple guide ensures your new bed will be a source of pure comfort and elegance, not frustration.
Step 1: Map it Out in Your Bedroom
Before committing to one of the standard UK bed sizes, visualise its footprint directly in your room. Using masking tape, mark the bed's length and width on the floor where you plan to place it. This simple trick provides an immediate sense of scale. As a rule, aim to leave at least 60cm of clear walking space around the sides and foot of the bed. Remember to check for clearance with:
- Wardrobe and cupboard doors
- Opening drawers on chests and dressers
- Windows that open inwards
- The full swing of your bedroom door
Step 2: Consider Your Headboard and Bedside Tables
The listed dimensions of a bed frame rarely include the headboard, which can add significant depth. A grand, upholstered headboard might add an extra 10-15cm to the total length of your bed, so be sure to factor this into your floor plan. Ensure you also leave ample space on either side for your bedside tables, allowing you to access them comfortably. Finally, check the placement of power sockets to ensure your bedside lamps and chargers will reach without issue.
Step 3: Check Access Routes for Delivery
Your chosen bed must not only fit in your room but also get there. Take a moment to measure the width and height of all doorways, hallways, and stairwells on the delivery path. Pay close attention to tight corners or low ceilings. This is particularly critical for large, solid items like super king divan bases or one-piece headboards. Always check the packaged dimensions on the product page before finalising your order to guarantee a smooth and seamless delivery.
With these measurements in hand, you can confidently choose from the various bed sizes available, knowing you've planned for a perfect fit. This thoughtful preparation is the first step towards creating the tranquil, well-proportioned bedroom you deserve. Now, you are ready to explore our collection of premium beds and mattresses.

Frequently Asked Questions
What is the most popular bed size in the UK?
The Double bed remains the most popular and widely chosen size in the UK. Measuring 135cm x 190cm, it offers ample space for a single sleeper seeking extra comfort or a cosy fit for couples. Its versatility makes it a perfect fit for most standard bedrooms, striking a fine balance between spacious relaxation and efficient use of room space. This enduring popularity ensures a wide availability of luxurious bedding and stylish bed frames to complement it.
What is the difference between a UK King and a Super King bed?
The primary difference between these two luxurious options is width, which translates directly to personal sleeping space. A standard UK King size bed measures 150cm wide, while a Super King offers an expansive 180cm width. This additional 30cm (or one foot) provides an unparalleled level of comfort and personal room, making the Super King the ultimate choice for those who desire a truly spacious and undisturbed night's sleep, reminiscent of a five-star hotel suite.
Is a US Queen size bed the same as a UK King size?
No, they are not the same, and this is a common point of confusion for international shoppers. A US Queen size bed measures approximately 152cm x 203cm. In contrast, a standard UK King size is slightly narrower at 150cm but shorter at 200cm. While the widths are very similar, the length difference is notable. It is crucial to verify your measurements before purchasing bedding to ensure a perfect, elegant fit for your mattress.
Can I use a larger duvet on a smaller bed?
Absolutely. Choosing a duvet one size larger than your bed is a celebrated interior design secret for achieving a sumptuous, hotel-style aesthetic. For instance, using a King size duvet on a Double bed creates a more generous drape over the sides, enhancing the feeling of comfort and opulence. This ensures both partners are always comfortably covered and adds a look of plush, inviting luxury to your bedroom sanctuary. It is a simple way to elevate your sleep experience.
How do I measure my mattress depth for a fitted sheet?
To ensure our finest fitted sheets embrace your mattress perfectly, you must measure its depth accurately. Place a straight edge or ruler flat across the top of the mattress, then use a tape measure to record the distance from the bottom edge to the ruler. Do not compress any pillow top. For an impeccable fit, we recommend selecting a fitted sheet with a depth at least 5-7cm greater than your mattress to allow for a secure and smooth tuck underneath.
What size is an Emperor bed and do I need one?
An Emperor is one of the most magnificent options in our range of UK bed sizes, typically measuring a grand 200cm x 200cm (6ft 6" x 6ft 6"). This creates a vast, square sleeping surface that offers the pinnacle of luxury and space. An Emperor bed is an investment in ultimate comfort, perfectly suited for master suites with generous proportions where it can serve as a stunning centrepiece, promising an exceptionally lavish and undisturbed rest.
