When shopping for a new bed, one of the most common questions people ask is: How wide is a double bed? The answer might seem simple at first, but the truth is, bed sizes can vary depending on the country, the type of mattress, and even the manufacturer. If you’ve ever found yourself confused by different dimensions or wondering if a double bed is big enough for you, you’re not alone.
In this guide, we’ll break down everything you need to know about double bed dimensions, focusing specifically on UK standard sizes. We’ll also answer related questions like how big is a double bed?, how long is a double bed?, and how big is a standard double bed? So you can make an informed choice before investing in your next bed.
So, How Wide Is a Double Bed in the UK?
In the UK, the standard double bed measures:
- Width: 135 cm (4 feet 6 inches)
- Length: 190 cm (6 feet 3 inches)
That’s the official size for a UK double bed. It’s considered the most common bed size in British homes and often the default option when people say, “I want a double.”
So if you’re asking how wide a double bed is, the answer is 135 cm across, giving two people about 67.5 cm each—roughly the same width as a baby cot! This explains why some couples may find a double bed cosy, while others might prefer the extra space of a king-size or super king.
How Big Is a Double Bed Compared to Other Sizes?
To put the double bed’s size into perspective, let’s compare it with other standard UK mattresses:
- Small Double (Queen): 120 cm x 190 cm (4 ft x 6 ft 3 in) – Slightly narrower than a double, perfect for solo sleepers who want more space.
- Double: 135 cm x 190 cm (4 ft 6 in x 6 ft 3 in) – A balance between space-saving and comfort.
- King: 150 cm x 200 cm (5 ft x 6 ft 6 in) – Wider and longer, giving couples more breathing room.
- Super King: 180 cm x 200 cm (6 ft x 6 ft 6 in) – The ultimate in spacious luxury.
This comparison makes it clear: a double bed is a step up from a single, but still compact compared to larger options.
If you’re still wondering how big a double bed is, think of it as a practical choice for average-sized bedrooms and couples who don’t mind sleeping a little closer.
How Long Is a Double Bed?
In the UK, the standard double bed length is 190 cm (6 feet 3 inches).
This length works well for most adults, but if you’re particularly tall (over 6 ft 2 in), you might feel cramped. In that case, you’ll want to look at a king-size bed (200 cm long) or even a super king for extra comfort.
We’ve broken down these measurements in detail in our bed size guide, so you can quickly compare and see which one suits your height and room size.
How Big Is a Standard Double Bed in a Room?
Knowing the measurements of a double bed is one thing—but understanding how it will fit into your bedroom is another.
Here are a few quick tips when planning your space around a double bed:
- Leave Walking Space: Ideally, keep at least 60 cm of clearance around the bed so you can move comfortably.
- Measure Your Furniture: Consider bedside tables, wardrobes, or dressing tables before committing.
- Think About Storage: If your bedroom is tight, opt for an ottoman or divan base with drawers for hidden storage.
A standard double bed is a versatile option for bedrooms sized 3 x 4 metres (10 x 13 feet) or larger. In smaller rooms, it might feel a little snug, but with the right layout, it’s still manageable.
Who Is a Double Bed Best For?
A double bed is ideal if:
- You’re a solo sleeper who enjoys extra space to stretch out.
- You’re a couple living in a smaller flat or home and need a bed that balances comfort with practicality.
- You’re furnishing a guest bedroom where you want a comfortable option that doesn’t take up too much floor space.
- It’s essentially the “middle ground” of beds—bigger than a single but not quite as luxurious as a king.
Should You Choose a Double Bed?
The real question isn’t just how wide a double bed is, but whether that width suits your needs. Here are a few things to think about:
- Room Size: Will a double bed leave enough walking and storage space?
- Sleeping Style: Are you a still sleeper, or do you and your partner need more room to roll?
- Future-Proofing: If you’re moving soon or upgrading, would it make sense to invest in a king instead?
