There is a smaller bed size for couples: a double bed, which is 54 inches wide and 75 inches long (approx. 137 x 191 cm). which we will cover next.

Alternatively, if move transfer is a problem for you, you can try a split king. This has the same dimensions as an American king, but split into two mattresses of the same size, which sit next to each other on the same bed.

A split king may sound strange, but it's popular with couples who have very different sleep habits or hours of sleep (for example, if you work shifts). Since every mattress is different, this means that one person moving is less likely to disturb the other. On the other hand, the space between the mattresses can be uncomfortable if one or both of them roll to the middle. Also keep in mind that you will need special bedding.

US King vs. British King

While you might expect "king" to mean the same thing in the US and UK, they actually have different dimensions depending on which side of the Atlantic you live on. In terms of width, they're pretty similar: the UK King is just an inch narrower at 79 inches (200 cm) than the US King at 80 inches (203 cm). Where the two versions really differ, however, is in length. The US King is 76 inches (193 cm) long, while the UK King is more than 20 percent shorter at just 60 inches (150 cm).

How big is a king bed in the UK?

A UK king size bed is shorter than a US king size bed (see above). A British king is 60 inches wide and 79 inches long (or 150 cm wide and 200 cm long). That makes it a significant jump in size from a UK double bed, measuring 53 x 75 inches (or 135cm x 190cm), making it a great option for couples who like to spread out. and have plenty of bed space, especially when you often invite children or pets to come aboard.

If you want even more space, the next size is a UK Super King measuring 71 x 79 inches (or 180cm x 200cm). However, you need a fairly large room to accommodate a bed of this size, so for most couples, a king bed will be the sweet spot among the rooms you have.inthe bed and the room you havearoundbed.

What size is a super king size bed?

You only find a super king in Britain. It is the next step up in British actual height, measuring 71 inches by 79 inches (or 180 cm by 200 cm). That makes him 11 inches (30 cm) wider but no longer than a British king, who is 60 inches wide and 79 inches long (or 150 cm wide and 200 cm long). The closest US equivalent is the California King, which is only slightly larger at 72 x 84 inches (or 183 x 213 cm).

The super king bed is a good option for couples with money to spare who like to stretch out on their bed and have a large room to accommodate it. Conversely, most couples with standard-size bedrooms may not find enough space for a king-size bed, and a UK king-size bed is a more practical option.

Although the Super King is the largest of the standard UK sizes, that doesn't mean you can't buy bigger. Many brands and retailers sell oversized beds under names like "Caesar" or "Emporer." It's just that there's no industry-wide agreed-upon size convention or nomenclature for these larger beds.

As the name suggests, the California King (also known as the Cal King, CA King, or Western King) is found only in North America. The only way to see a bed with that moniker in the UK or Europe is to export it.

If you and your partner sleep differently or at different times of the night (for example, work shifts), you can get a split version of the California King. It has the same general dimensions, but is divided into two mattresses, each 90 cm wide, which are placed side by side. This minimizes motion transfer, although some find the gap between the mattresses uncomfortable when lying cross-bed on the bed.

A US king-size bed measures 76 inches wide and 80 inches long (approximately 193 cm wide and 203 cm long). A California king-size mattress measures 72 x 84 inches (183 x 213 cm), which is four inches narrower and four inches longer than a US king-size mattress. Because of this, it works well for couples where one or both are taller than average.

What size is a split king bed?

A split mattress is exactly what it sounds like. Instead of one big mattress, you get two separate mattresses placed side by side on the bed. For example, a split king bed has the same overall dimensions as a US king bed (76" x 80"), but consists of two 38" x 80" mattresses instead of one full-size.

Likewise, a split Cal King has the same dimensions as a Cal King (72" ​​x 84") but consists of two 36" x 84" mattresses instead of one full-size mattress.

Split mattresses are popular with couples where one partner tosses and turns throughout the night. In a normal bed, this would result in the transmission of motion through the mattress, waking the other partner. On a split mattress, however, they feel much less disturbing movement in bed.

Split mattresses also work best when one partner prefers a softer mattress and the other prefers a firmer one, as the two mattresses can have different levels of firmness. On the other hand, split mattresses require special sheets, and the space between the mattresses can be uncomfortable when you settle on them.
