Bed & Mattress Sizes in Ireland

When choosing a bed for your bedroom, size matters! Finding the right bed and mattress size for you and for the space you have available is essential. Mattress sizes tend to differ between countries, which can make it confusing when researching different bed size options.

DFI Beds has put together an A-Zzzz of bed and mattress sizes in Ireland to make the process easier and ensure you get the right mattress and bed for you.

What is the best size of bed for your bedroom?

Determining the best size of bed for your bedroom is down to two things: available space and personal preference. We’ve outlined the standard dimensions for bed and mattresses in Ireland in the handy table below:

Dimensions (cm)  Dimensions (Feet & Inches)
Super King 180cm x 200cm  6'0" x 6'6"
King 150cm x 200cm  5'0" x 6'6"
Standard Double 135cm x 190cm  4'6" x 6'3"
Small Double 120cm x 190cm  4'0" x 6'3"
Single 90cm x 190cm  3'0" x 6'3"
Small Single 75cm x 190cm  2'6" x 6'3"

First things first

  • Using a measuring tape, size up your bedroom or available space
  • Make sure the mattress size you choose can fit comfortably in the space
  • Factor in additional space each side of the bed if you use bedside lockers
  • If you’re sizing a mattress for an existing bed frame, make sure the length and width of the bed frame and mattress is the same

What size is a Super King size bed and mattress?

The standard dimensions of a super king bed and mattress in Ireland are 180cm wide x 200cm long. Or 6ft wide x 6ft 6in long. As the name would suggest, the Super King is the daddy of all mattresses and the largest bed and mattress size available from DFI Beds. This is sometimes referred to as a 6 foot bed.

If you’re looking for a serious amount of prime sleeping real estate or if you value having a bit of extra personal space in bed, the super king will have you covered. With more than enough room for two people, it will easily accommodate additional small family members and pets for weekend morning snuggles.

What size is a King size bed and mattress?

A standard king size bed and mattress is 150cm wide and 200cm long or, in imperial dimensions, 5 feet wide and 6 feet 6 inches long.

Sometimes referred to as a 5 foot bed, a King size mattress offers ample space for two people and is ideal for taller people. As the height of the average Irish person is a mere 5 feet 7.72 inches, the king size should offer more than enough legroom for the average individual. And if you’re over 6 foot 2, this is definitely the bed for you!

What size is a Double bed and mattress?

Measuring in at 135cm wide and 190cm long or 4 feet 6 inches wide and 6 feet 3 inches long in imperial dimensions, the double bed and mattress is the most common size for a bed in Ireland and one you’re likely all familiar with.

A standard double offers enough room for two people to sleep comfortably, and works well for those with limited space in the bedroom. In a recent sleep survey conducted by DFI Beds, a majority of respondents (47.35%) stated their current bed was a double.
