What is the Best Bed Size For Your Bedroom?

Choosing the right bed frame size in Ireland comes down to determining how much space you have and how much space you want your bed to take up. 


Grab a measuring tape. Measure the room or area you want the bed to occupy, ensuring the sizing makes sense. Make sure you remember to take into account space for bedside lockers and other furniture as needed.

How to Make Sure You Have Enough Space for the Mattress?

To measure what bed size you can select from, you want to ensure you have enough space. This means that you’ll want to begin by taking measurements of your dedicated space. 


If you think it’s time to update your mattress for an already existing bedframe, measure the length and width of the bedframe where the mattress will go. This ensures you purchase the right one!

What Size is a Super King Size Bed and Mattress?

A typical Super King bed size is 6ft in Ireland, such as this beautiful Cliona Bed Frame, measures 180 cm across by 200 cm long. 180 cm in feet is 6’0”, and 200 cm in feet is 6’6”. 


Sometimes called a 6-foot bed, this is the biggest size mattress or bed in Ireland, offering plenty of space for two people to sleep comfortably, plus any children or furry friends who want to join.

What Size is a Super King Size Bed and Mattress?

King-size bed dimensions typically are 150 cm across by 200 cm long or 5’0” by 6’6”. This is where you’ll hear the phrase “5-foot bed” used. This king bed size also offers ample space for two people, even accommodating those over 6’2”.


If you’re looking for a king-size bed frame, the Caoimhe Bed Frame is simple yet timeless.

What Size is a Double Bed and Mattress?

Double bed sizes in Ireland typically are 135 cm across and 190 cm long, or 4’6” by 6’3”. While you can get a small double bed size, the standard double bed is the most commonly used mattress and bed in the country. 

If you have minimal space in your bedroom but still require room for two people, the double bed likely fits the bill. For a high-quality double bed, check out the Lombardy Bed Frame from Casey’s.

Small double bed sizes in Ireland have slightly less room than the standard double bed, measuring 120 cm across and 190 cm in length or 4’0” by 6’3”. 

This size bed or mattress is best for one person who loves their space as they sleep, such as the double-size Aoibheann Slatted Bedstead. This is also a great option for older kids, teens, and young adults.

What Size is a Single Bed and Mattress?

Single bed sizes in Ireland, such as the Saoirse Bed Frame from Casey’s, come in at 90 cm in width and 190 cm in length or 3’3” by 6’3”.


When deciding on kid’s furniture, this size bed is best for children. It also fits a room with very limited space, such as if you want to add a bed to an office space or other small room to accommodate guests.

What Size is a Queen Size Bed and Mattress?

Queen bed sizes in Ireland aren’t standard. These measure 5’0” wide and 6’8” long, making a queen size bed about two inches longer than the traditional king bed sizes in Ireland. Since these are not common mattress sizes in Ireland, it’s rare to find these on the Irish market.

How to Match Your Mattress to Your Bed Size in Ireland?

While you always want to measure your bed frame and fit the mattress from there, most Irish bed sizes will have a matching memory foam or pocket-sprung mattress. The one you chose may depend on your personal preference and budget.
