UK Standard Bed Sizes and Dimensions

One of the most common questions we have been asked over the years is ‘what size is a king size bed?’  This confusion is however not limited to just one bed size.

The following bed size information to clear up the confusion caused by the different names that are used to refer to different bed sizes.  Much of the confusion is caused from European and American sizes and terminology being very different from that of our own. 

So to confirm, this information relates to the sizes quoted of standard UK bed sizes. Please note, some manufacturers make to metric sizes and others to imperial sizes therefore we have shown the metric conversion in brackets

What size is a Small Single bed?    75 x 190 cm    /    30" x  75"    /    2'6" x 6'3"

A standard small single bed is the same length as a single mattress, but is 6 inches narrower, measuring 2 feet 6 inches wide (76 x 191cm).  This is a popular size when trying to save space in a smaller room or for toddlers moving from a cot bed.

What size is a Standard Single bed?    90 x 190 cm    /    36" x 75"    /    3' x 6'3"

A standard single bed is 3 feet wide and 6 feet 3 inches long (91 x 191cm).  This is the most common bed size for children, kids beds and bunk beds.

What size is a Small Double bed?    120 x 190 cm    /    48" x 75"    /    4' x 6'3"   

A small double bed refers to a 4 feet wide, 6 feet 3 inches long mattress (122 x 191 cm).  This represents a mattress 6 inches narrower than a standard double mattress.  Over the last 5 years the popularity of this size has become much greater for use in spare rooms or for teenagers to give a larger sleeping area without taking over all the available space in the room.

What size is a Standard  Double bed?    135 x 190 cm    /    54" x 75"    /    4'6" x 6'3

A standard double bed is 4 feet 6 inches wide and 6 feet 3 inches long (137 x 191 cm).  This is the most common and widely available size for all bed types in the UK.

What size is a King bed?    150 x 200 cm    /    60" x 78"    /    5' x 6'6"

A standard king size bed is 5 feet wide and 6 feet 6 inches long (152 x 198 cm).  Please note: from a king size bed and upwards the standard length increases by 3 inches to 6 feet 6 inches or about 2 metres.  This is the size we will always recommend to taller customers to save having their toes hanging out the end of the bed!

What size is a Super King bed?    180 x 200 cm    /    72" x 78"    /    6' x 6'6"

A super king size bed is 6 feet wide and 6 feet 6 inches long (183 x 198 cm).  Please note: from a king size bed and upwards the standard length increases by 3 inches to 6 feet 6 inches or about 2 metres.  This is the size we will always recommend to taller customers to save having their toes hanging out the end of the bed!

What size is a Queen bed?    152 x 203 cm    /    60" x 80"    /    5' x 6'8"

The Queen size terminology is another taken from the American market.  A Queen size bed in the US refers to a 60 inch wide by 80 inch long mattress (152 x 203 cm), although it is more commonly referred to in the UK as a ‘ King’ instead being of similar dimension.

What size is a Twin bed?

A Twin bed is an American term used for a mattress slightly wider than a single bed measuring a metre wide.  It is not a terminology that is used widely within the UK as this does not represent any of the UK standard bed sizes.   

Please note: these sizes represent the size of a mattress or a divan.  Any bed frames will be slightly larger to accommodate the mattress sitting inside the frame.  There may also be slight differences in the dimensions depending on the individual manufacturer and the finish of the product.
