How big is a king size bed?

King size bed dimensions

A king size bed frame is designed to hold a king size mattress, which measures 5'0" (150cm) wide by 6'3" (190cm) long. However, the dimensions of king size bed frame can vary depending on whether the design has incorporated a headboard, footend or other features that could alter the measurements. Within each product, you'll be able to view what size it is under the specifications tab. Whether your bedroom is large enough to accommodate one of our king size mattresses and bed frames should be an important consideration before purchase. If you're conscious of your room's available space, a double bed is a fantastic space-saving alternative.

Your new bed frame - king or super king size?

In truth, the likelihood is that if your bedroom is large enough to accommodate a king bed frame, a super king bed frame is also likely to be a suitable fit. For context, our super king size bed frames measure 6'0"(180cm) wide and 6'6" (200cm) long. If you're conscious of your room's available space, consider a king or super king size bed with storage capabilities.
