Modern manufacturing conventions have resulted in a limited number of standard sizes of commercial bedding for full size mattresses and box springs. They vary by country of origin. This mattress comparison table can help you to decide which size bed you should get for your height.

The standard bed sizes in the UK and Ireland, other than the double, vary compared to the US sizes, being generally smaller. The US queen corresponds to UK king bed, and king to super king. The European or continental basic sizes are similar to the UK but have a set length of 200 centimetres. The terms queenking and super king are not used in continental Europe, and double refers to 140 cm or any higher width. Instead of these US/UK denominations, the bed width is given in centimetres.

These bed dimensions are for mattress sizes—the actual bed frame will be a little bigger in order to fully encompass and support the mattress. The thickness of the mattress may vary considerably.

Most mattress sizes in the Netherlands are also available in extra long, meaning 220 cm instead of 200 cm.

In the Scandinavian countries, standards vary from one country to another. In Norway, these sizes are used:

Small single
75 cm × 200 cm (30 in × 79 in)
Single
90 cm × 200 cm (35 in × 79 in)
Large single
120 cm × 200 cm (47 in × 79 in)

Queen
180 cm × 200 cm (71 in × 79 in — equal to two single mattresses)

Beds/mattresses are often available also in extra long (220 cm or 87 in length). Some older beds are only 190 cm (75 in) long, while antique beds often are even shorter (since they in older times often slept in a reclined position rather than the close to supine position which is common today, and also, on average, people are taller now than they used to be).
