Quick reference: queen dimensions at a glance

Seven key measurements — one pattern: queen mattresses are not a single global standard. The table below pulls together the most common regional sizes so you can spot the differences instantly.

What this means: a queen in the US is actually slightly narrower but longer than the European queen. An Irish king is narrower still, so never assume a “queen” label matches the US standard.

What is the size of a queen size mattress?

Queen size mattress dimensions in the United States

• The standard US queen measures 152 cm × 203 cm (60″ × 80″) as defined by the International Sleep Products Association (Amerisleep – industry standard chart).
• It is 6 inches wider and 5 inches longer than a US full/double mattress (Amerisleep comparison).
• Queen accounts for about 47% of all mattress sales in the United States (Amerisleep market data).

Queen size mattress dimensions in the United Kingdom and Ireland

• The common queen size in the UK and Ireland is 160 cm × 200 cm (63″ × 79″) (Wikipedia – UK bed sizes).
• This is 8 cm wider and 3 cm shorter than the US queen.
• Some Irish retailers also sell beds labelled “queen” that measure 150 cm × 200 cm, which is actually the Irish king size (Casper size guide).

Queen size mattress dimensions in Europe (metric)

• The European standard queen is 160 cm × 200 cm, identical to the Irish/UK queen (PureCare global mattress chart).
• This size is widely used across continental Europe for double-bed frames.

The implication: there is no single “queen” dimension. Your local retailer’s definition may differ from the one you saw on an American website. Always check the exact metric size.

Is a queen bigger than a double-size bed?

UK double bed dimensions

• The standard UK double is 135 cm × 190 cm (4′6″ × 6′3″) (Wikipedia – double bed).
• It is the smallest width that comfortably sleeps two adults.

US double (full) bed dimensions

• The US double (also called full) measures 137 cm × 190 cm (54″ × 75″) (Casper mattress size comparison).
• It is 2 cm wider and the same length as the UK double.

Queen vs double width and length comparison

• A US queen is 15 cm (6″) wider and 13 cm (5″) longer than a US double (Amerisleep).
• A UK queen is 25 cm (10″) wider and 10 cm (4″) longer than a UK double.
• When shared, a queen offers about 30 inches of personal space per person, vs 27 inches on a double (Nectar Sleep space analysis).

The pattern: queen beats double in both width and length in every region. For couples, the extra 15–25 cm width means significantly better sleeping space.

Is 160×200 cm a queen size bed?

Common queen size in Europe and Ireland

• Yes — 160 cm × 200 cm is the standard queen size across Ireland, the UK, and most of Europe (PureCare global chart).
• It is the same as the UK queen and the European double.

Difference between 160×200 cm queen and 150×200 cm king

• Irish king beds are 150 cm × 200 cm — that is 10 cm narrower than the European queen (Wikipedia – Irish sizes).
• This is the opposite of the US, where king is wider than queen.
• The confusion arises because some Irish retailers sell a 150 cm × 200 cm bed as “queen” when technically it matches the Irish king dimension.

“Queen size is primarily in North America; the Irish equivalent is often 150×200 cm.” — DFI Beds guide

The trade-off: if you buy a “queen” mattress from an Irish store without checking the fine print, you could end up with a bed that is 10 cm narrower than the European standard — and your sheets might not fit.

What is the size of a queen bed in Ireland?

Irish queen mattress dimensions in cm and inches

• The most common Irish queen size sold in stores is 160 cm × 200 cm (63″ × 79″) (IKEA Ireland mattress size guide).
• IKEA Ireland lists this size as “Queen” in their standard size chart.
• However, independent retailers sometimes use 150 cm × 200 cm for queen, leading to inconsistency.

How Irish queen compares to UK and US queen sizes

• Irish queen (160×200) is 8 cm wider and 3 cm shorter than US queen (152×203).
• Irish queen is the same as UK queen (160×200).
• Irish king (150×200) is actually narrower than Irish queen — a reversal of the US naming convention.

The catch: Ireland’s inconsistent queen labelling means consumers cannot rely on the name alone. The only safe way is to read the specification sheet.

What mattress fits a queen size bed?

Matching mattress to queen bed frame

• The mattress must match the internal dimensions of the bed frame exactly — a 160 cm wide mattress won’t fit a 152 cm wide frame.
• Queen mattresses are available in pocket sprung, memory foam, and hybrid constructions.
• Measure your bed frame (width and length) before ordering, especially if buying online.

Important: confirm exact dimensions before purchase

• Returns on wrong-size mattresses are expensive and often not covered by warranty.
• If your frame was purchased in Ireland, the safest queen size is 160 cm × 200 cm.
• For US-imported frames, use 152 cm × 203 cm.

“Queen size in Europe is standardised at 160×200 cm, but always double-check the manufacturer’s label.” — IKEA Ireland mattress size guide

The implication: never blindly order a queen mattress. Know whether your frame conforms to the US, European, or local Irish standard — or risk a costly mismatch.

Clarity: what’s confirmed and what’s still unclear

For Irish shoppers, the safest approach is to look up the exact product dimensions — not the name — on the retailer’s website.

Frequently asked questions

For anyone buying a queen mattress in Ireland, the choice is clear: either stick with the European standard of 160 cm × 200 cm, or measure your frame first. Guessing the label costs time, money, and a good night’s sleep.
