Anyone who has ever bought a bed in Ireland knows the confusion that hits when a mattress labelled “double” doesn’t fit the frame you brought home. Standard dimensions vary across borders, and the difference between an Irish double (135 x 190 cm) and a European double (140 x 200 cm) is small enough to cause big headaches. This guide lays out the exact measurements, explains why that 140 x 200 cm bed you saw online is not an Irish double, and gives you the facts to buy with confidence.

Four standard double sizes, one pattern: Ireland and the UK share the 135 x 190 cm standard, while continental Europe uses a wider, longer bed at 140 x 200 cm. The implication: if you buy a “double” from a European retailer online, it likely won’t fit an Irish bed frame.

How does the Irish double compare to UK double?

The upshot

Irish and UK doubles are the same size, which means cross-border buyers from Britain face no fit surprises. The real mismatch happens when shoppers import a European double from mainland Europe or IKEA’s continental range.

The pattern: Ireland’s bed sizing follows the UK tradition, not the continental European standard. Why this matters — buying a “double” mattress from a French or German online store will land you a 140 x 200 cm bed that is 5 cm wider and 10 cm longer than your frame.

Five centimetres of extra width and ten extra centimetres of length — that gap is enough to make a fitted sheet slip off or a duvet hang unevenly. The trade-off: if you prefer a bit more legroom, the European double (140 x 200 cm) offers that, but you’ll need a frame built to match.

Is 140×200 cm a double bed?

140×200 cm as a European double

  • Yes, in continental Europe 140 x 200 cm is the standard double bed size (The Sleep Shop – Guide to Mattress Sizes).
  • IKEA markets 140 x 200 cm as a “European double” in Ireland, distinguishing it from the 135 x 190 Irish double (IKEA Ireland mattress size guide).

Why 140×200 cm is not an Irish standard double

  • In Ireland, the standard double is 135 x 190 cm — not 140 x 200 cm (Dochara – US vs Irish bed sizes).
  • Buying a 140 x 200 cm mattress for a 135 x 190 cm frame means the mattress will overhang on all sides and the bed frame will not support it properly (DFI Beds – Fit warnings).
The catch

A 140 x 200 cm mattress is technically a double — but not in the Irish system. If you see “double” on a European product page without checking the cm, you risk buying a bed that won’t sit inside your existing Irish frame.

What this means: a 140 x 200 cm bed is the correct double size for a bedroom in Berlin or Paris, but in Dublin or Cork it is a mismatch that requires a specialty frame and sheets.

What does “double” mean in Irish hotels?

  • Most Irish hotels and B&Bs use 135 x 190 cm double beds (Dochara – Irish hotel bed sizes).
  • Some budget hotels may use small double (120 x 190 cm) in compact rooms, but the standard advertised double is 135 x 190 cm (DFI Beds – Irish hotel sizing).

Whether you book a room in Galway or buy a bed in Belfast, “double” means the same 135 x 190 cm size. The implication: it keeps the sheet and duvet market standardised, meaning any Irish bedding set fits any Irish double bed.

What are other common bed sizes in Ireland?

Small double bed size in cm Ireland

  • Small double (4ft): 120 cm wide by 190 cm long (The Sleep Shop – Guide to Mattress Sizes).
  • This is narrower than the Irish standard double by 15 cm (DFI Beds – Small double sizing).
  • Sometimes marketed as a compact double for guest rooms or single occupancy with extra space (Dochara – Small double in Ireland).

King bed size in cm Ireland

  • King size in Ireland: 150 cm wide by 200 cm long (Gotta Sleep – King size dimensions).
  • This is 5 ft by 6 ft 6 in and is wider than a standard double by 15 cm (Beaumont Brown – King size guide).

Single bed size in cm Ireland

  • Single bed in Ireland: 90 cm wide by 190 cm long (The Sleep Shop – Single mattress size).
  • This is 3 ft by 6 ft 3 in, standard across the UK and Ireland.
Size type Width (cm) Length (cm) Width (inches) Length (inches) Common use
Single 90 190 3 ft 0 in 6 ft 3 in Children, guest rooms
Small double (4ft) 120 190 4 ft 0 in 6 ft 3 in Compact doubles, solos

European double 140 200 4 ft 7 in 6 ft 6 in Continental market, IKEA
King (Irish) 150 200 5 ft 0 in 6 ft 6 in Master bedrooms
Super king (Irish) 200 200 6 ft 6 in 6 ft 6 in Large master bedrooms

Six bed sizes, one rule: Ireland stays consistent with UK dimensions, and the European double at 140 x 200 cm is the only size that doesn’t align. The pattern — know which double you’re buying, and the sheets will fit.

What bed size is 240×220 cm?

Super king or custom size

  • 240 x 220 cm is a custom or super king size, not a standard double (Gotta Sleep – Custom sizes explained).
  • The standard super king in Ireland is 200 x 200 cm, which is smaller than 240 x 220 cm (DFI Beds – Super king sizing).

Is 240×220 cm available in Ireland?

  • Most Irish retailers do not stock 240 x 220 cm as a standard size (IKEA Ireland – standard sizes list).
  • Custom bedding and frames would be required for this dimension (The Sleep Shop – Custom sizes).

240 x 220 cm is not a standard Irish double bed size. If you need that space, you will have to order a custom frame and mattress — and expect to pay a premium for both.

Which bed size is 180×200?

180×200 cm as a European king

  • 180 x 200 cm is a European king size, not a double (Gotta Sleep – European king dimensions).
  • In Ireland, king size is 150 x 200 cm and super king is 200 x 200 cm (Beaumont Brown – King vs super king).

Does 180×200 cm exist in Ireland?

  • IKEA sells 180 x 200 cm as a king in some European markets but not in Ireland (IKEA Ireland mattress size guide).
  • In Ireland, 180 x 200 cm is not a standard size — you would need a custom frame and sheets (DFI Beds – Custom dimensions).
The trade-off

A 180 x 200 cm bed offers more width than an Irish king (150 cm) but falls 20 cm short of a super king (200 cm). For Irish buyers, it means custom everything — frame, mattress, linens — and no guarantee of fit with standard Irish bedding.

The pattern: 180 x 200 cm is a common European size that sits between Irish king and super king, but it is not stocked as standard in Ireland. The implication — Irish shoppers should stick to local sizing unless they are willing to source custom everything.

The only exception is IKEA’s European double line at 140 x 200 cm, clearly labelled as such. For the Irish shopper, the choice is straightforward: buy the size that matches your frame, and confirm the cm before you click.

Frequently asked questions

What is the standard double bed size in Ireland?

135 cm wide by 190 cm long (4 ft 6 in x 6 ft 3 in). This matches the UK standard and is sold by IKEA Ireland, DFS Ireland, and most independent retailers (IKEA Ireland mattress size guide).

Is a double bed in Ireland the same as in the UK?

Yes — both share the 135 x 190 cm standard. There is no practical difference between a double bed bought in Dublin and one bought in London (Beaumont Brown – Guide to Bed Sizes UK, Europe and USA).

What is the difference between a double and a small double in Ireland?

A standard double is 135 x 190 cm, while a small double (4ft) is 120 x 190 cm — 15 cm narrower. The small double fits smaller rooms but still accommodates one adult comfortably (DFI Beds – Small double sizing).

Can I use a European double (140×200) sheet on an Irish double (135×190) bed?

Fitted sheets for 140 x 200 cm will be too large — they will bunch and slip off a 135 x 190 cm mattress. Flat sheets and duvets may also hang unevenly. Always match sheet size to the exact mattress dimensions (The Sleep Shop – Sheet fit guide).

Where can I buy a double bed in Ireland that fits standard sheets?

IKEA Ireland, DFS Ireland, Harvey Norman Ireland, and independent mattress shops all stock the 135 x 190 cm double. Look for “Irish double” or “UK double” on the label — and always check the cm (IKEA Ireland mattress size guide).

Do Irish hotels use 135×190 double beds?

Most do. Standard double rooms in Irish B&Bs and 2–3 star hotels use 135 x 190 cm beds. Higher-end hotels may use king or super king, but standard double means 135 x 190 cm (Dochara – Irish hotel bed sizes).

What is the most common double bed size sold in Ireland?

The 135 x 190 cm double is the most common size for two-person beds. For single occupancy, the small double (120 x 190 cm) is also popular in compact homes and guest rooms (DFI Beds – Most common sizes in Ireland).

For the Irish shopper, the choice is clear: stick with the 135 x 190 cm standard double, or deliberately switch to a European double (140 x 200 cm) only after confirming that your frame, sheets, and duvet are compatible. Otherwise, you risk a bed that fits in neither your frame nor your linen cupboard.
