Hotel-style mattress toppers are cut to the same five standard sizes as Australian mattresses: Single (92 x 188 cm), King Single (107 x 203 cm), Double (138 x 188 cm), Queen (153 x 203 cm) and King (183 x 203 cm). The label size refers to the mattress it's designed to sit on, not the finished sleeping surface — a topper with an elasticated skirt or boxed hotel-style corners pulls in a few centimetres once it's fitted, so always size to your mattress, never to the room or the bed frame.
- Queen mattress toppers measure 153 x 203 cm in Australia, matching queen mattress dimensions exactly.
- King and Queen are the two most requested hotel-style topper sizes for Australian main bedrooms in 2026.
- Elasticated skirts and boxed corners pull toppers a few centimetres smaller than the label size once fitted.
- Single and King Single are not interchangeable — a 15 cm width gap means a Single topper won't cover a King Single mattress.
- Match topper size to mattress size first, then check pocket depth against your mattress profile.
Why this matters
A mismatched topper is the single most common reason a hotel-style bed setup looks sloppy at home — it bunches at the corners, slides off centre overnight, or leaves a gap that lets cold air in along one edge. Getting the size right the first time means the topper sits flush under your fitted sheet the way it does in a five-star room, with no shifting and no visible lip. Elegante's how to pick mattress topper size guide covers the fitting mechanics in more depth; this page is the quick reference for matching the number on the label to the bed you actually own.
What size mattress topper do I need for my bed?
Check your mattress dimensions against the table below before you buy — Australian bed sizing is standardised, so a topper labelled for your mattress size will fit unless your mattress is a custom or imported non-standard depth.
| Bed size | Topper dimensions | Best for |
|---|---|---|
| Single | 92 x 188 cm | Kids' rooms, single guest rooms |
| King Single | 107 x 203 cm | Teen bedrooms, taller single sleepers |
| Double | 138 x 188 cm | Smaller guest rooms, studio apartments |
| Queen | 153 x 203 cm | Main bedrooms, most common Australian size |
| King | 183 x 203 cm | Master suites, couples wanting extra width |
Verdict: measure your mattress, not your room — a Queen topper will not stretch to cover a King mattress even though the difference looks small on paper (30 cm of width).
Single mattress topper: 92 x 188 cm
A Single topper covers a 92 x 188 cm mattress and is the right call for kids' rooms, single guest rooms, or a compact home office daybed. It's the narrowest of the five standard sizes, so double-check your mattress isn't actually a King Single before ordering — the two look similar in a small room but differ by 15 cm in width. Buy for any true single mattress; skip if you're not certain of the exact mattress width.
Double mattress topper: 138 x 188 cm
A Double topper fits a 138 x 188 cm mattress, the size still common in older Australian homes and share-house guest rooms. It shares the same 188 cm length as a Single but adds 46 cm of width, so it suits couples in smaller footprints or a single sleeper who wants more room to move. Buy for a genuine double mattress in a guest room or smaller main bedroom; hold if you're planning a mattress upgrade to Queen soon, since the topper won't carry over.
Queen mattress topper: 153 x 203 cm
A Queen topper measures 153 x 203 cm and is the most common size ordered for Australian main bedrooms in 2026. It adds 15 cm of length over Double and Single sizes, which matters for taller sleepers, and its width comfortably fits two adults. This is the size most hotel-style bedding sets are built around, including layered quilt-and-topper combinations. Buy for most standard main bedrooms — it's the safest default when in doubt about which size to order.
King mattress topper: 183 x 203 cm
A King topper is 183 x 203 cm, 30 cm wider than Queen but the same 203 cm length. It's built for master suites where two adults want dedicated space, and it's the size most often paired with a feather-filled topper for a genuinely plush, hotel-grade sleep surface — the hotel mattress topper in Elegante's range is finished in 1550gsm feather and down and sized to King and Queen mattresses. Buy for master bedrooms wanting the full five-star feel; skip if your bed frame is a Queen frame, since a King topper won't sit flush on a narrower base.
Why mattress topper sizing varies
A handful of factors push a topper's actual fit away from the label size once it's on the bed:
- Fill type — feather and down toppers loft higher than foam or wool, which changes how the topper drapes over the mattress edge.
- Elasticated skirt depth — a deeper skirt pulls the topper's footprint in slightly tighter than the flat label dimensions.
- Boxed hotel-style corners — these hold the topper square on the mattress but reduce overhang compared with a simple flat topper.
- Mattress depth variation — pillow-top and pocket-spring mattresses run deeper than standard innerspring, and a shallow skirt won't reach.
- Custom or imported mattresses — non-standard depths sold outside the five Australian sizes need a topper checked against actual measurements, not the size name alone.
For a full breakdown of pocket depth and fill height, choosing mattress topper thickness is worth reading before you order, especially if your mattress is deeper than a standard innerspring.
Can I use a Queen topper on a King mattress?
No — a Queen topper is 153 x 203 cm and a King mattress is 183 x 203 cm, a 30 cm width gap that leaves one whole side of the mattress exposed. Buying by the size printed on your mattress tag, not the bed frame name, avoids this mismatch entirely.
Does a hotel-style topper fit a pillow-top mattress?
A hotel-style topper fits a pillow-top mattress as long as the skirt or strap depth is generous enough to clear the pillow-top's extra height, since pillow-top mattresses sit deeper than a standard flat-top mattress. Check the topper's skirt depth against your mattress's total depth, including the pillow-top layer, before ordering.
Is Queen or King the better default size for a main bedroom?
Queen (153 x 203 cm) is the more common size for single main bedrooms in Australian homes in 2026, while King (183 x 203 cm) suits master suites where two adults want more shoulder room. Neither is objectively better — it comes down to the mattress you already own, since a topper has to match that size exactly.
A well-fitted topper is one part of the full hotel-bed setup — layering it under a hotel-style sheet set finishes the look the way a five-star room does, provided both pieces are ordered in the same mattress size.
FAQ
What size mattress topper do I need for a Queen bed?
A Queen mattress topper measures 153 x 203 cm in Australia, matching a Queen mattress exactly. Always confirm your mattress tag reads Queen before ordering, since Queen and King differ by 30 cm in width.
Is a King Single topper the same as a Single topper?
No, a King Single topper is 107 x 203 cm while a Single topper is 92 x 188 cm — a 15 cm width and 15 cm length difference. The two are easy to confuse in a small room but are not interchangeable.
How much smaller is a topper once it's fitted with an elastic skirt?
An elasticated skirt or boxed corner pulls a topper a few centimetres tighter than its flat label dimensions once fitted. This is a fitting allowance, not a sizing error, and applies across all five standard Australian sizes.
Do mattress toppers come in King Single size?
Yes, King Single toppers measure 107 x 203 cm and are sized for King Single mattresses common in teen bedrooms and taller single sleepers' rooms. They are not a substitute for Double or Queen sizing.
Can I use a Double topper on a Queen mattress?
No, a Double topper is 138 x 188 cm and a Queen mattress is 153 x 203 cm, leaving both width and length uncovered. Order strictly by the size printed on your mattress tag.
What size topper fits a King mattress?
A King mattress needs a King topper at 183 x 203 cm, the widest of the five standard Australian sizes. King toppers suit master suites where two adults want extra width across the bed.
Does mattress depth affect which topper size I need?
Mattress depth affects skirt or strap length, not the flat topper dimensions, so a deep pillow-top mattress still needs the same length and width topper as a standard mattress of the same name. Check skirt depth separately from length and width when your mattress runs deeper than standard.
One last thing
The size gap between Queen and King (30 cm in width) is bigger than most people expect when they're eyeballing a bed from across the room — measure the actual mattress tag before ordering rather than guessing from the bed frame name. It's the single most common return reason for mattress toppers, and it's avoidable with one measurement.
