Queen Size Blanket Dimensions & Every Bed Size in cm

A standard Australian queen size blanket measures roughly 240 × 260 cm, giving enough coverage to drape a queen mattress (153 × 203 cm) with an even overhang on both sides and at the foot. Blanket dimensions vary a little between manufacturers, but the pattern is the same: a blanket should sit around 40 to 60 cm wider than your mattress and 30 to 50 cm longer, so it doesn't ride up when you move. Below, we cover every AU bed size in cm, plus how blanket sizes compare to doonas and quilts.

Key Takeaways

• A queen size blanket in Australia measures around 240 × 260 cm, sized to drape a queen mattress (153 × 203 cm) with a comfortable overhang.

• Blanket sizes are generally 40 to 60 cm wider and 30 to 50 cm longer than the mattress, which gives coverage across both sides and enough length to tuck under the foot.

• Doonas and quilts follow a different sizing convention to blankets, usually described in W × L cm (e.g. queen doona ~210 × 210 cm), and are designed to sit on top of the mattress rather than drape down each side.

• Match blanket size to mattress size, not bed frame size, because bed frames add width beyond the mattress but blankets are cut for the mattress dimensions.

• King blankets are noticeably wider than queen blankets to cover the extra 30 cm of mattress width, so upsizing from queen to king means a genuinely larger blanket, not just a longer one.

Standard Blanket Dimensions by Bed Size (Comparison Table)

Standard Australian blanket dimensions run from around 180 × 240 cm for a single up to 270 × 270 cm for a king, sized to drape the mattress with enough overhang on both sides and at the foot. Exact dimensions vary between manufacturers (blankets aren't standardised the way mattress sizes are), so use the ranges below as a guide and always cross-check the product listing before you buy. The table below covers every Australian bed size in cm.

Single & King Single

Single blankets are typically around 180 × 240 cm, and king single blankets are typically around 200 × 240 cm. These sizes give enough width to cover a single or king single mattress with side drop on both sides and a foot overhang that can be tucked under or left loose. Because king single mattresses are 15 cm longer than a single, the extra blanket length matters more than the width difference; both single and king single blankets often share the same 240 cm length.

If the bed is against a wall on one side, a smaller blanket size can work because you only need overhang on one side and the foot. Kids' rooms and guest rooms usually use single-size blankets, and king single is a common upgrade for teenagers or taller sleepers who want extra room without going up to a double.

Double & Queen

Double blankets are typically around 220 × 240 cm, and queen blankets are typically around 240 × 260 cm. The queen blanket is roughly 20 cm wider than the double, which matches the 16 cm mattress width difference (double 137 cm vs queen 153 cm) plus a bit of extra drop. Queen blankets are also often 20 cm longer than doubles because a queen mattress is 15 cm longer.

Queen is the most commonly sold blanket size in Australia because queen is the most common bedroom mattress size. If you sleep with a partner, upsize toward the queen range or larger to avoid the classic mid-sleep blanket tug-of-war; two adults sharing a double blanket typically end up with one person underslept and cold by 3am.

King

King blankets are typically around 270 × 270 cm. This is a genuinely larger blanket than a queen, not just a slight upsize: king mattresses are 30 cm wider than queen (183 vs 153 cm), so a king blanket needs to be about 30 cm wider too. Length is similar to queen because king mattresses are the same 203 cm long as queens.

Super king mattresses (203 × 203 cm) sit above king in the AU size chart and take blankets around 285 × 285 cm. These are less commonly stocked at Australian retailers, so buyers with super king beds often need to search specifically for "super king" blankets rather than picking one up in-store.

Blanket Sizes vs Doona & Quilt Sizes

Blankets and doonas (also called quilts or duvets) are sized differently, and mixing them up is one of the most common bedding-purchase mistakes. Blankets tend to be wider and shorter, designed to drape down both sides of the mattress and get tucked under at the foot. Doonas and quilts tend to be narrower and closer to the mattress footprint, sized to sit on top of the mattress with just enough overhang to tuck around a partner. A queen blanket is around 240 × 260 cm, while a queen doona is typically around 210 × 210 cm.

Why the difference? Blankets are single-layer coverings meant to sit inside a made bed with sheets tucked under. Doonas are stuffed with down, down-alternative or wool fill and encased in a cover, so they need less overhang because the loft (thickness) adds warmth that a blanket relies on width for. Our Koala Duvet 2nd Gen, All Seasons Duvet and Balmy Night Duvet all follow the standard AU doona sizing convention, so the doona sits on the mattress rather than draping to the floor.

If you're building a full bedding set, a common layered approach is: fitted sheet, flat sheet, blanket (or throw), and doona on top. Each layer follows a slightly different size logic, which is why bedding sold as "queen" from one brand can look different in coverage to "queen" from another.

How to Choose the Right Blanket Size for Your Bed

Choose your blanket size to match your mattress dimensions rather than your bed frame, because blankets are sized for the mattress and any bed-frame overhang is decorative. Add roughly 40 to 60 cm to your mattress width and 30 to 50 cm to your mattress length to work out the minimum blanket size you need. Then consider three factors:

Who you sleep with. If you sleep with a partner, upsize by one category so both people get equal blanket coverage. Two adults sharing a queen blanket generally works; two adults sharing a double blanket doesn't. If you both prefer different warmth levels, some couples use two smaller blankets side-by-side instead of one shared larger blanket.

How you sleep. Restless sleepers who move a lot benefit from a larger blanket that stays put through the night, while still sleepers can get away with a blanket sized closer to the mattress. If you tuck your blanket under the mattress at the foot, add another 15 to 20 cm to the length so there's enough to tuck without pulling the top edge down.

Your bed height. A tall bed base (especially a pocket spring or platform base) sits higher off the floor, so a blanket that drapes further down the side looks more balanced. Low-profile beds work with smaller blanket sizes because there's less side to cover.

Once you've settled on a size, also think about the season: a lightweight cotton or linen blanket layers under a doona in winter, while a wool blanket alone can be enough for spring and autumn nights. Our homewares range covers throws, cushions and other bedding accessories that layer with the duvet range to build a full setup.
