Fitted Sheet Sizes in Australia: Why "Standard" Doesn't Always Fit

Most people land here wanting a simple answer: what size sheet fits my bed. It seems like it should be a five-second question. In practice, it's a little more complicated than the label on your mattress suggests.

Australian mattress sizes aren't as standard as they look

A "queen" from one manufacturer isn't guaranteed to match a "queen" from another. Width and length usually stay close to the standard, but depth is where things really drift, some mattresses run a few centimetres deeper or shallower than the category suggests, especially once you add a topper. The size name on the tag is a guide, not a guarantee.

Why that small gap causes a big problem

With a standard woven sheet, there's no forgiving that gap. A few centimetres off and the sheet either won't stretch over the corners or sits loose enough to pull free overnight. That's exactly where the guessing starts, questions like whether a queen sheet will fit a king single, or whether sizing up is the safer bet. You shouldn't have to ask yourself that. If you're doing the mental maths on whether a sheet built for a different size might sort of work, the sizing system has let you down, not you.

Why It-Fits sheets don't have that problem

Cotton jersey is knitted, not woven, so it stretches. Combine that with the 8cm of flex built into every It-Fits fitted sheet beyond standard Australian dimensions, longer, shorter, wider or narrower, and the small inconsistencies between mattress brands stop being a problem you have to solve yourself. The sheet does the adapting instead of you.

It gets even trickier if your bed isn't a standard shape at all, caravan bunks and custom builds rarely match any size chart. That's exactly the kind of setup the caravan sheets collection is built for.

The easy way to find your size

We built two ways to skip the guesswork. If you'd rather just get a straight answer, the sizing guide quiz asks a few quick questions and tells you the right size. If you'd rather see the exact numbers yourself, the fitted sheet size guide has the full chart, and the sizing guide hub covers flat sheets, doona covers and pillowcases too, if you're sorting the whole bed at once.

Once you know your size, the fitted sheets collection has every option ready to go, made from soft, stretchy cotton jersey that stays in place once it's on.

"These sheets are hands down the best sheets I have ever bought!!" says Shirley B. "They are lovely and soft and stay on really well. The only sheets I have found so far," adds Anna M. More on the reviews page.
