Fitted Sheet Size Guide
Our sheets fit where others don’t.
If you’ve ever struggled to find fitted sheets that actually fit—you’re not alone. Traditional sheets are rigid and unforgiving, especially on mattresses that are deeper, thinner, or just a little out of the “standard” range.
At It-Fits®, we’ve designed something different. Our fitted sheets are made from 100% Australian cotton jersey—a naturally stretchy, breathable fabric that hugs your mattress like your favourite tee. With a deep wall that’s equivalent to a 50 cm woven sheet, and a 360° elastic hem, our sheets flex and stretch to fit snugly — even if your mattress is up to 8 cm longer, shorter, wider or narrower than standard Australian sizes.
Whether you’re making an adjustable bed, a caravan bunk, or your classic queen, our sizing system is designed to be easy, forgiving, and ultra-comfy.
Here’s what each size fits — and how our stretch makes it easier.
Single/long single
Fits mattresses: 92 cm wide x 183–203 cm long
Best for: Kids’ beds, solo sleepers, adjustable electric beds
Why it fits: Covers both standard and long lengths in one easy choice. Great for electric beds — our sheets flex with movement and stay smooth through the night.
King single
Fits mattresses: 107 cm wide x 203 cm long
Best for: Growing teens, taller solo sleepers, guest rooms
Why it fits: Our soft, flexible jersey stretches smoothly over this popular size—no bunching, no pulling.
Hot tip: Two King Singles are also a great fit for split California King beds, giving each sleeper independent comfort.

Fits mattresses: 138 cm wide x 183–203 cm long
