Super King Bed Extra Depth - Fitted Sheets

<p>Super King fitted sheets are designed specifically for wider Australian beds, giving you a sheet that actually matches the mattress size (203 x 203 cm) instead of stretching a smaller one to fit. When the fitted sheet is cut to the correct dimensions and depth, it hugs the mattress properly, the corners stay tucked, and the whole bed looks smoother and more premium. This is especially important for super king mattresses with toppers or pillow-top finishes, because they sit higher and standard fitted sheets can pop off or leave the sides exposed. Choosing a true Super King fitted sheet made for 203 x 203 cm beds means less wrestling on wash day and a neater, hotel-style base to layer your quilt cover and pillows on.</p>

 

FREQUENTLY ASKED QUESTIONS

What size is a super king fitted sheet in Australia?

An Australian super king mattress measures 203 × 203 cm, a near-square bed that is 20 cm wider than a standard king (183 × 203 cm) but the same length. Super king fitted sheets are sized to suit that footprint, typically with 30–40 cm wall depth for standard mattresses and 40–50 cm for deeper ones. For exact measurements of every Australian bed size, our bed linen sizing guide has the full breakdown.

What's the difference between a king and a super king bed?

A standard king mattress measures 183 × 203 cm, while an Australian super king is 203 × 203 cm, 20 cm wider and the same length, making it an almost perfectly square bed. That extra width adds meaningful space for couples. It also means king and super king fitted sheets aren't interchangeable. For a full comparison of Australian bed sizes and their sheet requirements, our bed sheet sizes guide covers every size.

Is the Australian super king the same size as a UK super king?

No, they're very different. A UK super king measures 180 × 200 cm, while an Australian super king is 203 × 203 cm. The Australian size is 23 cm wider and 3 cm longer. UK super king fitted sheets will be too narrow and too short for an Australian super king mattress. If you're purchasing sheets from an international retailer, always confirm whether the sizing is Australian or UK before ordering.

Will a king fitted sheet fit a super king mattress?

No, a king fitted sheet sized for 183 × 203 cm will be 20 cm too narrow for a super king mattress (203 × 203 cm). It will pull away from the corners overnight and wear out faster under the strain. The two sizes need their own specific sheets. For related guidance on sizing up for a larger bed, our guide to super king quilts on king mattresses is worth a read.

What does "extra deep" mean for a super king fitted sheet?

The depth or wall of a fitted sheet is the height of fabric that wraps down and underneath the mattress. Standard super king sheets have a 30–35 cm wall. Extra deep options go to 40–50 cm, needed when your mattress is taller than average due to a pillow top or a mattress topper stacked on top. Getting the depth right stops the sheet popping off the corners. Our guide to fitted sheets explains how to measure.

What materials are super king fitted sheets available in?

Super king fitted sheets come in cotton percale, jersey-knit, cotton-sateen, bamboo-linen, and satin. Cotton percale at 400TC is the most widely available and practical for everyday use: breathable, durable, and easy to launder. Jersey-knit stretches well over the corners of a larger mattress, which is particularly useful given the super king's extra width. For a practical comparison of how different materials perform in Australian conditions, our bed sheet materials guide covers the details.
