NZ bedding sizes – what you need to know

When you shop for sheets, blankets or a new mattress in New Zealand, the size labels can feel confusing. You might see ‘double’, ‘king’ or numbers like 120cm. This guide cuts through the jargon so you can pick the right fit without guessing.

First, measure your mattress. Use a tape measure for the width (side to side) and length (head to foot). Most NZ beds follow standard dimensions, but a few boutique sizes slip through the cracks. Write down the numbers – they’ll be the anchor for everything else.

Standard bed sizes in New Zealand

Here’s the most common list. All measurements are in centimeters (cm) and refer to the mattress surface.

• Single (Twin) – 92 × 188
• Extended Single – 92 × 203
• Double (Full) – 138 × 188
• King – 152 × 203
• Queen – 152 × 188
• Super King – 180 × 200

If your mattress is a non‑standard size, check the label or ask the retailer for the exact numbers. The extra few centimeters can make a big difference when you buy fitted sheets.

How to pick the right bedding

Once you know your mattress dimensions, match them to the bedding label. Look for these words on sheet packs:

• Fitted – the sheet that wraps around the mattress. It should list “fits 92 × 188” or similar.
• Flat – the top sheet. This one is more forgiving, but a size that’s too small will look uneven.
• Cover – duvet or blanket covers. Choose a cover a few centimeters larger than your duvet for a tidy drop.

Don’t forget the depth of your mattress. Some modern mattresses have extra padding or a pillow top that adds 5‑10 cm. If the depth is higher than the fitted sheet’s pocket, the sheet will pop off. Look for “deep pocket” or “extra deep” options.

Another tip: buy a set that includes pillowcases sized for your pillows. NZ pillow sizes usually follow the same naming as the bed (single, queen etc.), but the actual measurements are often 40 × 50 cm for single and 50 × 75 cm for queen‑size. Check the tag if you’re unsure.

When you’re picking blankets or duvets, think about how much you want them to drape over the sides. A duvet that’s 10 cm wider than the mattress on each side gives a relaxed look. If you’re aiming for a sleek, hotel‑style finish, choose a duvet that matches the mattress width exactly.

Finally, read the care label. Some fabrics shrink after the first wash, which can affect the fit. Cotton tends to shrink a bit, while polyester stays the same. If you love a snug fit, pre‑wash cotton sheets before you use them.

Now you’ve got the basics: measure, match the label, watch the depth, and check care instructions. With these steps, you’ll never end up with a sheet that slides off the bed again.
