How to read the charts
The publishers agree on the size names and differ by small amounts in the numbers: up to 1.5 cm in width and up to 3 cm in length. Both manufacturers add that a finished mattress may deviate from the guide, by 1 to 2 cm according to SleepMaker and by 15 mm according to Sealy.
Treat each size as a range. An Australian single is 91.5 to 92 cm wide and 187 to 190 cm long, depending on who states it.
King and super king: the two countries differ
- Australian king: about 183 × 203 cm.
- New Zealand king: 167 × 203 cm or 168.5 × 203 cm.
- New Zealand super king: about 183 × 203 cm, the size of an Australian king.
- Australian super king and New Zealand California king: 203 × 203 cm.
If you move between the two countries or order bedding across the Tasman Sea, compare centimetres.
Worked example: sheets from New Zealand
You have an Australian king mattress, 183 × 203 cm, and order king sheets from a New Zealand shop. A New Zealand king is about 167 cm wide, so the fitted sheet would be about 16 cm too narrow. The size to order is the New Zealand super king.
Common mistakes
- Assuming Australian and New Zealand sizes are identical. From king upwards they are not.
- Assuming an Australian queen is a US Queen. They are close, 153 × 203 cm and 152.4 × 203.2 cm, but frames and bedding are made to local sizes.
- Confusing king single and long single. A king single is about 106 cm wide; a long single is 92 cm wide. Both are 203 cm long.
- Expecting the mattress to match the guide to the millimetre.
