How Australian bed sizes compare
Australian sizes step up in width: a king single is 15 cm wider and 15 cm longer than a single, a queen is 15 cm wider and 15 cm longer than a double, and a king is 30 cm wider than a queen. Super king keeps the king length and adds another 20 cm of width to make a square 203 x 203 cm bed. Australian sizes are not the same as US or UK sizes (a US queen is a different width and length), so when you buy bedding online always compare the dimensions in centimetres.
Using mattress size to buy bedding
Quilts are much wider than the mattress so they hang over the sides; protectors, toppers and fitted sheets are cut to the mattress size so they sit flat. That is why a queen bed takes a 210 x 210 cm queen quilt but a 152 x 203 cm queen mattress protector. Measure the depth of your mattress too: pillow-top mattresses over 40 cm deep may need a quilt one size up for the same overhang.
