If your King quilt leaves less coverage than you like, Super King adds fabric at the sides and foot. Compare the measurements to see whether that fuller finish suits your bed and the way you sleep.

01 / Separate the sizes

Your mattress and quilt measure differently

A quilt needs room to sit over sleepers and drape beyond the mattress. Its measurements are therefore different from the bed size printed on the label.

Australian reference sizes — width × length
Item Dimensions
King mattress, approximately 183 × 203 cm
King quilt 245 × 210 cm
Super King quilt 270 × 240 cm

270 × 240 cm describes the quilt, not a Super King mattress. Check the actual dimensions on both insert and cover, as brand sizing can vary.

02 / Picture the difference

More width, plus extra length

Both diagrams use the same scale and the same 183 × 203 cm King mattress. Head edges are aligned; the quilt is shaded and the mattress has a dashed outline.

King quilt

245 × 210 cm

Head edge

31 cm nominal width per side

(245 − 183) ÷ 2 = 31 cm

Super King quilt

270 × 240 cm

Head edge

43.5 cm nominal width per side

(270 − 183) ÷ 2 = 43.5 cm

The gain is 12.5 cm per side, plus 30 cm at the foot when the head edges are aligned. These flat allowances are not guaranteed hanging depths. Sleepers, filling loft, mattress height and where you place the quilt affect the finished drape.

When does upsizing make sense?

Choose a fuller finish

Compare Super King if your King quilt looks narrow, you want more fabric to share or you prefer a longer fall at the foot. Measure the bed-frame height so the extra fabric sits comfortably above the floor.

Keep a neater drape

A King quilt may already give the coverage you like. On a lower bed, a longer quilt can create more overhang than you want. Use your current quilt as a useful starting point.

Three checks before you change sizes

  1. Measure the bed

    Record mattress width, length and total depth, including the topper.

  2. Compare your quilt

    Measure it flat and note where you want more coverage: sides, foot or both.

  3. Check the label

    Confirm insert and cover dimensions, then compare filling, weight and care requirements.

Upsize the quilt. Fit sheets to the mattress.

Quilt cover
A Super King insert needs a Super King quilt cover with matching dimensions. An oversized cover alone will not add filled coverage.
Fitted sheets
A King mattress still needs King sheets. For a deeper mattress, compare King Extra Depth sheet sets and check the wall measurement.
Super King mattress
A true Super King mattress is approximately 204 × 204 cm and needs sheets for that wider footprint. It is a different purchase from a Super King quilt.

A few common questions

Can I put a Super King quilt on a King bed?

Yes. Compare the quilt's 270 × 240 cm dimensions with your bed and preferred drape. Choose the cover to match the insert.

Will Super King cover a deep King mattress?

It provides more fabric than King, but coverage depends on your mattress depth, topper, sleepers and quilt loft. Measure the drop you want before choosing.

Does a larger quilt make the bed warmer?

It adds coverage, but warmth also depends on filling, construction and weight. Choose those details for your room temperature and personal preference.
