What size is a super king bed in NZ?

The standard New Zealand super king mattress measures 203 cm by 203 cm — that’s 80 inches square, making it the largest standard bed size you can buy here. A queen, by contrast, is 153 cm wide and 203 cm long, and a king sits at 167 cm wide. The The Foxes Den (specialist bedding guide) lays it out clearly: the Australian king is the same size as the NZ super king, so if you’re mixing markets, watch carefully.

Is a queen size bed the same as a super king?

No — a queen is 153 cm wide and 203 cm long, a full 50 cm narrower than a super king. The Linen House NZ (bedding sizing specialist) confirms seven distinct mattress sizes in New Zealand, and queen is the third smallest.

What is the biggest bed you can buy in NZ?

The super king is the widest and longest standard mattress available. Some retailers also offer custom-built oversized beds, but for off-the-shelf sheets, the super king is the ceiling.

Bottom line: The super king is 203 cm square — a full 36 cm wider than a king. If you’re shopping online, check the centimetre numbers, not the label name.

Which is bigger, super king or king size bed?

The super king is 203 cm wide; the king is 167 cm wide. Both are 203 cm long. That 36 cm difference — roughly the width of a standard pillow — is what makes the distinction matter for sheet buying.

Two beds, one length, but a full 36 cm of extra width on the super king.
Dimension Super king King Queen
Width 203 cm 167 cm 153 cm
Length 203 cm 203 cm 203 cm
Surface area per person (shared bed) ~10,300 cm² ~8,500 cm² ~7,800 cm²

The Consumer NZ (independent testing authority) advises measuring your mattress before buying — depth can vary, and a sheet that fits one 25 cm deep mattress might not fit another.

The trade-off

Sharing a super king gives each person roughly 20% more lateral space than a king. For couples who move in their sleep, that extra width matters.

Bottom line: The super king is 36 cm wider than a king, both are 203 cm long. If you want the largest standard sheet you can buy in NZ, that’s it.

Can king sheets fit super king?

Officially, no — a king fitted sheet is designed for a 167 cm wide mattress and will not properly cover a 203 cm wide super king. However, some New Zealand shoppers have found a workaround.

Should I buy super king sheets for a king bed?

A super king sheet on a king bed will leave excess material that can bunch up or slip, and the elastic may not grip properly. The Foxes Den (specialist bedding guide) recommends measuring your mattress depth — if it’s over 40 cm, you need deep pocket or extra deep sheets.

Kmart king sheets as a stretch fit

On Reddit, users have reported that Kmart’s king-size fitted sheets — which retail around $25 — can stretch to fit a super king due to the elastic and fabric give. This is not an official fit, and results may vary over time. For a reliable fit, dedicated super king sheets are the safer bet.

What to watch

If you try the Kmart workaround, check after a few washes — the elastic can fatigue. A proper super king sheet with deep pockets will last longer.

Bottom line: King sheets are 36 cm too narrow. The Kmart hack might save you $15, but it’s a temporary fix, not a permanent solution.

What are the best sheets to buy in NZ?

The best sheet depends on your budget and your preference for feel. Consumer NZ (independent testing authority) says natural fibres breathe better — cotton is the obvious choice for breathability — and thread counts in their reviewed market ranged from 180 to 1000.

What bed sheets do 5 star hotels use?

Luxury hotels typically use high thread count cotton sateen or percale in the 300 to 600 range. Linen House NZ (bedding sizing specialist) notes that all NZ pillowcase sizing is based on standard Linen House sizing — other manufacturers may differ.

What is the best bed brand in NZ?

Popular NZ retailers for super king sheets include Bed Bath N’ Table (premium), Briscoes (frequent sales), The Warehouse (budget), and Kmart (cheapest). Harvey Norman NZ (retailer) advises checking for wear signs like holes, tears, discolouring, and thinning to decide when to replace.

Four retailers, four price points — and a choice between cotton and synthetic.
Retailer Price range (super king fitted) Material Thread count
Kmart $25–$40 Microfiber / cotton Not published
The Warehouse $25–$50 Cotton percale 200
Briscoes $40–$80 Cotton sateen 300–400
Bed Bath N’ Table $50–$150 Egyptian cotton / sateen 300–600
The upshot

If you want crisp, cool sheets, go for cotton percale at 200–400 thread count. If you want a soft, smooth feel, cotton sateen at 300–600 is the luxury hotel standard.

Bottom line: Kmart and The Warehouse are the budget picks; Bed Bath N’ Table and Briscoes are the premium options. For a super king, expect to pay $40–$150 for good quality.

Does Kmart do super king sheets?

Yes — Kmart New Zealand sells super king fitted sheets, typically in basic solid colours for around $25 to $40. Their selection is limited compared to larger retailers, but the price is among the lowest in the country.

What about The Warehouse?

The Warehouse also stocks budget super king fitted sheets, starting at around $25. Both retailers offer value for money, but thread counts are not consistently published.

Community reports on Reddit suggest that Kmart’s king-size fitted sheets might be used as a cheap alternative for super king beds, but this is not a guaranteed fit.

“I once heard that Kmart’s king size fits a super king? Has anyone tried it?”

— Reddit user on r/newzealand

“Never assume international bedding sizes are interchangeable — always check the centimetre measurements.”

— The Foxes Den (specialist bedding guide)

“Natural fibres breathe better, and cotton is the obvious choice for breathability.”

— Consumer NZ (independent testing authority)

“All New Zealand pillowcase sizing is based on standard Linen House sizing — other manufacturers may differ.”

— Linen House NZ (bedding sizing specialist)

For New Zealanders shopping for super king sheets, the choice is clear: if you want a reliable fit, buy dedicated super king sheets from a retailer that publishes centimetre dimensions. If you’re on a tight budget, the Kmart king sheet hack may work as a short-term fix, but expect the elastic to wear out faster. The safest approach is to measure your mattress and buy sheets that match those exact numbers.

Frequently asked questions

What thread count is best for super king sheets?

For cotton sheets, 300 to 600 thread count is the sweet spot — 300 for percale (crisp), 600 for sateen (smooth). Consumer NZ says to check both thread count and ply.

Are super king and California king the same size?

No — a California king is 203 cm long but only 183 cm wide. The NZ super king is 203 cm square. They are not interchangeable.

Which store has the best super king sheet sales in NZ?

Briscoes runs frequent bedding sales, often 40–50% off. Bed Bath N’ Table has premium sales a few times a year.

How do I wash super king bed sheets?

Check the care label — most cotton sheets can be washed on a warm cycle and tumble dried on low. Avoid fabric softeners, which can reduce breathability.

Can I use queen sheets on a super king bed?

No — a queen sheet is 153 cm wide, 50 cm narrower than a super king. It will not fit.

Do I need deep pocket sheets for a super king mattress?

If your mattress is over 40 cm deep, yes. Look for “deep pocket” or “extra deep” on the label.

What is the return policy for super king sheets at Bed Bath N’ Table?

Bed Bath N’ Table offers a 30-day return policy on unused, unwashed sheets. Check their website for full terms.
