What size is a king single bed?
The king single bed size in New Zealand is a defined category that sits between a single and a double. Most retailers agree on the core dimensions, though minor variations exist.
King single dimensions in cm
- Width: 107 cm (Ecosa NZ mattress size guide)
- Length: 203 cm (same source)
- Area: 2.17 m²
King single dimensions in inches
- Width: 42.1 inches
- Length: 79.9 inches
Variations between NZ brands
Sealy NZ (official size guide) lists the king single at 1055 × 2030 mm — a 1.5 cm difference in width. Sleepyhead (Sleepyhead mattress size guide) and BedsRus (BedsRus size guide) both use 107 × 203 cm. The Foxes Den (single & king single guide) confirms the extra length over a single.
When buying a mattress, always measure your existing bed frame or check the retailer’s exact specs. A 1.5 cm discrepancy can cause a poor fit in a fitted sheet or bed frame.
The implication: the king single is a consistently longer option than a single, but width can vary by manufacturer. For most buyers, the 107 cm standard is safe; for others, double-checking with the specific brand is wise.
Is a king single the same as a double?
No — while the king single shares the double’s “king” label, it is narrower and longer. The difference in width is significant enough to affect sleeping comfort for two people.
Width and length differences
The comparison table below shows exactly where the king single wins on length but loses on width versus a double.
| Dimension | King single | Double |
|---|---|---|
| Width | 107 cm | 137 cm |
| Length | 203 cm | 188 cm |
| Area | 2.17 m² | 2.58 m² |
| Width per person (2 sleepers) | 53.5 cm | 68.5 cm |
- King single is 30 cm narrower (Ecosa comparison)
- King single is 15 cm longer (same source)
Who should choose each size
- King single: solo sleepers over 180 cm tall, teenagers, guest rooms with limited floor space
- Double: couples on a budget, shorter adults, spaces that can accommodate extra width
A tall person who chooses a double gets extra width but sacrifices 15 cm of legroom — a real concern for those over 185 cm. The king single solves legroom without the footprint of a double.
The trade-off: the king single is the better choice for a tall solo sleeper; the double is the minimum viable width for two people despite its shorter length.
Are two single beds the same size as one king?
Two single beds pushed together create a surface that is wider than a king, but with a gap in the middle and different total length.
Combined width of two singles
- Standard single width NZ: 91.5 cm (some retailers use 92 cm) (The Foxes Den)
- Two singles side by side: 183 cm
- NZ king width: 165 cm (Ecosa king size)
Practical considerations
- Two singles provide 18 cm more total width than a king
- Length of a standard single: 190 cm; king single: 203 cm — two singles are shorter than a king if using single, not king single
- Gap between mattresses is uncomfortable for couples
Using two king singles (107 cm each) creates a 214 cm wide bed — that’s 49 cm wider than a standard king. But few NZ bedrooms have space for that setup.
The pattern: two standard singles are wider than a king, but shorter. Two king singles are both wider and longer than a king — a luxury that requires lots of floor space.
Is 180×200 a king size bed?
180×200 cm is a common European or Asian king/queen size, but it is not the standard New Zealand king size.
NZ king bed standard
- New Zealand king: 165 × 203 cm (Sleepyhead, Ecosa)
- European king (often called queen in Europe): 160×200 cm to 180×200 cm
Understanding metric bed sizes
- 180×200 cm is 15 cm wider and 3 cm shorter than NZ king
- European retailers may label 180×200 cm as “queen” or “king” depending on market (TreasureBox NZ/AU comparison)
The implication: if you’re importing a mattress or bed frame from Europe, double-check the actual dimensions — 180×200 cm will not fit a standard NZ king bed base.
Can two people fit in a king single bed?
Technically yes, but comfort is compromised. The king single offers 107 cm of width, which splits to about 53.5 cm per person — less than a standard single per person.
Width per person
- Each sleeper gets 53.5 cm — a standard single is 91 cm, nearly double the space
- For reference, a double gives 68.5 cm per person
Alternatives for two people
- Double (137 cm): minimum viable for two adults
- Queen (153 cm): comfortable for two
- King (165 cm): generous for two
“A king single is designed as a larger single, not a smaller double. It works well for a solo tall sleeper but is not suitable for two adults.”
For occasional use with two children under 10, a king single might work. For adults, choose a double or larger — the width difference (30 cm extra) makes a real difference to sleep quality.
Why this matters: many shoppers see “king” in the name and assume it fits two people. It doesn’t — the king single is a single bed with extra length, not extra width for a partner.
Clarity: what we know and what remains unclear
Confirmed facts
- King single dimensions are 107×203 cm in NZ (common standard) (Ecosa)
- King single is longer than a standard single (203 vs 190 cm) (The Foxes Den)
- Double is 137 cm wide vs 107 cm for king single (Ecosa)
What’s unclear
- Exact tolerances between brands (107 cm vs 105.5 cm) (Sealy)
- Whether Australian king single dimensions match NZ exactly (TreasureBox)
- Some retailers list double at 138×188 cm, others at 137×190 cm — consistent length not universal (8hours)
- Two singles side by side exceed king width only if using standard single dimensions — the exact width depends on which retailer’s single spec is used
What experts say about king single sizing
“Our king single mattress is 1055 mm wide by 2030 mm long. We recommend measuring your bed base before purchase to ensure a proper fit.”
— Sealy NZ mattress size guide (official manufacturer)
“The king single is the go-to size for taller children and teenagers who have outgrown a single but don’t need a double. It fits standard single bed frames but offers extra length.”
“New Zealand and Australian mattress sizes are very similar, but there can be 1–2 cm differences. Always check the exact dimensions from the seller, especially for king single.”
— TreasureBox NZ vs AU mattress size guide (homeware retailer)
For tall New Zealanders shopping for a bed, the choice between a king single and a double comes down to one question: do you need legroom or width? The king single delivers an extra 15 cm of length over a double, but sacrifices 30 cm of width. For solo sleepers over 180 cm tall, the king single is the smarter buy – unless you plan on sharing your bed. For couples, the double or larger is the minimum acceptable standard.

Frequently asked questions
What are the standard bed sizes in New Zealand?
Standard NZ bed sizes include single (91×190 cm), king single (107×203 cm), double (137×188 cm), queen (153×203 cm), and king (165×203 cm). Dimensions can vary slightly by brand.
How wide is a king single bed?
The standard width is 107 cm. Some brands like Sealy list it at 105.5 cm, so always check the specific product dimensions.
What is the difference between a king single and a single XL?
A single XL (extra long) is typically 91×203 cm — same width as a single but same length as a king single. The king single is both wider and longer than a single XL. Single XL is less common in NZ.
Can a king single fit a tall person?
Yes. At 203 cm long, it comfortably accommodates sleepers up to about 195 cm tall. Taller individuals may still need a custom option.
Is a king single mattress the same in Australia and New Zealand?
Mostly yes — both markets use 107×203 cm as common standard. But some Australian retailers may use 106×203 cm; confirm with the seller before cross-border purchase.
What sheet size fits a king single bed?
Look for fitted sheets labelled “king single” with dimensions around 107×203 cm. Standard single sheets will be too short and too narrow. Brands like The Foxes Den and Ecosa offer dedicated king single bedding.
