When it comes to choosing the right bedding, a clear, reliable reference is priceless. In New Zealand, a standard king size mattress measures 167 cm × 203 cm, and getting this footprint right is crucial for a snug fit of sheets, protectors and bed frames.
Loose corners and constant tugging often stem from mismatched dimensions—especially with imported sets. A quick look at the market shows why precision pays off: the NZ mattresses market (B2C mattress revenues) is projected to reach US$80.8 million in 2025, with US$21.4 million tied to bed-specific revenues.

King Size Mattress Dimensions Importance
In New Zealand, a standard king size mattress runs 167 cm wide by 203 cm long—a footprint that differs significantly from US and UK variants. Accurate measurements influence everything from base and headboard choices to the clearance around your bed.
Key considerations:
- Comparing NZ, US and UK king size footprints
- Planning for a typical 12′ × 12′ (3.7 m × 3.7 m) room
- Selecting fitted sheets that hug corners without slipping
For instance, a US king sheet set stretched over an NZ king mattress will leave excess fabric at the edges, causing unsightly folds and discomfort.

- Returns and exchanges due to simple measurement errors
Use this quick reference to set the basics before diving into tolerances, depths and frame styles.
NZ Mattress Size Reference
Here’s a consolidated view of essential New Zealand mattress dimensions used by local retailers and manufacturers. Referencing these figures ensures you pick the right sheets, protectors and bed frames the first time.
NZ Standard Mattress Size Chart
| Size Name | Width (cm) | Length (cm) | Typical Depth (cm) |
|---|---|---|---|
| Single | 92 | 188 | 18–22 |
| Double | 137 | 188 | 18–24 |
| King | 167 | 203 | 20–28 |
| Queen | 152 | 203 | 18–28 |
| Super King | 183 | 203 | 23–35 |
Use this chart to:
- Confirm frame build tolerances
- Match sheet pocket depths
- Choose correct protectors and bed skirts
How To Read Depth And Size
Depth varies by construction type—innerspring, foam or hybrid. Most brands allow ±2 cm stitching tolerance.
When you measure:
- Start at the floor and go up to the top quilting surface
- Check width and length mid-mattress to avoid side bulges
- Verify your fitted sheet’s pocket depth matches the mattress height
This simple check stops ill-fitting accessories and returns.
International King Size Comparison
An NZ King mattress (167 cm × 203 cm) differs from the North American King (193 cm × 203 cm). Local footprint nuances influence everything from sheet designs to frame dimensions. For global size charts, see The Foxes Den.

Dimensional Tolerances And Depth Guide
Manufacturers typically allow ±2 cm leeway on king-size mattress width and length, accommodating small production variances. Depth, however, directly affects sheet fit and frame clearance.
Even a 2 cm shift in width can yield up to 4 cm total difference corner-to-corner. Always confirm final measurements—especially before ordering custom bedding—to prevent gaps or movement.
Cross-reference mattress depth with your frame’s skirting height to avoid interference. Next, learn how to measure both mattress and frame accurately in NZ.
Depth Categories Explained
| Depth Category | Range | Typical Bedding |
|---|---|---|
| Standard | 18–22 cm | Fitted sheets for most standard mattresses |
| Mid-Range | 23–28 cm | Pillow-top and thicker foam models |
| Premium | 29–35 cm+ | Deep-pocket sheets or adjustable sliders |
A 30 cm premium mattress on a low-profile base often causes sheet bunching. Matching your sheet’s pocket depth to the mattress thickness ensures a smooth, wrinkle-free finish.
Visual Fit Examples
- A 22 cm mattress on a 20 cm pocket sheet leaves 2 cm slack per corner, increasing slippage.
- A 28 cm mattress with 30 cm deep-pocket covers fits snugly, keeping bedding taut.
- Use extenders sparingly, as they can alter fitted-sheet tension.
Measuring Mattress And Frame Process
Accurate measurements mean a snug bedding fit every time. Clear the mattress of sheets, protectors and cushions before you start to avoid false readings.
Essential tools:
- Metric tape measure (accurate to 0.5 cm)
- Straightedge for height and depth checks
- Notebook or measuring app for immediate logging
- Assistant to hold the tape on larger mattresses
Measurement steps:
- Check width at head, centre and foot—record the largest.
- Measure length at left, centre and right—note the maximum.
- For height, run tape from floor to top quilting, ensuring it’s flush against the side.
- Measure the inner span between rails or slats to confirm frame fit.
Handling Adjustable Bases And Storage Beds
Adjustable bases should be measured flat so fitted sheets slot neatly. Storage beds require an inside compartment angle check—measure for lid clearance and avoid pinch points.
Pro Tip Double-check every measurement and allow a ±2 cm tolerance before placing your order.
| Measurement | Where to Measure | Why It Matters |
|---|---|---|
| Width | Head, Centre, Foot | Avoid bulges |
| Length | Left, Centre, Right | Fit bedding length |
| Height | Floor to top quilting | Match sheet pockets |

Also confirm doorways, hallways and tight corners to ensure both mattress and frame clear every passage.
Bedding And Sheet Compatibility Guide
Matching sheets, protectors and bed skirts to your king size measurements mattress in NZ becomes seamless with precise dimensions.
Key NZ Sheet Dimensions
- Fitted sheet pocket depth: 25–30 cm for a 167 × 203 cm mattress
- Flat sheet size: 300 × 310 cm to allow generous tucking
- Protector & bed skirt widths: 170–180 cm for full edge coverage
Adapting Imported Sheets
Imported fitted sheets often fall short of NZ pocket depths. Simple adjustments can save you from reordering:
- Measure pocket depth at corners and centre to note variations
- Attach elastic extenders along sides for extra stretch
- Test the fit and trim any surplus fabric for neat corners
Tip Ensure pockets exceed mattress depth by at least 5 cm to prevent slippage.
Secure oversized protectors with corner stays or silicone grips. Learn about eco-friendly deep-pocket options in our guide on Bamboo Sheets New Zealand.
Local brands like Bedding Inn and Quilt Matters design sheet sets specifically for the 167 × 203 cm king mattress, ensuring a perfect fit every time.
