Bed Frame Size Guide|Single / Double / Queen / King
- Mattress and bed frame sizes may vary slightly across brands. For the best fit, we recommend purchasing your bed frame and mattress from the same brand, or speak with customer service team for advice.
When choosing a bed frame in Hong Kong, it’s important to note that most brands use either feet (ft) or centimetres (cm)as their main unit of measurement. Bed frames are usually displayed in two dimensions:
Outer frame size – the total footprint of the frame, which affects room space. (Orange border)
Inner frame size – the mattress fitting size. (Blue border)

- Tips: Always measure at floor level and subtract skirting board depth.

Custom Bed Frame Sizes
Need a special size? Napnice offers made-to-order bed frames tailored to your space and mattress. Contact us today for free consultation and quotation!

A custom-made bed frame typically requires around 4 to 6 weeks from order confirmation to home delivery.
Once an order is confirmed, cancellations or refunds cannot be accepted.
All customised bed frames are still covered by our warranty service, ensuring reliable quality and peace of mind.
How to Choose the Right Bed Frame Size
Other that the room size, it is important to consider the below 4 factors for choosing a best fit bed frame:
- Sleeping Habits & Number of Users
Are you sleeping alone, as a couple, with a child, or even with pets?
If you often toss and turn, or prefer more personal space, choose a larger size.
If you’re taller than 180cm, we recommend an extended-length bed frame.
- Sleeping Habits & Number of Users
Measure your bedroom carefully and leave enough walking space.
- Tip: For smaller rooms, consider a headboard-free and/or edge-free design to save space (reduced outer edges).
3. Access & Moving Restrictions:
In some older buildings, narrow lifts, staircases, or tight corners may make it difficult to move in larger bed frames. We recommend confirming the packaged bed frame dimensions in advance.
4. Space for Installation
Most bed frames require assembly on site. Certain structures may need to be unfolded, rotated, or secured with screws. Please ensure there is sufficient space for installation before delivery.
- Tip: All Napnice bed frames are designed for hassle-free setup and do not require any additional installation space.
Matching Bed Frames with Mattresses
The mattress size must match the inner frame size to avoid slipping or instability.
For headboard-free or footboard-free designs, ensure the mattress does not extend too far.
Storage bed frames are usually higher, so match them with a suitable mattress thickness for comfortable access.
- Tips: Purchase both the mattress and bed frame together, or contact us to customise the right fit.
