How to use the Nightstand Height Calculator
- Choose Units: inches or centimeters.
- Pick a “Type of bed”: platform bed, bed with box spring, low platform bed or raised adjustable base. Each gives a rough mattress top range. The default is the box spring bed.
- Or choose “I measured my mattress” and type the “Mattress top height from the floor”. Measure from the floor to the top of the mattress with the sheets on and any topper in place. Zero and non-numeric entries return an error.
- Check for a warning. A custom height outside 8–48 in triggers a warning, so confirm the number you typed.
- Read the “Nightstand top” result for each guide. Guide A, Guide B, and Guide C each show their own range. Compare all three rather than picking one. For a bed type, the tool also shows the nightstand height guide C lists for that bed, and the most common nightstand height (24–26 in in guides B and C).
- Note the allowance behind each range. Guide A allows the top up to 2 in above the mattress, while Guides B and C allow up to 4 in above it.
You can switch between a bed type and a typed height to compare results. A bed type gives a range for that bed in general, while a typed height gives results for your exact mattress.
How tall should a nightstand be next to a bed?
The nightstand top is set relative to the mattress top, and each guide allows it to sit a set distance above that point. The lowest nightstand top equals the mattress top height, and the highest equals the mattress top plus the allowed height above it.
For a box spring bed with a mattress top at 24–28 in, Guide A gives 24–30 in, while Guides B and C give 24–32 in. Guide A allows 2 in above the mattress, and Guides B and C allow 4 in. Guide C adds that the top should be no more than 5 in above the mattress.
Take a platform bed with a mattress top of 20–24 in. Guide A gives 20–26 in, and Guides B and C give 20–28 in. A custom mattress top of 26 in gives Guide A 26–28 in and Guide B 26–30 in. Guide C also lists a recommended nightstand height for each bed type, such as 24–28 in for a box spring bed. These recommendations are separate from the calculated ranges.
Why do the nightstand height guides give different answers?
The guides are retail and furniture-blog sources, not a standard, so nightstand heights follow a rule of thumb. Nothing is averaged here, because the guides disagree on how far above the mattress the top may be. Each rule is shown for its own guide so you can see where they differ.
The sources also disagree in small ways. Guide C’s table gives a platform bed mattress top of 20–24 in, but its text says platform beds are often 14–20 in. The bed type ranges are rough for this reason, and measuring your own mattress is the more reliable input.
Typical nightstand sizes differ by guide. Guide A lists 24–28 in tall, or 30–34 in for chest styles. Guide B lists 22–28 in tall, with 24–26 in most common, 18–24 in wide, and 16–20 in deep. Guide C lists 23–28 in tall, with 24–26 in most common, 21–28 in wide, and 15–20 in deep.

Frequently asked questions
Is the nightstand height measured from the floor or from the bed frame?
The tool works from the mattress top height, so measure from the floor to the top surface of the mattress. The nightstand top range is then compared against that number.
What if I do not know my bed type?
Measure the mattress top and type the number in. Bed type ranges are rough, and the guides themselves note that platform bed heights vary.
Can I enter centimeters instead of inches?
Yes. The tool accepts your mattress top height in inches or centimeters.
Why does the tool show three results?
The guides do not agree on how far the nightstand top can sit above the mattress: guide A allows up to 2 in, guides B and C up to 4 in. Showing all three lets you see the spread instead of a single averaged number.
Is a result a rule I have to follow?
No. The results are calculated from your inputs and the rules in the named sources. The sources are not a standard, so treat the numbers as a starting point.
What do the warning and the error mean?
A warning appears when a custom mattress height falls outside 8–48 in. An error appears when the height is zero or not a number, so enter a valid measurement to get results.
