A nightstand that sits too low leaves you reaching down for your glasses or your phone every morning, and one that towers over the mattress blocks the view across the bed and looks out of place beside it. I size every nightstand off the top of the mattress, not off the floor alone, so the surface lands exactly where your hand expects it to be. Here is how tall a nightstand should be, how to measure your own bed for it, how far to place it from the mattress, and what width and depth actually fit your space.
Already know what you're shopping for? Here are the nightstands sized for platform beds, standard frames, and taller pillow-top mattresses.
How tall should a nightstand be?
Match the top of the nightstand to the top of your mattress, give or take about 1 to 4 inches. That range keeps the surface within easy reach from a lying or seated position, for setting down a glass of water or reaching for an alarm in the dark. It also keeps the piece from disappearing below the bedding or looming over the pillow.
| Bed and mattress type | Mattress top height | Nightstand height |
|---|---|---|
| Low platform bed | 18 to 24 in | Under 23 in |
| Standard bed with box spring | 24 to 25 in | 24 to 28 in |
| Bed with a thick mattress or pillow-top | 28 to 30 in | 28 to 30 in |
Most standard nightstands fall in the 24 to 28 inch range, which is why that height pairs with the majority of beds sold today. A platform bed with a slim mattress calls for something shorter so the top doesn't sit above the sleeping surface. A bed with a box spring and a thick pillow-top mattress needs a taller piece to keep that same level relationship.
How do I measure my bed for the right nightstand height?
Measure straight up from the floor to the top of your mattress, not to the top of the bed frame or headboard. That single number is what you match the nightstand against, since the mattress top, not the frame, is the surface your hand reaches from at night.
Once you have that measurement, look for a nightstand within about 3 inches of it in either direction. If your mattress top measures 26 inches, a nightstand anywhere from 23 to 29 inches will read as level and function well. Anything further outside that range starts to feel mismatched, either sitting noticeably below the bedding or rising above the pillow line.
Ready to match a nightstand to that number? Browse nightstands in the low, standard, and tall height ranges, in solid wood, metal, and mixed-material finishes.
How far should the nightstand sit from the bed?
Leave 3 to 6 inches between the nightstand and the edge of the bed frame or mattress. That gap is close enough to reach a phone or a glass without stretching, while still leaving room for the bedding to hang without bunching against the furniture.
Once that gap opens past about 8 to 10 inches, the nightstand starts to feel functionally out of reach, especially from a lying position, no matter how well its height matches the mattress. If your room forces a wider gap because of a radiator, vent, or outlet placement, a nightstand with a larger top surface helps compensate, since you can set items closer to the near edge.

What size nightstand fits my bedroom?
Width and depth matter as much as height once the piece is actually sitting beside your bed. A typical nightstand runs 18 to 28 inches wide, with narrower 12 to 17 inch pieces working well for twin beds or tight spaces, and wider 25-inch-plus pieces suiting king-size setups where the bed itself takes up more visual weight.
Depth usually falls between 16 and 24 inches. That's enough surface for a lamp, a book, and a glass of water without the nightstand jutting so far into the room that it narrows the walkway beside the bed. Before ordering, measure the clear floor space beside your bed frame and make sure at least 24 to 30 inches remains open for walking once the nightstand is in place.
What mistakes make a nightstand look or function wrong?
The same handful of mistakes show up on almost every nightstand pairing I get asked to fix.
- A nightstand sized off the bed frame or headboard height instead of the mattress top, leaving the surface too high or too low relative to where your hand actually reaches.
- A nightstand pushed flush against the bed with no clearance, or left so far away it stops being usable from a lying position.
- A deep nightstand chosen without checking the remaining walkway space, narrowing the path beside the bed.
- Mismatched nightstand heights on either side of the bed, breaking the visual balance even when each one works fine on its own.
- A nightstand top so narrow it can't hold a lamp and a book at the same time without crowding.
Building your nightstand plan step by step
Plan a nightstand in this order: measure the mattress top, set the height off that number, then confirm clearance and surface size last.
- Measure from the floor to the top of your mattress, not the bed frame or headboard.
- Choose a nightstand within about 3 inches of that height, using the low, standard, or tall ranges above as a starting point.
- Confirm 3 to 6 inches of clearance between the nightstand and the edge of the bed.
- Check that at least 24 to 30 inches of walkway remains open beside the bed once the nightstand is in place.
- Match the width to your bed size, narrower for a twin, wider for a king.
- Set your lamp on top and confirm the shade sits at a comfortable height before finalizing the pairing.

Frequently asked questions
How tall should a nightstand be? Level with the top of your mattress, give or take about 1 to 4 inches. Most standard beds pair with a 24 to 28 inch nightstand.
How far should a nightstand sit from the bed? 3 to 6 inches from the edge of the bed frame or mattress, close enough to reach comfortably without crowding the bedding.
What width nightstand fits a queen or king bed? 18 to 28 inches wide for most beds, with wider 25-inch-plus pieces suiting king-size setups where the bed takes up more visual weight.
Do both nightstands need to be the same height? Matching heights on either side of the bed keep the room visually balanced, even if the pieces differ in width or storage style.
