Measure from the floor to the top of your mattress, with the bedding on. Write the number down. That single measurement decides whether a nightstand works, and the two most-quoted US guides disagree about what it usually comes out to by as much as six inches.
Wayfair’s measuring guide puts the answer at 24 inches: “Since most beds are 24″ at the top of the mattress,” and its FAQ narrows the range to “approximately 24″ to 25″ at the top of the mattress.” Lulu and Georgia’s nightstand FAQ says something quite different: “Most mattresses (with a box spring or platform) sit between 25 and 30 inches from the floor.”
One of those numbers makes a 19.7-inch nightstand a near miss. The other makes it a foot too low. Both guides end up telling you the same thing — measure your own bed before you order — which is why that sentence opens this article.
Our nightstands, by the inch
Every height below is the assembled height on the product page, cross-checked against the supplier spec sheet. Width and depth follow the order the pages use.
| Nightstand | Assembled height | Width × depth | Material on the listing |
|---|---|---|---|
| Two-Drawer Nightstand in Rubberwood | 19.9 in | 11.8 × 15.3 in | solid rubberwood |
| Fluted Nightstands, Set of 2, Walnut | 19.7 in | 11.8 × 15.8 in | MDF |
| Fluted Nightstands, Set of 2, White | 19.7 in | 11.8 × 15.8 in | MDF |
| Bedside Table with Drawer and Open Shelf | 19.7 in | 11.8 × 15.8 in | solid wood |
| Modern Bedside Tables, Set of 2 | 23.4 in | 15.4 × 11.4 in | engineered wood |
| Side Table with Charging Station, Walnut | 24.4 in | 23.6 × 11.8 in | MDF body, two USB ports and two outlets in the top |
Four of the six sit at 19.7 or 19.9 inches. Wayfair’s own taxonomy files anything under 23 inches as a low nightstand, aimed at “lower bed frames, such as modern platform beds.” No point dressing that up: most of what we sell is in the low category, and the real question is which beds that suits.
The 3-inch window, applied
Wayfair’s rule is the most usable version of the consensus: the top should be level with the mattress top “or no more than 4″ higher,” and within 3 inches of it. Applied literally, that gives a range of mattress heights each piece can serve.
| Nightstand height | Mattress top it works with (within 3 in) |
|---|---|
| 19.7 in | 16.7 – 22.7 in |
| 19.9 in | 16.9 – 22.9 in |
| 23.4 in | 20.4 – 26.4 in |
| 24.4 in | 21.4 – 27.4 in |
Run Wayfair’s 24-inch figure through that table and the 19.7s come out 4.3 inches short, outside the window. The 23.4-inch model lands 0.6 inches under; the 24.4-inch charging table lands 0.4 inches over. Run Lulu and Georgia’s 25 to 30 range instead and nothing in the low group is close, while the 23.4 and 24.4 pieces only work at the very bottom of it.
This is the part that decides a return. A platform frame with slats 11 to 13 inches off the floor and a 10-inch mattress puts your mattress top at roughly 21 to 23 inches, where a 19.7-inch nightstand sits about level with it. That is the setup these pieces were drawn for. A box spring under a thick mattress, or a pillow-top that adds two or three inches, puts you at 25 inches or more — and then a 19.7-inch table leaves your glasses and your water below the edge of the mattress, where you reach for them in the dark without looking.
Where the low height actually costs you
Three places, all of them at night:
- The lamp. A low table with a tall lamp puts the shade level with your face when you lie down. Check the lamp’s total height against the table height before you commit.
- Reading in bed. Propped on pillows you sit higher than the mattress top. A table level with the mattress when you are flat is below your hand when you sit up.
- Reaching without looking. This is the whole difference between 19.7 and 23.4 inches: about four inches of downward reach, every night, in the dark.
None of that is a defect. It is what the number means, and it is why the pages list height first rather than last.
Width runs out before height does
Height gets the attention, but in a narrow bedroom width decides whether the piece goes in at all. Wayfair treats anything under 21 inches wide as a narrow nightstand, “best suited for twin- or twin XL-size beds,” and asks for 3 to 6 inches of gap between the nightstand and the edge of the bed.
Four of our five nightstands are 11.8 inches wide. Add a 3-inch gap and you need 14.8 inches of clear floor beside the mattress; add 6 and it is 17.8. That fits a small bedroom where the bed is already close to a wall. It also means a genuinely small tabletop — a lamp and a glass, or a lamp and a phone, not a lamp, a stack of books and a clock. The 15.4-inch-wide Modern Bedside Tables give you about 3.6 inches more surface, which is the difference between a wide lamp base fitting and not.
Depth is the other half. Wayfair calls 12 to 16 inches deep “shallow” and recommends it for small spaces; the 15.8-inch-deep models are inside that band. The 23.4-inch Modern Bedside Tables are 11.4 inches deep, because the width went into the front face instead — so measure a hardback and a lamp base before assuming both sit fully on it.
If your mattress top is 24 inches or more
Then skip the 19.7s and go to the 23.4-inch Modern Bedside Tables, which Lulu and Georgia’s “22–24 inch range” for lower platform beds describes almost exactly. For a bed at 25 inches or above, the Side Table with Charging Station is the tallest thing we make at 24.4 inches, and it puts two USB ports and two outlets in the top.
Above 27.4 inches, nothing we sell reaches. A box-spring bed with a thick mattress needs a 28-to-30-inch nightstand — a different product, not a different model of this one. Better to say that than have you buy a 19.7-inch table and return it.
The two-minute check before you order
- Bedding on. Measure floor to mattress top at the spot where the nightstand will sit.
- Compare with the table above. Inside 3 inches either way is comfortable; more than 4 inches below and you will feel it nightly.
- Measure the gap from the mattress edge to the wall or closet door. You need 3 to 6 inches of gap plus the nightstand’s width.
- Check the height of the lamp you actually plan to put on it.
