A nightstand should sit roughly level with the top of your mattress — usually 24 to 28 inches tall — and each one adds about 18 to 24 inches to the bed’s width. Matching the height keeps a lamp, phone, or glass of water within easy reach, and knowing the width tells you whether nightstands fit your room. Here is how to size them.
Nightstand Size Guide
| Dimension | Typical range |
|---|---|
| Height | 24–28 in (match your mattress top) |
| Width | 18–24 in (16–18 in for tight rooms) |
| Depth | 16–20 in |
| Gap from bed | 2–6 in |
What to Look For When Buying a Nightstand
Height matters most, then storage and footprint.
- Height — within a couple inches of the mattress top so you can reach a lamp and phone
- Storage — a drawer hides clutter; an open shelf shows books and decor
- Width — fit it in the clearance beside the bed without blocking the walkway
- Charging — some have built-in USB ports for an overnight charge
- Material — solid tops resist water rings from a glass or mug
| Option | Typical US price | Best for |
|---|---|---|
| Basic | $40–150 | Budget |
| Quality wood | $150–500 | Most bedrooms |
| Designer / smart | $300–900 | Charging, statement |
Prices are typical US ranges and vary by size, material, and brand — ballparks, not quotes.
Match the Height to Your Bed
The goal is for the nightstand surface to line up with the top of your mattress, so you can reach a lamp or phone without stretching up or down. Measure your finished bed height — floor to the top of the mattress, which is usually 20 to 25 inches — and pick a nightstand within a couple of inches of that. Taller beds need taller nightstands.
Will It Fit? Check the Width
Each nightstand adds its width to the bed’s footprint. A Queen (60 inches) with an 18-inch nightstand on each side spans 96 inches — eight feet — before you add any walkway. In a tight room, use slim 16-to-18-inch nightstands, or a single one on the side you use most. Check whether your room can take them with the Bed Size Calculator.

Frequently Asked Questions
A nightstand should be about 24 to 28 inches tall so its surface lines up with the top of your mattress. Measure your finished bed height and match it within a couple of inches — taller beds need taller nightstands so a lamp or phone stays within easy reach.
Most nightstands are 18 to 24 inches wide. In a tight room, choose slim 16-to-18-inch models so they do not crowd the walkway. Remember each nightstand adds its width to the bed’s footprint, so include both when you check whether they fit.
Leave a small gap of about 2 to 6 inches between the nightstand and the bed. Close enough to reach easily, but with a little space so you are not knocking into it. A flush fit works too if you prefer, as long as the surfaces are level.
