End table height is where most people guess wrong in both directions. Too short and the surface is a reach. Too tall and you are looking up at it from the sofa. The measurement that matters is exactly 2 to 3 inches below your sofa arm, and this guide explains what to do when your sofa arm does not cooperate with that number.
This is the formula, the room-by-room breakdown, and the specific dimensions of the UNFNSHED tables so you can stop estimating and start measuring.
The formula that works in every room
The 2-to-3 Inch Rule
An end table should sit within 2 to 3 inches of your sofa arm height. If your sofa arm is 24 inches from the floor, your end table should be 21 to 26 inches tall. This range lets you set down a drink, a book, or a phone without straining your arm up or bending it uncomfortably down. Standard sofa arm heights run from 22 to 25 inches. Standard end table heights run from 22 to 30 inches. Most rooms have more flexibility than people think.

Living Room: Beside the Sofa
Standard sofa arm heights land between 22 and 25 inches. Target an end table between 22 and 28 inches. If your sofa is low (contemporary platform sofas can sit at 14 to 16 inches seat height with 20-inch arms), size down accordingly. The goal is the surface height matching or just below the arm height when you are seated.
Bedroom: Beside the Bed
Here the measurement changes. You want the nightstand or side table surface within 2 to 3 inches of your mattress top. Measure from the floor to the top of your mattress. Standard mattresses on platform frames sit at 20 to 24 inches. Add a mattress topper and you can push that to 28 or 30 inches. The UNFNSHED Nightstand is 22 inches, which works for most platform beds without toppers and is exactly right for traditional box spring setups at 24 inches.
Home Office: Beside a Desk Chair
A side table beside an office chair functions as an overflow surface. Your desk is likely 28 to 30 inches. Match that height so you can slide papers or a keyboard across without lifting. The UNFNSHED Side Table at 15 inches is too low for this use. The Nightstand at 22 inches is the closest option for a desk-level auxiliary surface.

The 2-to-3-inch rule is a guideline, not a constraint. There are three situations where you can ignore it entirely:

End table height questions
What is the standard height for an end table?
Standard end tables run from 22 to 30 inches tall. The most common height is 24 to 28 inches, designed to match standard sofa arm heights. Shorter modern tables (15 to 20 inches) are made for low-profile sofas and platform furniture.
How tall should a side table be next to a sofa?
Within 2 to 3 inches of your sofa arm height. Measure your sofa arm from the floor, then choose a table that lands in that range. If your sofa arm is 24 inches, a table between 21 and 27 inches is correct. Either direction works as long as you stay within the window.
What height should a bedside table be?
Within 2 to 3 inches of your mattress top height. Measure from the floor to the top of your mattress (not the frame). Standard mattress tops land at 20 to 24 inches on a platform frame. Add a mattress topper and you might reach 26 to 30 inches.
Can an end table be higher than the sofa arm?
Yes, by up to 2 to 3 inches. A table that is slightly taller than the sofa arm still works functionally and looks intentional. A table that is 6 or more inches taller than the arm creates an awkward reach and visual mismatch.
Is 15 inches too short for an end table?
It depends on your sofa. For a low modern sofa with an arm height of 16 to 18 inches, 15 inches is correct. For a traditional sofa with a 24-inch arm, 15 inches is about 9 inches too short. Measure your sofa arm before buying any table.
