End Table Dimensions: Standard Heights, Widths & Depths
What size is a standard end table? Heights cluster at 22–26 inches, widths run 12–30, and the right pick is set by the seat beside it — not a catalog average. Here are the real ranges, the one measurement that overrides them, and how to size a table to a tight slot.
The standard ranges (and why they're a starting point, not an answer)
Ask for "standard end table dimensions" and the honest reply is a range, not a number, because the table has to match the seat it serves:
- Height: 22–26 inches for most, 18–30 across the full market.
- Width / diameter: 12–30 inches — 12–18 for a tight slot, 18–24 for the common case, 24–30 where it doubles as display space.
- Depth: 12–24 inches — deep enough for a lamp base plus a glass (a lamp footprint is often 10–11″ square), shallow enough to clear your knee.
Those are the numbers to shop against, but only after the one measurement that overrides all of them.
Height is set by the arm, not by "standard"
An end table works when the tabletop lands level with the arm of the seat beside it, or within about two inches below — that's the reach that lets a glass come down by feel. Sofa arms mostly run 22–26 inches, which is exactly why most end tables do too. But a low modern sofa can have an 18-inch arm and a rolled-arm traditional piece can reach 30, so the "standard" only holds if your sofa is standard. Measure your arm, floor to top, first; the full rule and the armless-sofa case are in end table height: match the arm.
Width and depth are set by the slot
Height decides whether the reach is comfortable; width and depth decide whether the table physically fits:
- Between a sofa and a wall or armchair, measure the open slot and subtract about an inch of breathing room each side. The 12–16-inch narrow end of the range exists precisely for these gaps.
- Depth should sit flush with, or just short of, the seat's front edge. Deeper than the cushion line and you'll catch a knee walking past.
- Round end tables trade a corner for a smaller usable top: a 20-inch round holds less than a 20-inch square, so size up a couple of inches if a lamp and a drink both need to live there.
Standard end table dimensions at a glance
| Dimension | Tight slot | Common | Generous |
|---|---|---|---|
| Height | 18–21″ | 22–26″ | 27–30″ |
| Width / diameter | 12–17″ | 18–24″ | 25–30″ |
| Depth | 12–15″ | 16–20″ | 21–24″ |
Read height off the arm first, then take width and depth from the slot. A table that hits all three is a fit; one that misses height is a table you reach down into a lamp for.
Nesting and C-tables bend the rules on purpose
If the numbers won't reconcile — you need the surface but not the footprint — a C-table slides its base under the sofa so the top cantilevers over your lap at seat height, taking almost no floor. Nesting tables stack into one footprint and pull apart when guests arrive. Both are sized by the same arm-and- slot logic; they just spend their footprint differently.
Every end and side table on Alcovio lists true height, width, and depth, so once you have your arm measurement and your slot width, browse end tables and filter to the three numbers that decide it.
