Table lamps usually bring up a few simple questions. Mostly about where they should go and how tall they should be once they’re sitting on a table or nightstand.

Some questions are about placement. Should a lamp sit beside a sofa, on a bedside table, or on a console in the entry? Others are about height. How tall should the lamp be so the shade sits comfortably when you’re sitting nearby? And sometimes it’s just about light. Is the lamp meant to brighten the room a little, or mainly light the spot next to the chair or bed?

The good news is that table lamps are pretty easy to figure out. A few basic things tend to guide the choice: the height of the table, where people are sitting, and how the light will actually be used. Once those pieces make sense, the lamp usually feels right pretty quickly.

The questions below cover the things people most often ask when choosing or placing a table lamp. A few sizing tips, a few placement ideas, and some practical details that make it easier to get the light where you want it. Nothing complicated. Just clear answers so the lamp ends up in the right spot.
