The right height of the bedside lamp matters for bedroom comfort. If lamp too short or too high it can blind, be hard to reach or simply look out of place. You should choose the height of bedside table lamp so that it fits with the nightstand and the mattress.
Normally bedside lamps have height between 24 and 30 inches. The lamp should reach the height of nightstand plus 2 to 3 inches. For instance, for 24-inch nightstand, lamp of around 26 to 27 inches works.
How High Should Your Bedside Lamp Be
When nightstand is 24 to 30 inches, ideal lamp height is 27 to 32 inches. Table lamps can be 1.5 times the nightstand height, usually between 24 and 36 inches.
For 27-inch nightstand works lamp of 27 to 32 inches, perfect range to aim for.
The lampshade top stays at eye level when you sit on the bed. Like this you have good light for reading and other tasks. It matters especially for reading in bed, becuase the light should not hit the head or blind the eyes.
Unless bed or headboard is extremely low, lamps should be around 22 to 27 inches. The shade bottom stays here, where you keep book during reading. Bedside lamps are at least 22 inches high, and shade is usually 40 percent of total height.
Without too much math, the lamp top stays between 58 and 64 inches from the floor. Most bedside tables are around 28 inches high, which leaves at least 30 inches for the lamp itself.
The bedside table should match the mattress height or differ by one or two inches. Not only the mattress height matters. Also the bed frame.
The final bed height is better for choosing bedside tables. The lamp matches roughly the headboard. Ideally it fits with that, and good rule: lamp around two-thirds of headboard height.
Weird look if lampshade is higher than the headboard.
King size bed benefits from higher lamps for balanced look, while queen size fits with a bit shorter. If bed and bedside tables are very large and high, lamps require bigger scale. They should seem big enough for the bed and nightstands.
Except height, think style and use of bedside lamp. Right balance between lamp size and nightstand makes nice arrangement (like good shoe choice for outfit).
Lamp around 2 feet with small shade works well. It is high enough for reading without long shadows, and small base leaves space onnightstand for phone, book or other small items.
