Cozy Atmosphere
The right bedside sconce height is the center of the fixture at 60 inches from the floor for a standard bed with a mattress top at 24 to 26 inches, which puts the light about 20 inches above the pillow: close enough to light a page, far enough to feel architectural rather than clamped to the bed. Measure from the mattress if yours isn't standard, and aim for 18 to 24 inches above the top of it. I made every possible mistake before landing on that. The first pair went up at 72 inches, eye level when standing, which meant they lit the ceiling beautifully and my book not at all. The second attempt overcorrected to 48 inches, nearly nightstand height, and cast a strange upward glow that made the headboard look interrogated. The third pair is where they are now, and they've stayed there through two mattresses and one headboard. This post is the height and the reasoning, the horizontal placement that matters just as much, what changes with a tall headboard, a platform bed, a low ceiling or a reading habit, the switch position, the plug-in version, and the tape method that would have saved me two sets of patched holes.
The number that matters is the distance from the top of the mattress to the center of the light, because that's the geometry of reading in bed: sit up against the headboard and your eyes are roughly 26 to 30 inches above the mattress, your book is at 10 to 15, and a light 18 to 24 inches above the mattress lands on the page from slightly above the eye without shining into it. A standard bed with a mattress top at 24 to 26 inches puts that at 60 inches from the floor, give or take. A tall bed with a thick mattress and a box spring at 30 inches wants the sconce at 64 to 66. A low platform bed at 18 inches wants it at 54 to 56. Sixty is the number for most beds, and the mattress measurement is the rule that produces it.
I see sconces mounted at the right height but too far out from the bed, pooling light on an empty wall instead of the nightstand, or too far in, over the pillow, where the light lands on the sleeper instead of the reader. Position each sconce so its center aligns with the center of the nightstand below it, or, without nightstands, 24 to 30 inches out from the center of the bed on each side. For a queen bed with 20-inch nightstands, that puts the sconces about 68 inches apart, center to center. If the sconce has an arm, the arm should reach toward the bed so the shade sits over the inside edge of the nightstand, where the book is. Ours are centered on 22-inch nightstands, 72 inches apart, and the shades reach 6 inches inward.
A tall upholstered headboard, 48 inches or more, moves the sconce up so it sits above the headboard's top edge by at least 6 inches, or mounts it on the headboard's outer edge if the headboard is wide enough. A low headboard, or none, and the sconce follows the mattress rule. A headboard with wings or a canopy needs the sconces outside it, which means further apart, and a swing-arm to bring the light back in. Our oak headboard is 40 inches, the sconces at 60 sit 20 inches above it, and the light washes down the wood, which is one of the reasons the bedroom makeover reads as finished.
The mattress rule doesn't change with the ceiling, but the fixture's size does: under an 8-foot ceiling, a sconce over 12 inches tall crowds the wall, and the shade should be small enough that the top of the fixture is below 70 inches. Our ceilings are 8 feet and the sconces are 9 inches tall with 5-inch shades, mounted at 60, tops at 64. In a room with a sloped ceiling, mount on the wall that's vertical, and if that's not the headboard wall, use a swing-arm from the side wall. In a very small bedroom where the bed is against a side wall, one sconce on the open side and a low lamp on the wall side, both at the same height from the mattress, reads as intentional; two sconces with one pinned against a wall does not.
A switch you can reach from the pillow, or the sconce is decorative. Hardwired sconces should have a switch on the fixture itself, or a wall switch beside the bed at 36 inches, not by the door. Ours have a rotary switch on the backplate and a dimmer on the wall by the bed, so each side dims on its own; my husband reads at 60 percent and I read at 30, and neither of us has to get up. The single most common bedside sconce complaint I hear from friends is "we never use them," and every time it's because the switch is at the door. A plug-in sconce solves this with an inline switch on the cord, kept within reach, or a plug-in dimmer at the outlet behind the nightstand.
A plug-in sconce mounts at exactly the same height; the only differences are the cord and the mounting. The cord drops straight down behind the nightstand to the outlet, in a fabric cover or a paintable channel, and it's invisible once the nightstand is in place. Mounting is two screws into anchors, or, in a rental, adhesive strips rated for four times the fixture's weight, for a sconce under 3 pounds, which most bedroom sconces are. Our guest room has plug-ins because the wall had no boxes and I wasn't opening plaster for a room used eight nights a year, and guests can't tell. The rechargeable versus plug-in test covers the cordless option, which goes at the same height and charges every couple of weeks.
2700K, 90 CRI, dimmable, 400 to 500 lumens per sconce; the reasoning by room is in the bulb test. A fabric or opal shade rather than clear glass, because a bare filament at 60 inches is in your line of sight when you turn over, and clear glass sconces belong in a hall. If one of you reads small print, put a brighter bulb on that side, 600 lumens, rather than mounting that sconce lower, which is the mistake I made second. Warm-dimming bulbs, which go amber as they go down, are the nicest thing that has happened to bedside light since the dimmer, and both of ours have them.
A swing-arm sconce, the kind with a jointed arm that pulls out over the bed, mounts a little higher, 62 to 64 inches, because the arm brings the shade down and in toward the book; it's the choice for a serious reader and for a bed wider than the nightstands. A fixed sconce with a downward shade, which is what we have, goes at 60 and stays put, and it's the choice for a calm wall and a reader who doesn't move the light around. An up-and-down sconce, with light out of the top and the bottom, goes at 58 to 60 and lights the headboard wall as well as the page, which is the one to pick if the sconces are also the room's evening light and there's no other lamp. A picture-light style, long and narrow above the headboard, is a different thing and goes 6 inches above the headboard's top edge, and it lights the wall, not the book. Whichever style, the shade's lowest edge should end up 16 to 20 inches above the mattress, and the style decides where the mounting plate goes to achieve that.
Too high (65 inches and up on a standard bed): the light hits the wall and the ceiling and misses the page; fix with a swing-arm or by remounting. Too low (under 54): the glow comes up the headboard and into your eyes; remount. Too far apart: the light pools on empty wall; center on the nightstands. Too close, over the pillows: the sleeper gets the light; move out to the nightstand centers. Matching heights measured from the floor on a floor that isn't level, which in a 1920s cottage is every floor: measure both from the mattress top. One sconce in a room with two people: add the second. And a switch by the door, which is the mistake that makes all the others irrelevant because the sconce never comes on.
A guest room sconce goes at the same mattress-plus-20, with the switch on the fixture, because a guest won't look for a wall switch in the dark and shouldn't have to; ours are plug-ins with rotary switches and a card in the nightstand drawer saying "the light is on the lamp." A child's bed with a low mattress at 18 inches takes the sconce at 54 to 56 inches, on a fixture that's cool to the touch and, for a young child, a plug-in with the cord tucked behind the headboard rather than dangling. Bunk beds take a sconce per bunk, each at mattress-plus-18 because the ceiling is close on the top bunk, each with its own switch, which is the only arrangement that has ever kept peace in a shared room, and I say that as the mother of two who shared for six years. The number moves with the mattress. The rule doesn't.
Cut painter's tape to the size of the backplate. Stick it to the wall at 60 inches to center, or at your mattress-plus-20. Lie in bed with a book for two nights and look at it. Move it if it's wrong. Then hold the actual fixture against the tape, because the shade changes where the light will land, mark the holes through the tape, and drill. It costs $3 and two evenings, and I patched four holes and repainted a wall before I learned it, which my husband mentions whenever I say the word "sconce." The same method works for a plug-in on strips, except the strips go where the tape was and you skip the patching altogether.
Measured the mattress top: 25 inches. Added 20: 45 from the mattress, 60 from the floor, marked with tape at center on both sides. Measured the nightstands: 22 inches wide, 3 inches from the bed on each side, so the centers were 36 inches out from the bed's center line and 72 inches apart. Tape up for two nights. Held the fixtures to the tape and found the shades would sit an inch too far out, so moved both marks an inch in. Electrician set the boxes at the marks and put a dimmer on each side. Sconces on, bulbs in, book open, and the light landed on the page from just above my eyeline, which is what 20 inches above the mattress is for. Two mattresses and a headboard later, nothing has moved, and nothing has needed to.
Since the third pair went up at 60 inches we've changed the mattress once (up 2 inches, which the arms absorbed) and the headboard once (oak, 40 inches, which the height suited by luck). The sconces haven't moved. Every friend who's asked has been given the same answer: measure the mattress, add 20, center it on the nightstand, put the switch where your hand is, and tape it first. It's the bedroom lighting rule I wish I'd known before the first pair, and it's the reason the bed looks like someone thought about the space rather than just decorated it, which is the whole difference between a room and a bedroom.
