The one or two bedside wall sconces decision comes down to two things: how wide the mattress is, and how many people read in it. Buy one for a single sleeper, or for a mattress under about 56 in (142 cm) across. Buy a pair from roughly 60 in (152 cm) up, or wherever two people read at different times. Measure across the mattress before you weigh a single unit against a two-pack price.
The wiring deserves a thought before the price does. The Houseland Macaron sconce installs hardwired to a standard wall box (AC 90-260V), so a pair means two boxes, two backplates of two screws each, and one switching decision. Sorting that now costs a conversation. Sorting it later costs drywall.

Do I need one or two bedside wall sconces for my bed size?
Match the count to the measured width of the mattress first, then to the number of readers. Run a tape across the mattress at the pillow line and write the number down in inches. Bed size names are not a spec you can lean on, so let the tape settle it, then read the row that matches.
| Tape reading across the mattress | Usually sold as | Center-out offset for a pair | One or two? |
|---|---|---|---|
| Under 40 in (102 cm) | Twin or single | Not needed | One |
| 40 to 56 in (102 to 142 cm) | Full or double | 15 to 23 in (38 to 58 cm) | One, two only if both sides get used |
| 56 to 66 in (142 to 168 cm) | Queen | 23 to 28 in (58 to 71 cm) | Two |
| Over 66 in (168 cm) | King or split king | 28 to 35 in (71 to 89 cm) | Two |
| Any width, two sleeping levels | Bunk beds | One per level, at pillow height | One each |
| Any width, one open side | Daybed or corner bed | Wall side is unusable | One, on the open side |
The offsets in the third column are arithmetic, not taste: half the mattress width, minus about 5 in (13 cm) so each shade stays inside the mattress edge. Everything below is how you turn that number into two pencil marks.
How do I find the marks before I drill?
Work from the bed's center line, not the wall's center line, because your eye reads the bed as the axis in a bedroom. Six steps, one tape, one pencil.
- Measure the mattress width at the pillow line. Call it W. Do it with the bedding off, since a thick duvet adds 2 to 3 in (5 to 8 cm) of fluff that is not mattress.
- For a pair, halve W and subtract 5 in (13 cm). A 60 in (152 cm) mattress gives 25 in (64 cm) left and right of center. A 76 in (193 cm) mattress gives 33 in (84 cm). It is the same center-out logic behind how far apart sconces sit along a corridor, applied to a much shorter run of wall.
- For a single, divide W by 4. On a 54 in (137 cm) mattress that is 13.5 in (34 cm) off center, on the reader's side. That puts the pool over a pillow instead of over the middle of the duvet.
- Set the height off your shoulder, not the floor. Sit up in bed with a book, have someone mark the top of your shoulder on the wall, then put the fixture center 10 to 14 in (25 to 36 cm) above that mark. Mattress thickness and headboard height move a floor measurement around; your reading posture does not.
- Check the projection against the furniture. Houseland lists the dome design at 6.7 in (17 cm) from the wall and 5.1 in (13 cm) tall, and the cylinder at 5.1 in (13 cm) across, 5.5 in (14 cm) tall, reaching 9.4 in (24 cm) from the wall on its rubberwood arm. Compare that with your nightstand depth and how far the headboard stands off the wall.
- Tape a paper cutout at each mark and sleep on it. One night beside a paper circle tells you more than any diagram. Then commit the two screws.

Will one sconce reach the far side of a king bed?
No, not as reading light. Put a single fixture at W divided by 4 on a 76 in (193 cm) mattress and it sits 19 in (48 cm) off center. The far pillow center is then about 38 in (97 cm) away from the shade, and the far edge of the mattress about 57 in (145 cm) away. What lands over there is spill you can walk by, not light you can read a page by.
The swivel does not fix this. Each head rotates about 90 degrees and holds position, so it aims the beam without extending its reach. Shape changes the character rather than the distance: the cylinder throws the most focused beam, while the bell and dome spread a softer pool. Before you drill one hole and hope, run the paperback test. Hold a book where the far sleeper's hands would be, with a 12W bulb in the fixture, and see whether the text is comfortable or whether you are reading in your own shadow.
Does a single sconce look lopsided over the headboard?
Only if you leave the other side half finished. One fixture over a centered headboard reads as deliberate when the empty side carries height of its own: a stack of 3 or 4 books, a tall vase, a small framed print hung at the same height as the shade. Asymmetry fails when both sides are trying to be the same and one is losing, which is the same principle at work in styling sconces above a sofa.
If the bed is not centered on its wall, ignore the wall entirely. Set the offset from the mattress center line and the pair still looks right, even with 30 in (76 cm) of bare wall on one side and 6 in (15 cm) on the other.
What changes if I buy the pair: switching, wiring, cost?
Switching is the part buyers discover after install. Two hardwired fixtures fed from one switch come on together, so the partner who is asleep gets the light too. Two separately switched boxes give each side its own control, and that is decided in the wall, not in the shade. If you are unsure what is already behind the plaster beside your bed, start with what a wall box really is before you order anything.
The cost of a pair is not only the second fixture. It is a second box, a second run of cable if none exists, and the drilling done twice. The fixture half stays identical: the same two-screw backplate fixing applies to all three designs, so once the box is live, the second install is the easy hour of the day. Colors are worth deciding once, too, since the range runs to 3 shapes and 13 colors and a matched pair over one headboard is the safe call.

Macaron Bedside Wall Sconce, Adjustable Wood Base Wall Lamp, 3 Shapes 13 Colors
Hardwired to a wall box (AC 90-260V), so a pair leaves no cords down the wall, and each head swivels about 90 degrees to aim at a page. Choose bell, dome or cylinder in 13 colors, with a 12W warm light or 12W white light bulb, or no bulb if you already own an E26 LED.
View the macaron bedside sconce — 13 colourways & current priceDo bunk beds, daybeds, and corner beds change the answer?
Yes, and all three break the width rule for the same reason: the geometry of the sleeping position, not the size of the mattress. Bunks need one per level, each at that level's pillow height, because the upper bunk blocks any beam meant for the lower one. A single fixture hung high enough to clear the top bunk lights the ceiling and nothing anybody reads.
A daybed used as a sofa by day takes one fixture, set toward the end you lean against, with the head turned along the length of the mattress rather than across it. A bed pushed into a corner also takes one, on the open side, since a sconce on the corner wall points into 2 ft (61 cm) of dead space. If the wall you want is one you cannot open up, battery operated sconces are the honest fallback there, with their own tradeoffs.

Why does my bedside wall sconce flicker or buzz on a dimmer?
Almost always the bulb and the dimmer, not the fixture. The shade is painted iron on a rubberwood base with a metal swivel joint and no electronics of its own, so work through the parts that do the dimming, in this order.
- Read the bulb's own box for the word dimmable. Houseland lists the bulb choice as 12W warm light, 12W white light, or no bulb at all, and the E27 socket takes any standard US E26 LED, so if dimming matters, take the no-bulb option and pick the bulb deliberately. Which LED bulb fits walks through that choice.
- Check what the dimmer says it is for. Its instructions name the load types it handles and the minimum load it needs. A single 12W bulb is a small load, so that minimum figure is the one to look for.
- Swap the bulb and watch what follows. If the flicker moves to the other fixture with the bulb, you have your answer in 5 minutes and no tools.
- Run it at full brightness for an evening. Trouble that appears only in the bottom quarter of the dial points at the bulb and dimmer pairing rather than the wiring.
- Tighten the two backplate screws. A plate that is not pulled flat against the box can rattle audibly, and it reads as a buzz coming from the shade.
- Call an electrician if it survives all five. At that point you are looking at the circuit, not the lamp, and that is not a job for a screwdriver and optimism.

So what is the rule if I skip the tape?
One for a single sleeper, a twin, or a full. Two from queen upward, and two anywhere both sides of the bed get read in, whatever the width says. One per bunk level, one on the open side of a corner bed or daybed.
The tape still beats the rule, and it takes 20 seconds. What the tape cannot tell you is how many readers the bed has, and that is the half of this decision people get wrong: a 54 in (137 cm) mattress with two nightly readers wants a pair more than a 66 in (168 cm) mattress with one.
