Mount wall lamps 60 to 66 inches from floor to fixture center, space them 6 to 8 feet apart along walls or 36 to 40 inches astride a mirror, and keep each at 300 to 500 warm lumens, so the walls carry the room's flattering light while the ceiling handles the working light.
Ceiling fixtures light floors; wall lamps light people. Rooms that feel warm at night almost always owe it to sources mounted at eye level, and the difference between flattering and glaring is a tape measure.

Where do they go, room by room?
| Location | Height (floor to center) | Spacing |
|---|---|---|
| Hallway | 60 to 66 in | 6 to 8 ft, staggered with art |
| Bedside | 30 to 36 in above mattress | one per side, reachable from the pillow |
| Vanity mirror | about 65 in | 36 to 40 in apart, flanking |
| Living room | 60 to 66 in | pairs framing fireplace or sofa wall |
Which lamp for which job?
Halls reward stone: the Brindisi alabaster lamp glows through real veining and a pair on a dimmer outperforms any downlight. Vanities want vertical diffusion, the Essence rectangle sconce lights a face from both sides without under-eye shadows. Bedsides like articulation: the Aimee pendulum swings its glow where the book is. And where the room needs one botanical note, the Lotus Leaf sconce does ornament and light in one move.

The rule that saves every install: tape a paper template to the wall and live with it for a day. Wall lamps are the easiest fixtures to hang and the most tedious to move one stud later.
Wall lamp placement guide: your questions
How high should wall sconces be mounted?
60 to 66 inches from the floor to the fixture's center in halls and living rooms, which places the glow at standing eye level. Raise to 66 to 72 inches under 9 ft or taller ceilings.
How far apart should wall lamps be spaced?
6 to 8 feet along open walls, or 36 to 40 inches apart when flanking a mirror or artwork. Closer than 3 feet the pools of light merge and the pair reads as one wide fixture.
Should bedside wall lamps replace table lamps?
They free the nightstand entirely: mount 30 to 36 inches above the mattress top, within reach from the pillow. Choose a design with its own switch or a swing arm so each side controls its own light.
Do wall sconces need wiring in the wall?
Hardwired sconces need a junction box, an electrician job if none exists. Many designs also work as plug-in with a cord cover, which installs with two screws and moves with you.
How bright should a wall lamp be?
300 to 500 lumens per fixture at 2700K. Wall lamps are layer lights, not main lights; several soft sources at eye level flatter a room more than one bright one.
