The Simple Size Rule (Fast Answer)
Example: a 30" wide frame looks best with a 15"–21" light.
This rule works for most living rooms because it produces a clean “gallery” look without making the light feel oversized. If you're lighting a very wide statement piece or a large gallery wall focal point, you can size up slightly for more even coverage.
How to Measure Your Artwork (Takes 30 Seconds)
Step 1 — Measure the frame width
Measure the full outside width of the frame (not just the printed image area).
Step 2 — Apply the 50–70% rule
Multiply your frame width by 0.5 to 0.7, then pick the closest light width.
Choose the Right Picture Light Size by Art Width
Use this quick matching guide for most homes. If you’re unsure, start in the middle of the recommended range for a balanced look.
Placement Matters: Height + Projection + Glare
Mounting height (best starting point)
Mount the picture light about 6–10 inches above the top of the frame. This helps create an even wash of light without harsh spotlight hotspots.
Avoid glare on glass
If your artwork has glass, aim the beam slightly downward. Adjustable heads make it easy to dial in the best angle.

Common Mistakes (and How to Fix Them)
Mistake #1: Choosing a light that’s too small
Too-small lights create a bright center and dark edges. Follow the 50–70% rule for even illumination.
Mistake #2: Mounting too high
Too high = harsh spotlight + shadows. Start 6–10 inches above the frame and adjust slightly.
Mistake #3: Not considering depth/projection
Deep frames need enough reach so the light clears the molding and spreads cleanly across the artwork.
Mistake #4: Forgetting glass glare
Aim the beam slightly downward and avoid “straight forward” angles. Adjustable heads help fine-tune glare.
FAQ: Picture Light Size & Installation
Should a picture light be the same width as the frame?
Usually no. A picture light looks most balanced when it’s about 50%–70% of the frame width. Matching the full width can look oversized unless you're lighting a very large statement piece.
What size picture light for a 24 inch wide picture?
A 12"–17" light usually looks best (about half to two-thirds of the frame width). If you want stronger, more even coverage, an 18" option also works well.
How high above artwork should I mount a picture light?
A good starting point is 6–10 inches above the top of the frame. This helps create a clean wash of light without harsh hotspots.
Will a picture light cause glare on glass frames?
It can, but glare is easy to control by angling the beam slightly downward and avoiding mounting too high. Adjustable picture lights help you fine-tune the best angle.
What’s the best picture light size for a living room gallery wall?
For a wider focal point (like one large piece or the center of a gallery wall), 24"–30" is often the safest range for an upscale “gallery” effect.
