The best diamond painting light pad, matched to the size of your canvas

A light pad makes every symbol readable, but the size you pick decides how often you'll shuffle the canvas. Here's a to-scale chart and the best pads at each size.

How we pick Updated · We earn a commission when you buy through our Amazon links.

For most diamond painters, the best light pad is an A3 size: its lit area covers most of a typical 12x16 inch canvas, so you rarely move the canvas. The Ratukall A3 light pad kit is our pick because it's a best seller that also includes storage, trays and a roller. If you paint small kits or on the go, an A4 pad like the Ratukall A4 costs less and fits in a tote bag.

How we picked these light pads

  • Sales and ratings on Amazon on October 3, 2026, from tracing-board giants with tens of thousands of ratings to diamond-painting-specific kits.
  • Lit (working) area, not just the paper size. "A4" and "A3" describe the board, and the lit area is smaller. Where a seller lists the working area, we use it.
  • Brightness control, power and extras: dimming levels, USB vs rechargeable, stands, clips and included tools.

This is a "How we pick" guide based on listings, sales and owner ratings. We didn't measure brightness ourselves, so lux figures are the sellers' own. How we research.

A4 vs A3 vs A2: what each size actually covers

Light pad sizes borrow paper names: A4 is 8.3 x 11.7 inches, A3 is 11.7 x 16.5 inches and A2 is 16.5 x 23.4 inches. The lit area is a bit smaller than the board. Here's how those lit areas compare with the most common kit, a 12x16 inch canvas:

Light pad lit areas compared with a 12 by 16 inch canvas To-scale outlines: a 16 by 12 inch canvas, an A4 pad lit area of about 12.5 by 8.6 inches covering roughly half of it, an A3 lit area of about 15.4 by 11.9 inches covering most of it, and a nominal A2 board of 23.4 by 16.5 inches covering all of it. A2 board (nominal 23.4 x 16.5 in) 12 x 16 in canvas A3 lit area ~15.4 x 11.9 in A4 lit area ~12.5 x 8.6 in What that means A4: lights about half of a 12x16 canvas. Move it 1–2 times. A3: lights nearly the whole 12x16 canvas. A2: room for 16x20 and bigger kits, but it's a big board. Drawn to scale (16 px = 1 in). Lit areas from the TOHETO A4 and Zocelight A3 listings; other brands differ slightly. A2 shown at nominal board size.
The canvas outline is a standard 12x16 inch kit. An A3 lit area covers most of it; an A4 lit area covers about half.

What matters when you buy a light pad

Lit area over board size

Compare the working or illuminated area when the listing gives it. Two "A4" pads can differ by an inch or more of lit space.

Adjustable brightness

Full brightness can make light-colored symbols harder to read, while dim settings help on pale canvases. Three levels is the minimum; stepless dimming is nicer.

Button placement

Touch buttons on the front edge get bumped by wrists. Side or corner buttons, like the TOHETO's, avoid that.

Corded vs rechargeable

USB pads are cheaper and fine at a desk; you can power them from a phone charger or power bank. A built-in battery is worth paying for if you paint on the sofa.

A stand for your neck

Painting flat on a table means hunching. A stand that tilts the pad lets you sit upright for longer sessions.

Light pad or desk lamp?

A daylight desk lamp lights the canvas from above, which helps you see the drills you've placed and their sparkle. A light pad lights the canvas from below, which makes the printed symbols stand out, especially on dark or busy designs. Many regular painters use both: the pad for reading symbols and a lamp for checking finished sections. If you can only buy one, buy the pad, because reading symbols is where beginners lose the most time and strain their eyes.

One tip: if symbols on very pale areas look washed out, turn the pad's brightness down rather than up. Too much light can make faint symbols disappear.

The bottom line

Buy the Ratukall A3 kit if you paint standard 12x16 inch kits: it's the right size and comes with nearly everything else you need. Choose the Ratukall A4 for small kits, kids or a tight budget, the Zocelight A3 for cord-free painting, and an A2 pad only if you regularly paint 16x20 inch or bigger. Shopping for someone else?

Questions people ask

Do you need a light pad for diamond painting?
No, but most regular painters end up buying one. A light pad shines through the canvas so the printed symbols are easy to read, especially dark colors and small symbols. It also reduces eye strain in the evening.
What size light pad do I need for diamond painting?
Match it to your usual canvas. An A4 pad covers roughly half of a 12x16 inch canvas, so you'll move the canvas once or twice. An A3 pad covers most of a 12x16 inch canvas. For 16x20 inch and larger kits, A3 still works if you shift the canvas, or go A2.
Is A3 or A4 better for diamond painting?
A3 for most painters. Most adult kits are 12x12 to 12x16 inches, and an A3 pad's lit area covers most of that canvas. A4 is cheaper and more portable, which suits small kits, kids and travel.
Can you use any tracing light box for diamond painting?
Yes. Diamond painting light pads are LED tracing boards. Look for adjustable brightness, a thin body and a lit area that suits your canvas. Diamond painting versions often add a stand, clips or storage.
Are rechargeable light pads worth it?
If you paint on the sofa, in bed or away from an outlet, yes. Rechargeable pads have a built-in battery; the Zocelight A3 lists about 5 hours per charge. Corded USB pads are cheaper and fine at a desk.
Does a light pad get hot under the canvas?
LED light pads give off little heat compared with old fluorescent light boxes, and painters use them under canvases for hours. Still, turn the pad off when you finish a session and store the canvas off the pad and out of direct sun.
