Check your artwork at actual size — the 5-minute test before you order

Every merch format shrinks your artwork to a size that looks fine on a 27″ screen and vanishes in reality. The fix isn’t more DPI — it’s ten minutes with a printer and a ruler, before you order anything.

The short answer: print your artwork at 100% of the final size, hold it where the product will actually be seen, and check four things — smallest text, thinnest line, silhouette, and busy detail. Anything that fails there will fail worse in production, because production adds its own losses on top of yours.

The 5-minute test

1. Set up at true size. Print the artwork at exact final size (100% scale — a template or a ruler check tells you the printer isn’t scaling). Low-fi is fine: a desktop printer shows layout failures even if it can’t show colour or resolution. If you can’t print, measure the artwork on screen at its true dimension — but print beats screen for judging lines under fit.

2. Hold it at use distance. Don’t look at the printout on the desk. Hold it where the product lives: a keychain on a bag strap at chest height, a magnet on the fridge at reading height, a sticker on a laptop lid seen from the side of a table, a badge on a lapel seen from a metre away. Distance is what actually decides legibility — not zoom.

3. Check the four killers, in order:

• The smallest word. Read it at use distance. If it’s the one doing the joke or the job and you’re squinting, it’s gone — on a small acrylic charm or badge, most type that isn’t obviously big enough is too small.
• The thinnest line. Look for what nearly disappears at 100%: outline strokes, hairline rules, delicate flourishes. When print adds its own softness, those lines merge.
• The silhouette. Squint, or blur your eyes. If the shape itself stops reading, the design stops working — especially for cut-out products where the outline is the design.
• The busy detail. Look honestly at what remains of a scene at true size. If the composition collapses into noise, the format wants an icon, not the scene.

4. Fix at the source. Something failed? Move the text up a notch, simplify the busy area, thicken the minimum line, or accept that the format is asking for a simplified version of the design. Better to learn it on a printout than on a production run.

5. Record what changed. Keep the true-size printout with your order file. It’s the reference against the proof later — and it’s the honest answer to “why did I size it this way?” when the supplier asks.

What the test can’t tell you

A paper printout is not a production sample. It shows geometry — size, spacing, silhouette — but it does not show:

• Colour. Screen, printer and production inks are different systems. RGB neon on a screen is not CMYK on a charm — see RGB vs CMYK
• Ink on the actual surface. White ink on clear acrylic, effect finishes, enamel — each changes the look (white ink on clear, sticker finishes)
• Material, weight, finish and hardware. No printout checks a dome, a pin back or a magnet’s hold
• Vendor-specific numbers. Bleed, safe area and minimum line weight are set by the production line; your test assumes your judgement, the supplier’s spec sheet is the other half (cut lines, bleed and safe area)

For all of those, the honest gate is the physical sample — which is why this test is a pre-filter, not a substitute. Run it, and the sample round becomes a confirmation instead of a discovery.

The test is five minutes, and the artwork readiness checklist turns its result — plus everything else a quote needs — into one message. When it passes, send the artwork: size decisions made against reality are what the quote can act on.
