Hang Tags: Small, Swinging, and Handled Constantly
Apparel hang tags are scanned at 20 to 30 cm, usually while the shopper holds the garment up. The tag itself is small — often just 50 × 90 mm — and it swings on its string, which means the code must decode quickly before motion blur sets in. Tags also endure constant handling: folding, pocketing, rain, and the general abuse of the shop floor. The sizing strategy here is simple — as large as the tag allows, with the shortest URL you can manage.
The 10:1 Rule of Thumb
At 25 cm the rule suggests 25 mm, but hang-tag real estate rarely allows it. With a short URL and a modern phone, 20 mm is the practical minimum — and the short URL is doing real work here, keeping the QR version low and the modules large and forgiving. If the tag design cannot spare 20 mm plus a full quiet zone, the code doesn't belong on the tag; put it on the packaging or the care label instead.
Recommended Size
Print at 20 × 20 mm (about 0.8 inches) on the tag's flattest area. On larger boutique tags (70 × 120 mm and up), step up to 25 mm for extra reliability. Anything below 18 mm on a swinging tag is a gamble — it may scan in the studio and fail in the store.
Substrate and Printing
Tags print offset or digital on thick tag board, usually uncoated for a premium tactile feel. Uncoated board wicks ink slightly and softens module edges, so don't push below 20 mm on uncoated stock; coated board holds sharper edges and is more forgiving at small sizes. Foil stamping and embossing are common on hang tags — keep every decorative process far away from the code area.
Placement and Practical Tips
- Keep the string hole and eyelet well clear of the quiet zone — a punched hole through the code is an obvious but remarkably common failure.
- Shoppers instinctively hold the tag still to scan; add "hold steady & scan" microcopy if the link matters to conversion.
- Link to size guides, styling videos, fabric care, or sustainability credentials — content that answers fitting-room questions at the moment of decision.
- Consider the tag's reverse: the front sells the brand, the back can carry the code without any design compromise.
- If the garment has a sewn-in fabric label too, don't duplicate the code — one scannable code per garment is plenty.
Common Mistakes
- Printing the code across the tag's fold or perforation, where it distorts the moment the tag flexes.
- Encoding a 150-character product URL with variants and tracking; use a short link and resolve details server-side.
- Forgetting that tags get handled, folded, rained on, and left in hot cars — uncoated tags in particular wear fast, so link to persistent pages.
- Decorative die-cuts or shaped tags that eat into the quiet zone.
