Circular QR Codes for Packaging and Stickers: 5 Ways to Make Them Earn Scans
Why circular QR codes sit naturally on round labels and where to use them — jar lids, tins, caps, stickers, seals, and buttons — plus print specs so they scan.
A square QR code on a round jar lid always looks stuck on. A circular QR code — also called a round QR code or circle QR code — feels like it was designed for the surface. The dots fill the circle, the rim ring doubles as the cut line, and the three finder eyes still scan like any QR code.
Try it: Circular QR Code Generator — make a circular QR code where the dots fill the circle, pick a seal/coin/button frame, download a free PNG. Same tool at

Why circular QR codes win on physical product
- No awkward corners — the artwork flows to the circular edge instead of leaving white square corners on a round label.
- Built-in cut line — the rim ring tells the die-cutter (and the customer) where the sticker ends.
- Same scannability — finder eyes, data, and quiet zone stay intact. Decorative dots outside the quiet zone are ignored by cameras.
- Dynamic when you need it — save to Qrblox, then re-point the same printed code to a new URL and track scans without reprinting.
5 places circular QR codes earn scans
1) Jar lids, candle tins, and bottle caps
Link to ingredients, how-to-use video, refill subscription, or care instructions. Diameter 2.5–3.5 cm, dark dots on white, on the flat center — not on the curved rim. Shorten the URL for fewer, larger modules.
2) Circular stickers and seals
Tamper seals, thank-you seals, warranty seals. The Safety Seal template (green ring) reads as verified; Product Seal reads as brand. Leave the white quiet zone clear — do not wrap text into it.
3) Hang tags, buttons, and badges
Apparel hang tags and event badges. The Coin (gold) and Glossy Button templates turn the code into a design element people want to scan, not hide.
4) Coffee cups, vinyl sleeves, and coasters
Small round surfaces where a square code would dominate. Use a short dynamic link and test at actual viewing distance — arm’s length for a cup sleeve.
5) Weddings, events, and promo drops
Circular codes on round invitations, coaster invites, or sticker sheets that look like part of the design. Link to RSVP, photo album, or playlist — swap the destination later via the dynamic code.
Specs that print right the first time
- Minimum diameter: 2 cm (0.8 in) close range; 3–4 cm for retail shelf labels; scale up for posters.
- Contrast: Dark dots on white. No light-on-dark dots, no pastel dots.
- Quiet zone: Keep it — it is the white ring around the code. No logo or border over it.
- Form factor: Export and print at 1:1 — never stretch to an oval.
- Stock test: Print one on the actual sticker stock, scan with iPhone + Android at real distance before you run the batch.
- Vector for press: Free PNG is 1024px (good to ~8–9 cm at 300 DPI). For foil/emboss, save to Qrblox and export SVG/EPS from the dashboard.
