From a printed card to your profile in one scan
Someone is standing at your stall holding a coffee in one hand. They like the work, they mean to look you up later, and later never comes. A code printed on the price card removes the typing and the misremembered username. Paste your profile link below, choose the colours, and download a file you can actually give to a printer.
It is a link code and nothing more exotic. The pattern holds one address, usually instagram.com followed by your username, and a scan behaves exactly like tapping that link in a message. The camera shows the address as a banner, the reader taps, and a phone with the app installed hands the link over to the app so the profile opens where the Follow button is. A phone without the app loads the web version, which shows the grid and then asks for a login before it goes much further. The code itself stores no account, no password and no counter.
Print it where a person is already looking at your work and has thirty seconds to spare.
Keep the quiet zone, four modules of clear space on every side. Cropping to the edge of the pattern kills more printed codes than any other mistake. For size, divide the reading distance by ten: a counter card read at 30 cm needs about 3 cm of code, a poster read from two metres needs about 20 cm, and under 2 cm nothing reliable happens at arm's length. Dark code, light background. Inverted codes fail on plenty of older readers. A logo in the middle is fine if error correction stays at Q or moves to H, and a heavily patterned photo behind the code is not fine at any level. Two limits worth saying out loud: change your username and every printed code pointing at the old one stops working, and a code made here counts nothing, so the follower jump you see in the app is the only feedback you will get.
Instagram already gives you a scannable code. Open your profile, find the QR option in the menu, and you get a coloured card that any Instagram camera, and most phone cameras, can read. It is free, it is instant, and for a profile it works. If you just want something on a phone screen for another person to scan across a table, use it and skip this page.
A generated code is the better choice in three situations. The first is print. The app hands you a screenshot sized image, while the generator above gives PNG at 200 to 800 px and, more to the point, SVG and EPS, which a printer can scale to a shop sign without the edges going soft. The file format question is covered in this comparison of PNG, SVG and EPS. The second is design. Your own two colours, a transparent background, an optional logo and a frame will sit inside a brand layout in a way that the app card will not. The third is the destination. The nametag points at your profile, full stop. If the thing worth scanning is one reel, a shop page, a link in bio page or a specific highlight, you need a code built from that URL, the same way you would for a Facebook page or a video link. Copy the address from a desktop browser, strip the tracking parameters after the question mark, and encode what is left.
The app code points at your profile and comes as a screen sized image in Instagram's own styling. A code made here can point at any Instagram address, carries your colours and logo, and downloads as SVG or EPS, which matters as soon as something is printed larger than a business card.
Yes. Any Instagram address works, including a single post, a reel, a shop page or a highlight. Copy it from a desktop browser rather than the app share sheet, because the share sheet often adds tracking parameters that make the code denser without changing where it goes.
The web version of the profile opens in the browser. They will see your picture, your bio and part of the grid, then hit a prompt to log in or sign up. Nothing is broken, but expect fewer people to go further if your audience is not already on the platform.
No. The old address stops resolving to your profile, and every printed copy of that code becomes a dead link. Pick the username before you print anything in quantity. If a change is likely, use an editable code so you can repoint it instead of reprinting.
Not with a code generated here. The address is baked into the pattern and nothing is reported back. Only the editable codes on this site count scans, with the countries they came from. Instagram's own insights will show profile visits but cannot tell you which of them came from a printed card.
SVG or EPS. Both are vector, so the same file works on a 3 cm sticker and a 3 m banner without the edges breaking up. PNG is for screens, email signatures and social posts. Ask the printer to keep the white margin around the code rather than trimming to the pattern.
