THE PRACTICAL QR HANDBOOK
QR codes for flyers and posters
Turn a printed call to action into an easy mobile visit.
Start with the right destination
Pick one action: book a place, see a timetable, or read more. State that action next to the code and make the destination match the promise. People should not need to search a homepage for what the poster offered.
Design for actual viewing distance. A flyer held in the hand needs a different symbol size from a poster across a corridor. Avoid curved surfaces, glossy reflections, patterned backgrounds, and folds through the code. Test the physical poster under the lighting where it will be displayed.
Match the sign to its surroundings
A poster is often read in motion. Give the code a short, concrete caption and enough separation from surrounding artwork that the camera can find it. If the poster sits behind glass, inspect reflections at the angles a passerby will use. If it is outdoors, account for rain, fading, grime, and the possibility that the lower edge becomes obscured. Put essential event dates or telephone details directly on the poster too.
For a flyer, keep the code away from folds and trim boundaries. Send the printer a vector file where possible and check that the exported print PDF has not rasterized it at a very low resolution. Do not judge a proof only from a magnified preview. Hold a physical copy at a comfortable distance and ask someone else to scan it without instructions.
If you want to compare distribution locations, create separate codes with clear labels rather than collecting personal information about readers. Counts indicate requests to the redirect and may include repeated scans; they are not a reliable count of unique people or completed purchases. Check campaign outcomes on the destination using methods appropriate to your privacy commitments. Remove outdated signs and keep surviving links useful after a promotion ends.
Build and test it step by step
- Decide what a person should accomplish after scanning. Write a short call to action in ordinary language, then prepare the destination before generating the code.
- Open the destination on a phone using mobile data. Check loading speed, text size, navigation, and whether anything requires an unexpected login. Fix those issues before printing.
- For a web destination that may change, create a Forever QR account and save the secret manage link somewhere safe. Create a code with a descriptive label so you can identify it later.
- Download the SVG for a print designer or the high-resolution PNG for a simple document. Keep the original file with your artwork and record where you intend to distribute it.
- Print a proof at its final size. Scan it using several phones, at realistic distances, under both good and imperfect light. Follow the entire journey rather than stopping when the camera recognizes the symbol.
Make the printed code easy to scan
Leave a clear border around the symbol. QR readers use this quiet zone to separate the code from surrounding artwork. Keep at least four modules of empty space on every side. Do not crop that space when placing the image into a design tool. A dark foreground on a plain light background is the most dependable starting point. Decorative colors can work, but a color combination that looks attractive on a screen may lose contrast on paper.
Size depends on viewing distance, payload density, print quality, and the camera. For handheld material, start around 25–30 mm wide and test a physical proof. Increase the size for distant signs. Avoid putting a fold, staple, logo, or reflective coating through the symbol. When printing on textured stock, ask the printer for a sample. A successful scan of a large preview on your laptop does not prove that a small printed version will work.
Maintain the experience after printing
Keep an inventory of the places where your code appears and review the destination periodically. When information changes, update the destination or its content and scan an old printed copy again. Give each campaign a clear label rather than relying on memory. Keep a readable web address and a contact method nearby so people have an alternative if scanning is difficult.
Save your secret manage link in a password manager or download the key file and store it securely. Anyone with that key can manage the account. Forever QR cannot email a replacement because accounts do not require an email address. Losing access does not stop existing codes from redirecting, but it prevents you from editing their destinations.
Frequently asked questions
Can I change the destination after printing?
A dynamic web redirect can be edited through its account. A static symbol cannot be rewritten after printing. Check what the symbol actually contains before choosing a workflow.
Will the code work forever?
Forever QR keeps codes redirecting for as long as the service exists, with exceptions for abuse or illegal content. If the service shuts down, we commit to at least 12 months notice and an export of destinations. The linked website must also remain available.
What should I check before a large print run?
Verify the destination, scan a physical proof, check contrast and clear space, and save your account key. Ask someone unfamiliar with the project to try the complete flow. Their feedback often reveals unclear instructions that the designer has stopped noticing.
