How to Add a QR Code to a Flyer (Size, Placement, and a Scan Test That Saves Your Print Run)

A flyer with a QR code does something a flyer never used to do: it tells you whether anyone read it. Every scan is a click you can count, a sign-up you can attribute, a menu view you can time. That's why "qr code on flyer" is one of the most searched flyer questions of 2026, and also why so many printed codes never get scanned. They're too small, too faint, or sitting in a corner with no reason to point a phone at them.

This guide shows you how to add a QR code to a flyer properly: where the code should go, how big it needs to be, what it should link to, and the one test that catches a broken code before you've paid for 500 copies.

What to link before you make the code

The QR code is the door. Decide where it opens first, because it changes everything else. Good flyer destinations are a single page that loads fast on a phone: an event sign-up, a booking page, a menu, a directions link, a discount page, a WhatsApp chat, a review form, or a vCard so people can save your number.

Two rules. First, link to a page built for the flyer's one job, not your homepage. A scan that lands on a homepage with six menus loses most people. Second, consider a dynamic QR code if the link might change. A static code bakes the URL into the pattern for good; a dynamic code points to a short redirect you can update after printing. Dynamic codes usually cost a subscription, static ones are free forever.

If you want to track scans without paying for a dynamic code, add UTM parameters to the URL before you generate it. ?utm_source=flyer&utm_medium=print&utm_campaign=open-day shows the flyer's scans as their own line in Google Analytics, and Google's campaign URL builder writes the link for you.

How to add a QR code to a flyer in 6 steps

Step 1: Generate the code

There are two ways. Use a standalone generator and download a PNG or SVG, or use a design tool with a built-in QR element. Built in is easier because the code stays vector, recolors with the design, and updates if you change the URL. In Krumzi, for example, you add a QR code from the elements panel, paste the link, and pick the colors and error-correction level right there on the canvas. If you download from a generator instead, choose SVG or the largest PNG on offer so it doesn't pixelate when you scale it up.

Step 2: Set the error-correction level

Every QR code carries redundant data so it still scans when part of it is damaged, dirty or covered. The four levels come from the QR standard published by Denso Wave, the code's inventor: L recovers about 7% of damage, M about 15%, Q about 25%, and H about 30%, as described on qrcode.com. For print, use M or Q. Pick H only if you plan to put a logo in the middle of the code, since the logo counts as damage the code has to route around.

Step 3: Size it for the scanning distance

The rule of thumb is that a code's width should be at least one tenth of the distance people will scan it from. A flyer in someone's hand is scanned from about 20 to 25 centimeters, so a code 2 by 2 centimeters (roughly 0.8 inches) is the floor, and 2.5 to 3 centimeters (about 1 to 1.2 inches) is comfortable. On a poster pinned to a wall and read from a meter away, go to 10 centimeters. Never scale a code below 2 centimeters to make it fit; move something else instead.

Step 4: Get the contrast and quiet zone right

Phone cameras read the difference between dark modules and a light background. Dark code on a light, flat background is the safe default. You can color a code in your brand's dark shade (navy, deep green, charcoal) as long as it stays much darker than the background. What breaks scanning: inverted codes (light on dark), low-contrast pastel codes, codes over photos or gradients, and codes with a busy pattern behind them.

The quiet zone is the empty border around the code. The standard asks for a margin four modules wide (a module is one of the tiny squares), which in practice means a clean margin of about 3 to 4 millimeters on a 2.5 centimeter code. If your design tool lets you set a background block behind the code, use it and keep the block plain.

Step 5: Place it next to a reason

A code with no caption is a puzzle, and most people don't stop for puzzles. Put the code where the eye finishes reading, which on a portrait flyer is usually the bottom right or bottom center, and pair it with a short line that says what happens when they scan: "Scan to book your free class", "Scan for the menu", "Scan to RSVP". A tiny arrow or the word "scan" next to the code lifts scan rates more than any design flourish.

Keep the code away from folds, the trimmed edge, and staples. Leave at least 5 millimeters between the code and the paper edge, and if the flyer is going into a plastic sleeve on a noticeboard, remember glare: a matte finish scans better than gloss.

Step 6: Test on paper, not on screen

Screens are backlit and perfectly sharp, so a code that scans on your monitor tells you almost nothing. Export the flyer as a PDF, print one copy on the printer you actually have, and scan it with at least two phones (one iPhone, one Android) using the default camera app. Then test it in worse conditions: dim light, from an angle, held a bit far away. If it scans in all of those, it will scan on the street. Only then send the full run to print.

One more check: open the link on the phone that scanned it. A code that scans but lands on a desktop-only page, a 404, or a page that asks for a login has failed just as badly as one that doesn't scan.
