How big does a qr code need to be?

QR codes are similar to barcodes, but they can store more information and can be read by smartphones and other devices. These codes can be used for a variety of purposes, including marketing and advertising, product tracking, and even contactless payment. Thanks to their versatility and ease of use, QR codes have become increasingly popular in a world that is increasingly reliant on digital communication. But suppose you want to generate a QR code for your business. You may want to know the average size of the QR code.

This guide will help you know more about its size.

Distance to size ratio

Most people are not familiar with the size of QR codes. You should know that QR codes were designed for a specific distance-to-size ratio. The optimal distance between the QR code and scanner is 10 times the width of the code. That means if you have a QR code that is 3 centimeters wide, the ideal scanning distance would be 30 centimeters. This distance can vary slightly depending on the size and quality of the QR code, but it's a good rule of thumb to follow when scanning QR codes.

Minimum size of QR codes

While there is no set standard for QR code size, your QR code should have a minimum size of 0.8 x 0.8” or 2 x 2 cm. However, you'll find QR codes that are smaller than this, and many smartphones are able to scan codes that are just a few millimeters in size. This makes them perfect for use in print advertisements, flyers, and other marketing materials. While extremely small QR codes may be difficult to scan, they can still be used for a variety of purposes, such as sharing contact information or links to websites.

When creating a QR code, it's important to consider the amount of data that will be encoded. If too much data is encoded, it can make the QR code difficult to read, especially at lower resolutions. In general, it's best to encode no more than 1-2kb of data in a QR code. This will ensure that the code can be read by most devices and scanners even if it has the minimum size.

QR codes have become an increasingly popular way for businesses to connect with customers through digital marketing. By embedding a QR code in print ads, commercials, or other marketing materials, businesses can direct customers to a website, video, or coupon.
