Introduction
The QR Code Size Calculator is a useful tool for individuals looking to generate QR codes with optimal readability and scanning performance. By inputting the size of the data (in characters) that you plan to encode into the QR code, this calculator provides a quick recommendation for the ideal QR code size in pixels.
Formula
The calculator employs a straightforward formula that takes into consideration the number of characters in the data. It assumes a fixed size requirement per character and calculates the QR code size accordingly, ensuring a balance between compactness and readability.
How to Use
- Enter the size of the data (in characters) you want to encode into the QR code.
- Click the “Calculate” button.
- View the recommended QR code size in pixels in the result.
Example
For example, if the size of the data to be encoded is 25 characters, input this value, click “Calculate,” and the calculator will provide the recommended QR code size in pixels.
