Preparing tool…
Reading and generation stay in your browser. Check the result before you share, print, or open a link.
Capacity depends on the characters you use. Digits fit more than mixed text. This uses the same QR engine as the generators, so the numbers match what will actually encode.
High correction holds less data and leaves room for a logo or a damaged print. Low correction holds more and is less forgiving.
How to use this tool
- Choose a correction level.
- Optionally paste a sample.
- Read the capacity for digits, upper case, and mixed text.
Practical guidance
High correction holds less data and leaves room for a logo or a damaged print. Low correction holds more and is less forgiving.
Checks before you use the output
If your real text is near the limit, generate it and scan a proof. Do not assume the maximum will print well at a small size.
Questions and answers
Why are there three numbers?
QR switches mode. Digits, upper case, and mixed text are stored differently.
Does a logo reduce capacity?
The data limit stays the same, but you should use High correction, which holds less.
Is this the ISO table?
It is measured from Kayefi’s QR engine, which follows the standard encoder.
