How to Use This Calculator
  1. Select a QR code version (1-10). Higher versions create larger symbols that hold more data.
  2. Choose an error correction level (L, M, Q, or H). Higher correction recovers more damage but reduces data capacity.
  3. View the maximum data bytes available in byte mode and the total module count.
  4. Use this to determine if your data fits in a given QR version before generating codes.
