In the list below, the maximum characters (symbols) a QR code can hold are based on QR code version 40 with error correction capacity at level L.  QR codes use the Reed–Solomon error correction algorithm.

  • Maximum characters for QR code having only Numeric data: 7,089 characters
  • Maximum characters for QR code having Alphanumeric data:  4,296 characters
  • Maximum characters for QR code having 8-bit Binary data: 2,953 bytes
  • Maximum characters for QR code having Kanji/Kana: 1,817 characters

  • Version 13, 69×69, 259-619 alphanumeric chars
  • Version 31, 141×141, 1150-2677 alphanumeric chars

QR code error correction capacity (approximate)

  • QR Code Level L can error correct a QR code that is 7% unreadable
  • QR Code Level M can error correct a QR code that is 15% unreadable
  • QR Code Level Q can error correct a QR code that is 25% unreadable
  • QR Code Level H can error correct a QR code that is 30% unreadable
