Last updated: 2026-10-09

A version 5 QR code is 37 modules per side, or 45 modules including the 4-module quiet zone. At error correction M it holds up to 122 alphanumeric characters or 84 bytes.

Maximum characters by error correction level

	L	M	Q	H
Numeric	255	202	144	106
Alphanumeric	154	122	87	64
Byte	106	84	60	44
Kanji	65	52	37	27

The byte row counts bytes. Japanese or Chinese text in UTF-8 takes 3 bytes per character. The kanji row counts characters encoded in kanji mode (Shift_JIS). This site's generator encodes text in byte mode (UTF-8), so treat the kanji row as the limit set by the standard.
