Complete Tables of QR Code Character Limits

Table of Contents

This is an extra post to accompany “Tips on Creating the Smallest Possible QR Codes” and just contains complete tables of standard QR code data capacities in the numeric, alphanumeric, and binary/byte input modes.

The binary/byte input mode is the most general and can encode arbitrary data.
The alphanumeric input mode can only encode 0–9, (uppercase) A–Z, space, and $%*+-./:.
The numeric input mode can only encode the digits 0-9.

Here are the total character limits, with more details available in the following sections.

Encoding Preference	Binary/Byte	Alphanumeric	Numeric
Optimizing for size first	2953	4296	7089
At least M (medium), ~15% error correction	2331	3391	5596
At least Q (quartile), ~25% error correction	1663	2420	3993
Always H (high), ~30% error correction	1273	1852	3057

Optimizing for size first
#

Note that when preferring small sizes, only low error correction is optimal beyond version 5. At that point, it is always better to drop down to a smaller version if you had a higher error correction level.
