LEN, LENB functions

LEN returns the number of characters in a text string.

LENB returns the number of bytes used to represent the characters in a text string.

 Important   LEN is intended for use with languages that use the single-byte character set (SBCS), whereas LENB is intended for use with languages that use the double-byte character set (DBCS). The default language setting on your computer affects the return value in the following way:

  • LEN always counts each character, whether single-byte or double-byte, as 1, no matter what the default language setting is.
  • LENB counts each double-byte character as 2 when you have enabled the editing of a language that supports DBCS and then set it as the default language. Otherwise, LENB counts each character as 1.

The languages that support DBCS include Japanese, Chinese (Simplified), Chinese (Traditional), and Korean.

Formula Description (Result)
=LEN(A2) Length of the first string (11)
=LEN(A3) Length of the second string (0)
=LEN(A4) Length of the third string, which includes 5 spaces (8)

Example 2: LENB (with your computer set to a default language that supports DBCS)

In the following example:

  • LENB returns 6, because each character is counted as 2.
  • LEN returns 3, because each character is counted as 1. LEN returns 3 no matter what the default language setting is on your computer.

=LENB("Tokyo to Shibuya Tokyo to Shibuya Tokyo to Shibuya ") equals 6

=LEN("Tokyo to Shibuya Tokyo to Shibuya Tokyo to Shibuya ") equals 3
