If you are using an earlier version (Word 2003 or earlier), this tip may not work for you. For a version of this tip written specifically for earlier versions of Word, click here:
A = Len(MyString)
B = Len("This is a test")
The first line returns the length of the characters in the variable MyString. The second returns the number of characters between the quote marks (in this case, 14—remember that spaces count as characters).
If you want to determine the length of a selection, you follow a bit different approach:
C = Len(Selection)
This line returns the length of the current text selection in the document. Remember when calculating the length of a selection that paragraph marks (hard returns) count as two characters. That is because they are each really a carriage return followed by a line feed, even though all other macro commands treat them as a single character.

The testing I've done in M365 Word suggests a paragraph mark is counted as only one character using the Len function (and that an end-of-cell marker in a table is counted as two characters).

Thanks, Allen. The answer to the old question, "How long is a piece of string" is not that easy;-}}
