Character count of each line

Hi,

I have a file with more than 1000 lines. Most of the lines have 16 characters. I want to find out lines that have less than 14 characters (usually 12 or 13).
wc -l gives me the line count and wc -c gives me the total characters in a file. I could not get the total characters for each line.

Appreciate your help

To print all lines with length not equal to 16:

awk 'length($0) != 16' filename
