blank lines regular expression	Can't Post

i have below lines of code in my tool (cloc--> code count tool) with which it recognizes blank lines

filter remove_matches ^\s*//

but, i want to tell the tool that if a any line contains less than 2 characters then it should consider that line as Blank line. How can modify the above regular expression to consider a line as blank line if it contains less than 2 characters.
