You could take any of the answers above that use the string.length method and replace it with string.size.

They both work the same way.

if string.size <= 25
  puts "No problem here!"
else
  puts "Sorry too long!"
end

I think you could just use the String length method     http   ruby-doc org core-1 9 3 String html method-i-length  Example   text    The quick brown fox jumps over the lazy dog   puts text length  gt  25    Too many characters     Accepted

Ruby provides a built-in function for checking the length of a string  Say it s called s   if s length  lt   25     We re OK else     Too long end

Instead of using a regular expression  just check if string length   25
