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

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  lt   25   puts  No problem here   else   puts  Sorry too long   end   https   ruby-doc org core-2 4 0 String html method-i-size

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