Use the width, columns or cols method to detect terminal screen width:

TTY::Screen.width    # => 280
TTY::Screen.columns  # => 280
TTY::Screen.cols     # => 280

Use the height, lines or rows method to detect terminal screen height:

TTY::Screen.height  # => 51
TTY::Screen.lines   # => 51
TTY::Screen.rows    # => 51
