    Standard "green bar" page sizes included portrait-format pages of
    8½ × 11 inches, usually printed at 80 columns by 66 lines (at 6
    lines per inch) or 88 lines (at 8 LPI), and landscape-format pages
    of 14 × 11 inches, usually printed at 132 columns by 66 or 88 lines.
    Also common were landscape-format pages of 14 × 8½ inches, allowing
    for 132 columns by 66 lines (at 8 LPI) on a more compact page.
