Mess with the traditional format, though, and you risk having your script dismissed as unprofessional. A truly conscientious reader will overlook these superficial matters and focus on the content. However, the more professional you look, the more they ll take your material seriously. Use a fixed-pitch, courier font. Proportional spaced fonts are slick, but the standard is courier.
Some readers actually dread proportional spacing, since it allows writers to cram more onto a page.
Don t center character cues. It may look cool, but it actually makes the script harder to read. Try to keep it under 120 pages, but no shorter than 100 pages. Longer screenplays used to be more acceptable. However, the trend is toward shorter, punchier scripts.
