To recap, don’t worry about the paper size.
This by itself is a 10% difference per page! Also, don’t forget to take note that you are allowed to use double or even triple spaces between lines, or break up your page breaks for better readability. For a 100 page script, it would approximate 100 minutes in US Letter, and 102 minutes in A4. If one page equals one minute (60 seconds) in US Letter, it would mean 61 seconds on A4. That’s an approximate difference of 2% between the two. For A4 paper, this means 55-64 lines, and for US Letter paper, this means a maximum of 51-60 lines. I’ve been using it for A4, since that’s the only kind of paper I can buy in India.Ĭourier 12-point should give you 4.23mm (0.166″) per line.
The screenplay format is designed for US letter, and not for A4. If it is going to the US, then it will be printed on US Letter. If you’re sending a web PDF document, then consider where it will be printed. You might be wondering if there are any practical ramifications of using A4 over the standard US Letter format. How is A4 different from US Letter for screenplays?
