Film scripts are measured in eighths of a page. A scene occupying a third of a page is recorded as 3/8. A scene running two and a half pages is 2 4/8. The convention is universal in scheduling, and every page count you will ever see on a stripboard, a call sheet or a production report uses it.
The reason is physical. A standard screenplay page has a one inch margin at top and bottom, leaving roughly eight inches of text. Divide that into eight one-inch bands and you have a unit you can measure with a ruler, which is exactly how it was done for decades: a strip of card marked in eight divisions, held against the page.
Why eighths and not something sensible
Because an inch is a thing you can see.
Halves are too coarse; a great many scenes are less than half a page and they are not all the same size. Sixteenths are more precision than the underlying estimate deserves, since page length is only a proxy for shooting time anyway.
Eighths sit at the point where the unit is fine enough to be useful and coarse enough to be honest. It also happens to be roughly the smallest scene anyone bothers to schedule separately.
An eighth is about six seconds of screen time at the conventional page-a-minute rate, with all the caveats about why that rate lies.
How to count them
A full page is 8/8, written as 1 page rather than 8/8.
A scene that starts and ends on the same page: measure from the top of the slugline to the last line of the scene, and round to the nearest eighth. If it occupies about a third of the vertical space, it is 3/8.
A scene spanning pages: count the eighths on each page and add. A scene starting 5/8 down page 12 and ending 2/8 into page 13 is 3/8 plus 2/8, which is 5/8.
Any scene, however short, is at least 1/8. A two-line scene consisting of a slugline and one action line is 1/8. There is no such thing as a zero-eighths scene, because there is no such thing as a scene that takes no time to shoot. This is important and it is the rule most often broken by people counting quickly.
Round sensibly. You are estimating. A scene that measures 2.6 eighths is 3/8. Nobody will audit you, and precision beyond the eighth is false confidence.
Counting the dialogue rather than the page space. Dialogue is indented, so a page of dialogue contains far fewer words than a page of action, but it occupies the same eight inches and takes the same eight eighths. The unit measures paper, not content. This is also why the format is fixed: as soon as someone changes the margins or the font, the ruler stops working and every downstream number is wrong.
Notation
Written with the whole pages first and the eighths as a fraction:
3/8: three eighths of a page1 2/8: one and a quarter pages2 7/8: nearly three pages
Eighths are conventionally not reduced. It is 2/8 and 4/8, not 1/4 and 1/2. This looks wrong to anyone with a mathematics background and it is deliberate: keeping the denominator constant makes columns of page counts trivially addable by eye, which was the entire point when this was done with a pencil.
Adding them works as you would expect, carrying at eight:
3/8 + 5/8 = 8/8 = 1 page 1 6/8 + 2 4/8 = 3 10/8 = 4 2/8
What the numbers are for
Three things.
Totalling the film. The sum of all scene eighths should approximate your page count. If it does not, something is miscounted or a scene is missing.
Loading a shooting day. This is the real use. Each day on a schedule carries a total page count, and that number is the primary early warning that a day is overloaded.
Tracking progress. Daily production reports record pages scheduled against pages completed. A production that is consistently shooting fewer pages than scheduled is falling behind in a measurable way, and the eighth is the unit that measurement happens in.
How many pages is a day?
The number that people want and that has no honest universal answer. As rough anchors:
- Studio feature, well resourced: 2 to 3 pages a day is common.
- Independent feature: 4 to 6 pages a day, and it is a hard 6.
- Low budget, tight schedule: 8 to 10 pages a day happens and it hurts.
- Television drama: varies enormously by format, often 5 to 8.
- Multi-camera sitcom or soap: far higher, because the format is built for it.
These are averages hiding enormous variance. A five-page dialogue scene between two people in one room, shot with two cameras, may take half a day. A 3/8 scene involving a car, rain and a stunt may take all day and then some.
Which is why page count alone is never sufficient, and why estimating how long a scene actually takes is treated separately.
Eighths measure the script. They do not measure the difficulty. A page of two people talking and a page of a fight are the same length and not remotely the same day.
Where the count misleads
Action. The classic case. "The chase continues through the market" might be 2/8 on the page and a day and a half on the floor. Any script with substantial action needs those scenes estimated by time rather than by pages, and the estimate written into the notes.
Silence and long takes. A short scene shot as one carefully choreographed take can eat a morning.
Company moves. Not in the page count at all. Moving the unit between locations costs hours and appears nowhere in an eighths total, which is why a day with three moves and five pages is worse than a day with no moves and eight.
Number of setups. A single page covered from nine angles takes far longer than a single page in one wide. Some schedulers track setups alongside pages for exactly this reason.
The working practice is to use eighths as the default load measure, and to override it with a time estimate wherever you know the page count is lying.
Counting a whole script
Practically, for a feature:
- Go scene by scene in order, recording eighths on each breakdown sheet.
- Total them and compare against the script's page count. They should be within a page or two.
- Flag every scene where you believe the page count understates the work, and write a time estimate in the notes.
- Carry the counts into the stripboard, where they become the number on each strip.
Modern scheduling software calculates all of this on import and recalculates when pages change, which removes the arithmetic but not the judgment. The flags in step 3 are still yours to make, and they are the part that matters.

Eighths counted for you
Film Logic measures every scene in eighths as soon as the script is imported, keeps the count current as pages change, and totals them per day on the schedule so you can see when a day is overloaded before you shoot it.
