Page Eighths Explained: How to Measure Scene Length in a Screenplay

Quick answer: Productions measure scene length in eighths of a page. A standard screenplay page is divided into eight equal parts of about one inch each, so a scene that fills three inches is 3/8 of a page, and a scene running a page and a half is written 1 4/8 (never simplified to 1 1/2). No scene is shorter than 1/8. Eighths are added up to plan how much script to shoot each day.

Key takeaways

• One page = 8/8; each eighth is roughly one inch of the page's text area.

• Write eighths unsimplified: 4/8, not 1/2; 1 6/8, not 1 3/4.

• Minimum per scene: 1/8, even for a one-line scene.

• Eighths power the stripboard, breakdown sheets and daily page targets.

Why eighths and not minutes?

Because standard format makes page length a reliable measure — roughly a minute per page — and eighths are fine enough to describe short scenes but simple to add up. Keeping fractions in eighths, rather than simplifying, makes totals easy to sum on a stripboard without converting fractions.

How do you count eighths?

1. Visualise or draw lines dividing the page's text area into eight equal horizontal bands (about an inch each on US Letter).

2. For each scene, count how many bands it occupies, starting at its scene heading and ending at the last line before the next heading.

3. Round partial bands: if a scene touches part of a band, most ADs count it as a full eighth; if two scenes share a band, assign it to the one using more of it.

4. For scenes that cross pages, add the eighths on each page: 5/8 on page 12 + 3/8 on page 13 = 1 (8/8).

Worked examples

• A scene from the top of a page to the middle: 4/8.

• A full page plus three inches on the next page: 1 3/8.

• A one-line insert shot: 1/8.

• Two pages and a half: 2 4/8.

Are eighths accurate for timing?

They are a starting estimate. A 1/8 action line such as "The two armies collide" may take a full shoot day, while 2 pages of quick dialogue may take an hour. That is why breakdown sheets also include estimated shoot time and complexity notes (stunts, VFX, extras). Combine eighths with shot lists to estimate a day properly — see how to make a shot list.

How are eighths used in scheduling?

Each strip on the stripboard shows the scene's eighths, and the day's total appears at each day break, so the 1st AD can see at a glance whether a day is overloaded (for example 9 2/8 pages on an indie schedule) and rebalance. Producers also use total eighths per location to estimate how many days a location must be rented.

Count eighths automatically

Counting eighths by hand across a 120-page script takes hours and changes with every revision. Kathe Kaara calculates page eighths for every scene from your formatted screenplay, shows them on breakdown sheets, scene reports and strips, and recalculates whenever you edit.

Frequently asked questions

Why write 4/8 instead of 1/2?

So that every value uses the same denominator, making stripboard totals quick to add.

Can a scene be 0/8?

No. The minimum is 1/8 for any scene with a heading.

Do eighths change with A4 paper?

The method is the same — divide the text area into eight — but page breaks may shift slightly. Keep one paper size for the whole production.

Who measures eighths?

Traditionally the 1st AD or production manager during the breakdown; software now does it automatically.
