How to write a documentary logline (with examples)

The first line a funder reads, and the one that decides whether they read the next. Here’s how to make one sentence pull its weight.

Short answer

A documentary logline is one or two sentences that capture who the film follows, what’s at stake, and what makes it singular — written to make someone want to see it. A reliable shape: [a specific subject] must [face a struggle] as [stakes/obstacle], revealing [a larger meaning]. Lead with the human and the tension, not the topic; if a reader can’t repeat it back, it’s not done.

What a logline has to do

Its only job is to make the reader want the next paragraph. In a funding application — or a festival form, or an email to a broadcaster — the logline is the hook that earns attention for everything after it. It conveys subject, stakes and singularity in a breath, without plot mechanics.

A formula that works

You don’t have to follow it rigidly, but it’s a strong default:

[Specific subject] must [goal or struggle] as [obstacle/stakes] — revealing [larger meaning].

The key word is specific. “A community fights climate change” is a topic, not a logline. “As the sea swallows their island, three families decide what’s worth saving” is a film.

You’ve got the proposal. Now find the funds worth sending it to.

The Documentary Funding Vault lists 150+ verified funding opportunities filtered to what you’re actually eligible for — region, stage, format and focus — so your proposal lands where it can win.

Examples

Each names a person, a tension, and a hint of larger meaning — in one sentence.

Frequently asked questions

How long should a documentary logline be?

One sentence is ideal; two at most. If it runs longer, you’re writing a synopsis. The test: can someone read it once and repeat the gist back?

What’s the difference between a logline and a synopsis?

The logline is one or two sentences designed to hook; the synopsis is a paragraph that lays out the story, stakes and access. The logline sells the read; the synopsis delivers it.
