How long should a theatrical window be before a film goes to streaming?

The market has already answered and it answered against the 2021 consensus: windows are lengthening. Universal moves to 45 days and seven weekends on January 1, 2027, from 17 guaranteed days in 2020. But the decision is being made on a market 23% smaller than 2019, which changes what a window is worth rather than how long it should be.

The evidence

Where the majors actually sit.

Universal: 31 days and five weekends now, 45 days and seven weekends from January 1, 2027. Paramount: 45 days and seven weekends. Amazon MGM: 45 days. A24: 31 days or fewer. Focus Features stays at three weekends because Universal says PVOD drives its smaller titles.

Even Netflix now runs one.

Narnia goes wide on February 12, 2027 with a Netflix debut on April 2 — roughly 49 days, and described as the first Netflix title with a full exclusive theatrical run.

The base underneath the decision shrank.

2025 domestic box office was $8.72bn against $11.26bn in 2019 — down 23%. Global 2025 was $33.55bn against $42.3bn. First-half 2026 global was $16.6bn, up 2% year over year but 17% below the 2017–19 average.

Concentration did not rise. Dependency did.

The top ten domestic titles took 41.3% of the market in 2019 and 40.6% in 2025 — essentially flat, on a market a quarter smaller. Each top-ten slot is worth less and the base beneath it is thinner.

The causal claim underneath window policy is unevidenced.

No rigorous public study shows a theatrical run causally lifts streaming performance or library value. The best available analysis disclaims its own conclusion.

What would have to be true for this to be wrong

If your distribution economics run on premium video on demand rather than on admissions — as Universal says Focus Features' do — a short window is correct and the majors' direction is somebody else's trade. The length follows from where your revenue actually lands, not from where the industry is drifting.
