A Note on Scope Aspect Ratios

You’ll often hear people mention 2.35:1, 2.39:1, and 2.40:1, but today, they’re usually referring to 2.39:1

- 2.35:1 was common in films before 1970.
- 2.40:1 is just 2.39:1 rounded up incorrectly.
- 2.39:1 is the modern standard, often tied to Digital Cinema Scope (calculated as 2048/858 = 2.39).

Sometimes, though, 2.40:1 is specifically required - like for Blu-Ray scope content (1920 x 800). Because of this, we’ve included all three variants.

Our Advice: For anything between 2.35:1 and 2.44:1, check with your delivery destination (e.g., Blu-Ray at 1920 x 800 and 2K DCI Scope at 2048 x 858) and use their exact specs. It’s better to match their expectations than to argue about what’s “correct.”
