ASPECT RATIO TOOL
Finding the right resolution for a specific aspect ratio can be challenging. To simplify this, we’ve created a tool to list resolutions you can use when exporting content at various aspect ratios and frame sizes. If you notice any errors or have suggestions for updates, please let us know.

Frame sizes are rounded down to the nearest even number to ensure compatibility with video encoding standards. This prevents issues like partial pixels or problems with field encoding.
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.”
​We base our 2.39:1 calculations in this document on the cinema-standard Scope ratio (2048/858). This keeps things practical, especially if you’re targeting cinematic delivery.
