Frequently asked questions
What uses a 2:1 aspect ratio?
Modern streaming productions (notably Netflix originals), panorama crops, and social cards such as link previews. It is a compromise between widescreen video and ultrawide cinema.
Is 2:1 the same as 18:9?
Yes, mathematically identical — 18:9 reduces to 2:1. Phone makers market 18:9 because it echoes the familiar 16:9 naming.
How do I crop a photo to 2:1?
Fix either dimension and let the calculator solve the other: for a 2000px-wide crop, the height is 1000px. Then crop with those values.
