2.39:1 aspect ratio
2.3900:1 · 2048×857 px · also called cinemascope, 2.4:1, widescreen film
2.39:1 is the theatrical scope ratio. Advertisers use it deliberately to signal 'film', usually in brand campaigns and site heroes where the letterbox is part of the aesthetic.
What 2.39:1 means
A 2.39:1 frame is 2.39 times wider than it is tall — multiply the width by 0.4184 to get the height. 1920×803 and 4096×1716 (DCI scope) are the standard sizes.
Where it is used
Brand films, YouTube brand spots, desktop hero video and pre-roll where a cinematic register is intentional.

Working with 2.39:1
- 01If the letterbox is intentional, bake it in; if not, deliver 16:9 and crop in the edit.
- 02Performance placements punish letterboxing — keep 2.39:1 for brand, not for direct response.
- 03Subtitle safely: at 803 px tall, captions need at least 36 px type.
