I often have to convert between different resolutions of videos and images and always forget the pixel dimensions that correspond to a 16:9 format. So here is a cheat-sheet:
- **2160p: **3840×2160
- **1440p: **2560×1440
- **1080p: **1920×1080
- **720p: **1280×720
- 540p: 960x540
- **480p: **854×480
- **360p: **640×360
- **240p: **426×240
- 120p: 213x120
I also came across this complete list of true 16:9 resolution combinations, but the ones above suffice for my usage. Happy converting!
