Aspect ratio and resolution
All three platforms are vertical 9:16. Export at 1080×1920 for crisp quality; the platforms downscale as needed. Anything square or landscape gets letterboxed and looks amateur in the feed.
DigitalIncomeRoute exports true 1080×1920 MP4s, so one render works across TikTok, Reels and Shorts.
Length and safe zones
Keep it 15–40 seconds for the best completion rate. Keep important text away from the very top and bottom, where the UI (username, caption, buttons) sits.
File format
Export H.264 MP4 with AAC audio — the universally accepted combination. Upload the raw file natively rather than sharing a link to it.
Frequently asked questions
What is the exact size?
1080×1920 pixels, 9:16 aspect ratio, is ideal for all three platforms.
What frame rate?
30fps is standard and safe; 60fps is fine for fast motion.
MP4 or MOV?
MP4 (H.264 video, AAC audio) is the most compatible choice.
