Quick answers

What is the safest single size to post everywhere? A 9:16 clip at 1080 x 1920 with important content kept inside the centre covers TikTok, Reels, Shorts, Stories, Facebook Reels, Snapchat and Pinterest.

What frame rate? 30fps is universally safe; 24fps for a filmic look; 60fps if the platform and content (fast motion) call for it.

What format? MP4 (H.264 video, AAC audio) plays everywhere. Keep bitrate high on upload - platforms compress on their end.

Do lengths change? Yes, platforms raise limits often. The numbers above are current for 2026; the aspect ratios and safe zones are stable.
