- What is the best video size for TikTok?
- TikTok’s recommended size is 1080 × 1920 pixels — a 9:16 vertical aspect ratio. That fills the screen edge to edge and is the format TikTok’s player and compression are optimised for. Export your master at 1080 × 1920 and you can post the same file to Reels and Shorts too.
- Is TikTok 9:16?
- Yes. The native TikTok aspect ratio is 9:16 (vertical), at 1080 × 1920 pixels. The app accepts other ratios, but 9:16 is the only one that fills the whole screen without letterboxing or cropping.
- Can you post a 1:1 or 16:9 video on TikTok?
- You can upload square (1:1) or landscape (16:9) video, but TikTok pads or crops it to fit the vertical player — leaving black bars or cutting off the edges. For anything you care about, shoot and export 9:16 / 1080 × 1920.
- How long can a TikTok video be?
- Recording in the app caps at 10 minutes; uploading from your camera roll on the web allows up to 60 minutes. Despite the longer limits, most high-performing TikToks are 15–34 seconds — long enough to land a hook and payoff, short enough to keep watch-through high.
- What is the TikTok safe zone?
- The safe zone is the part of the frame TikTok’s interface does not cover. The right-hand column (like, comment, share, profile) and the bottom block (caption, username, music) sit on top of your video — roughly the bottom ~22% and right ~13% on a 1080 × 1920 frame, and more once a Spark Ad CTA is added. Keep text, logos and faces in the centre, as the preview above shows.
- What file format and frame rate does TikTok use?
- Upload MP4 or MOV with H.264 video and AAC audio — the most compatible combination. 30 fps is standard; use 60 fps for fast motion or gameplay. Mobile uploads cap around 287 MB on iOS and 72 MB on Android, while web uploads allow up to 4 GB.
