The size of a TikTok video, and the parts of the screen to keep clear.
Why vertical
TikTok is watched full screen on a phone held upright. A 9:16 video fills that screen; a square or landscape video leaves empty space around it.
What covers a TikTok
The username, caption and sound sit along the bottom of the screen, the buttons run up the right side, and the feed tabs sit at the top. Keep anything important away from those areas, with the biggest margin at the bottom.
Making TikTok videos in Melon Cut Design
The Social media video format makes 1080 × 1920 videos about 10 seconds long by default, with hook-first pacing. Make one from a prompt or from your photos, then download it and post it yourself - Melon Cut does not post to TikTok for you.
