A TikTok post fills the whole screen at 1080 by 1920, a 9:16 ratio, with your caption overlaid at the bottom left and the action rail down the right. Only about the first 100 characters show before the caption collapses behind a more link, so the opening line carries the post. PostDecks renders that frame so you can see it before you publish.
| Frame size | 1080 × 1920 (9:16) |
|---|---|
| Aspect ratio | 9:16 vertical, full screen |
| Caption limit | 4,000 characters |
| Caption cut-off | About 100 characters, then a more link |
| Photo carousel | Up to 35 images |
| Safe area | Keep text and logos out of the top 12.5%, the bottom 34.4% and 11.1% at each side, plus the lower right corner where the buttons stand |
Check that your caption's first line stands on its own and that nothing important sits under the rail or the sound row. Press Safe zones on the preview to shade the parts TikTok's own ad template keeps text and logos out of. Export a PNG mockup or a PDF for sign-off when it reads right. Everything runs in your browser, so your images are never uploaded.
