TikTok video dimensions in 2026: 1080×1920 (9:16) native. Full list of supported aspects, pixel sizes, and common upload mistakes.
TikTok video dimensions: 1080×1920 (9:16 aspect ratio).
The recommended TikTok video dimensions in 2026 are 1080×1920 in a 9:16 aspect ratio. This is the resolution the feed renders at natively — uploading at a smaller size triggers an upscale and visible softness; uploading larger gets downscaled, costing you sharp text.
TikTok supports 9:16 (1080×1920), 1:1 (1080×1080), 16:9 (1920×1080). The platform's encoder re-transcodes anything you upload, so shipping at the native ratio is the single biggest lever for retaining quality. Bitrate matters less than ratio — match the ratio and the algorithm doesn't have to letterbox or center-crop.
Common mistakes creators make on TikTok: (1) exporting at 1280×720 instead of full HD — works, but you lose half the pixel density on retina phones. (2) Letterboxing a 16:9 clip into a 9:16 frame with black bars — the algorithm reads the dead zones as low-quality content and suppresses reach. (3) Burning in captions in the wrong safe-zone for TikTok — UI chrome differs per platform, so a caption that's clear on TikTok can be obscured by TikTok's overlay.
If you're repurposing from another platform, convert the aspect ratio first. A common conversion path is reframing a 16:9 long-form clip into a 9:16 short by using smart-crop (subject tracking) rather than naive center-crop. Note: 10 min upload widely cited; 60 min rolling out per creator tier.

| Snapchat Spotlight | 1080×1920 | video-short |
1080×1920 (9:16) is the native resolution. TikTok accepts 9:16 (1080×1920), 1:1 (1080×1080), 16:9 (1920×1080) but renders best at the primary ratio.
Yes — TikTok will accept higher-resolution uploads, but the player tops out at 1080×1920 on most devices, so you're paying upload bandwidth for pixels the viewer never sees.
TikTok either letterboxes (black bars) or center-crops. Both reduce reach because the algorithm reads the dead space or the cut-off subject as low-quality content.
No. TikTok doesn't support re-uploading a different version under the same post. Delete and re-publish if you must change ratio.
9:16 is the native frame. If you're cross-posting, render the master at 9:16 and convert outward — converting toward 9:16 from another ratio always loses pixels.
