What aspect ratio is best for TikTok?

9:16 vertical for most videos and photo posts. TikTok says vertical and horizontal are both fine; the problem is blurred or black bars that shrink the picture.

What is the frame size on TikTok?

1080 × 1920 pixels for a full-screen vertical video. Horizontal videos are 1920 × 1080.

How do I change the aspect ratio on TikTok?

Crop it before or while you edit. TikTok's photo flow lets you crop each photo, and TikTok suggests cropping wide footage in so the subject fills a 9:16 frame.

What size are TikTok photo posts?

TikTok does not publish one. 1080 × 1920 (9:16) is the common choice because it fills the screen. Through the API, photos go up to 1080p as JPEG or WebP.

How many photos can a TikTok carousel have?

Up to 35, in the app and through TikTok's API, so schedulers can post all 35 too.

What is the TikTok profile picture size?

TikTok only sets a minimum: photos must be at least 20 × 20 pixels. 200 × 200 is the commonly used size, and it shows as a circle.

Can I post horizontal videos on TikTok?

Yes. Viewers can tap Full screen to watch them across the screen. Fill the frame instead of adding bars to make them vertical.

What resolution should TikTok videos be?

1080p or higher. That is what the Creator Rewards Program asks for. TikTok's API accepts 360 to 4,096 px on each side at 23 to 60 fps.

Can I upload a custom cover through a scheduler?

No. TikTok's API takes a frame from the video, picked by its time, not a separate image. In the app you also pick a frame.

Video 9:16

Use it for: Most videos
In the app: Fills the screen
Via schedulers: Yes, 360 to 4,096 px a side
Note: Creator Rewards wants 1080p or more

The short answer

Use 1080 × 1920 (9:16). It fills the screen in the app and through every scheduler.

TikTok's own guide says to "crop to a full-screen 9:16 vertical frame", which is 1080 × 1920 pixels. Horizontal video is fine too, because viewers can tap Full screen. TikTok's warning is about blurred or black bars that shrink your subject into a small box.

Schedulers, OmniSocials included, post through TikTok's Content Posting API. It takes videos of 360 to 4,096 px a side and photos as JPEG or WebP up to 1080p and 20 MB, with up to 35 photos per post. TikTok's Creator Rewards Program asks for 1080p or higher.

Video: 1080 × 1920; 9:16, in the app and via the API
Photo post: Up to 35; JPEG or WebP, up to 1080p via the API
Profile photo: 20 × 20; TikTok's minimum; 200 × 200 is common

App vs schedulers

What the app allows, and what a scheduled post must fit. Schedulers publish through TikTok's API.

TikTok image and video limits in the TikTok app compared with TikTok's Content Posting API used by scheduling tools
Limit	TikTok app	Schedulers (the API)
Photos per post	Up to 35	Up to 35
Photo file	Not published	JPEG or WebP, up to 20 MB each
Photo size	Not published	Up to 1080p
Video size	Not published	360 to 4,096 px a side
Video file	Not published	MP4, WebM or MOV, up to 4 GB
Frame rate	Not published	23 to 60 fps
Cover	Any frame you pick	A frame, set by its time in the video

Every scheduler, OmniSocials included, publishes through TikTok's Content Posting API, so the right column is what a scheduled post must fit. OmniSocials resizes photos larger than 1080 × 1920 and converts PNG to JPEG before posting.

Tips

Size it once, post it anywhere. Six rules that cover most posts.

Default to 1080 × 1920
It fills the screen, fits TikTok's API, and meets the 1080p the Creator Rewards Program asks for.
Fill the frame, skip the bars
TikTok says blurred bars shrink your subject into a small box. Crop in so the subject fills the screen.
Keep the subject centered
TikTok's advice: keep your image centered and not covered by any buttons on the screen.
Keep photos at 1080p or less
Through the API, photos go up to 1080p. OmniSocials resizes larger photos for you.
Use JPEG or WebP for photos
TikTok's API takes only these two formats. OmniSocials converts PNG to JPEG before it posts.
Pick the cover frame
Through a scheduler, the cover is a frame from the video. Pick a moment that reads well as a thumbnail.

Publishing

Upload any photo. OmniSocials resizes it to fit TikTok and converts it to JPEG.

Every size on this page comes from TikTok's Creator Academy, Help Center or Content Posting API, read on October 17, 2026. TikTok publishes no size for photo posts or a recommended profile photo, so the page labels the commonly used figures. TikTok's ad help center offers safe-zone overlay files but no pixel numbers, so the page gives none.
