Understanding the optimal sizes for TikTok posts makes sure that your content looks great and reaches the maximum audience. Here's a guide to mastering TikTok dimensions and video post size specifications.

TikTok Dimension Sizes

Creating content on TikTok takes a ton of time! You can create carousel posts on TikTok with our Social Media Kit in just a few minutes. Read more about our case study.

Video Post Dimensions

  • Standard TikTok Videos: The best dimensions are 1080x1920 pixels, adhering to the 9:16 aspect ratio. This orientation is perfect as it fills the entire screen of mobile devices, maximizing user engagement.

Ad Video Sizes

  • In-Feed Ads: For these ads, several resolutions work well:

    • 640x640 pixels (1:1 aspect ratio)

    • 720x1280 pixels (9:16 aspect ratio)

    • 1280x720 pixels (16:9 aspect ratio)

    • It’s crucial to choose the right aspect ratio to ensure your ad displays correctly on TikTok.

Video Length

  • TikTok videos can be as short as 3 seconds and as long as 10 minutes. The most popular lengths include:

    • 15 seconds

    • 1 minute

    • 3 minutes

    • Tailor the length of your video to your content and intended audience engagement.

File Size and Format

  • The maximum file size allowed varies by device:

    • 500MB for desktop

    • 287MB for iOS

    • 72MB for Android

  • Supported file formats include MP4, MOV, and for ads, additional formats like AVI.

Profile Picture and Carousel Image Sizes

  • Profile Picture: Minimum upload size is 20x20 pixels, but higher quality is recommended.

  • Carousel Images: Optimal dimensions are 1080x1920 pixels, with recommended aspect ratios of 9:16 or 1:1. Images with a 4:5 ratio are also acceptable but may not display as effectively.

Closing

Choosing the right TikTok post size will help you optimize your TikTok posts for visibility and engagement. Remember, choosing the right dimensions, lengths, and formats can significantly improve how users interact with your content on the platform.

Automate your visual content creation and publishing

If you are running a business, you already know the problem. Posting content is one thing. Doing it consistently across LinkedIn, Instagram, TikTok, Pinterest, and X while keeping everything on-brand is a full-time job you did not sign up for.

Situational Dynamics is an autonomous content engine that generates and publishes on-brand social media content for you. You fill out a short brand questionnaire. The system encodes your voice, colors, and audience into a design system. From that point forward, content arrives in your inbox ready for one-click approval, and approved posts get designed, rendered, and published automatically.

  • 150 posts per month, zero manual work. Static posts, carousels, and blog content are generated and published across up to 5 platforms. You never open a design tool, write a caption, or touch a scheduler.

  • Your brand, not generic AI output. Every post is rendered through your personal design system with your exact colors, typography, and voice. No two clients produce the same visual style.

  • One-click approval from your inbox. Content ideas land as interactive email cards. Tap approve. That is your entire involvement.

Stop configuring tools. Start receiving results.
