Getting the Right TikTok Video Size
The right video size makes your TikTok posts look more professional and perform better. TikTok works best with a vertical aspect ratio of 9:16, which perfectly fits a smartphone screen. The recommended resolution is 1080 × 1920 pixels, though the platform accepts a minimum of 720 × 1280 pixels.
TikTok has file size and length limits depending on the video:
- Up to 3 minutes: maximum 500 MB
- Between 3–10 minutes: maximum 2 GB
- Duration: minimum 3 seconds, maximum 10 minutes
Device-specific maximum file sizes are:
- Android: 72 MB
- iOS: 287 MB
- Web uploads: 500 MB
Supported formats include MOV, MPEG, AVI, 3GP, and MP4. Frame rates of 23.98 up to 60 fps are allowed, with 30 or 60 fps recommended for smooth motion. Higher bitrates can improve quality, but TikTok compresses your video during upload to fit platform standards.
What’s the correct TikTok video dimension?


Audience engagement will depend on the quality of your video. Your TikTok video dimensions must be 1080×1920 for best results. The standard TikTok aspect ratio is 9:16 for the best visual experience. 1:1 is also supported, but it won’t be as immersive as filling up the entire screen.

TikTok Video Dimensions: Portrait or landscape?
When filming a TikTok video — especially on your phone — one of the first choices you’ll face is whether to shoot in portrait (vertical) or landscape (horizontal) mode.
Portrait videos (with a 9:16 aspect ratio) are taller than they are wide and fill the entire mobile screen. Landscape videos, on the other hand, use a wider 16:9 ratio, similar to traditional TV or computer screens.
If your video is made specifically for TikTok, portrait (9:16) is the way to go. This is TikTok’s native format, meaning it fills the screen without black bars and matches the viewing experience users expect. If you plan to share the same video across multiple platforms, you can use landscape, but it won’t look as polished on TikTok and will display with black bars above and below.
Why Portrait Videos Work Best on TikTok
Advantages of portrait videos:
- Full-screen experience: Vertical videos take up the entire screen, making the viewing experience more immersive.
- Platform-friendly: TikTok’s interface and algorithm favor vertical videos, which also work well on Instagram Reels and YouTube Shorts.
- Higher engagement: Since people naturally hold their phones vertically, these videos feel more comfortable to watch — and tend to get better engagement.
Disadvantages of portrait videos:
- Limited frame: The narrow frame can restrict how much you can fit in one shot, limiting creative possibilities.
- Less versatile: Portrait videos don’t always look great on platforms that prefer landscape or square formats.
When Landscape Videos Make Sense
Advantages of landscape videos:
- Familiar look: This format feels more traditional and works well across platforms like YouTube or Facebook.
- Wider view: A landscape frame lets you capture more of the scene, which is ideal for certain types of content.
- Easier to adapt: It’s simpler to crop a landscape video into a vertical or square format than the other way around.
Disadvantages of landscape videos:
- Not optimized for TikTok: Since TikTok favors vertical videos, landscape content may not perform as well in the algorithm.
- Smaller on screen: On TikTok, landscape videos appear smaller and don’t fill the screen, which can hurt engagement.
What’s the biggest video you can post on TikTok?
The size limit for a TikTok video depends on your phone. Android users can upload videos up to 72 MB. iPhone users get more space—up to 287.6 MB.
Both Android and iPhone users have similar experiences editing videos if they know how to use tools like Simplified video editor. Right now, TikTok lets you post videos that are up to 1 minute long. But we’ve heard they might let us post 3-minute videos soon. It’ll be interesting to see how that changes things!

Best File Formats for TikTok Videos
TikTok officially accepts two video file formats:
- .MP4 (MPEG-4)
- .MOV (QuickTime)
Both formats are popular and work well with most smartphones, cameras, and editing tools. Of the two, MP4 is the more commonly used option, as it delivers high-quality video with smaller file sizes, making uploads quicker and more efficient.
Formats Not Supported
TikTok does not support formats like AVI, WMV, MKV, or FLV. If your video is in one of these formats, you’ll need to convert it to MP4 or MOV before uploading.
Types of Video Ads on TikTok


Most TikTok users are between 13 – 40 years old. By reaching such a wide target audience, including the Gen-Z population, TikTok video ads boost the business potential of this platform.
TikTok also offers a variety of advertizing tools and solutions to narrow down your target groups. But while making ads, you must be careful of the proper TikTok video size. The best thing is that TikTok allows up to 500 MB for ads. That gives you a lot of space for high-quality content.
TikTok video ads are a key component of your TikTok marketing strategy. Here are some important notes that can help you get the best out of them.
