TikTok Size: The Complete Guide to TikTok Video Sizes, Dimensions, Resolution, and Aspect Ratios for Creators and Businesses 

Use 1080 x 1920 pixels, a 9:16 aspect ratio, and vertical video for TikTok. That is the cleanest setup for most creators, shops, coaches, artists, and brands. If you remember nothing else, remember this: full-screen vertical wins.

TLDR: TikTok’s best video size is 1080 x 1920 pixels, with a 9:16 vertical aspect ratio. Export as MP4 or MOV, keep text away from the edges, and aim for clear 30 fps or 60 fps video. For example, a small bakery posting a 15-second vertical cake video may keep more viewers than the same clip posted sideways. If 1,000 people watch, even a 20% better completion rate can mean 200 more full views.

Best TikTok Video Size

The best TikTok size is:

• Width: 1080 pixels
• Height: 1920 pixels
• Aspect ratio: 9:16
• Orientation: Vertical
• Format: MP4 or MOV
• Frame rate: 30 fps or 60 fps

This fills the phone screen. No black bars. No tiny video floating in space. No sad crop that cuts off your face right when you say the good part.

Honestly, it feels like every editing app hides the export button in a different cave. But once you find it, choose 1080 x 1920. Save that as your default.

TikTok Aspect Ratios Explained

An aspect ratio is just the shape of your video. It compares width to height.

• 9:16: Best for TikTok. Tall and vertical.
• 1:1: Square. Works, but wastes screen space.
• 16:9: Wide video. Fine for YouTube, weaker on TikTok.

Think of TikTok as a phone-first app. People hold phones upright. So your video should stand upright too.

A 16:9 clip can still upload. But it often looks small. It may show empty space above and below. That space could have been your product, your face, your offer, or your joke.

Recommended TikTok Resolution

1080p is the sweet spot. That means 1080 x 1920 for vertical content. It looks sharp and still uploads without causing too much stress.

You can upload higher sizes, like 2160 x 3840. That is 4K vertical. It can look great. But it also creates bigger files. Bigger files can take longer to upload. They may also get compressed by TikTok anyway.

So be practical:

• Use 1080 x 1920 for most videos.
• Use 4K only if your footage is very detailed.
• Avoid low-res clips under 720p if you can.

Blurry video can make a good idea feel cheap. Sharp video helps people stay. Simple as that.

TikTok Safe Zones

This part saves headaches.

TikTok covers parts of your video with buttons, captions, usernames, icons, and the comment area. If you place text too low, it may get buried. If you place text too far right, the like button may sit on top of it.

Keep key text and faces near the center. Leave breathing room on every edge.

• Keep important text away from the bottom 250 pixels.
• Avoid placing text on the right side.
• Keep faces and products near the middle third.
• Test your video before posting.

It drives me crazy when a perfect caption gets hidden under the username. That tiny mistake can make a clear video feel messy.

TikTok File Size and File Type

TikTok accepts common video formats. The safest choices are:

• MP4
• MOV

For most creators, MP4 is the best pick. It works almost everywhere. It gives good quality without giant file sizes.

File size limits can vary by device, upload method, and account type. As a stress-free rule, keep most videos under 500 MB. Short clips should be far smaller than that.

If your 20-second video is 1.8 GB, something went wrong. Check your export settings. You probably used a very high bitrate or exported in a huge format.

Best TikTok Length

Size is not only pixels. Length matters too.

TikTok supports short and longer videos, but attention is still brutal. People swipe fast. Your first two seconds do heavy lifting.

Good length ranges:

• 7 to 15 seconds: Best for quick jokes, product shots, tips, and hooks.
• 15 to 30 seconds: Great for mini tutorials and before-and-after clips.
• 30 to 60 seconds: Useful for stories, reviews, demos, and education.
• Longer videos: Best when the topic truly needs time.

A short video is not always better. A complete video is better. Cut the fluff. Keep the payoff.

TikTok Cover Size

Your TikTok cover is the still image people see on your profile grid. Use the same vertical size:

• Cover size: 1080 x 1920 pixels
• Aspect ratio: 9:16

But here is the annoying part. Your profile grid may crop the cover into a smaller preview. So keep title text in the center.

A good cover should answer one question fast: Why should I tap this?

Try cover text like:

• “3 Hooks That Work”
• “$19 Outfit Idea”
• “Before and After”
• “Don’t Make This Mistake”

TikTok Ad Video Sizes

Businesses should also use vertical 9:16 video. Ads need to feel native. If your ad looks like a recycled TV spot, people smell it in half a second.

Recommended TikTok ad specs:

• Size: 1080 x 1920 pixels
• Aspect ratio: 9:16
• Format: MP4, MOV, MPEG, or AVI
• Length: 9 to 15 seconds is often a strong start
• Audio: Use clear voice, music, or sound effects

For a product ad, show the product in the first second. Not the logo. Not a long intro. The product.

Example: a skincare brand could open with dry skin on screen, then show the cream, then show the result. Fast. Clear. No mystery.

Best Export Settings for TikTok

Use these settings before you upload:

• Canvas: 1080 x 1920
• Ratio: 9:16
• Format: MP4
• Codec: H.264
• Frame rate: 30 fps or 60 fps
• Bitrate: 8 to 12 Mbps for 1080p is usually fine
• Audio: AAC, 44.1 kHz or 48 kHz

If you shoot on a phone, you are already close. Record vertically. Use good light. Clean your lens. Yes, really. A smudged lens can ruin a $5,000 idea.

Common TikTok Size Mistakes

Avoid these classics:

• Uploading horizontal video with black bars.
• Placing captions too low where buttons cover them.
• Exporting at tiny resolution and getting a blurry post.
• Using huge file sizes that take forever to upload.
• Forgetting the cover crop on the profile grid.

Expect to waste time on one or two test uploads if you are new. That is normal. Annoying, but normal.

Quick TikTok Size Cheat Sheet

Final Takeaway

For TikTok, vertical is the move. Use 1080 x 1920 pixels, keep the 9:16 ratio, and place important text near the center. Export as MP4. Keep it sharp, quick, and easy to watch.

The right size will not save a boring video. But the wrong size can hurt a great one. Give your idea the full screen it deserves.
