The Complete TikTok Video Size Guide for 2025

If you want your TikTok videos to look sharp, load fast, and perform well, you need to know the right TikTok video size, format, and aspect ratio. We’ve tested, failed, and learned what works best when creating content that reaches more people. Here’s the ultimate guide to TikTok video specs, written with years of real-world experience.

👉 Quick Answer: The recommended TikTok video size is 1080 x 1920 pixels, with a 9:16 aspect ratio, in .MP4 format, and under 287 MB.

TikTok Video Dimensions You Should Use

The TikTok app is designed for vertical viewing. That means the right video dimensions make a big difference.

• Best choice: 1080 x 1920 pixels (vertical video)
• Alternative: 1920 x 1080 pixels (horizontal, less engaging)
• Square video: 1080 x 1080 pixels (works but feels cramped)

👉 Snippet Answer: TikTok recommends 1080 x 1920 px vertical videos for the best quality and user experience.

If you also work with clipping path services for eCommerce product photos, you’ll notice the same principle applies—vertical, high-resolution visuals perform best.

TikTok Video File Size Limits

The file size you upload depends on your device and whether it’s organic or an ad.

• iOS: Up to 287.6 MB
• Android: Up to 72 MB
• TikTok Ads: Up to 500 MB

👉 Snippet Answer: Keep TikTok videos under 287 MB on iOS and 72 MB on Android to avoid compression.

TikTok Video Formats That Work Best

TikTok supports a few video file formats, but not all perform equally well.

• Recommended: MP4
• Also accepted: MOV, AVI (ads only)

👉 Snippet Answer: Use .MP4 format for TikTok videos—other formats may work, but MP4 ensures best quality.

TikTok Video Length: What Works Best

You can post long videos now, but shorter ones still get more attention.

• Minimum: 3 seconds
• Maximum: 10 minutes
• Best range: 15–60 seconds for higher engagement

👉 Snippet Answer: The ideal TikTok video length is 15–60 seconds for best engagement.

TikTok Aspect Ratio and Safe Zones

Even with the right size, text placement matters.

• Avoid bottom 150 px (covered by captions and UI).
• Avoid top 200 px (covered by profile info).
• Keep text in the center for visibility.

👉 Snippet Answer: TikTok’s safe zone is the middle area of the screen, avoiding top and bottom UI overlays.

TikTok Video Ads Specs

If you’re running ads, specs are stricter.

• In-Feed Ads: 1080 x 1920 px, 5–60 seconds
• Brand Takeover: 1080 x 1920 px, 3–5 seconds
• Top-View Ads: 1080 x 1920 px, 5–60 seconds

👉 Snippet Answer: TikTok Ads work best at 1080 x 1920 px, MP4 format, under 500 MB.

TikTok Video Resolution

Resolution affects clarity and engagement.

• Best: 1080p Full HD
• Acceptable: 720p (lower engagement)
• Avoid: Below 720p (blurry, low-quality)

👉 Snippet Answer: For TikTok, use 1080p resolution for sharp and clear videos.
