TikTok Video Dimensions & Size Guide (2025 Updated)

To go viral on TikTok, your content needs to look crisp. Posting a pixelated video or one with black bars is the fastest way to get scrolled past. Here is the definitive guide to TikTok video specifications for 2025.

Deep Dive

1. Aspect Ratio (9:16)

TikTok is a mobile-first platform. Always shoot and edit in 9:16.

• Avoid: 16:9 (Landscape) - unless you want users to turn their phones, which they rarely do.
• Avoid: 1:1 (Square) - it leaves too much empty space.

2. Resolution (1080p vs 4K)

While modern phones shoot in 4K, TikTok compresses everything to 1080p.

• Tip: Record in 4K for editing flexibility, but export your final project in 1080p. Uploading a 4K file often results in worse quality because TikTok’s server compression is harsh. Let your editor compress it to 1080p nicely instead.

3. File Size Limits

• Android: ~72MB
• iOS: ~287MB If your file is larger, TikTok will crush the quality to make it fit. Keep your bitrates reasonable.

4. Safe Zones

Don’t put text or important visuals on the very edges!

• Bottom: Covered by the caption and username.
• Right Side: Covered by the like/share/comment buttons.
• Top: Covered by the “Following/For You” tabs.
• Rule of thumb: Keep important text centered.
