Social media video specs
cheat-sheet
Every platform wants a slightly different size, ratio and length, and getting one wrong means a cropped clip or a rejected upload. Here is the whole lot in one place: the dimensions, aspect ratios, length limits and formats for TikTok, Instagram, YouTube, Facebook, LinkedIn and X, tuned to current 2026 layouts.
Short version: export vertical clips at 1080 × 1920 (9:16), feed posts at 1080 × 1350 (4:5) or 1080 × 1080 (1:1), and landscape at 1920 × 1080 (16:9). Use MP4 with H.264 and you will play everywhere. Then grab the matching safe-zone overlay so your captions and logos never get covered.
Vertical · 9:16
1080 × 1920Full-screen vertical, the default for TikTok, Reels and Shorts. Shoot and export at 1080 × 1920. Keep captions and logos inside the safe zone so the platform UI never covers them.
Feed & Square
1080 × 1350 · 1080 × 1080Feed video posts. 4:5 (1080 × 1350) takes the most height in a scrolling feed; 1:1 square is the safe middle ground that reads the same everywhere. No fixed platform UI, so use broadcast action-safe and title-safe guides.
Landscape · 16:9
1920 × 1080Widescreen, for YouTube, LinkedIn and X. Export at 1920 × 1080 (or 3840 × 2160 for 4K on YouTube). Keep titles inside the title-safe area and important motion inside action-safe.
Conservative 2026 reference. Platforms change limits with app updates, so check the platform's own help page for the exact latest figure before a large upload. Dimensions and aspect ratios are the stable values to design around.
Frequently asked questions
What size should a TikTok, Reel or Short be?
All three use 9:16 vertical at 1080 × 1920, exported as MP4 (H.264). That single size covers TikTok, Instagram and Facebook Reels, and YouTube Shorts. Keep text inside the safe zone so the platform UI never covers it.
What is the best video format to upload?
MP4 with the H.264 codec is the safe default everywhere. It plays on every platform and device without conversion. If your export is in MOV, ProRes or another format, convert it to MP4 before sending or uploading.
What aspect ratio is best for each platform?
9:16 vertical for TikTok, Reels and Shorts. 4:5 or 1:1 for feed posts. 16:9 landscape for YouTube, LinkedIn and X. Match the ratio to where the video will live, and use a safe-zone overlay to keep content clear of the UI.
Are these specs up to date?
These reflect current 2026 platform guidance and are kept conservative. Platforms adjust limits with app updates, so treat them as a working reference and check the platform's own help page for the exact latest limit before a big upload.
