Why Dimensions Matter More Than You Think
Upload a horizontal video to Instagram Reels and watch it get cropped into oblivion. Share a 4K file to Twitter and see it compressed into a blurry mess. Video dimensions and aspect ratios matter because every platform has different requirements.
This guide gives you the exact specs you need in 2026. I've verified these against each platform's current documentation.

Frequently Asked Questions
What's the best aspect ratio for all platforms?+
There's no single best ratio. 9:16 vertical works for TikTok, Reels, Stories, and Shorts. 16:9 landscape works for YouTube and Facebook. 1:1 square is a safe middle ground.
Does VidSaveo show video dimensions?+
Yes. When you paste a video link, VidSaveo shows available formats with their resolution and dimensions so you can choose the best option.
What happens if I upload the wrong dimensions?+
Most platforms will auto-crop or add black bars to fit. The result usually looks unprofessional, so it's best to match the recommended dimensions.
Can I resize videos after downloading?+
Yes. Free tools like HandBrake, CapCut, or the built-in editors on most phones can resize and crop videos to match specific platform requirements.
