The right video size for Instagram Reels and TikTok
October 24, 2026 1 min read
Reels, TikTok and YouTube Shorts are made for vertical video. Upload the wrong ratio and your video looks tiny or gets cropped where you don't want.
Reels and TikTok sizeMake a video 9:16, 1:1 or 4:5.The right ratio: 9:16
For full screen vertical video on all three platforms, the ratio is 9:16. The recommended resolution is 1080 x 1920 pixels, but 720 x 1280 also looks sharp on a phone and makes a smaller file.

Three ways to turn a horizontal video vertical
If you have a horizontal (16:9) video, you can make it vertical in three ways:
- 1Crop: cuts part of the picture to fill the screen. Best when the subject is centered or you can pick the framing yourself.
- 2Blurred background: keeps the whole picture and fills the gaps with a blurred copy. The most popular style on social media.
- 3Borders: keeps the whole picture and leaves the gaps black.
Before you post
If the video is long, check the platform's length limits and trim it first if needed. In the resize tool you can drag to pick the framing and see the result in the preview before processing.
