**Facebook Reels 2026: aspect ratio 9:16, recommended 1080x1920, caption up to 63,206 characters.**

## All specs

| Aspect ratio | 9:16 |
|---|---|
| Recommended resolution | 1080x1920 |
| Minimum resolution | 540x960 |
| Minimum length | 3 seconds |
| File types | MP4 |
| Maximum frame rate | 60 fps |
| Caption limit | 63,206 characters |

Notes (from the sources, in English): Since June 2025 all Facebook videos (except stories and live) are shared as reels and can be any length or orientation, so no max duration is given. Requirements page: MP4 recommended, 1080p, H.264/H.265 (VP9, AV1 supported), 24 to 60 fps, AAC stereo 128 kbps+. 1080x1920 / 540x960 minimum and 3 s minimum come from the Reels Publishing API, which still limits API reels to 3 to 90 s. Caption limit 63,206 is an industry figure.

In 9:16 the app covers parts of the top and bottom of your video. Check your frame with the [safe zone checker](https://shortformkit.com/safe-zone-checker/) or download the [safe zone templates](https://shortformkit.com/safe-zone-templates/) as PNG.

Work out bitrate and file size with the [file size calculator](https://shortformkit.com/video-file-size-calculator/). Check caption length with the [character counter](https://shortformkit.com/character-counter/).

## Changes in 2025 and 2026
