Why is Facebook cropping my Reel? Causes & fixes
Check whether the crop is in your original export or only in the Facebook placement preview. Do not infer Facebook behavior from Instagram. Use a 9:16 editing crop only if that preview suits your intended placement.
Check these first
- Source aspect ratio vs. 9:16
Likely causes
- Source isn't 9:16
When a video in a different shape is placed into a 9:16 frame, the player may crop, pad or scale it. Preview the exact placement; the editing target is not a universal acceptance rule.
Fix it
- Crop to 9:16 before uploading
The linked crop tool center-crops files up to 100 MB; check the generated copy before using it. Use your editor for an adjustable crop or padded canvas, and keep the original.
