How to resize a video for every platform (without it looking cropped)
You shot one great video and now every platform wants a different shape — square for the feed, tall for Reels and TikTok, wide for YouTube. Stretch it or crop it carelessly and it shows immediately. Here's the difference between resizing and reframing, and how to do it properly for each platform.
Never just stretch a video to a new aspect ratio — it distorts everything in the frame. A straight crop is better but still risks cutting off your subject if they're not dead-centre. Proper reframing recomposes each part of the clip around whatever's actually happening in it, then you re-add captions and branding sized for the new shape. Doing this by hand in a video editor is realistic for one or two clips; past that, it's a job worth automating.
1Know which ratios you actually need
Most businesses only need two: tall for short-form video, and wide or square for everything else. Chasing every platform's exact spec is rarely worth it — these two cover the overwhelming majority of where video actually gets watched.
| Ratio | Where it's used |
|---|---|
| 9:16 (tall) | TikTok, Instagram Reels & Stories, YouTube Shorts |
| 1:1 (square) | Instagram feed, Facebook feed |
| 16:9 (wide) | YouTube, LinkedIn, most website embeds |
2Don't just crop or stretch — understand why each fails
- Stretching a 16:9 video to fit a 9:16 frame squashes or elongates everything in it — faces, products, straight lines all look subtly (or not so subtly) wrong.
- A straight centre crop keeps the middle of the frame and simply cuts the sides off. If your subject moves, stands off-centre, or the shot is a wide two-person scene, cropping can cut people out of their own video entirely.
Reframing recomposes each moment of the clip around what's actually happening in it — following a subject as they move, keeping faces and products in frame — rather than cutting a fixed rectangle out of the original.
3Reframe around the subject, not the original frame
If you're doing this manually in an editor, treat it like a fresh crop for every few seconds rather than one crop for the whole clip: reposition the frame as the subject moves, and prioritise faces and the product over background detail. It's slower than a single drag-to-crop, but it's the difference a viewer actually notices.
4Leave safe margins for platform overlays
TikTok and Reels both place their own UI — captions, like/share buttons, usernames — over the bottom third and right edge of a vertical video. Keep important text and faces out of those zones, or the platform's own interface will sit directly on top of what you most want seen.
5Rebuild captions and branding for the new shape — don't just shrink them
Text sized correctly for a wide 16:9 frame is often too small or badly positioned once it's inside a tall 9:16 one. Recreate on-screen text and any logo placement for each ratio rather than scaling the same overlay down to fit.
6Export at the right resolution
As a baseline: 1080×1920 for vertical (9:16), 1080×1080 for square, and 1920×1080 for wide (16:9). Exporting below these sizes is the fastest way for a video to look soft or compressed once a platform re-encodes it on upload.
Common mistakes worth checking for
- Posting the same file to every platform regardless of its native ratio, and letting the platform crop or letterbox it automatically.
- Captions or a logo that end up partly hidden behind a platform's own UI once posted.
- A crop that technically fits the new ratio but cuts off the one thing the video was actually about.
- Exporting at a low resolution "because it's just for social" — platforms compress further on upload, so low-res source footage degrades twice.
When it's worth automating
All six steps above work fine for a single hero video you're prepared to spend real editing time on. They stop being realistic the moment you have more than a couple of clips, or need several ratios from the same source regularly — recomposing footage frame-by-frame by hand doesn't scale, and that's specifically the kind of repetitive, rules-based task that's straightforward to automate well.
Reframe your video automatically
Upload a video and get it back properly recomposed for a different platform — subject kept in frame, not just cropped or squeezed.
- Can I just crop a landscape video to make it vertical?
- You can, but a straight crop keeps the middle of the frame and cuts the sides off completely — if your subject moves or isn't centred, cropping cuts them out too. Reframing tracks the subject and recomposes each part of the video, rather than slicing a fixed window out of the original frame.
- Do I really need a different version of a video for every platform?
- Not every platform, but the two aspect ratios that matter most are 9:16 (TikTok, Reels, Stories) and 16:9 or 1:1 (YouTube, Instagram feed, Facebook feed). One video posted in the wrong ratio typically gets cropped or letterboxed automatically by the platform, which looks noticeably worse than a version made for that ratio.
- What's the difference between reframing and resizing a video?
- Resizing (or stretching) changes the video's dimensions without changing what's in each frame, which distorts anything that isn't the original shape. Reframing recomposes each frame to a new aspect ratio while keeping the actual subject centred, sharp and undistorted — it's closer to a fresh crop than a stretch.
