Video Aspect Ratios Explained: 16:9 vs 9:16 vs 1:1
Every platform wants a different shape of video, and getting it wrong is one of the fastest ways to lose the top or sides of your shot. Here's what each aspect ratio is for and how to shoot or resize for it correctly.
16:9 — widescreen
The standard for YouTube long-form, most TVs, and desktop viewing. If your video will primarily be watched on a laptop or TV, shoot and edit in 16:9.
9:16 — vertical
The format for YouTube Shorts, Instagram Reels, and TikTok. Shooting vertically from the start beats cropping a horizontal video after the fact, since cropping often cuts off subjects standing at the edges of frame.
1:1 — square
Less common now that most feeds default to vertical, but still useful for Instagram feed posts and some ad placements where a square crop displays consistently across devices.
Resizing without losing the shot
When you have to convert between ratios, the safest approach is a background-fill technique: place the original clip centered on a blurred or colored canvas sized to the new ratio, rather than cropping in tight. This keeps your entire original frame visible and avoids awkward zoomed-in crops that cut off hands, text, or a second person in frame.
