16:9 vs 9:16: where SaaS explainers convert

SaaS doesn't get to pick one aspect ratio. The homepage wants wide; the feed wants tall. Here's where each shape earns its keep, and why you should build both from a single production.

16:9, the wide cut

This is the classic landscape video. It belongs on your homepage hero, your YouTube channel, your Product Hunt gallery, and anywhere it sits inside a layout with room around it. It's the format buyers expect when they're evaluating you on a desktop, and it's the one that reads as "this is a real company."

9:16, the tall cut

Vertical fills a phone screen. It belongs in Reels, Shorts, TikTok, Stories, and most paid social placements. People scroll these fast and muted, so the tall cut needs the hook on screen as text in the first second and captions throughout. The same script, recut for the thumb.

Where each one goes

Build both from one production

The script, voiceover, and key visuals are the expensive part, and they're shared. Reframing and recutting them into a second aspect ratio is cheap by comparison, so paying twice for it makes no sense. We build the 16:9 master and the 9:16 cut from one production, which is why both come together rather than as separate projects.

Hook variants for ads

Paid social rewards testing the first three seconds. From the same video, a couple of alternate hooks let you run an A/B on the part that decides whether anyone watches. The body stays the same; only the opening changes.

For the launch case specifically, the vertical cut does most of the social lifting. See the Product Hunt launch-video playbook, or go back to the complete guide. When you're ready, start your video.
