How to resize a video ad for every placement

Calculated by dividing the target ratio by 16:9 at the same height, for example (9 ÷ 16) ÷ (16 ÷ 9) ≈ 0.32.

1. Decide what each shot is about: a face, a product, a screen detail.
2. For each ratio, move the crop to keep that subject, shot by shot.
3. Reposition and resize on-screen text for the new frame.
4. Check every placement's safe zone; vertical placements cover the bottom of the frame.
5. Re-time where needed: Stories split long ads into cards, Feed is often muted.

Shooting or generating with the vertical frame in mind from the start avoids most of these problems: keep subjects central, leave headroom, and capture close-ups that work at any ratio.

• The key action happens across the full width of a horizontal shot.
• The ad relies on text laid out for widescreen.
• The placement needs a different structure, such as a bumper or a Stories first card.

Placing a horizontal video inside a vertical frame with bars above and below is accepted by most platforms, but it wastes most of the screen and reads as a repurposed ad. Use it only as a last resort.
