Can Wan 3.0 Generate Vertical Videos?

Overview

Yes. Current WaveSpeedAI Wan 3.0 pages list 9:16 among supported aspect ratios, so teams can plan vertical videos where the selected route exposes that setting. Confirm the endpoint before launch because defaults and variant behavior can change.

Vertical video should be designed vertically from the start. Put the main subject inside the center-safe area, avoid important motion at the edges, and leave room for captions, app UI, product overlays, or calls to action if they will be added later.

For product and ad work, test the vertical format with real placement in mind. A camera move that works in widescreen may feel cramped in 9:16. Product labels, faces, and hands also need closer review because vertical framing can crop important context.

WaveSpeedAI helps teams compare aspect ratios quickly through the same Wan 3.0 workflow. Save vertical prompts separately from 16:9 prompts, because the wording, camera language, and review criteria should not be identical. Keep accepted vertical examples in a separate prompt library for social workflows. That library should include placement notes for TikTok, Reels, Shorts, or in-app stories when relevant.
