    Portrait Ads for Social Media: 9:16 Vertical Creatives

    Vertical video is the norm on Instagram Stories, TikTok, Reels, and YouTube Shorts. Portrait format (9:16) fills the screen on mobile—where most users are. If you're advertising on these platforms, you need vertical creatives.

    AI can generate 9:16 ads in seconds. Kubeez supports vertical aspect ratio across all image and video models. Here's how to create portrait ads that perform.

    #Why 9:16?

    Mobile-first: Phones are held vertically. Full-screen vertical ads feel native and immersive.

    Platform fit: Stories, Reels, Shorts, and TikTok are all vertical. Ads that match the format get higher engagement.

    Attention: Vertical fills the screen. No letterboxing, no wasted space. Viewer is fully immersed.

    #Platform-Specific Tips

    Instagram Stories: 9:16, 1080x1920. Keep text and CTAs in the center—edges can be cut off on some devices. Safe zone: 250px from top and bottom.

    TikTok: 9:16, vertical. Native, authentic feel. UGC-style content often outperforms polished ads. Consider trending sounds and formats.

    Reels: Same as Stories. Hook in the first 1–2 seconds. Vertical format favors quick cuts and dynamic content.

    YouTube Shorts: 9:16, up to 60 seconds. Vertical, with captions (many watch without sound).

    #Composition for Vertical

    Top: Logo or branding. Hook or headline.

    Middle: Main visual—product, person, or key message. This is the focus.

    Bottom: CTA, secondary message, or link. Avoid placing critical info at the very bottom.

    Thumb: Consider the thumbnail. On some platforms, the first frame is the preview. Make it compelling.

    #Aspect Ratio in Kubeez

    Use aspect_ratio: "9:16" when generating. For video, Kling 2.6, Veo 3.1, and others support 9:16. For images, Nano Banana and GPT-1.5-image support it.

    #Best Practices

    • Hook fast: First 1–2 seconds determine if they keep watching. Lead with the most compelling element.

    • Captions: Many watch without sound. Use captions or on-screen text.

    • Test: Try different hooks, lengths, and styles. Vertical allows rapid iteration.
