FAQPage Schema
How do I design a banner for social media with correct dimensions?▼

Specify the platform and the skill applies exact dimensions from its size reference, such as 1500x500 for Twitter/X headers or 1080x1920 for Instagram stories. It keeps critical content within the central 70-80% safe zone and exports the final PNG at the exact size.

What banner sizes does Google Display Network require?▼

Common Google Display sizes include 300x250 medium rectangle, 728x90 leaderboard, 300x600 half page, and 320x50 mobile banner. The reference file lists all supported sizes with notes on performance, such as the medium rectangle having the highest CTR.

When should I use the Standard versus Pro image generation model?▼

Use the Standard Flash model for backgrounds, gradients, patterns, and quick A/B variants at 2K resolution. Use the Pro model for hero illustrations, product shots, and photorealistic scenes requiring 4K detail.

Can this skill handle video editing or full website design?▼

No, the skill explicitly handles banner design only and refuses out-of-scope requests. It does not perform video editing, full website design, or print production work.

What design rules apply to text on ad banners?▼

Ads should keep text under 20% of the canvas since Meta penalizes heavy text. Use a maximum of two typefaces, minimum 16px body text, at least 32px headlines, and a 4.5:1 contrast ratio with one CTA per banner.
