AI Banner Ad Generator
Generate banner ads in every IAB size — leaderboard, skyscraper, medium rectangle and mobile — across 20+ models, ready to traffic in minutes.
What are the standard IAB banner ad sizes?
The most-trafficked IAB display sizes are the leaderboard (728 × 90), medium rectangle (300 × 250), wide skyscraper (160 × 600), large rectangle (336 × 280), half-page (300 × 600) and billboard (970 × 250), plus mobile leaderboards (320 × 50 and 320 × 100). The medium rectangle and leaderboard alone cover the majority of open-web inventory. VapuAI generates banner creative across 20+ image models and adapts one concept to each fixed size, so you can traffic a full set — desktop and mobile — without hand-building every dimension.

Questions, answered
Which banner sizes should I run?
The medium rectangle (300 × 250) and leaderboard (728 × 90) cover most open-web inventory. Add the wide skyscraper (160 × 600), half-page (300 × 600) and mobile leaderboards (320 × 50 / 320 × 100) for fuller coverage.
How do I keep a banner legible at small sizes?
Keep the message to a few words, use a strong focal image and refine the layout in place. Because you generate one concept and adapt it per size, you can tune each dimension so nothing gets cramped.
Does it cover mobile banner sizes?
Yes — mobile leaderboards at 320 × 50 and 320 × 100 are part of the standard set, so you can traffic desktop and mobile from the same campaign concept.
Are the banners cleared for paid placement?
Yes — commercial usage rights are included on every plan, so generated banners are cleared for programmatic and direct display buys out of the box.
