Lauren WakefieldTraditional ad formats often don’t fit seamlessly within retail websites and apps, leading retailers and ad tech companies to create custom formats. While these bespoke solutions can boost engagement, they also add complexity to planning, buying, and measuring Retail Media campaigns, increasing costs and limiting scale.
To address this, our Retail & Commerce Media Committee has developed the Flexi Ad Sizes Guidelines for Retail Media Networks. Created in collaboration with Tesco Media, the guidance recommends four flexible aspect ratios for static display ads, designed to work seamlessly across devices.
The approach reduces operational complexity, unlocks broader budgets, and improves the customer experience, while maintaining flexibility for innovation.
