This offer is not positioned for experimental or one-off creative use cases.

Fluid 250 is a full-width display ad format that replaces the standard 970×250 with a responsive, edge-to-edge canvas that adapts to the user’s screen and device.

Unlike fixed IAB units, Fluid 250:

  • Uses the entire available viewport width

  • Creates more space for messaging, motion, and interaction

  • Maintains the same media placement while delivering stronger engagement

It is designed for performance-minded display buyers, not experimental or one-off creative.
