Medium Rectangle

How It Works

The Medium Rectangle or MREC is an IAB standard ad unit. The dimensions are 300 pixels wide by 250 pixels tall.

This ad unit is commonly placed above the fold. It is often used as part of a multi-size ad slot with a 300×600 ad unit. It is generally a strong performing ad size.

Many KBB ad programs include the Adaptive Responsive MREC.
