How to Enable/Exclude Bidders Based on the Screen-size?

There is no point in showing desktop ads on mobile screens when a demand partner specifically bids on mobile. So, learn how to enable/exclude bidders based on the screen-size in this post.

If you’re working with a demand partner who’s only specialized in mobile, then there’s no point in sending them ad request (via header bidding) for page views from Desktop. You can skip the partner and save a few milliseconds. After all, the partner wouldn’t likely to win the impression, even if it bids.


You can use SizeConfig function to create labels based on the screen size. Refer the screenshot from prebid below.

bidder: “mobileBidder”,
labelAny: [“phone”], // this bid only applies to small screen sizes
params: {
placement: “2000”
