Header Image (Advert) Dimensions

Hi there,
Just wondering what the dimensions should be for a advert in the header widget?

Also, the header image widget area recommended making the advert image responsive, I’m not sure what it means by this.



The Ad image size in header is 728x90px and by making it responsive means it won’t go off-screen on mobile to show the full 728px width image, so on mobile it will adapt to the screen-size, but will loose the exact size, so it won’t be a fixed size image and if you use Google Responsive Ads, then on mobile Google will replace the ad image with a smaller / other sized / aspect ratio image to make the ad to look good on the screen-size of the device from what your site was visited.

Best Regards,
