Google Ads image size is not one number. It is a ratio per placement plus a size ceiling per asset type: 150 KB for classic display image ads, 5120 KB for responsive display marketing images and logos.
Ratio and recommended pixels per placement. - Marketing image, responsive display, 1.91:1: 1200 by 628 recommended, 600 by 314 minimum. This is the one that appears most across feeds and banners.
The size limits: where 150 KB and 5120 KB split. These two caps are constantly confused, and it is usually the first one that stops a creative from running. - Classic display image ads: 150 KB per file, in JPG, PNG or animated GIF.
Four steps to land inside the limit. - Set the dimensions first, compress second. Resizing and quality reduction are different operations, and doing them in the wrong order is what produces a 150 KB file that is too soft to use, usually because a 4000 pixel original was squeezed as-is.
Checklist before you upload. - Placement first: feed, banner or portrait decides which ratio you export first. - Lock the short edge to the recommended value in the 1200 series and let the long edge follow the ratio.
The part worth keeping: - Placement first: feed, banner or portrait decides which ratio you export first. Full write-up is on the source blog.
