Google Ad Specs and Dimensions 2026
Google Ads spans an enormous range of placements — Search, Display, YouTube, Shopping, Performance Max, and beyond — and each one comes with its own set of rules. Get an image ratio wrong, exceed a file size limit, or overlook a character count, and your ad either gets disapproved or renders badly where it matters most. This cheat sheet cuts through the complexity and puts every Google Ads creative dimension, file type, aspect ratio, and copy limit in one clean, scannable reference — so you can build with confidence and stop losing time to trial and error.
