Start with the exact placement you need, then resize to that page's recommended or practical production target.

Are these google forms image sizes official?

Official platform sources are used where they publish exact specs. Practical targets are clearly labeled when a platform does not publish one fixed public pixel size.

Should I check mobile after upload?
