For smartphones
When delivering ads for smartphones, using the double (600x500, 640x200, 640x100) or more pixel-size images in the same aspect ratio is recommended. The smartphones usually have higher screen resolution than PC, and your ads appear more clearly when you use the images that are more than double size.
For images with aspect ratio 6:5, create a 600×500 pixel image, double-size or more of the minimum size 300x250.
You can check how your image looks in the 画像広告のスマートフォン表示シミュレーター (image simulator for smartphones). Drag and drop your image in the gray area at the lower part of the page. (The page isn't available in English.)
