Message Cards: Technical guidelines


● use horizontal layout, with approximately 2x1 aspect ratio (we recommend 650 x 290 px)

● cards look different from phone to phone, so try to keep some white space around the edges of images and avoid text and small details



● keep titles short to grab attention

● we suggest a maximum of 1 or 2 lines for the title (70-80 characters)


Body text

● there’s no limit for body text, and cards will scroll in full-screen mode

● in general, message cards work best if they are short; try breaking longer messages into more than one card
