Apple Messages for Business

This section covers the different rich templates you can create and use on Apple Messages for Business

Image size guide

When creating interactive messages when selecting the style options use the following images sizes for the best formatting:

• Icon: 40 x 40 points at @3x scale (120 x 120 pixels)

• Small: 60 x 60 points at @3x scale (180 x 180 pixels)

• Large: 263 x 150 points at @3x scale (789 x 450 pixels)

Received messages should use the Large icon style and Reply messages should use the icon style.

For list picker images these should be:

• 180px × 180px (60pt × 60pt @3x resolution).

Apple requires all images in interactive messages and rich link previews to be PNG, with a maximum binary size of 200 KB per image. Bird converts your images to PNG and downscales oversized ones automatically — note that animated GIFs become static images. Regular image and file attachments are not affected.

Text limits

Any text rendered in the Messages app UI — titles, subtitles, labels, hint text, and button text — is limited by Apple to 200 characters. Longer values are truncated before sending, so keep UI text concise.
