Apple Mail · iPhone · Preheader
About 99 characters over two lines on an iPhone 14. Modeled as a pixel box calibrated to the character count seen on the device, so wide and narrow letters are handled.
Last reviewed · How we measure
On some iPhones, Apple may show its own short summary instead of your preview text. Your subject line is the part that always shows, so make sure it works on its own. That means the text on this screen may not show at all.
Under the subject, iPhone Mail shows two lines of preview text, taken from the preheader or the first text in your email.

About 98 characters (716px over 2 lines). About 99 characters over two lines on an iPhone 14. Modeled as a pixel box calibrated to the character count seen on the device, so wide and narrow letters are handled.
It’s the text Mail shows under the subject. It comes from a hidden preheader if you set one, or else from the first words of the email body.
Apple Mail · iPhone still shows it, but cuts it with “…”, and anything past the cut is invisible to most people.
This screen cuts by width, not characters. Wide letters like W and M use up to four times the room of i or l, so two texts of the same length can be cut in different places.
