FAQ
Gmail subject (Android): questions
What is the Gmail subject (Android) limit?
About 33 characters (211px). About 33 characters show on a Pixel 7, the tightest common inbox. Modeled as a pixel box calibrated to the character count seen on the device, so wide and narrow letters are handled.
Why test Gmail on Android first?
It’s the tightest common inbox: about 33 characters of subject show on a Pixel 7, fewer than iPhone Mail. If your subject fits here, it fits nearly everywhere.
What happens if my subject line is too long?
Gmail · Android still shows it, but cuts it with “…”, and anything past the cut is invisible to most people.
Why does the character count change?
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.
