FAQ
Gmail subject (desktop): questions
What is the Gmail subject (desktop) limit?
About 88 characters (562px). About 88 characters at a 1400px-wide window; the preheader fills whatever is left. Modeled as a pixel box calibrated to the character count seen on the device, so wide and narrow letters are handled.
How long can a Gmail subject line be on desktop?
About 88 characters show in a 1,400-pixel-wide window, but the row is shared with the preview text, so shorter subjects show more of both.
What happens if my subject line is too long?
Gmail · Web 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.
