FAQ

Gmail preview text (Android): questions

What is the Gmail preview text (Android) limit?

About 37 characters (233px). About 37 characters of preview show on a Pixel 7. Modeled as a pixel box calibrated to the character count seen on the device, so wide and narrow letters are handled.

What happens if my preheader is too long?

Gmail · Android still shows it, but cuts it with “…” — 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.

Can I check many at once?

Yes — upload a CSV or Excel file on the Bulk page and Truncly checks and fixes every row, then gives the file back with fixes added.
