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.
What happens if my subject line 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.
