What is this tool?

Search result titles can truncate when too long. This tool compares two title variants for character count and approximate pixel width, with a SERP-style preview. It is not affiliated with Google and does not predict rankings.

How to use it

  1. Enter title variant A and variant B.
  2. Compare length, pixel width estimate, and truncation risk.
  3. Pick a clearer, safer length for your audience.
