A practical reading of the limits
- Titles are measured by rendered width, not a fixed character count. Around 580 px is a useful desktop target.
- Descriptions are usually most comfortable around 145–160 characters, but Google may rewrite them for the query.
- Put the clearest value proposition first so the visible part still makes sense when the result is shortened.
Frequently asked questions
How long should a title tag be?
Google truncates title links by available device width rather than a fixed character count. This tool measures rendered width so you can see a practical approximation.
How long should a meta description be?
Aim for roughly 145–160 characters, while prioritising a useful first sentence. Google can choose different page text when it better matches a query.
Does Google always show my meta description?
No. Google may substitute text from the page when it better answers the search. Clear, specific copy that matches the page is most likely to be used.
Is this preview exact?
It is a close approximation using browser font metrics. Real results vary with device width, query bolding, and result features.
