What is the recommended character limit for title tags to avoid truncation in search results?

The recommended character limit for title tags to avoid truncation in search results is approximately 60 characters. While Google's display width is based on pixels, not characters, 60 characters generally fits within the typical display width on most devices. Exceeding this limit often results in your title tag being cut off, which can negatively impact click-through rates as users may not see the full context of your page's content. 40 characters is too restrictive and may not allow for sufficient descriptive power. 80 and 100 characters are generally too long and will almost certainly be truncated, reducing their effectiveness.
