Why the title tag character limit decides your click-through rate
Your page's title tag is the single most visible element in a Google search result — the blue headline that users read before deciding whether to click. Google displays titles up to roughly 600 pixels wide, which translates to approximately 60 characters for average-weight Latin text. Beyond that, the title is cut off with an ellipsis and the end of your message disappears.
Truncated titles consistently underperform complete ones. When a user can't read the full title, they lose the context that would have made them click. Worse, if the keyword that matches their search query is positioned toward the end of a long title, it may be the exact word that gets cut — eliminating the relevance signal that would have earned the click.
PostTruncate's Google SERP preview tool shows your title in a live Google-style snippet as you type. The preview updates instantly, so you can see whether your title fits cleanly or trails off with "…" before you publish the page.
Meta description length: 155 characters and the truncation risk
The meta description is the grey body text beneath the title in a Google search snippet. It doesn't directly affect rankings, but it has a significant impact on click-through rate — the proportion of users who see your result and choose to visit your page. A well-written meta description tells the user exactly what they'll find on your page and why it's worth their click.
Google truncates meta descriptions at approximately 155 characters on desktop (shorter on mobile). A description that runs to 200 characters may look complete in your CMS, but in the actual search result it ends mid-sentence — cutting off the call to action, the key benefit statement, or the specific detail that would have differentiated your result from competitors.
PostTruncate's meta description length checker counts your characters in real time and previews the description exactly as it will appear in a Google snippet, including the truncation point if you go over.
How Google actually decides what to show in snippets
Google doesn't always use your meta description verbatim. When the search query matches a passage on your page more closely than your meta description, Google may replace your description with an extracted snippet from the page body. This is not something you can fully control, but you can influence it. A meta description that reads like natural search intent — answering the query directly — is more likely to be preserved by Google than a generic marketing tagline.
The same principle applies to titles. If your title tag is too generic or too long, Google may rewrite it entirely. Keeping your title specific, under 60 characters, and front-loaded with the primary keyword gives Google less reason to override it.
The pixel-width nuance: why character count isn't the full story
Google measures title width in pixels, not characters. A title composed entirely of narrow letters like "i", "l", and "t" can fit more characters than a title using wide letters like "W", "M", and "m". PostTruncate tracks both character count and estimated pixel width simultaneously, flagging titles that are safe on character count but may still truncate due to wide characters. This is the same calculation Google uses — not a generic approximation.
Write once, preview before you publish
Most SEO writers draft in a CMS or spreadsheet, switch to a separate SERP preview tool, copy the text, check, adjust, then paste back. PostTruncate integrates the live SERP preview directly into the writing editor, so the entire workflow happens in one place. Type your title and description, see the Google snippet update in real time, confirm it looks right, and copy it to your CMS — no tab switching required.
