How does your page look in Google?
Google cuts titles and descriptions by pixel width, not character count. Paste a page and see the exact snippet, what gets truncated, and how to shorten it.
Fetches the page from outside your network and reads its title, description and canonical. Nothing is stored.
How this works
The tool fetches the page server-side (a browser cannot, cross-origin), reads the title and meta description, then measures them in the browser with the same font Google uses for results. Titles are cut at about 580 pixels and descriptions at about 920 on desktop, so a title can be under 60 characters and still be truncated.
What the SERP snippet preview measures
The tool fetches the page you name and reads its title tag, meta description and canonical URL. It then measures the title and description in the browser with the font Google uses for results, and compares the width against the point where Google truncates: roughly 580 pixels for a desktop title and 920 for a description, with narrower limits on mobile.
Because the limit is a width and not a character count, a title of narrow letters can fit while a shorter title of wide letters is cut. The result shows the exact snippet, marks the text that would be hidden, and reports the title and description lengths in both pixels and characters. The desktop and mobile views are shown side by side so you can see which one cuts first.
How to read the preview
A missing title or description is reported as a must-fix, because a search engine then writes the snippet from the page itself and you do not control the result. A title or description that exceeds the pixel limit is truncated with an ellipsis, and the tool shows the text that would be hidden. A short title or description is a warning: there is room to say more.
A fitting snippet means only that the title and description fit the estimated width. It does not prove Google will use them. Search engines may rewrite a title or description they judge to be unhelpful or repetitive, and the widths are approximations that vary by device and language. The tool measures the fields as fetched, so a title added by script after load will not appear.
Why truncation matters for search
The visible part of a result is what a searcher reads before deciding whether to click. If the distinguishing words sit at the end of a long title, they are replaced by an ellipsis and cannot help win the click. The same applies to a description whose sentence is cut before it reaches the useful point, because a reader scans only the first line or so.
A page without a meta description often gets a snippet assembled from its body text, which may include navigation or boilerplate rather than a clear summary. Writing a deliberate description keeps that choice in your hands, even though a search engine may still override it for some queries. A description that reads well in the preview is more likely to be kept.
Fix a truncated or missing snippet
Keep the title's key words early, put the brand at the end, and cut filler so the important part survives the cut. For a description, summarise the page in a sentence or two and put the useful part first. Re-run the preview after each edit and check the mobile view, where the limit is narrower, leaving a little slack so a word does not sit on the cut line.
On Shopify and WooCommerce, the title tag and meta description are usually edited per product or set by an SEO plugin; change them there so a theme update does not overwrite them. Then use on-page check to confirm the phrase you care about is in the title and the description. If the plugin renders the tags from product fields, the change applies to every product at once.
When to use related checks
Use meta tag generator to write the tags, and title fixer when several titles need work at once. The generator previews the tags before you paste them, and the title fixer reports which titles are too long across a crawl, so both feed the same pixel measurements used here. One fix can then shorten every page of that type across the whole site.
For guidance on the wording, see the title optimisation guide and the descriptions guide. Use social preview for how the same page appears when it is shared rather than searched, since sharing uses different tags and can look right in one place and wrong in the other. Checking both places is worth the extra minute before you publish, since the two use different tags.
