Google SERP Preview Tool
See how your title, description and URL may look in Google results on desktop and mobile, measured in pixels. A simulation, so you can avoid cut-off text.
Your snippet
Type or paste your title, description and URL. The preview updates as you type. Nothing is uploaded.
Import from page HTML
Live preview
A simulation of Google results. Google can show something different.
Widths are measured in Arial, the font Google uses for results. The pixel limits are common approximations: Google does not publish exact limits and they vary by device and query.

What fails a SERP snippet preview
| Mistake | What happens |
|---|---|
| Assuming the live result will match the preview | Google may rewrite titles and descriptions. The preview shows what you supplied, not what Google decides. |
| Counting characters instead of pixels | A title of capitals or wide letters is cut sooner than one of the same length in narrow letters. |
| Checking only desktop | Mobile results are narrower, so the end of the snippet is cut sooner. |
| Previewing a URL you have not published | The preview cannot fetch your page. It only shows the text and URL you type. |
| Stuffing the title to use all the width | A full width is not a ranking benefit, and repeated keywords can make Google rewrite the title. |
| Putting the brand or city at the end of a long title | The part that gets cut is often the part that mattered most. |
Before you trust the preview
- You checked both the desktop and the mobile preview.
- You put the most important words at the start of the title and description.
- You used the test search box to see which words Google may bold.
- You remember that Google can replace your title or description.
- You copied the final tags into the page and re-checked the live result later in Google.
What a good result should show
Title Emergency Plumber in Austin, TX | Example Plumbing Co., a 100-character description, and a URL such as https://www.example.com/services/emergency-plumber/.
A desktop and mobile result with the URL as a breadcrumb, green width bars for the title and description, and no warnings. If you paste a much longer title, the preview shows where it would be cut and the bar turns red. Press Load example to try it.
A simulation, not Google's output
The tool measures your text in Arial and compares it with commonly used width approximations. Google publishes no official limits, may change how results look, and often writes its own title or snippet. Treat the preview as a guide for avoiding obvious cut-offs.
How the preview is built
- Measure the text. Your title and description are measured in pixels with your browser, using Arial at 20px for the title and 14px for the description.
- Compare with approximate limits. About 600px for a desktop title and 920px for a desktop description. About 540px and 680px for mobile.
- Cut at a word boundary. If the text is wider than the limit, words are removed from the end until it fits with an ellipsis, as the preview does for Google results.
- Build the URL line. The address becomes a breadcrumb with the path split by "›", and the site name or domain is shown above the title.
- Run the checks. The tool flags width, very short text, all capitals, repeated words, a duplicated description, http URLs and capital letters in the URL.
Reading the width bars
| Bar | Meaning |
|---|---|
| Green | The text fits inside the approximate limit with a little room to spare. |
| Amber | It fits, but only just. A different font rendering or a bolded word could push it over. |
| Red | It is wider than the approximation, so the end would probably be replaced by an ellipsis. |
A red bar is not an error. Google keeps and may still use the full text. It simply means readers may not see the end, so the important words should come first.
Limits worth knowing
- Google's real result can differ: it may rewrite titles, pick other page text for the snippet, and add dates, site names, ratings or sitelinks.
- The pixel limits are approximations from public testing and change over time. Real Arial rendering also varies slightly by device.
- The tool does not fetch live pages or query Google. It previews only what you enter, or import from HTML you paste.

Is this exactly how Google will show my result?
No. It is a simulation. Google may rewrite your title, choose a different snippet from the page, and change the layout. Use it to avoid obvious cut-offs, then check the real result in Google after the page is indexed.
What are the title and description limits?
Google publishes none. The widely used approximations are about 600 pixels for a desktop title and 920 pixels for a desktop description, with narrower limits on mobile. This tool uses those approximations and says so.
Why pixels and not characters?
Results are laid out in pixels, so wide letters use more room than narrow ones. Two titles with the same number of characters can fit differently. The character count is shown only for reference.
Why did Google show a different title from mine?
Google may build the title from your page headings, other text or links when it thinks that describes the page better, or when a title is too long, repetitive or generic. A clear, accurate, reasonably short title is least likely to be replaced.
What does the test search box do?
Google bolds words from the searcher's query inside snippets. Typing a query here bolds matching words so you can see how your text may look for that search.
Can I import my existing title and description?
Yes. Paste your page's HTML in the import box and the tool reads the title, meta description and canonical URL. It does not fetch pages on its own.
Does a longer description help rankings?
No. The meta description is not a ranking factor, and Google may ignore it. Its value is to make an accurate, appealing summary that earns the click.
