SERP Snippet Preview

Content

Preview your title tag and meta description exactly as Google renders them. Pixel-accurate truncation warnings for both desktop and mobile — so you fix issues before you publish.

How to use this tool

Enter your title tag, meta description, and the URL as it will actually appear, then watch the live preview switch between desktop and mobile rendering. The pixel ruler underneath each field is doing the same width calculation Google's rendering engine does — it's measuring actual character widths in the font Google uses, not just counting characters, which is why two titles of the same character count can truncate differently.

The single most common mistake this tool catches: a title that looks fine at 58 characters on desktop but truncates mid-word on mobile, because the mobile SERP container is narrower. Fix the title so the most important keyword and your brand name both land before the truncation point on the narrower of the two views, and the desktop view will almost always be fine as a result.

For the meta description, remember Google rewrites it automatically when it judges your text doesn't answer the query as well as a snippet it can pull from the page body. Writing a description that states the page's answer directly and concisely — rather than a vague teaser — reduces how often Google overrides it.

Once your title and description are dialed in here, the Slug Generator is the natural next step — keeping the URL slug aligned with the title you just finalized reinforces the same topical signal across all three SERP elements.

Get the pixel width wrong and Google rewrites it. Get the message wrong and users scroll past. Here is the formula that works.

Frequently asked questions3

QHow does Google truncate title tags?

Google truncates title tags at roughly 600px using Arial font (about 55–60 characters for typical text). This tool measures your title in pixels, the same way Google does, and shows exactly where it cuts off.

QHow long should a meta description be?

Meta descriptions are truncated at approximately 960px on desktop and ~540px on mobile. Aim for 140–160 characters. Descriptions that fit within pixel limits are less likely to be rewritten by Google.

QDoes Google always use my meta description?

No. Google rewrites descriptions when it judges that its own snippet better matches the search query. The best defence is writing a concise, answer-first description that directly states what the page is about.

How Google truncates titles and descriptions

Google measures title tags in pixels, not characters. Search result pages render titles using a proportional-width font (Arial), meaning wider characters likeW take far more space than narrow ones likei orl. A title of 55 characters may fit perfectly or be cut off depending entirely on which characters it contains. This tool measures your title and description using the same pixel-width method Google uses — so what you see here is exactly what Google will render in search results.

Meta descriptions are also measured in pixels,with a limit around 960px on desktop (roughly 155–160 characters of typical mixed text) and around 540px on mobile. Google frequently rewrites meta descriptions when it judges that its own snippet better matches the user's search query. Writing a tight, direct answer in the first sentence significantly reduces how often Google overrides your description — because a front-loaded, answer-first description is already doing exactly what Google would prefer to show.

CTR (click-through rate) is one of the strongest signals Google uses to confirm ranking decisions. A higher CTR from search results tells Google that your listing matched what searchers wanted, which can reinforce or even improve your ranking position over time. The title tag and meta description are the only two elements of your page that users evaluate before deciding to click — investing time in these two fields is one of the highest-ROI SEO activities available.
