*Google has no officially published character or pixel limit. These are the widely-observed soft caps - ~600px / ~60 characters for titles, ~920px / ~155 characters for descriptions.
A SERP snippet checker (or SERP preview tool) shows how your page will appear in Google results before you publish: your meta title and description rendered exactly as searchers see them, on desktop and mobile. It doubles as a title checker, a meta description checker, and a length tester in one.
Title tags and meta descriptions don't move rankings on their own, but they decide whether anyone clicks. Use this checker to sanity-check your snippet before you publish - if your title runs past ~600 pixels or your description past ~920 pixels, Google will cut it off mid-sentence or rewrite it. Keep it tight, put the keyword near the front, and give the searcher a clear reason to click.
Google truncates titles by pixel width, not character count: the widely-observed cap is ~600px on desktop. A title full of wide letters gets cut sooner than one of the same character length. That is why this SERP length checker measures pixels first and characters second. And SERP pixel height? A snippet's height only grows when your title wraps to a second line on mobile, so if you keep the width under the cap, the height takes care of itself.
Often, yes. Studies consistently find Google rewrites well over half of title tags. The usual triggers: titles past ~600px, the query keyword missing, or boilerplate patterns. Use this checker as a Google title rewrite checker: if your title is over-length or keyword-thin for its target query, expect Google to swap in its own version, and fix it before it does.

Paste the title, URL and description above. The preview shows the snippet on desktop and mobile with live pixel and character counts, and flags anything Google is likely to cut or rewrite.
Keep titles under roughly 600 pixels and descriptions under roughly 920 pixels. Google has no official published limit; these are the widely-observed caps before truncation.
No. Featured snippets are pulled from your page content, not your meta tags, so no meta checker can test them. This tool tests the standard result snippet: your title and description.
No, it does not check positions. It is a snippet preview and tester: how your result looks once it ranks. For position data, use Google Search Console.
