Check your meta description in characters and real pixels — measured with the same font Google uses in search results — and see exactly where it gets cut off on desktop and mobile. Add your focus keyword to see it bolded the way Google bolds matching query terms. 100% in your browser — nothing is uploaded or stored.

The Meta Description Length Checker tells you whether the grey snippet text under your search result will display in full or trail off mid-sentence. The meta description is your free ad copy on Google — it does not directly affect rankings, but it heavily affects whether a searcher clicks your result. Like titles, descriptions are truncated by pixel width, not character count, so this tool measures your text in real pixels using Google's result-page font, previews the exact cut-off on desktop and mobile, and bolds your focus keyword in the preview the same way Google bolds matching query terms. A bulk mode grades whole lists of descriptions in one click.
It is part of the SERP & Content Analysis group in our free SEO Toolkit. Pair it with the Title Tag Length Checker to size the blue line above, the SERP Snippet Preview to see the complete result together, the Meta Tag Analyzer to audit an existing page's tags, and the Meta Tag Generator to produce the final markup. Everything runs in your browser — your descriptions are never uploaded or stored.

A meta description length checker tells you whether the descriptive text under your search result will display in full or be cut off with an ellipsis. The meta description is effectively the ad copy of your search listing: Google has confirmed it is not a direct ranking factor, but it is one of the strongest influences on click-through rate — the difference between a searcher choosing your result or scrolling past it. A description that gets chopped mid-promise loses its persuasive power at the worst possible moment. This tool measures your text the way Google evaluates it and previews the result before you publish. It is part of the SERP & Content Analysis group in the SEO Toolkit.
Like title tags, descriptions are truncated by pixel width, not character count — Google allows roughly 990 pixels of description text on desktop, which usually works out to about 150–160 characters, and noticeably less on mobile, often closer to 120 characters. Because letters vary in width, two descriptions of identical length can be cut at different points. And because mobile cuts so much earlier, your most important message and call to action need to live in the first 120 characters, where they survive on every device.
Measured with the Canvas API in Google's snippet font, not estimated.
Mobile shows roughly a quarter less text — front-load what matters.
Google bolds query terms in snippets — the preview shows this live.
A complete, benefit-led snippet earns more clicks than a chopped one.
Aim for 120–160 characters, keeping the pixel meter under about 940px for a safe margin below Google’s ~990px desktop cut-off. Lead with the benefit and the focus keyword — Google bolds terms that match the search query, and bold words draw the eye, so a naturally placed keyword makes your snippet visually stand out. Put the call to action before the 120-character mark so mobile users see it too. Write a unique description for every page: duplicated descriptions are one of the most common reasons Google ignores yours and generates its own snippet from page content instead. Honest, specific copy that matches the page beats vague superlatives every time.
The tool draws your description onto an invisible HTML canvas using the Arial typeface at the size Google renders snippet text, then reads the rendered width with the Canvas measureText API. The total is compared against Google's approximate desktop and mobile budgets, which reflects how wide and narrow letters really differ — something character counting cannot capture.
No — Google adjusts its layout periodically, snippet length varies by query, and fonts render slightly differently across devices. The limits here are well-established approximations used by professional SERP tools. That is why the checker treats 940px as the safe zone rather than promising one immovable number, and why front-loading your message is always the robust strategy.
Google rewrites a large share of descriptions when it believes a passage from the page answers the query better — especially when the description is duplicated across pages, vague, or unrelated to the search. A unique, specific, well-sized description that genuinely summarises the page is the most likely to be shown as written.
No. Measurement, the preview, keyword bolding and bulk grading all run entirely in your browser with JavaScript, and the tool never makes a network request with your text. Nothing you type is uploaded, logged or stored, so it is safe for unreleased pages and confidential client work.
Size and sharpen every description before it ships.
Bulk-check descriptions exported from a site crawl in one pass.
Rewrite weak snippets on pages that rank but rarely get clicked.
Fit product benefit, offer and call to action into the visible width.
Use the Meta Description Length Checker with these tools from the SEO Toolkit: size the blue line with the Title Tag Length Checker, view the complete result with the SERP Snippet Preview, audit a live page's tags with the Meta Tag Analyzer, generate final markup with the Meta Tag Generator, check keyword balance in the page itself with the Keyword Density Analyzer, keep snippets unique with the Duplicate Content Checker, and check how rich results change your listing with the Rich Result Preview.

Everything about meta description length.
It measures your meta description in both characters and true pixel width, using the same font Google renders in search snippets, and shows a live preview with the exact cut-off point on desktop and mobile. Your focus keyword is bolded the way Google bolds matching query terms, and a bulk mode grades whole lists at once.
Yes, completely. There is no cost, no sign-up and no limit on how many descriptions you check, individually or in bulk. The tool runs entirely in your browser, so there are no server costs and nothing to pay for.
Aim for 120 to 160 characters, staying under roughly 940 pixels for a safe margin below Google’s approximately 990px desktop cut-off. Because mobile shows noticeably less — often around 120 characters — put your key message and call to action in the first 120 characters so they survive on every device.
Google truncates snippets at a pixel budget, and letters vary in width — wide capitals consume far more space than narrow lowercase letters. Two descriptions of identical character count can be cut at different points, so measuring real rendered pixels is the only reliable way to predict where the ellipsis lands.
Not directly — Google has confirmed the meta description is not a ranking factor. It is, however, one of the strongest influences on click-through rate, because it is the sales copy of your listing. More compelling, complete snippets earn more clicks from the same ranking position, which is why sizing them properly matters.
Google bolds words in the snippet that match the searcher's query, and bold text draws the eye on a results page. The preview reproduces this so you can see how prominent your description looks for its target search, and the tool flags the keyword if it is missing so you can work it in naturally.
No. Measurement, the preview, keyword bolding and bulk grading all run entirely in your browser with JavaScript, and the tool never sends your text over the network. Nothing you type is uploaded, logged or stored, so it is safe for unreleased pages and client work.
Google cuts it at the pixel limit and appends an ellipsis, which can swallow your call to action or the second half of your promise. The preview shows exactly which words survive on desktop and mobile, so you can trim and front-load the message before publishing rather than discovering the cut in live results.
Google rewrites a large share of descriptions when it believes a passage from the page answers the query better — particularly when the description is duplicated across pages, vague or unrelated to the search. A unique, specific, well-sized description that honestly summarises the page is the most likely to appear as written.
