Mobile allows roughly two title lines (~920px total) but a shorter description. Both previews use Google's light theme.
Type a title, description, and URL and the tool renders Google-style desktop and mobile result cards live. Under the inputs, pixel meters measure your text with the browser's canvas API at Google's font sizes (Arial 20px for titles, 14px for descriptions) and compare it to the truncation limits: ~580px for desktop titles and ~990px for desktop descriptions, with a tighter mobile budget. Go over and you get a red warning plus an ellipsis in the preview — before Google adds one for real.
The star-rating toggle adds a realistic rating row (stars, score, review count) under the title, so you can compare your plain snippet against the rich result version competitors with review schema are showing.
Your snippet is your ad in the organic results. A truncated title loses its call to action mid-sentence; a truncated description hides the pricing or proof point you buried at the end. Writing to the pixel budget — key message first, brand last — measurably improves click-through without touching your rankings.
Review stars amplify that further: they add color, height, and social proof to your result. But they can't be faked in a preview tool — Google only shows them when it finds valid AggregateRating markup backed by real reviews. Build that markup with the schema generator, verify it with the validator, and pair it with well-crafted meta tags.
Google truncates by pixel width, not characters — roughly 580px on desktop, which is about 50–60 characters depending on letter widths (a 'W' is three times wider than an 'i'). This tool measures your actual text at Arial 20px, the same approximation SEO crawlers use.
About 990px on desktop (roughly 155–160 characters over two lines) and less on mobile. Google also frequently rewrites descriptions, so treat yours as a strong suggestion: front-load the value proposition in the first ~120 characters.
Stars come from AggregateRating structured data on your page — typically nested in a Product, SoftwareApplication, or LocalBusiness entity — backed by real, visible reviews. Toggle 'Show review stars' in the preview to see the effect, and use our JSON-LD generator to build the markup.
It's a close approximation. We measure with canvas measureText using Arial at 20px (titles) and 14px (descriptions), which mirrors Google's rendering closely but not perfectly — Google's exact font stack, DPI handling, and limits shift over time. Stay comfortably under the limit rather than at it.
