Search results have a fixed visual width. Since letters vary in width (an 'i' vs a 'W'), measuring by rendered pixels keeps the visual line length consistent regardless of which letters are used — a fixed character count can't do that.

Why Character Counts Lie
Google truncates search snippets by pixel width, not character count — which is why two titles with the same number of characters can be cut off at completely different points. A title full of narrow letters like "i" and "l" fits far more characters before truncation than one full of wide letters like "W" and "M". Most "SEO preview" tools just count characters, which gives a misleading result.
This tool measures actual rendered pixel width using the same font Google renders search results in, so the truncation point you see here matches what really happens in search results — for both desktop and mobile layouts, which use different width limits.
How It Works
1. Enter Your Details
Site name, URL, page title, and meta description.
2. Watch It Update Live
The preview and pixel-width bars update as you type.
3. Check Both Devices
Toggle between desktop and mobile — the limits differ.
4. Adjust & Perfect
Trim until the bar turns green with no truncation.
Writing Tips
Getting the Most from 600 Pixels
| Element | Desktop Limit | Mobile Limit | Tip |
|---|---|---|---|
| Title Tag | ~600px (~55–60 chars) | ~460px (~40–45 chars) | Put your primary keyword and brand name early — mobile cuts off sooner. |
| Meta Description | ~920px (~155–160 chars) | ~680px (~120 chars) | Front-load the value proposition; the ending is more likely to be cut on mobile. |
Write for the Truncation Point
Assume the description gets cut mid-sentence on mobile. Structure it so the first ~100 characters alone still make sense and sell the click.
Avoid Duplicate Titles
If every page on your site starts with the same phrase, you waste your limited pixel budget on repetition instead of unique, compelling copy.
Google May Rewrite It Anyway
Google frequently generates its own snippet from on-page content if it thinks that better answers the query — a well-written page, not just a well-written tag, is still the foundation.

Why does Google truncate by pixel width instead of character count?
Will Google always show exactly what I write?
Not always — Google often generates its own title or description from on-page content if it better matches the query. A good tag makes it more likely to be used as-is, but isn't a guarantee.
Is my content uploaded anywhere?
No. All measurement and preview rendering happens entirely in your browser. Nothing is sent to any server.
