Google truncates search result snippets by rendered pixel width, not a fixed character count — so a description full of wide letters (M, W) can get cut off sooner than one with the same character count but narrower letters (i, l, t).
This checker estimates your meta description's pixel width, not just its character count, to give a more accurate truncation warning.
How it works
Enter your meta description. The checker counts characters and separately estimates rendered pixel width using a per-character average width table, then compares that estimate against the typical ~920px display budget Google allows before truncating.
- Enter meta description.

Examples
A short, safe description
A 33-character description like "This is a short test description." comes in at roughly 189px — comfortably within the safe display range.
Who should use it
- Checking a new meta description before publishing to avoid unexpected truncation.
- Comparing several draft descriptions to see which fits most safely within the display budget.
Industry applications
- SEO and content marketing
- Web publishing and content management
Advantages
- Estimates pixel width, a more accurate truncation signal than character count alone.
- Reports both the character count and pixel estimate together for full context.
Limitations
- Pixel width is an estimate, not an exact match to every possible font, device, and browser rendering.
Common mistakes to avoid
- Relying on character count alone and assuming any description under 160 characters is automatically safe from truncation.
- Front-loading a description with wide, capitalized words which can push it toward truncation sooner than expected.
Best practices
- Put your most important information in the first ~120 characters, since that's reliably visible even in tighter display scenarios (like mobile search results).
Tips
- This site's SERP Snippet Preview tool shows a full visual mockup of how your title and description will look in search results — pair it with this checker for both a numeric estimate and a visual preview.
