About This Meta Description Length Checker
What This Tool Checks
This tool measures the character count and actual pixel width of your title tag and meta description in real time as you type — using the HTML Canvas API with the exact Arial font sizes Google uses in search results. It gives you a true readout of whether your text will fit Google's display limits, not just an approximate character count.
- Title tag character count — with color-coded bar (green: 50–60, amber: too short, red: over 60)
- Title pixel width — measured in Arial 20px; Google's hard limit is 600px on desktop
- Meta description character count — ideal range 150–160 chars; mobile stricter at ~130
- Meta description pixel width — measured in Arial 14px; Google's hard limit is 920px
- Focus keyword presence — detects keyword in title, description, and near the beginning
- URL format check — validates HTTPS scheme for the SERP breadcrumb
- One-click HTML snippet — copies title, description, keywords, robots, OG, and Twitter Card tags
How to Use This Tool
- Type or paste your title tag — the bar turns green when you're in the 50–60 character optimal range
- Type or paste your meta description — aim for 150–160 characters; the bar turns red if you exceed 160 characters or 920px
- Enter your focus keyword to instantly see if it appears in both title and description and how early in the text it occurs
- Click Load Sample to populate all fields with a well-optimised example and explore all features
- Switch to the SERP Preview tab to see exactly how your snippet appears on Google desktop, mobile, and dark mode

- Click Copy HTML Tags to get ready-to-paste title, description, robots, Open Graph, and Twitter Card markup
Title Tags & Meta Descriptions — SEO Reference Guide
Characters vs. Pixels
Google measures snippets in pixels, not characters. Because Arial is a proportionally-spaced font, "W" is much wider than "i". A 60-character title made of narrow letters may fit in 400px; a 52-character title with many wide letters may overflow 600px. This tool uses Canvas API measurement with exact Google fonts — making it more accurate than any character-only checker.
Limits at a Glance
| Element | Chars | Pixels |
|---|---|---|
| Title (desktop) | 50–60 | ≤600px |
| Title (mobile) | 50–60 | ≤580px |
| Description (desktop) | 150–160 | ≤920px |
| Description (mobile) | ≤130 | ≤680px |
CTR & Rankings
Meta descriptions are not a direct ranking signal — Google has confirmed this. However, a well-written description that matches search intent increases click-through rate (CTR). Higher CTR from relevant queries sends positive engagement signals. When your keyword is in the description, Google bolds it in the snippet, making your listing more prominent and visually distinct from competitors.
Google Rewrites
Google rewrites approximately 70% of meta descriptions. It substitutes a passage from the page body when the query intent doesn't match the written description. Pages with accurate, keyword-rich descriptions that mirror the page's actual content are rewritten less often. Writing a strong description still matters — it also controls your Open Graph snippet on social platforms, which Google does not rewrite.
