Title & Meta Description Length Checker
Check Title Tag Length
- Use about 60 characters as an editing range
- Rendered width matters more than the character count
- Put the useful words first; narrow results show less text
Check Meta Description Length
- Use about 155 characters as a desktop editing range
- Search engines may replace the description with page text
- Put the useful information first for narrow results
Why Pixel Width Matters
Characters have different widths. "iiiiii" is narrower than "WWWWWW". This tool estimates rendered width to make the character count more useful, but the final search layout can differ.
Are Your Meta Tags Server-Rendered?
Search engines need meta tags in the initial HTML response. Client-side rendered meta tags (added by JavaScript after page load) may not be indexed.
This checker reads the fetched HTML without running client-side JavaScript. Tags shown above were present in that response; search engines may render the page differently.

What is a meta tag checker?
A meta tag checker is a tool that analyzes your page's HTML meta tags including title, description, Open Graph, and Twitter cards. It validates tag length, checks for missing tags, and previews how your page appears in search results and social shares.
What is the ideal title tag length?
About 60 characters is a useful editing range, but search engines measure rendered width and may rewrite the title. Keep the important words early and use the preview as an estimate.
How long should a meta description be?
About 155 characters is a useful editing range for desktop, with less space on many mobile results. Put the useful information first because search engines may truncate or replace the description.
What is the meta robots tag?
The meta robots tag controls how search engines crawl and index your page. Common values include index/noindex (whether to index), follow/nofollow (whether to follow links), and noarchive (prevent cached copy). It's placed in the <head> section.
Why are my meta tags not showing in search results?
Google may rewrite a title or description to better match a query. Make each tag describe the page clearly. If tags are added only after JavaScript runs, confirm that crawlers can see the rendered head.
How do I check my meta description length?
Paste the description into the quick length check to compare its character count and estimated width with common display ranges. The preview is an estimate because search engines can rewrite or truncate descriptions.
What does a title tag checker look for?
This checker reports a missing title, compares its length with a common editing range, and estimates rendered width. It cannot predict a search engine rewrite or find duplicate titles across other pages.
