SEO Meta Tag Length Checker

I built this SEO Meta Tag Length Checker to simplify validating titles and descriptions for multilingual content. It accurately counts mixed full-width (i.e. Japanese or Chinese characters) and half-width (i.e. English alphabets or numbers) characters, instantly ensuring your tags meet SEO best practices.

How To Use This Tool

Enter your meta title or description into the input fields above. The tool instantly displays the full-width character count, along with visual feedback to indicate whether your text meets the recommended length.

Alternative Methods to Check SEO Meta Tag Length

  1. LENB function in Excel (not LEN).
    LENB counts the byte length of text in cells. Alphanumeric characters are single byte, and full width Japanese characters are double bytes. The recommended maximum LENB for Japanese SEO titles is 60, and meta description is 135.

  2. This Google Apps Script checks each character’s Unicode range to determine if it’s full-width or half-width. Type your title or meta description in Google Sheets, and use the TITLE_LENGTH function to get the total length in full-width characters.

  3. Enter your title tag, meta description, and URL into Portent’s Google SERP Preview Tool to see how they’ll appear in a Google search result.
