or when the user asks to skip, go directly to the main output.
Scope (On-Page SEO)
Meta description
CTA; unique value; target keyword; unique per page
Length by Language
Google truncates by
pixel width
(~920px desktop, ~680px mobile), not character count. Character limits are approximate—CJK chars are wider (~2× Latin), so fewer fit in the same pixels.
Script / Language
Meta description (chars)
Notes
Latin
(English, Spanish, French, etc.)
150–160
Desktop ~158; mobile ~120
CJK
(Chinese, Japanese, Korean)
75–100
Full-width chars; 70–80 conservative; 90–100 on some locales/fonts; use pixel checker when available
Cyrillic
(Russian, etc.)
140–155
Slightly wider than Latin
Arabic, Hebrew
70–90
RTL; variable width
Pixel tools
Use a pixel-accurate meta tag checker for CJK—font and locale affect display; character counts vary by source (65–80 to 90–120 in practice).
Multilingual
Use locale-specific limits; localize, don't just translate. See
localization-strategy
,
translation
.
Initial Assessment

exists, read it for brand voice and target keywords.
Identify:
Page type
Homepage, landing, blog, product, etc.
Primary keyword
Target search query
Language / script
Apply length rule above
CTA
Primary action (sign up, learn more, buy, etc.)
Best Practices
Item
Guideline
Length

Recommended meta description
(with character count for target language)
