# Word & Character Counter

Count words, characters, sentences, paragraphs, and estimated reading time. Compare against Twitter/X, SMS, Instagram, LinkedIn limits. Shows UK SMS vs US SMS differences.

## Quick answer

Standard SMS uses GSM-7 encoding (7-bit), allowing 160 characters per message. When you include emoji, accented characters, or non-Latin scripts, the message switches to UTF-16 (16-bit UCS-2) encoding. This reduces the single-message limit from 160 to 70 characters. This applies worldwide — it's a technical SMS protocol limitation, not a UK-specific rule. Ofcom in the UK explicitly notes this distinction in consumer guidance.

There is no universal ideal length. Google's John Mueller has confirmed word count alone is not a ranking factor. However, comprehensive content tends to rank better because it covers more related queries. Common practical guidance: short posts 300–600 words, standard posts 800–1,200 words, long-form articles 1,500–2,500 words. UK content agencies typically target 1,200–1,800 words for standard SEO articles; US practices are similar.
