📖 Writing Tips & Character Limits Guide
Social media best practices: Each platform has its own character limits and optimal post lengths. Twitter/X allows 280 characters, but tweets between 71-100 characters get the most engagement. Instagram captions can be up to 2,200 characters, but only the first 125 show before "more."
YouTube titles: Keep titles under 60 characters to avoid truncation in search results. The maximum is 100 characters, but shorter, keyword-rich titles perform better.
Understanding bytes vs characters: A single English letter takes 1 byte in UTF-8. Korean characters (한글) take 3 bytes, and emojis can take up to 4 bytes. This matters for databases and APIs with byte limits rather than character limits.
Readability tips: Aim for 15-20 words per sentence for clear, readable prose. Use short paragraphs (2-3 sentences) for digital content. The average adult reads at about 200 words per minute in English.
