How are bytes calculated?

Bytes are calculated using UTF-8 encoding. English letters use 1 byte each, while Korean characters (한글) use 3 bytes each. This matters for systems with byte-based limits.

What is the Twitter/X character limit?

Twitter (now X) allows up to 280 characters per tweet for free accounts. This includes all characters, spaces, and emojis. URLs are shortened to 23 characters.

How is reading time estimated?

Reading time is estimated at approximately 200 words per minute for English text, which is the average adult reading speed.

📖 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.
