Character Counter

Character limits govern communication across every digital platform. Twitter/X allows 280 characters (formerly 140), Instagram captions max at 2,200, LinkedIn posts at 3,000, and meta descriptions should stay under 160 for optimal Google display. SMS messages are limited to 160 characters in GSM encoding, but each message beyond that splits into 153-character segments (7 characters used for concatenation headers), meaning a 161-character message actually uses two SMS credits. Email subject lines display fully at about 50-60 characters on desktop and 30-35 on mobile — anything longer gets truncated with an ellipsis. This counter shows total characters, characters without spaces, word count, sentence count, paragraph count, and reading time simultaneously. It distinguishes between bytes and characters — important for databases where VARCHAR(255) means 255 bytes, not 255 characters. A single emoji can use 4 bytes, and Chinese/Japanese/Korean characters use 3 bytes in UTF-8. All counting runs locally in your browser with no text transmitted anywhere.

Each platform has an optimal content length that maximizes engagement. Blog posts perform best at 1,500-2,500 words for SEO, with the top-ranking content on Google averaging 1,890 words. However, the ideal length depends on topic complexity — a recipe might need 800 words while a comprehensive guide warrants 4,000+. Social media sweet spots differ: Facebook posts get the most engagement at 40-80 characters, LinkedIn articles perform best at 1,900-2,000 words, and Instagram captions see the highest engagement when they are either very short (under 125 characters for simple posts) or very long (2,000+ characters for storytelling posts). For ad copy, Google Ads headlines allow 30 characters per headline (up to 3) and 90 characters per description (up to 2). Amazon product titles should be under 200 characters with brand, product line, material, key feature, size, and color. Use this counter to draft platform-specific content and verify you are within limits before posting.
