文字数カウンターとは？
The Character Counter instantly counts characters, words, sentences, and paragraphs as you type or paste text. It's an essential tool for writers, students, social media managers, and anyone who needs to meet specific text length requirements. Many platforms enforce character limits — Twitter/X (280 characters), Instagram captions (2,200), meta descriptions (155-160), SMS messages (160), and academic abstracts (150-300 words). Exceeding these limits means your content gets cut off or rejected. This tool provides real-time counting with detailed breakdowns including characters with and without spaces, word count, average word length, sentence count, and estimated reading time. It's useful for everything from crafting tweets to writing essays and SEO meta descriptions.

▶What's the difference between characters with and without spaces?
Characters with spaces counts every character including space bar presses. Characters without spaces counts only letters, numbers, and punctuation. Different platforms use different counting methods — Twitter counts with spaces, while some SMS systems count without.

Key limits: Twitter/X posts (280 chars), SMS (160 chars), Google meta title (60 chars), meta description (155-160 chars), Instagram bio (150 chars), Instagram caption (2,200 chars), LinkedIn headline (220 chars), and YouTube title (100 chars).
