Letter length matters more than you think. Hiring managers spend an average of just 7 seconds scanning a cover letter before deciding whether to keep reading. A letter that's too long gets skimmed; one that's too short looks unprofessional. Paste your letter below and get instant feedback on word count, reading time, and whether your letter hits the sweet spot for its type.
The ideal cover letter length is 250 to 400 words — roughly three to four short paragraphs that fit on a single page. This gives you enough space to introduce yourself, highlight your most relevant experience, and explain why you're a strong fit for the role. Anything over 500 words risks being skimmed or skipped entirely, since recruiters review hundreds of applications. Focus on quality over quantity: every sentence should earn its place.

A resignation letter should be 150 to 300 words — short, direct, and professional. Include your intent to resign, your last working day, a brief expression of gratitude, and an offer to help with the transition. There's no need for lengthy explanations or emotional narratives. Keeping it concise shows respect for your employer's time and leaves a positive final impression. A well-structured resignation letter takes under a minute to read. Create a professional resignation letter in seconds.
The length of your letter signals professionalism and awareness of your audience. In professional contexts, readers are busy — they want the key information fast. A cover letter that runs two pages tells a hiring manager you can't prioritize. A complaint letter that's only two sentences suggests you're not serious. Getting the length right shows you understand the format, respect the reader's time, and can communicate effectively. Use the checker above to find your sweet spot, then let LetterCraft AI generate professional letters optimized for length, tone, and impact.
