A cover letter should be three to four paragraphs long, totaling less than 400 words and fitting on a single page. That structure gives you enough space to explain why you want the job and what you bring to it, without losing a hiring manager’s attention. Most hiring managers skim cover letters rather than reading every word, so a tight, purposeful structure matters more than length.
The Three-Paragraph Framework
Three paragraphs is the sweet spot for most job applications. Each one has a specific job to do.
Your opening paragraph should explain why you’re writing and why this particular role or company interests you. If someone at the organization referred you, mention their name in the first sentence. This paragraph works best at two to three sentences. Its purpose is to make the reader want to keep going, not to summarize your entire career.
The middle paragraph is where you make your case. Pick two or three experiences that connect directly to skills listed in the job posting, and describe them with enough specificity that the reader understands what you actually did and what resulted from it. This is not the place to restate your resume line by line. Instead, choose the accomplishments that made you think “I can do this job” when you read the posting, and explain them in a way your resume’s bullet points can’t. This paragraph will typically be the longest, running four to six sentences.
Your closing paragraph should be short: a final statement of interest, a brief mention of anything important you haven’t covered, and a thank-you for the reader’s time. Two to three sentences is plenty.
When To Add a Fourth Paragraph
A fourth paragraph makes sense when you have two distinct sets of qualifications worth highlighting separately. For example, if a role asks for both technical skills and leadership experience, you might split those into two body paragraphs rather than cramming both into one. Senior professionals applying for roles that require a broad mix of competencies often benefit from this extra paragraph.
If you go to four paragraphs, keep each one shorter so the overall letter still lands under 400 words and stays on one page. Five paragraphs is the upper limit, and most people don’t need that many.
Adjusting Length for Experience Level
If you’re applying for an entry-level position or one with a straightforward job description, your cover letter can run as short as 200 words. You don’t have a decade of accomplishments to draw from, and padding the letter with filler will be obvious. Three concise paragraphs with specific examples from internships, coursework, or volunteer work will serve you better than four paragraphs of vague enthusiasm.
For mid-career and senior roles, aim closer to 300 words. That length lets you connect your experience to the job requirements without forcing a hiring manager to invest more than a minute or two in reading. Going beyond 400 words rarely helps, regardless of your seniority.
Email vs. Attachment Format
When a job posting asks you to paste your cover letter into the body of an email, lean toward the shorter end: three paragraphs, closer to 200 or 250 words. People read email differently than they read documents, and a wall of text in an inbox feels heavier than the same text in a formatted attachment. When your cover letter is a separate file (PDF or Word document), you have a bit more room to breathe, but one page is still the ceiling.
Making Every Paragraph Count
Hiring managers who do read cover letters tend to skim them quickly, especially during high-volume hiring periods. A compelling opening line or a standout phrase is often what separates a letter that gets attention from one that gets skipped. That means each paragraph needs to earn its place. Before you send, read through each one and ask whether it tells the hiring manager something new, something they wouldn’t already know from your resume. If a paragraph just restates your job titles or offers generic praise for the company, cut it or rewrite it.
White space also helps readability. Keep paragraphs to six sentences or fewer, use a standard font at 10 to 12 points, and set normal margins. A letter that looks dense on the page discourages reading, even if the word count is technically fine.
