How long should a cover letter be? The answer, then every case

A cover letter should be long enough to connect your experience to the job, and short enough to read in under a minute. In practice, that means the targets below. Words are the easiest to check in any word processor; the page limit is the one hiring managers notice.

CareerOneStop, run by the U.S. Department of Labor, puts it simply: cover letters don't need to be long, and a good one can be about 200 to 400 words, with just three to four short paragraphs. Most career sites land on the same range, with 250 to 400 words as the sweet spot.

The surest way to hit the right cover letter length is to give each paragraph a word budget before you write. A four-paragraph letter of about 320 words breaks down like this:

1. Opening, 50 to 70 words. The job title, where you saw the posting, and one sentence on why this company or role caught your attention.
2. What you bring, 90 to 120 words. The two skills the posting asks for most, each proven by one fact from your experience, with a number if you have one.
3. Why them, 60 to 90 words. Something specific you learned about the employer and how it connects to what you want to do.
4. Closing, 30 to 50 words. A thank-you, your availability, and a line that asks for a conversation.

This fictional letter for a customer success role has a body of about 260 words; with the header, greeting and sign-off, the page holds about 300. It fits on one page with room to spare. For a letter written from scratch for a student, see our internship cover letter.

Re: Customer Success Manager (ref. CS-2611)

Dear Ms. Brooks,

Your Customer Success Manager posting asks for someone who can turn renewals around in the mid-market segment. That is exactly what I have spent the last three years doing at Fieldstone Analytics, a reporting platform for regional retailers, and I would like to bring the same approach to Lakeshore's growing scheduling product.

At Fieldstone, I manage 60 accounts worth $2.4 million in annual revenue. When I took over the portfolio, our renewal rate was 81%. By setting up quarterly business reviews and a 90-day onboarding plan for every new client, I brought it to 93% within a year. I also built the health-score dashboard our team now uses to spot at-risk accounts two months before renewal, and I trained four new managers to use it. Your posting mentions Salesforce and Gainsight: I use both every day.

Lakeshore stands out to me because your customers are clinics and small practices, the same kind of busy, small teams I support today. They rarely have time for long training sessions, so I have learned to keep every call short and every follow-up specific. I read about your new self-service onboarding and would love to help pair it with hands-on support for the accounts that need it most.

My resume is attached with more detail on my results. I would welcome the chance to discuss how I could help your team grow renewals this year, and I am available for a call any weekday. If it helps, I can share the onboarding plan I built, with client names removed. Thank you for your time and consideration.

Sincerely,

Jordan Ellis

The one-page limit doesn't move. What changes with your situation is the cover letter length inside the 250-to-400-word range, and how many paragraphs you need.

• Internship or entry-level job: 200 to 300 words. You have fewer experiences to cite, so three paragraphs are enough. Use class projects, part-time work or volunteering as proof, never a list of adjectives.
• Mid-career: 300 to 350 words. Four paragraphs, with your two strongest results in the middle.
• Senior or executive role: 350 to 400 words. More experience means more to choose from, not more to say. Pick two or three wins and leave the rest for the interview.
• Career change: up to 400 words. Use the extra paragraph to show which skills carry over and what you've already done to make the switch.
• Email cover letter: 150 to 250 words. When the email itself is your cover letter, keep it to three short paragraphs. If you attach a separate letter, the email is just two or three lines.
• Online form or text box: the stated limit. Some application forms cap the cover letter field at a set number of characters. Write in a document first, check the count, then paste.
• The posting gives a word count or questions: follow it exactly. An instruction in the posting beats every guideline on this page.

Many employers don't ask for a cover letter at all, CareerOneStop notes. When the field is optional, a short letter of 200 to 250 words is still worth sending if you can name the company and give one specific reason you fit.

• It goes past one page, or you shrank the font or the margins to keep it on one.
• It retells your resume job by job, in the same order.
• A paragraph runs longer than six lines on the page.
• It lists five or more skills. Two or three, each with proof, are more convincing.
• It opens with a sentence about the letter itself: “I am writing this letter to express my interest in...”

Then cut what the reader doesn't need: duties without results, years of experience they can see on your resume, and phrases like “I believe” or “I feel.” Keep your proudest numbers, drop the rest.

Yes. Below about 150 words, a letter rarely says anything the resume doesn't, and it reads like a form letter sent to fifty companies. A two-sentence note that says “Please see my attached resume” isn't a cover letter. If yours is short, check that it names the company in the body, cites at least one fact with a number, and explains why you want this particular job.

• A readable font at 10.5 to 12 points. Use the same font as your resume, so the two look like one application.
• Margins of about 1 inch. Shrinking them to fit more text is the first thing a hiring manager notices.
• Single spacing, with a blank line between paragraphs. White space makes a 350-word letter look easy to read.
• Left-aligned text. Justified text creates uneven gaps between words.
• PDF, unless the posting asks for something else. A PDF keeps your page break exactly where you put it.

Kandiq's cover letter generator writes a first draft from the job posting and your resume, in three to four paragraphs grounded in facts from your experience (2 AI credits per letter, 5 credits when you sign up). The review then checks the length without any AI: it counts the characters in the body, flags anything under 900 or over 2,600, the point where a letter spills onto a second page, and counts your paragraphs, aiming for three to five.

If the draft is still too long, the “Shorter” rewrite tightens it for 1 credit, and you can edit every sentence by hand. You read the full letter and its review before paying anything; downloading the PDF is part of Kandiq Pro.
