How to Write a Cover Letter: Step-by-Step Guide
Last updated October 11, 2026
Short answer: write a cover letter of three or four short paragraphs on one page. Open with the role and a specific reason you are interested, give one or two pieces of evidence that match what the job needs, show you understand the employer, and close with a clear next step. Base every claim on something true and specific to you, and tailor it to each application.
The key idea: a cover letter is not a longer resume. It answers one question: why you, for this job, at this company. Your resume lists the facts; the letter connects them.
Do you need one?
If the application asks for a cover letter, write one. If it is optional, a good one can help, especially when your resume does not make the fit obvious: a career change, a gap, a move across industries, or a role where writing and judgement matter. A weak, generic letter is worse than none, because it adds length without adding signal.
If a recruiter or hiring manager reads it at all, they will probably skim it. Make the first two sentences count.
The structure that works
| Part | Purpose | Length |
|---|---|---|
| Opening | Name the role, state why it interests you in a specific way | 2 to 3 sentences |
| Evidence | One or two achievements that match the job's top requirements | 1 or 2 short paragraphs |
| Fit | Show you understand the employer or team and what you would add | 2 to 3 sentences |
| Close | Thank them, state your interest in talking, keep it simple | 1 to 2 sentences |
Step by step
Step 1: Read the posting and pick two requirements
Highlight what the job needs. Choose the two that matter most, usually the ones mentioned first or repeated. These become the spine of your letter. If you are not sure how to read a posting for priorities, our guide to tailoring a resume to a job description shows a method that works for both documents.
Step 2: Match each requirement to one piece of evidence
For each, choose a single example from your own experience. State what you did and what changed. Include a number only if you have a real one. A short story is fine; a long one belongs in an interview, and the CAR format gives you a compact way to compress it.
Step 3: Add one thing about the employer
Spend ten minutes on the company's site, product, recent announcements or team. Pick one concrete detail and say why it matters to you. Avoid empty praise like "a leader in the industry". Specific interest is credible; flattery is not.
Step 4: Draft the opening last
It is easier to write a strong first paragraph once you know what you will say. State the role and a reason, then promise a payoff: "I am applying for the Operations Analyst role because I enjoy turning messy process data into decisions people act on. Over the last two years I have done exactly that for a regional logistics team." That tells the reader what the letter will show.
Step 5: Write the close
Keep it short and polite. Thank them for considering you and say you would welcome the chance to talk. Do not apologise, do not beg, and do not restate your whole letter.
Step 6: Edit down
Read the draft and remove anything that does not serve the two requirements. Cut sentences that start with "I am writing to". Replace vague words such as "passionate" and "hardworking" with the facts that would justify them. Aim for about 250 to 350 words.
Step 7: Format and proofread
Use a clean, readable font and a simple layout that matches your resume. Check the company name, role title and hiring contact. Read it aloud. Then read it once more from the end to catch typos. Save as a PDF unless the employer asks for another format.
A template you can adapt
Replace everything in brackets with your own, true details.
Dear [Hiring manager name or "Hiring team"],
I am applying for the [role] position at [company]. [One sentence on why this role or the company's work interests you in a specific way.]
In my [current or recent role], I [achievement that matches requirement one, with a concrete outcome]. I also [achievement that matches requirement two]. This is the kind of work the posting describes, and I would bring the same approach to [team or goal].
[One sentence showing you understand something about the employer or team and what you would add.]
Thank you for your time. I would welcome the chance to discuss how I can contribute to [company or team].
Sincerely,
[Your name]
Mistakes that cost you
- Repeating your resume. If the letter lists the same bullets, it has nothing new to say.
- Sending the same letter everywhere. A generic letter with the company name swapped in is easy to spot.
- Starting with yourself. Open with the role and the reason, not a long personal history.
- Overclaiming. Do not state skills or results you cannot support in an interview. You will be asked about them.
- Too long. One page. If a reader must scroll or turn the page, trim.
- Wrong name or role. The most memorable mistake and the easiest to avoid. Check twice.
Using AI to draft one responsibly
An AI tool can give you a first draft quickly, especially if you feed it the posting and your real experience. Treat the output as a starting point. Check every claim against what is true, remove phrases that do not sound like you, and add the specific detail only you know. The cover letter generator works from your resume and a job description, and the cover letter tutorial walks through the steps. Always review before sending; the tool prepares and you decide.
Once the letter is done, make sure your resume tells the same story. The resume tailoring tool and the ATS resume checker help you compare it to the posting, and the resume builder helps with layout.
Three openings, and why the first one wins
The opening is where most letters lose the reader, so it is worth comparing a few approaches side by side. All three below are placeholders; use your own facts.
| Opening | Why it works or fails |
|---|---|
| "I am writing to apply for the Customer Success Manager role. I have spent three years turning unhappy accounts into renewals, and your focus on onboarding is why this team stands out to me." | States the role, shows evidence and a specific reason in two sentences. This is the pattern to copy. |
| "I am a passionate, hardworking professional with excellent communication skills." | Claims qualities without proof. The reader has seen this sentence many times and learns nothing. |
| "My name is Alex and I have always loved technology since I was a child." | Starts with background that has no connection to the job. The reader has to work to find the relevance. |
If you only improve one thing in your letter, improve the first two sentences. Then make sure the rest delivers what they promise.
Special cases: career change, gap, or no experience
A cover letter is the one place where you can explain context that a resume cannot. Use that carefully.
- Career change. Open with the connection between your past work and the new field, and give one example of the skill transferring. The reader should not have to guess why you are applying. Our guide to career change interview tips covers how to tell this story in person as well.
- Employment gap. One honest sentence is enough, followed by what you did or learned. Do not apologise at length, and do not leave it out if the gap is obvious on the resume.
- Early career or no direct experience. Lead with projects, coursework, volunteering or part-time work, and show how you approached the problem and what you produced. See first job interview tips for related preparation.
- Internal move. Keep it shorter, refer to results people there already know, and show how you understand the new team's needs.
A quick quality check before you send
Run through these questions. If any answer is no, edit again.
- Could this letter only have been written for this role and employer?
- Does every claim have a specific example behind it?
- Does it add something that is not on the resume?
- Would I be comfortable discussing each sentence in an interview?
- Is it clear what I want, and is the tone confident and polite?
Frequently asked questions
How long should a cover letter be?
One page, usually about 250 to 350 words across three or four short paragraphs. Shorter is fine if you have said what matters.
Who should I address it to?
Use the hiring manager's name if the posting or LinkedIn shows it. If not, "Dear Hiring Team" is acceptable. Avoid "To whom it may concern".
Should I mention salary in a cover letter?
Only if the application asks for it. Otherwise leave compensation for the interview stage.
Can I reuse a cover letter?
Reuse the structure and the best evidence paragraph, but rewrite the opening and the employer paragraph for each application.
What if I have no direct experience?
Use transferable evidence from projects, study, volunteering or adjacent work. Be honest about the gap and show how you have already started closing it.
