How to write a cover letter: Steps, format, and example

Most cover letters fail because they repeat the resume instead of explaining it.

A strong one runs to three or four short paragraphs, names one achievement with a measurable result, and connects that result to what the employer actually needs.

Write a cover letter in five steps: build the header, open with your strongest relevant claim, prove it with one quantified achievement, explain why this employer specifically, and close by asking for the interview.

The order matters because the opening lines decide whether a reader continues.

Put your name, phone number, email, and city at the top of the page, matching your resume exactly.

A header that differs from your resume is the first sign the two documents were assembled separately rather than prepared together.

Address a named person wherever you can find one, checking the job posting, the company website, and LinkedIn before falling back to a team or department.

Name the role you are applying for, then state the single most relevant thing about you in the same breath.

Skip “I am writing to apply for,” which spends your first line on information the reader already has.

Lead instead with the experience that makes the rest of the letter worth reading.

Pick one achievement that maps directly to the job posting and build it with context, action, and result.

Coaches at Careerminds see the same failure across thousands of participants: people describe the job they held rather than the result they produced.

“Managed the onboarding process” and “cut the onboarding period from 12 weeks to 6” describe identical work, and only the second gives a reader something to act on.

Reference something concrete the organization has done, such as a product launch, a public commitment, or a recent report.

Most applicants skip this paragraph entirely, which is what makes it the cheapest way to separate yourself from the stack.

Generic admiration for a company culture you have never experienced does the opposite.

Thank the reader, restate your interest in one clause, and request a conversation directly.

Vague closings that trail off without asking leave the next move undefined, and a reader with forty applications to process will not define it for you.

Step three is where most letters collapse.

Coaches at Careerminds see the same failure across thousands of participants: people describe the job they held rather than the result they produced.

“Managed the onboarding process” and “cut the onboarding period from 12 weeks to 6” describe identical work.

Only the second one gives a reader something to act on.

A cover letter includes five components: a header with your contact details, a named greeting, an opening that states the role and your strongest qualification, a body paragraph proving that qualification with evidence, and a closing that requests an interview.

Anything beyond these five competes for space with them.

Component	What it does	Common failure
Header	Matches your resume and supplies contact details	Formatting differs from the resume
Greeting	Signals you researched the role	“To Whom It May Concern”
Opening	States the role and your strongest claim	Generic enthusiasm with no claim
Body	Proves the claim with a measurable result	Lists duties instead of outcomes
Company fit	Shows specific knowledge of the employer	“I admire your culture”
Closing	Requests the interview	Trails off without asking

Reading down the failure column gives you the fastest edit on a finished draft.

The company fit paragraph carries more weight than its length suggests and it is the only part of the letter a competing applicant cannot produce from a template.

The correct cover letter format is one page, 200 to 400 words, three to four short paragraphs, in a 10 to 12 point font that matches your resume, with one inch margins, saved as a PDF.

The word count comes from the Department of Labor, which recommends roughly that range across three to four short paragraphs (CareerOneStop, Cover Letters, 2025).

Harvard career services sets the same ceiling, advising applicants to stay factual and hold the letter to a single page (Harvard Mignone Center for Career Success, Guide to Creating a Strong Resume, 2026).

Element	Specification
Length	One page maximum
Paragraphs	3 to 4
Font	10 to 12 point, matching your resume
Margins	1 inch on all sides
File type	PDF, unless the application requests Word
File name	Your name, the role, and the document type

These rules serve one goal, which is making the letter readable in under two minutes.

Avoid tables, text boxes, columns, and graphics.

Applicant tracking systems frequently cannot parse them, and the same constraints that govern an ATS compliant resume apply to the letter.

Some do and some do not, and the honest answer is that it depends on the employer and on how many applicants reached the shortlist.

Treating the letter as a tiebreaker rather than a filter is the realistic view but the pressure is real on both sides.

There were 7.5 million job openings in the us in September 2026 (US Bureau of Labor Statistics, Job Openings and Labor Turnover Survey, 2026), and every one of them draws a stack of applications that gets read fast.

That same pressure is why most resumes never get read in full either.

Where the letter earns its place is narrower and more useful to know:

• When the posting explicitly asks for one, omitting it removes you from consideration regardless of anything else.
• When several applicants have equivalent experience, the letter decides who gets the first call.
• When your application needs context a resume cannot carry, such as a career change or an employment gap.
• When you are applying to a smaller organization, where the hiring manager reads every application personally.

If the field is optional, include one anyway.

Writing it costs twenty minutes but skipping it costs you something invisible, because nobody tells a rejected applicant which document made the difference.

Sarah Thompson, Head of People
Meridian Group
123 Commerce Drive, Chicago, IL 60601

Dear Sarah Thompson,

I have spent seven years leading workforce transition programs for organizations going through restructuring, which is the experience the People Operations Manager role at Meridian Group calls for.

At my current company, the manufacturing division reduced its workforce by 22% over 18 months. I managed the full transition program, coordinating with legal, running individual sessions with affected employees, and partnering with coaches to support re-employment. 94% of affected employees moved into new roles within four months, against an internal target of 60%.

I have followed Meridian’s work on workforce planning since your 2024 talent report, particularly the commitment to internal mobility before external hiring. That approach matches how I have structured every transition program I have run.

I would welcome the chance to discuss how my experience can support your team. I am available for a call at your convenience.

Sincerely,
Jane Doe

The letter runs 198 words and does two things a template cannot: it names a number, and it names something specific from the employer’s public record.

Address the layoff in one sentence, then spend the rest of the letter on evidence, because the gap matters far less to a reader than what you can demonstrate.

The harder problem is not the layoff.

It is that long tenure at one employer leaves you describing your work in language only that employer understands.

Amanda Augustine, Careerminds’ resident career expert (CPCC), puts the risk directly:

“Employers still assume long-tenured workers will land on their feet fastest because of their experience. The opposite is true. These are the employees who haven’t job-searched in a decade, whose networks have gone dormant, whose resumes don’t exist.“

The practical fix is translation as internal project names, proprietary system names, and job titles that exist nowhere else mean nothing to an outside reader.

Replace each one with what it did and what it produced.

A few specifics that work:

• State the layoff in one clause and move on, for example “following a restructure that eliminated my division.”
• Convert every internal term into a plain description of the function it served.
• Lead with the most recent quantified result, not the longest tenure.
• Name the skill the job posting asks for, then give the evidence immediately after.

Structured support shortens the gap considerably.

Careerminds participants land new roles in an average of 11.5 weeks, with a 95% placement rate, and much of that comes from rebuilding how people describe their own work before they send a single application.

Frequently, yes, and the more useful question is what happens to your application when generic AI output reaches a reader who has seen fifty versions of the same letter that week.

The evidence here is early but pointed.

One preprint study of a freelance hiring platform found that after the platform introduced an AI cover letter tool, the relationship between how well a letter matched the job and whether the applicant got a callback fell by 51% (Cui, Dias and Ye, Signaling in the Age of AI: Evidence from Cover Letters, 2025).

The same study found that time spent editing the AI draft correlated positively with hiring success.

A companion preprint modeled what happens when written applications stop carrying any signal, and found that applicants in the top ability quintile were hired 19% less often (Galdin and Silbert, Making Talk Cheap: Generative AI and Labor Market Signaling, 2025).

Both papers are working papers rather than peer-reviewed research, and both draw on freelance marketplace data rather than corporate hiring, so treat the figures as directional.

The practical conclusion holds regardless, so use AI to produce a draft, then rewrite it with details only you know.

Specific numbers and real reasons for wanting the job are what a model cannot invent.

Shift the focus from what you have done to what you can do, and prove it with evidence from education, volunteering, or personal projects rather than paid work.

A reader with no work history to assess will look for signals of capability anywhere they can find them.

What works when you have little paid experience:

• Lead with transferable skills, then back each one with a concrete example and an outcome.
• Use academic or extracurricular results, such as a final-year project with measurable findings or an organization you ran.
• Mirror the language of the job posting, so the reader can map your evidence to their requirements without effort.
• Name what you are actively building, such as a specific course or certification in progress.
• Keep it short, because padding is more obvious when there is less to say.

Do not open with an apology for your lack of experience.

The reader already knows your background from the resume, and spending the strongest line in the letter on your weakest point wastes the only part they are guaranteed to read.

Lead with what you bring instead.

The most common cover letter mistake is sending one generic letter to every employer, which a reader identifies within two sentences.

The rest cluster around the same root problem, which is writing about yourself rather than about the fit.

Mistake	What the reader sees	Fix
Repeating the resume	A second copy of a document already on file	Explain one entry rather than listing all of them
Duties instead of outcomes	“Responsible for managing the onboarding process”	Name what changed and by how much
Writing about what you want	“This role would help me grow”	State what the employer gets
Generic salutation	“To Whom It May Concern”	Find the name, or address the specific team
Running past one page	A letter that competes with the resume for attention	Cut to three or four paragraphs
Unproofed copy	Errors inside a document that is itself a writing sample	Read it aloud before sending
Wrong company or role name	Evidence the letter was reused	Check both against the posting every time

Reading the middle column is the fastest edit in this article.

If your letter produces any of those seven impressions, fix that before anything else.

Wrong company or role names end applications outright, and they happen almost exclusively when applicants reuse a template without checking.

Before sending anything, read the letter once with a single question: could every sentence in this have been written only for this job?

Delete the ones that could not, and a stronger professionally written resume alongside it will carry more weight than either document does alone.

• A cover letter explains your resume rather than repeating it, and the clearest proof of that is one achievement with a measurable result.
• Format is a solved problem: one page, a few short paragraphs, matching your resume, saved as a PDF with no tables or graphics.
• Hiring managers do not all read cover letters, but the letter decides shortlists when applicants are otherwise equivalent.
• After a layoff or long tenure, the real work is translating internal language into terms an outside reader understands.
• AI drafts are a starting point only, and the specific details you add afterward are what make the letter worth reading.

Short answers to the questions job seekers ask most about cover letters.

A cover letter is a one page document sent alongside your resume when applying for a job.

It explains why your specific background fits the role and the organization, adding context that a resume cannot carry on its own.

Three to four short paragraphs on a single page because a hiring manager should be able to read it in under two minutes.

No, but include one whenever the field exists.

Some postings state that no cover letter is required, and in those cases you can follow the instruction.

When the field is optional, a tailored letter separates you from applicants who left it blank.

Yes, use the same font, size, and header layout across both documents, because a mismatched pair looks assembled rather than prepared.
