A cover letter is your chance to speak directly to the hiring manager and make a case for why you are the right person for the job.
This guide walks you through everything you need to know about how to write a cover letter for a resume, from structure and format to what to include and what to avoid.
How to write an effective cover letter
An effective cover letter is tailored, specific, and easy to read.
It opens strongly, builds a clear case for your candidacy in the middle, and closes with a confident call to action.
Every sentence should earn its place, so follow these steps to write a cover letter that works.
Step 1: Research before you write
Before you type a single word, do your homework.
Read the job description carefully and note the skills, responsibilities, and qualities the employer is looking for.
Then spend a few minutes on the company's website, recent news, and LinkedIn page.
The more you understand about what they need and who they are, the more targeted your letter can be.
This preparation shapes everything from your opening line to the examples you choose to include.
Step 2: Write a strong opening paragraph
Your first paragraph needs to earn the hiring manager's attention.
Avoid starting your cover letter with "I am writing to apply for", it is flat and tells them nothing useful.
Instead, lead with something that immediately communicates your value.
Three approaches that work well:
- Lead with a career achievement: Open with a result directly relevant to the role. For example: "Over the past five years, I have consistently exceeded quarterly sales targets by an average of 22%, which is exactly the kind of performance I am looking to bring to your team."
- Show genuine interest in the company: Reference something specific about their work, a recent project, a company value, or a product you genuinely admire. Vague flattery is easy to spot. Specific, researched enthusiasm is not.
- Make a personal connection: If a current employee referred you, or if you met someone from the company at an event, mention it early. It creates an immediate point of recognition, and our article on using a referral in your cover letter covers how to handle that well.
Step 3: Build your case in the body
The middle of your cover letter is where you make your argument.
Use one or two paragraphs to show that your background aligns with what the role requires.
Do not simply list skills, connect them to outcomes.
Think about what the hiring manager actually needs to solve or achieve, and show how your experience positions you to help with that.
A useful test is if you removed the company name and the letter could apply to any employer in your industry, then it is not specific enough.
What you might include in the body:
- A key professional achievement with measurable impact
- Context around a skill that is central to the role
- Evidence of sector knowledge or industry understanding
- A brief example of how you have handled a challenge similar to what this role demands
Step 4: Close with purpose
Your closing paragraph should do three things: reaffirm your enthusiasm for the role, briefly summarize the value you bring, and invite the hiring manager to take the next step.
Keep it direct and confident.
Avoid phrases like "I hope to hear from you", they are passive.
Instead, try something like: "I would welcome the opportunity to discuss how my experience in client retention could support your team's goals. Please feel free to reach out at the number below."
Step 5: Tailor, proofread, and submit
Before you send your cover letter, work through this checklist:
- Re-read the job description and confirm your letter addresses the key requirements
- Check every name, including the hiring manager, the company, and the job title, for accuracy
- Proofread for spelling, grammar, and punctuation errors, reading aloud helps catch problems a visual scan misses
- Confirm the file name matches your resume, using a format such as: firstname_lastname_coverletter
A single error can undermine an otherwise strong application, so take the time to check before you submit.
What does a cover letter look like for a job?
A cover letter for a job looks like a professional one-page document, structured like a formal business letter.
It includes a header with your contact information and the employer's details, a greeting addressed to a named person wherever possible, three to four focused paragraphs, and a professional sign-off.
Here is what each section contains:
- Header: Your full name, location, phone number, email address, and LinkedIn profile if relevant. Below that, the company name, the hiring manager's name, the company address, and the date.
- Greeting: Dear [Hiring Manager's Name], or Dear [Department] Team if you cannot find a specific name.
- Opening paragraph: A strong hook that introduces who you are, what you are applying for, and why you are interested. Lead with your most compelling credential or a specific reason you are drawn to this company.
- Body paragraph(s): One or two paragraphs covering your most relevant experience, key achievements, and how your skills align with what the role requires. Use specific examples and back up your claims with results wherever possible.
- Closing paragraph: A confident close that reaffirms your interest, summarizes the value you bring, and includes a clear call to action inviting the hiring manager to get in touch.
- Sign-off: Kind regards, Best regards, or Sincerely, followed by a comma and your full name.
This structure is consistent across industries and experience levels.
What changes is the content inside each section, which should always be tailored to the role you are applying for.
What to put in a cover letter?
The letter should include key details like your contact information, a professional greeting, a compelling opening, evidence of your relevant skills and achievements, a clear reason why you want this specific role, and a confident closing with a call to action.
Here is a breakdown of the key elements:
- Contact information: Your name, phone number, email, and location at the top of the page, matched to how they appear on your resume.
- Greeting: Address the hiring manager by name. If you cannot find it, "Dear Hiring Manager" is acceptable. Avoid "To Whom It May Concern."
- Opening hook: Lead with something that grabs attention, whether that is a strong accomplishment, a relevant result from your career, or a genuine and researched connection to the company.
- Relevant experience and skills: Highlight the experience most applicable to the job. Do not repeat your resume line by line. Add context, explain impact, and connect your background to what the employer needs.
- Achievements with evidence: Include specific results where possible. Numbers and outcomes are more persuasive than general claims.
- Company alignment: Show that you have done your research. Explain why this company and this role appeal to you specifically.
- Closing and call to action: Express your enthusiasm and invite the hiring manager to contact you. Keep it confident without being presumptuous.
- Professional sign-off: Use a formal closing such as "Kind regards" or "Sincerely," followed by your full name.
Why is a cover letter important?
A cover letter matters because it gives you the opportunity to make a direct, personal impression before the hiring manager decides whether to call you in.
Your resume lists what you have done, but your cover letter explains why it is relevant and what you bring to this specific role and company.
It also functions as a writing sample, whether you intend it to or not, so clarity, tone, and attention to detail all signal the kind of professional you are before you set foot in an interview.
For most professional applications, a well-written, tailored cover letter is one of the most effective ways to separate yourself from candidates who apply without one.
Do I need a cover letter for my resume?
In most cases, yes.
Even when a posting lists a cover letter as optional, submitting one demonstrates initiative and gives you an additional opportunity to make your case.
The exception is when an application system has no field for one, or when an employer has specifically asked you not to include it.
Formatting a cover letter
Your cover letter should be formatted as a clean, single-page document with consistent fonts, standard margins, and clear paragraph spacing.
The goal is a letter that is easy to read and looks professional whether viewed on screen or printed.
The key principles to follow:
- Length: One page, three to four paragraphs, around 250 to 400 words for most roles.
- Margins: Standard one-inch margins on all sides.
- Alignment: Left-aligned body text, with your header centered if your template calls for it.
- Spacing: Single spacing within paragraphs, with a clear line break between each section.
- File format: Save and submit as a PDF unless the employer specifies otherwise. This preserves your formatting across devices.
Formatting signals professionalism.
A cluttered or inconsistently styled letter suggests a lack of attention to detail, and a dedicated formatting guide with full specifications is coming soon.
What font should a cover letter be?
Use a clean, professional font at between 10 and 12 points.
The most reliable choices are Arial, Calibri, Garamond, and Georgia; all easy to read on screen and in print, and safe for applicant tracking systems.
Avoid decorative or novelty fonts.
Your letter is a professional document and the font should support readability, not compete with your content.
Use the same font throughout, including the header, and match it to your resume font where possible.
A consistent visual presentation across your application looks considered and deliberate.
What sort of spacing should a cover letter use?
Use single line spacing within paragraphs, with one blank line between each paragraph or section.
This creates a clean, open layout that is easy for the hiring manager to read quickly.
Between your header, greeting, body, and sign-off, use clear visual breaks rather than compressing sections together to fit more content on the page.
If your letter feels cramped, that is usually a sign it needs editing rather than tighter spacing.
Standard one-inch margins on all sides work well across most templates and submission formats.
How long should a cover letter be?
Only one page long, containing three to four paragraphs and between 250 and 400 words.
Hiring managers read a high volume of applications, and a concise, well-structured letter is more effective than a longer one.
Focus on your two or three strongest points rather than trying to cover everything, if a detail is already on your resume and adds no new context, it does not need to be in the cover letter.
For very senior positions or academic applications a slightly longer letter may be appropriate, but one page remains the standard expectation for the vast majority of roles.
What makes a good cover letter?
A good cover letter is tailored, concise, and specific.
It opens with a compelling hook, makes a clear case for the candidate's fit with the role, and closes with a confident call to action.
Every section adds something the resume does not.
The qualities that separate a strong cover letter from a forgettable one:
- Specificity: Generic cover letters are easy to spot and easy to ignore. Reference the company, the role, and the specific value you bring to that context.
- Evidence over claims: Saying you are a strong communicator means little without an example. A good cover letter shows the hiring manager what you have achieved, not just what you believe about yourself.
- Conciseness: Every sentence should move the reader forward. If it does not add information or strengthen your case, cut it.
- Tone: It must sound like a confident, grounded professional, not a sales pitch. Aim for the tone you would use speaking with a senior colleague you respect.
- Consistency with your resume: Your cover letter and resume should feel like they come from the same person. Inconsistencies in dates, job titles, or tone can create doubt.
A common mistake is treating the cover letter as a summary of the resume.
It is not.
It is an argument, and a good argument needs a clear position, supporting evidence, and a purposeful close.
How do I customize my cover letter for different industries?
Customize your cover letter for different industries by adjusting the tone, language, and examples to reflect what that sector values.
The structure stays the same, but the content, emphasis, and style should shift to match the expectations of each field.
1. Research the industry's expectations
Before you write, spend time understanding what the industry values most.
A law firm looks for precision and professionalism.
A tech startup may respond better to a direct, results-driven approach.
A nonprofit will want to see genuine alignment with their mission.
Adjust your language and emphasis accordingly.
2. Match the tone to the culture
- Corporate and finance roles: Formal, precise, focused on measurable outcomes.
- Creative and marketing roles: Confident, with personality, showing an understanding of audience.
- Healthcare and education roles: Empathetic, focused on service and impact.
- Tech and startup roles: Direct, achievement-oriented, comfortable with change.
- Nonprofit and public sector roles: Mission-driven, showing shared values.
3. Use the right language
Every industry has its own vocabulary.
Read several job descriptions in your target field and note the terms that appear repeatedly.
Using that language naturally in your letter signals to the hiring manager that you understand the work, not just the title.
4. Adjust what you lead with
A finance professional might open with a revenue figure but a teacher might open with a moment that shaped their approach to learning.
Lead with what that industry most values, and tailor each letter accordingly.
How to include salary requirements in a cover letter
Only include salary requirements in a cover letter when the employer explicitly asks for them.
If the job posting requests it, state a specific range based on your research rather than a single figure, and keep the language professional and open to discussion.
When salary requirements are requested, handle them this way:
- Do your research first: Use salary data from sources such as the Bureau of Labor Statistics, Glassdoor, or LinkedIn Salary to understand the going rate for the role in your location and industry. Your range should be grounded in real market data.
- Give a range, not a fixed number: Stating a range signals flexibility and leaves room for negotiation. For example: "Based on my research and experience, I am looking for a base salary in the range of $65,000 to $75,000, though I am open to discussing the full compensation package."
- Keep it brief: One or two sentences is sufficient. Do not let salary discussion dominate your cover letter.
- Position it in the closing paragraph: Salary expectations fit most naturally at the end of the letter, after you have already made your case.
If the posting does not ask for salary requirements, do not include them.
Raising compensation unprompted can shift the focus of your application before the hiring manager has had the chance to evaluate your fit.
What are common mistakes to avoid when writing a cover letter?
The most common cover letter mistakes are using a generic template for every application, leading with a weak opening, repeating the resume rather than adding to it, and submitting without proofreading.
Any one of these can undermine an otherwise strong application.
Here are seven mistakes to watch for:
1. Using a generic cover letter
Sending the same letter to every employer with only the company name changed is one of the most damaging habits in a job search.
Hiring managers can tell immediately, so tailor every letter to the specific role and company, even if the changes are focused and efficient.
2. A weak or clichéd opening
"I am writing to express my interest in..." tells the reader nothing interesting.
Open with something specific and compelling.
Your first sentence should give the hiring manager a reason to keep reading.
3. Summarizing your resume instead of adding to it
Simply restating your job history adds no value.
Use the space to provide context, explain impact, and show how your background connects to what this employer needs.
4. Focusing on what you want rather than what you offer
A cover letter is not about what the job can do for your career.
It is about what you can do for the employer.
Therefore, keep the focus on your contributions.
5. Spelling and grammar errors
A single typo can create a disproportionately negative impression, particularly for roles where written communication matters.
Proofread carefully and read your letter aloud before submitting.
6. Over-relying on AI-generated content
AI tools can be a useful starting point, but submitting a letter that has not been personalized and rewritten in your own voice is a risk.
Use AI to help structure your draft, then make the content genuinely yours.
7. Making it too long
One page is the standard.
If your letter runs longer, it almost always contains sentences that can be cut without losing anything important.

The table below covers the most commonly searched roles, and each template follows the structure outlined in this guide.
Key takeaways
- A great cover letter is one page long, tailored to the specific role and company, and opens with a compelling hook that gives the hiring manager a reason to keep reading.
- Every section should add something your resume does not, whether that is context around an achievement, evidence of company research, or a clear explanation of why you are the right fit.
- Keep your language direct and professional, avoid repeating your resume, and always proofread carefully before you submit.

Frequently asked questions about cover letters
Whether you are writing your first cover letter or refining your approach, these answers cover the most common questions job seekers ask.
Can a cover letter be two pages?
Yes, but a cover letter should be one page long ordinarily, containing between 250 and 400 words.
Two pages is too long for this format and risks losing the hiring manager's attention before they reach your strongest points.
If your letter runs over, identify sentences that repeat points already made and remove them.

Do I need to address my cover letter to a specific person?
Addressing your letter to a named individual shows that you have taken the time to find out who will be reading it, and that effort is noticed by hiring managers.
Check the job posting first, then search on LinkedIn or the company website if a name is not listed.
If you genuinely cannot find one, "Dear Hiring Manager" is a professional and widely accepted alternative.
Should my cover letter match my resume design?
A consistent visual presentation across your cover letter and resume signals attention to detail and creates a more cohesive application.
Using the same font, spacing, and color palette shows your application has been put together with care.
