A badly formatted cover letter can get rejected before a human ever reads it. Applicant tracking systems parse your document for structure and readability, and hiring managers form a first impression within seconds of opening the file. Even strong content loses its impact when the layout is sloppy, the font is hard to read, or the spacing feels off.
This guide covers the standard cover letter format used across US job applications, the technical rules you need to follow, and the specific formatting choices that keep your letter clean for both software and human readers. If you need a broader walkthrough of what to write inside each section, start with our full guide on how to write a cover letter.
The Standard Cover Letter Format
Every professional cover letter follows the same six-part structure. Deviating from this layout confuses readers and can cause parsing errors in applicant tracking systems. Here is the breakdown from top to bottom.
1. Header
Your header includes your full name, phone number, professional email address, and optionally your LinkedIn URL and city and state. A full street address is no longer expected for most applications, but including your general location helps recruiters who filter by geography. If you are using a matching resume template, keep the header design consistent across both documents.
2. Date
Write the full date directly below your header. Use a standard format like "January 15, 2025" rather than abbreviations. If you are reusing a draft from a previous application, update the date every time.
3. Employer's Address
Include the hiring manager's name (if known), their title, the company name, and the company address. If the job posting does not list a specific contact, "Hiring Manager" or "Hiring Committee" is acceptable in place of a name. This block sits below the date and above the salutation.
4. Salutation
Address the letter to a specific person whenever possible. "Dear Ms. Chen," or "Dear Mr. Rodriguez," is ideal. When you cannot find a name, "Dear Hiring Manager," is the standard fallback. Avoid outdated openings like "To Whom It May Concern" or "Dear Sir/Madam," which sound impersonal and dated.
5. Body
The body is three to four paragraphs that make your case. The first paragraph states which role you are applying for and why you are interested. The middle paragraphs provide evidence of your qualifications with specific achievements and metrics. The final paragraph closes with a call to action and a professional sign-off tone. We break this structure down in detail further below.
6. Sign-Off
Close with a professional phrase like "Sincerely," "Best regards," or "Thank you," followed by a blank line and your full name. If you are submitting a printed or PDF letter, you can include a handwritten or digital signature between the closing phrase and your typed name, but this is optional for most digital applications.
Formatting Rules
Getting the layout right is as important as getting the content right. These are the technical specifications that keep your cover letter looking professional and parsing correctly.
Font: Use a clean, professional typeface at 10.5 to 12 point size. Safe choices include Arial, Calibri, Garamond, Helvetica, and Times New Roman. Avoid decorative or script fonts, which are harder to read on screen and may not render correctly in every system.
Margins: Set one-inch margins on all four sides. This is the universal default for business correspondence. If your content slightly overflows one page, you can reduce margins to 0.75 inches, but going narrower than that makes the page look cramped.
Length: Keep your cover letter to one page, between 250 and 400 words. Hiring managers review dozens of applications and favor letters that get to the point quickly. If you are wondering whether a longer letter is ever justified, see our guide on can a cover letter be two pages.
Spacing: Use single line spacing within paragraphs and one blank line between paragraphs. Do not indent the first line of each paragraph. Left-align all text; do not use justified alignment, which creates uneven spacing between words and can cause readability issues.
File format: Save and submit your cover letter as a PDF unless the employer specifically requests a different format. PDFs preserve your formatting across devices and operating systems, and they cannot be accidentally edited by the recipient. A Word document (.docx) is the only common alternative you should consider, and only when the posting explicitly asks for it.
File naming: Name your file clearly so it is easy for the recruiter to locate. Use the format FirstName-LastName-Cover-Letter.pdf. Avoid generic names like "cover letter.pdf" or "document1.pdf," which blend in with hundreds of other submissions.
Cover Letter Body Structure
The body paragraphs are where your cover letter either earns an interview or loses the reader's attention. Each paragraph has a specific job to do.
Opening Paragraph
Your opening states the job title you are applying for, the company name, and one compelling reason you are a strong fit. The best openings lead with a relevant achievement or a specific connection to the company rather than a generic statement about being excited to apply. Keep this paragraph to three or four sentences. For detailed strategies on writing a strong opener, see our guide on how to start a cover letter.
Evidence Paragraphs
The middle one to two paragraphs are the core of your cover letter. This is where you present your strongest qualifications, backed by measurable results. Each paragraph should focus on a single theme: a key skill, a relevant project, or a professional accomplishment that directly maps to the requirements listed in the job posting.
Use numbers whenever possible. "Managed a $2.4M annual budget" is more convincing than "experienced in budget management." Reference specific tools, technologies, or methodologies mentioned in the job description to show that your skills align with what the team already uses.
If you are making a career transition, use these paragraphs to translate your previous experience into the language of the new field. The career change cover letter guide covers this in depth.
Closing Paragraph
The final paragraph thanks the reader, expresses continued interest, and includes a clear call to action such as requesting a conversation or stating your availability for an interview. Do not introduce new qualifications here. The closing should feel confident and forward-looking, not desperate or passive. For specific techniques and phrasing, read our guide on how to end a cover letter.
ATS-Friendly Formatting Tips
Most large employers and many mid-size companies use applicant tracking systems to screen applications before a human sees them. Formatting mistakes can cause your cover letter to be misread, garbled, or filtered out entirely. Follow these rules to stay ATS-safe.
Use standard section headings or no headings at all. ATS software expects a clean block of text. If you include headings, keep them simple. Avoid creative headers that the parser will not recognize.
Do not use text boxes, tables, or columns. Many ATS platforms cannot read content placed inside text boxes or multi-column layouts. Keep your cover letter in a single-column, top-to-bottom flow.
Avoid headers and footers for essential information. Some systems skip content placed in the header or footer area of a document. Put your contact information in the main body of the page instead.
Stick to standard fonts. Custom or embedded fonts may not display correctly when the ATS converts your file. The safe fonts listed in the formatting rules section above all parse reliably.
Do not embed images or logos. A personal logo or headshot might look polished, but ATS platforms cannot read image content and may reject files that contain them.
Include relevant keywords naturally. Mirror the language from the job posting in your letter. If the employer asks for "project management experience," use that exact phrase rather than a synonym like "initiative oversight." This helps your application match the ATS keyword filters without sounding forced.

Email vs. Uploaded Cover Letter Format
How you submit your cover letter affects how you should format it. The two most common methods are uploading a file through an application portal and pasting the letter into an email body.
Uploaded Cover Letter (Application Portal or Attachment)
When uploading a file or attaching it to an email, use the full formal format described above: header, date, employer address, salutation, body, and sign-off. Save the file as a PDF with a professional file name. This is the format most employers expect when they provide an upload field or ask for an attachment.
Email Cover Letter (Pasted in the Email Body)
When the employer asks you to email your application directly, paste your cover letter into the email body rather than only attaching it. In this case, simplify the format:
- Skip the header block and employer address. The email itself contains your contact information and the recipient's address.
- Use the email subject line to state the position: "Application for Marketing Manager -- [Your Name]."
- Start directly with the salutation and body. "Dear Ms. Torres," followed immediately by your opening paragraph.
- Keep the sign-off. End with "Sincerely," or "Best regards," your name, phone number, and email address below it.
- Attach your resume as a separate PDF file so the employer has both your cover letter in the email and your resume as a downloadable document.
Even when pasting into an email, keep the content to approximately 250 to 400 words. The same length guidelines apply regardless of the delivery method.
Properly formatted cover letter example
Notice the clear structure: header, date, employer address, salutation, three focused body paragraphs, and a professional sign-off.
Subject: Application for the Marketing Coordinator position

Email cover letter format example
This version is streamlined for pasting directly into an email body. The header block and employer address are omitted since the email itself provides that context.
Subject: Application for the Operations Analyst position -- James Okoro

Before You Submit
Use this quick checklist before sending any cover letter. A formatting error is one of the easiest reasons for a recruiter to pass on an otherwise strong candidate.
- Confirm your letter fits on one page with standard margins and font size.
- Verify that the company name, job title, and hiring manager's name are correct and spelled properly.
- Check that the file format is PDF unless the employer requested something different.
- Make sure the file name follows a clear convention like FirstName-LastName-Cover-Letter.pdf.
- Read the letter on screen and in print preview to catch any spacing or alignment issues that are not visible in the editing view.
- Remove any placeholder text such as brackets or template instructions that should have been replaced.
- Run spell check, then read the letter aloud to catch errors that spell check misses.

Frequently Asked Questions
What is the best font for a cover letter?
The best fonts for a cover letter are clean, professional, and widely available. Arial, Calibri, Garamond, and Times New Roman are all safe choices. Use a size between 10.5 and 12 points. The goal is readability, not style. If the recruiter has to squint or if the ATS cannot parse the font, nothing else in the letter matters.
How long should a cover letter be?
A cover letter should be one page, between 250 and 400 words. This gives you enough space to introduce yourself, present two or three key qualifications, and close with a call to action. Anything longer risks losing the reader's attention. Browse our cover letter examples to see how effective letters stay within this range.
Should a cover letter be one page or two?
One page is the standard for the vast majority of US job applications. The only exceptions are academic positions, federal government applications, and senior executive roles where the employer explicitly expects a longer document. For every other situation, keep it to one page.
What is the difference between a cover letter and a resume?
A resume lists your work history, skills, and education in a structured, scannable format. A cover letter adds context by explaining why you are interested in a specific role, how your experience connects to the employer's needs, and what makes you a strong fit beyond the bullet points. They serve different purposes and should not duplicate each other. For a deeper comparison, see our guide on cover letter vs. resume.
Do I need a cover letter if the application does not require one?
In most cases, yes. Submitting a cover letter when one is optional gives you an advantage over candidates who skip it. It is an opportunity to demonstrate interest, provide context, and differentiate yourself. The only time to skip it is when the application system literally does not provide a way to include one.
Where can I find cover letter templates with the right format?
Our cover letter templates are pre-formatted with the correct margins, spacing, font sizes, and structure. Choose a design that matches your industry, fill in your details, and customize the content for each application. You can also browse cover letter examples to see how other candidates have applied these formatting rules in real applications.
