Cover Letter Format: Structure, Spacing, and Layout

A cover letter can say all the right things and still get skimmed for four seconds and set aside, because the reader could not find the important parts. Format is what makes a letter scannable: where the greeting sits, how much white space surrounds each paragraph, whether the first line of body text lands above or below the fold of a preview pane. This guide covers the layout only. What to actually say in each paragraph is a separate problem, and worth solving separately.

Everything below follows standard business letter conventions, which is what university career offices and the U.S. Department of Labor still teach, and which every applicant tracking system and hiring manager expects to see.

What "cover letter format" actually means

Format covers three separate decisions that people tend to collapse into one:

Structure is which blocks appear and in what order. A cover letter is a business letter, so it inherits a fixed sequence: sender, date, recipient, greeting, body, close, signature. That order is not a style choice. Reordering it makes the document look unfamiliar in a way readers notice without being able to say why.

Layout is alignment, indentation, and spacing. This is where the block, modified block, and semi-block variants differ, and where most self-inflicted damage happens.

Page setup is margins, font, font size, and file type. These are the settings that determine whether your letter looks composed or cramped before a single word is read.

Get all three right and your letter becomes invisible in the good way: the reader processes your argument instead of your typography.

The seven blocks of a correctly formatted cover letter

Every properly formatted cover letter contains the same seven blocks in the same order, separated by a single blank line each.

1. Your contact header

Your name on its own line, slightly larger and bolder than the body text, followed by your contact details. The modern version omits your street address:

Jordan Reyes
Austin, TX | (512) 555-0143 | jordan.reyes@email.com | linkedin.com/in/jordanreyes

Two rules matter more than the exact arrangement. First, use the same name styling and the same contact line as the top of your resume, so the documents read as a matched pair when they land side by side in a folder. Second, include only channels you actually check. A portfolio URL that 404s is worse than no portfolio URL.

Full street addresses are a holdover from an era of mailed applications. Keep city and state, since employers do screen for location and time zone, and drop the rest.

2. The date

One blank line below your header, flush left, written out in full:

July 23, 2026

Write the month as a word rather than using numerals, since 07/08/2026 means two different days depending on which side of the Atlantic the reader sits on. If you drafted the letter last week, change the date before you send it. A stale date signals a mass-mailed template.

3. The recipient block

The hiring manager's name and title, then the company name, then the address:

Priya Nandakumar
Director of Product
Northwind Analytics
400 Congress Avenue
Austin, TX 78701

This block is genuinely optional in 2026 for online applications, and many strong letters skip it. Keep it when you are applying to a government agency, a law firm, a university, or any organization with formal correspondence culture, and when you are printing the letter. Drop it when you are pasting into an application form with a plain text field.

If you have the person's name but not their address, include the name and title and omit the street lines rather than dropping the block entirely.

4. The greeting

One line, flush left, followed by a colon in formal correspondence or a comma in less formal contexts:

Dear Ms. Nandakumar:

Use the full name without a title when you are unsure of someone's honorific: "Dear Priya Nandakumar:" is safe and reads as professional. When you cannot find a name at all, "Dear Hiring Manager:" is the accepted fallback. Avoid "To Whom It May Concern," which reads as dated, and avoid "Dear Sir or Madam," which reads as both dated and presumptuous about who is reading.

5. The body

Three or four paragraphs, single spaced internally, with a blank line between each and no indentation. The conventional sequence, which matches CareerOneStop's guidance from the U.S. Department of Labor, is:

1. Opening paragraph. The role you are applying for, where you saw it, and the single most relevant reason you are writing.
2. Evidence paragraph or two. Specific accomplishments that map to the requirements in the posting, using different examples or framing than your resume rather than restating it.
3. Fit paragraph. Something concrete about this employer and why it connects to you.
4. Closing paragraph. A forward-looking line about next steps.

The evidence section can be one paragraph or two, which is where the three-versus-four paragraph question resolves itself. Four is the practical ceiling. Five paragraphs on one page means each is too short to say anything.

6. The closing

One blank line below the last paragraph:

Sincerely,

"Sincerely" is the default and is never wrong. "Best regards," "Kind regards," and "Respectfully" are all acceptable. Skip "Cheers," "Thanks," and "Warmly," which are calibrated for email between people who already know each other. Capitalize only the first word and follow it with a comma.

7. Your typed name

Purdue OWL's formatting guidance suggests leaving at least three blank lines between the closing and your typed name, which is the space reserved for an ink signature on a printed letter. For a digital submission, one blank line is enough and looks less like an accidental gap.

If you are attaching a resume to a printed or emailed letter and want to flag it formally, an enclosure line goes one blank line below your name:

Enclosure: Resume

This is optional and mostly seen in academic and public-sector applications.

July 23, 2026

Priya Nandakumar
Director of Product
Northwind Analytics
Austin, TX 78701

Dear Ms. Nandakumar:

I am applying for the Senior Product Manager role (req. #4821) that
Northwind posted last week. I spent the past three years running the
billing and subscriptions surface at Ardent Software, which is the same
problem space your recent pricing overhaul is working through.

At Ardent I owned the migration of 140,000 accounts from a legacy billing
provider to an in-house system, coordinating across four engineering teams
over eleven months. We finished two weeks ahead of schedule with a 0.3%
support ticket increase, against a forecast of 4%. In the year after, I
led the usage-based pricing rollout that lifted net revenue retention from
104% to 118%.

What drew me to Northwind specifically is the decision to publish your
pricing changelog publicly. I have argued for that internally twice and
lost both times, and I would like to work somewhere that already believes
transparency is a feature rather than a risk.

I would welcome the chance to talk through how that experience maps to
what your team is building. My resume is attached, and I am available for
a call any afternoon this week or next.

Sincerely,

Jordan Reyes

Notice what the layout is doing: every block is flush left, no paragraph is indented, and the blank lines do all the visual separation work. The reader can find the job title, the numbers, and the ask without reading a single full sentence.

Page setup: margins, font, size, and spacing

These are the settings that decide how the letter looks before anyone reads it. Harvard's career office and Yale's Office of Career Strategy converge on essentially the same specification, and it has not moved much in twenty years.

Three of these deserve elaboration.

Do not justify the text. Full justification stretches spaces between words to force a flat right edge, which produces uneven rivers of white space in a document with short paragraphs. Left aligned with a ragged right edge is what business correspondence uses and what reads most naturally.

Do not both indent and add a blank line. Indentation and blank lines are two competing ways to signal a paragraph break. Business letters use blank lines. Using both makes the page look accidentally formatted.

Match your resume exactly. Same font, same size, same header treatment, same accent color if you use one. A hiring manager opening two documents with different typography sees two documents. Opening two with matched typography, they see one candidate who is careful. If you built your resume from a template, reuse its font stack in the letter.

Block, modified block, or semi-block: which layout should you use?

Business letters have three traditional layouts. In practice, one of them is the answer almost every time.

Use block format. It is the layout Purdue OWL's cover letter workshop treats as standard, it is what applicant tracking systems handle most cleanly, and it is what every reader under fifty expects. Modified block is defensible for a printed letter on letterhead in law, finance, or academia. Semi-block has no real use case in job applications anymore.

How long should each part be?

One page is the ceiling, but the useful target is much shorter. Here is a realistic allocation for a 350-word letter:

A letter that fills a full page of 11 point text is roughly 600 words, which is nearly double what most applications need. When a letter runs that long, it is almost always because it has become a prose retelling of the resume. If that is what is happening, fix the resume instead and let it carry the history. The letter's job is the argument the resume cannot make.

How to format a cover letter in the body of an email

Emailing a letter is a different document, not the same document pasted into a different container. The email header already carries your name, your address, the date, and the recipient, so repeating them in the body is redundant.

What changes:

• Delete the contact header, the date, and the recipient's mailing address. Start at the greeting.
• Write a real subject line. "Senior Product Manager (Req #4821) - Jordan Reyes" is findable six weeks later. "Job application" is not.
• Shorten everything. Aim for 150 to 200 words. Email is read on phones and the fold sits high.
• Break paragraphs harder. Two to three sentences per paragraph maximum, with a blank line between each. Dense blocks in an email client are functionally unreadable on a small screen.
• Move contact details into the signature. Name, title or target role, phone, email, LinkedIn.
• Send plain text or minimal HTML. No background colors, no custom fonts, no images in the signature.

If the posting asks you to attach a cover letter rather than write one in the email, do both: attach the full formatted PDF and write three sentences in the email body pointing at it. An email with an attachment and no message reads as careless.

File format, file name, and ATS considerations

Send a PDF unless the posting explicitly asks for a Word document. A PDF renders identically on every machine, which is the entire point of spending time on spacing and font choice. Modern applicant tracking systems parse PDFs without difficulty, and both Harvard and Yale career resources now recommend PDF for electronic submission.

Name the file so it survives being downloaded. Jordan-Reyes-Cover-Letter-Product-Manager.pdf is identifiable in a folder of two hundred files. cover letter final v3 (2).pdf is not, and it tells the reader something about you before they open it.

Keep the structure text-based. The formatting choices that break parsing are the same ones that break resume parsing: text inside images, text boxes, multi-column layouts, headers and footers containing critical information, and tables used for layout. A cover letter has no reason to use any of them. If you want to understand what parsers do and do not handle, the guide to applicant tracking systems covers the mechanics, and you can run your resume through the ATS resume checker to see what a parser actually extracts.

Do not password protect or track-changes the file. Both happen more often than you would expect, and both mean your application does not get read.

Formatting mistakes that make a good letter look careless

These are the errors that show up most often, roughly in order of how badly they land:

1. Double spaced body text. Turns a 350-word letter into two pages and signals that the writer has never sent business correspondence.
2. The wrong company name. The reason to reformat rather than reuse: template letters carry the last employer's name in the third paragraph. Search your draft for every proper noun before sending.
3. Mismatched fonts between the resume and letter. Reads as two documents assembled from different sources, because it is.
4. A wall of text. One 300-word paragraph is not a cover letter, it is a paragraph. Break at the argument boundaries.
5. Centered body text. Centering is for wedding invitations. Everything but a name header should be left aligned.
6. A pixelated signature image. Low-resolution scanned signatures look worse than no signature. For digital submissions, the typed name is complete.
7. Justified text with short paragraphs. Produces visible gaps between words and an oddly gappy page.
8. Margins under half an inch. Cramped pages read as desperate and print badly.
9. A date left over from a previous application. Instant evidence of a mass send.
10. "To Whom It May Concern." Not a formatting error strictly, but it sits in the format's most visible line and dates the whole document.

A quick formatting checklist before you send

Run through this in under two minutes:

• One page, three or four paragraphs, under 400 words
• Margins equal on all four sides, one inch preferred
• Same font and size as your resume, 10 to 12 point
• Single spaced body, blank line between paragraphs, no indentation
• Everything left aligned, nothing justified, nothing centered except possibly your name header
• Date is today's date, written with the month spelled out
• Greeting uses a real name where you could find one
• Correct company name and job title in every place they appear
• Saved as a PDF with a descriptive file name
• Opened once in a PDF reader to confirm nothing shifted

Get the structure right, then spend your time on the argument

Formatting a cover letter well takes about ten minutes the first time and about zero minutes every time after, because the layout never changes. That is the point: the format is a solved problem, and every minute you are not spending on margins is a minute you can spend on the two or three specific sentences that make a hiring manager want to talk to you.

Once the structure is settled, the remaining work is making the content specific to one job at one company. resumelon builds the resume and the matching letter from the same source material, so the fonts, headers, and spacing line up automatically and you only have to think about what to say. Start with the cover letter generator for a first draft built from a real job description, browse the cover letter templates if you would rather start from a finished layout, or build the resume first with the resume generator and let the letter inherit its styling.
