Cover letter format: layout, font and spacing

The right format is the one nobody notices: a single, clean, left-aligned page that is easy to skim and impossible for software to misread. Here are the rules and the three accepted layouts.

Compare the three layouts

Full block: Everything aligned left, a blank line between paragraphs, no indents. The standard in the US and the safest choice for any printed or PDF letter.

The order of a cover letter

  1. Your header: name, phone, email, LinkedIn or portfolio link. Match your résumé header so the two look like a set.
  2. Date (printed or PDF letters only).
  3. Employer: hiring manager's name and title, company. Street address optional.
  4. Greeting: "Dear Ms. Patel," or "Dear Hiring Manager,". See how to address a cover letter.
  5. Opening paragraph: the role, the company and your hook.
  6. One or two body paragraphs: proof, with results.
  7. Closing paragraph: why them, thanks, next step.
  8. Sign-off and name: "Sincerely," or "Kind regards,". A scanned signature is optional.

Formatting that trips up applicant tracking systems

Most ATS software reads cover letters as plain text. Two-column designs, text boxes, tables, headers and footers, icons and images can come out scrambled or be dropped entirely. If you use a designed template, check it by copying all the text into a plain text editor: if it reads in the right order, you are fine. More in our ATS-friendly cover letter guide.

Frequently asked questions

What is the correct format for a cover letter?

One page, single-column, left-aligned (full block): your contact details, the date, the employer's details (optional online), a greeting, three or four short paragraphs with a blank line between them, and a sign-off with your name.

What font and size should a cover letter use?

A standard, readable font at 10.5–12pt, matching your résumé: for example Calibri, Arial, Helvetica, Georgia, Cambria or Garamond. Use one-inch (2.5 cm) margins and single line spacing.

Should I send my cover letter as a PDF or Word document?

PDF keeps your layout intact and is accepted almost everywhere. Send .docx only when the employer asks for it. Name the file clearly, for example Alex-Morgan-Cover-Letter.pdf.

Do I need to include the date and the employer's address?

For a printed or PDF letter, the date is standard and the employer's name and company are a nice touch; a full street address is optional. In an email or online form, skip both.
