Cover Letter Format Guide (2026)

The standard cover letter format follows traditional business letter conventions that hiring managers expect. Your cover letter should contain five key sections in order: header with contact information, date and employer details, salutation, body paragraphs, and closing with signature. The header includes your full name, phone number, email address, and optionally your LinkedIn URL or city and state. Place this at the top, matching the style of your resume header for a cohesive look. Below the header, add the date followed by the recipient's name, title, company name, and address. The salutation should be 'Dear [Name]' followed by a colon in formal contexts or a comma for a slightly warmer tone. The body consists of three to four paragraphs an opening hook, one or two achievement paragraphs, and a closing with a call to action. End with 'Sincerely' or 'Best regards' and your name.

Proper spacing ensures your cover letter is easy to read and looks polished on screen and in print. Use single line spacing within paragraphs. Add one blank line between each paragraph, between the date and the employer's address, between the address and the salutation, and between the closing and your name. Set all four margins to 1 inch for a balanced appearance. If your content is running short, you can increase margins to 1.25 inches or reduce them to 0.75 inches to fit the page. The entire letter should fit on one page. If you find yourself pushing onto a second page, tighten your language rather than shrinking the font or margins below standard sizes. Left-align all text do not center or justify your paragraphs. Block format (everything left-aligned with no indentation) is the most widely accepted style for professional correspondence.

Your font choice signals professionalism before the hiring manager reads a single word. Stick to clean, widely available fonts that render consistently across devices and operating systems. The best choices for 2026 are Calibri (the default in most modern word processors), Arial, Garamond, Cambria, and Georgia. Avoid decorative, script, or display fonts they reduce readability and can look unprofessional. Set your body text between 10.5 and 12 points. Your name in the header can be slightly larger, around 14 to 16 points, to create a visual hierarchy. Never go below 10 points, as smaller text strains the reader's eyes and suggests you are trying to cram too much content onto the page. Use the same font in your cover letter and resume for consistency. If your resume uses Calibri at 11 points, your cover letter should match. This creates a unified application package that looks intentional and polished.

The ideal cover letter is 250 to 400 words long enough to make a compelling case but short enough to respect the reader's time. Research consistently shows that hiring managers prefer concise cover letters. A Jobvite survey found that 26% of recruiters consider a cover letter important, but virtually none want to read more than one page. Three to four paragraphs is the sweet spot. Your opening paragraph should be two to three sentences. Each body paragraph should be three to five sentences focused on a single theme or achievement. Your closing should be two to three sentences. Count your words and cut anything that does not directly support your candidacy. If a sentence merely repeats what is on your resume without adding context, remove it. The cover letter's job is not to restate your resume but to expand on your most relevant qualifications with stories and context.

Your cover letter header is the first visual element the reader encounters. Include your full name prominently at the top, followed by your contact details on one or two lines. A simple format works: phone number, email, LinkedIn URL, and city/state separated by vertical bars or bullet characters. Match the header design to your resume if your resume has a horizontal line below the header, use the same line in your cover letter. This consistency shows attention to detail. When saving your cover letter, always export as PDF unless the job posting specifically requests a Word document. PDF preserves your formatting across all devices and operating systems. Name the file clearly: FirstName-LastName-Cover-Letter.pdf. Avoid generic names like 'cover letter.pdf' or 'document1.pdf.' If the application system has a character limit for file names, abbreviate to something recognizable like 'JSmith-CL-CompanyName.pdf.'
