Cover Letter Format Guide

Proper formatting is crucial for cover letters. A well-formatted cover letter looks professional, is easy to read, and passes ATS screening. This guide covers everything you need to know about cover letter formatting.

Quick answer: Format your cover letter with 1-inch margins, single or 1.15 line spacing, 10-12pt professional font (Arial, Calibri, or Times New Roman), and save as PDF. Include your contact information at the top, date, employer's address, salutation, 3-4 body paragraphs, closing, and signature. Keep it to one page maximum.

Formatting matters: Poor formatting can cause ATS systems to reject your application, even if the content is perfect.
