Typical Cover Letter Length. A cover letter should be as brief as possible generally two or three short paragraphs. Check with faculty in your department.
Think of your resume as an outline of your career and the cover letter as the description. What about academic cover letter length. Include attention grabbing yet professional information.
A general cover letter ranges from 300 to 500 words.
If you make your cover letter too long the recruiter wont read it. You want to use a layout that makes your letter both easy to read and professional. Before starting your cover letter check whether the hiring manager has set a cover letter work length in the job description. If its word count is too low though your cover letter will look sloppy.
