How long it takes to write a cover letter depends on:
- how comfortable you are with writing
- if you have experience writing cover letters
- how much you want the position (you should devote more time to jobs you’re more interested in)
But to maximise the number of cover letters you send out while making sure each one is well-written and customised, plan to spend roughly 1 hour per cover letter. One way to write a cover letter in 1 hour is to split your time evenly among researching the company, writing the first draft, and editing your cover letter.
