Maximum length of a bullet point on a resume?

Do Follow the 5/5/5 rule. To keep your audience from feeling overwhelmed, you should keep the text on each slide short and to the point. Some experts suggest using the 5/5/5 rule: no more than five words per line of text, five lines of text per slide, or five text-heavy slides in a row.

Edit:

Oops, I read presentation though it clearly says Resume. I would say no more than 1.5 lines, two at most - better for them to ask questions about something than have them skip it becuause its too long

2 lines per bullet point and probably no more than 5 bullet points if you can help it. I have a resume template that I devised for b-school applicants and students that I devised from my days as a resume coach at the Stanford Business School: it's at this link, under "free download" http://admittedmba.com/downloads/index.php

If you feel like you need to place a period within the text to break it up, it's probably too much for one bullet
