How Do I Shorten My Resume to One Page?

Dear Experts, I'm having trouble keeping my resume to just one page. I have a lot of relevant job experience for the position I'm applying for and don't know how to cut it down. Are there any 'rules-of-thumb' to follow in this situation? Here is how our T.A.P. experts answered this question:Q#328 No absolutes re: resume length, but succinct=good! Trim 1 word at a time/see what overlaps, is extra. (@keppie_careers) Q#328 Tons of opinions, but no rules. I say only go over 1 pg if you have 10+ yrs exp. If not, put highlights. (@beneubanks) Q#328 1-pg rez wd have summary profile, 2-4 bullet accomps 4 2 most recent jobs & co/title 4 rest + ed, awds. (@juliaerickson) Q#328 If u have 10+ yrs exp 2 pg rez is fine. less than 10, 1 1/2 pg OK. Either MUST use READABLE font size. (@juliaerickson) Q#328 I would include either the three most relevant positions, or the last three in reverse chronological order. (@gradversity) Q#328 Summarize exp in categories at top & put total yrs next to each one. Shorten bullet points to 1 line too. (@jtodonnell) Q#328 There are no rules re: paging. 2 pages ok as long as info. is relevant. (@DebraWheatman) Our Twitter Advice Project (T.A.P.) is no longer an active campaign.
