If it;s IT your looking for, then dont worry too much about length as if you have loads of tech skills or experience of different systems you need to name them all, so the relevant skill gets spotted. I do lots of hiring of IT staff and i get suspicious of short cv's and always like a long list of largely unknown skills.
All very well but it's very very obvious when people are telling porkies by listing C, Java, C#, PHP, ASP, Python, Fortran, Assembly, CSS, ASP classic followed by the dreaded "exposure to" and list yet another buttload of acronyms. We pass these CVs around the office pissing ourselves laughing. Much better to not bullshit, or if you are insistent on bullshit be a tad more realistic.
