How long is an "Ideal" resume?

Here's more advice from Keppie Careers on how long is a LONG resume.

Many hiring managers still prefer a one-page resume. However, if your industry tolerates longer versions, one rule of thumb is that your resume should not exceed one page if you have less than 10 years of experience. If you have more experience, a two-page resume may work. Typically, our bias is that your resume should be one page unless there is a specific reason for it to be longer.

Electronic resumes do not have page limits, but you still want to hone your materials to effectively target your key skills relative to the job.
