How short is your resume? As long as it has all the necessities in it (personal details, education details, work history, references) than that is all you need. Employers don't want to read through 4 or 5 pages of crap, they want to get to the point, what can you offer them, what are your experiences.
Same goes for cover letters. Intro, Body and Conclusion. Intro to introduce yourself, the job you're applying for. The body to explain what you can offer the employer and why you believe you can do the job. Concluded with your contact details.
Keep it simple and to the point.
And good luck with job hunting.
