Another great way to save some space for important information is to play with the spacing of your application document. If you have two spaces between every heading, you may change it to one space. Moreover, you can use another font as some fonts come smaller than others. For instance, Times New Roman font is smaller than Arial.
All in all, there is no perfect resume length that will be suitable for everyone. You may search about how long should a resume summary be but still the length of the resume will depend on several factors. Depending on your level of expertise and work experience, you can choose the best option and make a resume that will outshine the competition and win you a job interview.
