It's bigger than the picture depicts.  I have a 17.3 inch Acer that fits just perfectly.  More room for books, maybe a binder. Has an additional zipper up front for small things as well. Inside has a velcro strap to hold your computer in place. Also it's sectional inside. In addition, there's zippers on the side to hold a drink. Buy it, it's worth every cent.<a data-hook="product-link-linked" class="a-link-normal" href="/Mobile-Edge-Express-Pink-Ribbon-Backpack-MEBPEX1/dp/B0016BAU9I/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Mobile Edge Express Pink Ribbon Backpack (MEBPEX1)</a>
