I thought this bag was bigger but honestly it's even better than what I was expecting. (No, I did not check the dimensions ;P) I am using it as a bag for work and it fits all my essentials. I use the laptop pouch for my planner and pencil case, but it fits my laptop and tablet too if needed. It has lots of pockets which I love. I use the side pockets for pens and a fairly large umbrella. The size is really nice- it could be used as a purse if desired. The inside color is really pretty too. I love the material on the outside- it is waterproof, so it's perfect for places that rain a lot.
