The actual size is 13 in high , works for carrying i pad mini up to the 9 in i pads . Love the fact that its lightweight, and can hold up against a heavy down pour of rain. I carry a change of clothing,a snack, wallet,i phone 6s plus,meds, and some small items,travel hair brush,ect. I am 5'6 retired walks with a cane. the bag is just the size backpack I have been looking for I brought for traveling light. But will use to run errands around town.Note if you put a change of clothing in the bag, you can not put a light jacket in as well it is one or the other. This bag works for me for what I need it to do. Thank you Timbuck 2 for coming up with a small backpack.
