10.5” Long (excluding handle) X 8.5” Wide X 5.5” deep. Bag width is measured according to base. So the base is 8.5” wide, but it does expand around sides. There’s extra material to form the shape of the bag. It also buttons on each side. Very cute and classy backpack. 😻 I love the color of the leather, it makes it look more expensive. It has an exterior zip pocket on back, interior zip pocket and 2 open interior pockets. Leather is in great shape but some darkening on inside of handle, very minor scratching here and there, rubbing along corners. I look for flaws so I notice them but they’re really not noticeable if you’re not looking for them. Interior is in great shape, no pen marks or stains. Straps and hardware look great. No weird smells. It’s ready to be yours!
