The wallet is slightly longer than a credit card, and the thickness with everything I have in it (one credit card, one debit card, my license, insurance cards, and a couple store saver cards) is about as thick as my iPhone 7 with its case.  It holds everything securely and can easily fit in the front pocket of my jeans or dockers.  My only suggestion for improvement would be to make it a bit longer so the center compartment can hold more.  For those who carry cash, it would be a bit of a pain because the center compartment is really the size of a credit card so you have to fold whatever cash you put in it, and you are realistically looking at only a few bills being able to fit in it.  For those who do not carry cash, however, it is just fine.
