The front pockets are 2.5" at the side seam and about 6" deep at the front edge of the pocket, which is also the deepest point of the pocket. The pocket is connected to the waistband such that there is an odd little section of the pocket that continues over to the zipper (visible in photo). This should keep the waistband from distorting if you put anything heavy in, though since these are sturdy jeans it may not matter anyway. My hands fit in mostly, keys and wallet are secure together in one pocket (though tight), and my phone makes it most of the way into a front pocket by itself (it doesn't seem in danger of escaping).

The right front side has an additional pocket about 2.25" wide and about 3" deep. I've never used it. The two back pockets are each about 5.25" from edge to deepest point, typical jeans pockets.
