I ordered a size large in Dickie's Women's Denim Bib Overalls (color: medium stonewash). I was immediately disappointed by the pockets. They were barely deeper than your average disappointing blue jeans! I should have tried the Carhartt's.
The two front slash pockets seem promising at 7 1/2" maximum depth and until you realize that the 6" diagonal edge reached to a minimum depth of 2". My phone sticks out (and it did manage to stay in during various bending and activities) and I can get keys in the other pocket. However, it'd be risky to try to do both keys and wallet in one pocket. I will be sewing pocket extenders on to make them more functional.
I did find the front bib pocket held my wallet securely. It's about 5" deep and 3 3/4" wide, with an adjacent pencil/pen pocket about 1 3/8" wide. The corners are rounded.
The two back pockets are perfectly acceptable at 5 1/2" deep and wide.
Finally, there are bonus pockets on each leg towards the back/side.
On the wearer's left is a single 4 1/2" deep x 3 1/2" wide under the hammer loop.
On the wearer's right is a slightly larger one at 4 1/2" deep and 4" wide. Behind it is a larger pocket with a slanted opening. It makes 8" deep and slant opening of 3 1/2". The lower part overlaps the top pocket so its lower dimensions are the same.
