W&S bags is thinner than Glad bags, they are good for soft light trash. In one of the photos I show my hand inside the bag, I think it gives a good idea of the bag thickness. The blue bag is transparent and you can see the trash inside the bag.
Each bag length is 17 3/4" and the width is 15.5" when folded in half (31" total). Note that my measurements are slightly different from the size in Amazon description. The bag has the same width at the top and at the bottom. The bag has a draw string, which works well to close the bag when it is ready to be thrown out. The roll has 100 bags in two rolls.
