About 2.5 inches depth overall (meaning, evenly when you first put the washed gravel in the tank). You can then build it up slightly deeper in the back (and consequently shallower along the front, maybe 1 to 1.5 inches) by using rock or wood. The larger-rooted plants will be in the back and this gives them more depth.
What sort of gravel? By 7mm do you mean that each particle of gravel is 7mm in width? This is pea gravel, which can work but not as well as a finer gravel with a grain size of 1-2 mm.
