Gravel and sand are very different media and two inches of sand will easily match three inches of gravel in weight. Sand holds plants down better but also prevents water from circulating anywhere as easy compared to gravel (even a thicker layer of gravel); so I'd think that sand should be thinner if you want to allow diffusion of water/plant food into it and out of it.Knowledge is fun(damental)
A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

Most people taper the depth from the front to back. Small foreground plants (generally with smaller roots) can be in 2" sand up front and then the larger plants (such as amazon swords with massive roots) can be in the back in 3-4" sand.
