I think a sheet would be 4 crackers (rectangle) rather than 2 (square). See, this is why weight is
so nice. But until this is resolved, I would make half a basic graham cracker pie recipe and put any leftover crumbs in the freezer.
King Arthur 9" graham cracker pie crust:
1 1/4 cups graham cracker crumbs
2 tablespoons granulated sugar
6 tablespoons butter, melted (3/4 stick)
Spread in lightly sprayed 9" pie pan.
Bake 350 for 6-8 minutes. Don't overbake. It will harden more in the refrigerator.

*To make an almond graham crust, use 2/3 cup almond flour and 2/3 cup graham crumbs, along with the butter and sugar. Bake as directed.
