Combine the graham cracker crumbs, sugars, and salt in a medium-sized bowl and mix well to blend.
1¾ cups graham cracker crumbs, 2 tablespoons granulated sugar, 2 tablespoons brown sugar, ¼ teaspoon kosher salt
Drizzle the butter over the crumb mixture and mix until all crumbs have been coated with the butter. The mixture should look like wet sand.
½ cup unsalted butter
Pour the crust mixture into a pie pan or springform pan and spread in an even layer. Use a flat-bottom measuring cup to press the crust firmly in the pan and partially up the sides of the pan.

Notes
To make the graham cracker crumbs, you can just use a rolling pin to crush them while they're still in their original packets (or another plastic bag). You can also put graham cracker pieces in your blender or food processor and crush them up by pulsing in short bursts.
Storage: Store homemade graham cracker crust tightly covered in the refrigerator for up to 3 days or in the freezer for up to 3 months.
