Top-down 2D game, UI element resolutions.

Hey guys, I’m currently in the process of making a top-down 2D game and I’m having a hard time understanding exactly what resolution I should (or can) make various elements for the game.

We’re building the game using 32x32 assets and tiles but things such as UI elements are a bit confusing to me. How do I know what resolution to make things like inventory frame, inventory slots or character panel with equipment slots etc to make sure it scales properly up/down in different resolutions? Ty!
