I have been trying to make an inventory. The issue I am having is that when I add the Buttons (created in a separate widget) to the grid panel on my main HUD, the engine scales them way to small in game.
Can’t see the other aspects of it, but I’ve seen that happen when using “size to content” when there is no content inside of it, hope this helps
That seemed to solve the issue! However, now it makes them way to big 
**Too anybody else 10 years from now who finds this! **
Solution:
Take the Image that is a child of the button and use the “Make Brush from Texture” node. Set the width and height to the correct size.
