Inventory UI Not Filling Screen.

Thanks for your answers. Ik about the resolution thing you told me, i thought about it. I tried using anchors at first so it can fill the screen. So i added a canvas panel like this: Imgur: The magic of the Internet and set the anchors of the size box to fill screen. But it didn’t seem to work because of this: Imgur: The magic of the Internet. If you know some fix about this that would be amazing. Thanks again for everything :D!
