How to remove unwanted area outside of the Canvas area in Photoshop?

Hi all,

I'm new to Photoshop, so seeking help here as I couldn't find the solution even after searching the internet.

My question is - how do I remove this unwanted area that I have marked in red in the below screenshot , i.e. the area outside of canvas?

That is, I want the white canvas should also stretch & coverthe entire area including the red area.. is it possible?

Can someone please help in this regard? :rolleyes:

are you using an artboard rather than canvas; you cannot draw outside of a canvas, but you can with an artboard....
