How do I get the right aspect ratio to make a profile photo on social media?

I think you want to change your “profile photo” to be a square, rather than a rectangle. The common aspect ratio of a square image is 4:3, but you could also resize a photo to the desired size.

Can you explain why the aspect ratio is 4:3 for a square?
user
Well, a square is a rectangle where the width and height are equal.  By definition, this would be a rectangle with sides of length 1.  It sounds like you want to know why the “aspect ratio” of this rectangle is 4:3.  The aspect ratio of a rectangle is the ratio of its width to its height, and the aspect ratio of a square is the same as its width-to-height ratio, which is 4:3.

So is this the same aspect ratio I should set my camera to?
