SOLVED - Camera Size to show sprite properlly

Question

Hello,

I'm making a 2D game for mobile devices. I've my camera set as Ortographic, size 5 and resolution on Game tab as 720x1280.

When I drag a sprite of size 720x1280 and 100 pixels per unit (to be my background of my scene, it appears bigger than the camera. I saw online that a corelation with camera size, height of a block in pixels and resolution does exist, but I couldn't understand.

I just wanna fit my background without having to scale it by hand.

The orthographic camera size was also a bit confusing to me when I started learning Unity. After stumbling about the internets looking for answers, I happened upon this post on the Unity blog that explained it pretty well and it clicked for me. Hope it can help you as well. :)

Thanks, @ricke44654 ,

Actually, I figured it out by other ways, but the link you shared with me helped a lot more.

Saw online a equation to calculate the size of ortographic camera and I found that, for the resolution I wanted, the pixels per unit I wanted, it has to be bigger. The equation is Ortographic Size = Desired Height / (2 * pixels per unit) . I guess everyone has checked a site that said that, but I didn't know how to use, bechause, otherwise of putting "pixels per unit" they named it differently.

Oukei. Now I'm making it fullHD and the Ortographic Size is 9.6.

I'm making a game in 1920x1080 and the ortographic size is 5.4 and matches perfectly according to the formula. Thanks :)
