Your sprite is 0.9 x 1.2 when it has a scale of 1. width = spriteWidth / pixelToUnits height = spriteHeight / pixelToUnits

To give you an idea of how an orthographic's camera size works: If you have an image that you want to fill the whole screen then position the sprite directly in front of the camera and set the camera size to half of the unit height of the background sprite. Or scale the sprite so that it's height is double the camera size.
