Easiest way to import a simple 2d shape from photoshop and have it be a 1/1/1 scale in unity.

I’m a solo programmer working on a game so I’m making very simplistic art assets like triangles and squares in photoshop for my game but whenever I implement them they are way too big so far my only solution has been to increase the pixels per unit and even then its not perfect, is there a way to set my sprites to the exact same size as the basic unity ones?

hm maybe this information is usefull for you: 1 unity unit or a vector3(1,1,1) is 1 meter / 1m3

so 1 meter is in photoshop: 377.9527559055 pixels
