Just say i want to make a poster that is 50cm x 50cm

How big do i make the pixel size for the drawing i make on photoshop.

If your confused, i mean, you know when you open a new file, it asks you how many pixels you want it.

Do i make the file 50 pixels by 50 pixels .. ?

Thanks guys.

u choose cm instead of pixels that will make it hella lot easier..
