Portrait photography studio size

The height of the room should not be less than 2.5 meters (background cloth should be hung, and ceiling lamps should be added if necessary), the width should be greater than 3 meters (because background cloth and cloth lamps should be added), and the length should be greater than 5 meters. If you want a full-length portrait, you need to increase the length. At this length, you can also use a 35MM lens to illuminate the whole body, but it is slightly deformed.
