Narrower FOV with 85mm means smaller screen needed even at same distances.
For a headshot: 5×7 ft minimum. Waist up: 7×9 ft. Full body standing: 10×12 ft. Full body with movement: 12×14 ft. Always bigger than your framed area plus 20% margin for movement.

Minimum 6 feet (2m). Ideal is 8-10 feet. More distance = less green spill on subject and more even lighting. Too close causes green color reflecting onto skin and clothes.
Use two soft lights aimed at the screen from 45-degree angles. Screen should be 1-2 stops brighter than shadow side of face but not overexposed. Use a light meter or histogram to check evenness across the screen.
Use 50-85mm for portraits (less distortion, easier to fill frame). 35mm for full body in tight spaces. Wider lenses require larger screens. Longer lenses compress distance and reduce required screen size.
