Why 120 inches changes the room
You need more than the extra 17.4 inches of image width. You also need frame clearance, wall margins, enough furniture depth for the projector's 120-inch throw position, and enough seating distance to avoid an overwhelming image.
Why 100 inches is often easier
A 100-inch setup fits more walls, demands less projector-to-wall distance, and leaves more room for speakers or furniture. It can also look brighter from the same projector because the same light output is spread across less area.
Why 120 inches can be worth it
If the wall and throw geometry work, 120 inches creates a visibly more cinematic field of view. The larger surface is one of the strongest reasons to choose a projector instead of a large TV.
