Here's how to know if your TV is too big for any room
The instant you see a 75-inch panel on sale, the "go big" instinct kicks in hard, and that's exactly where most rooms go wrong. A screen that looked thrilling in a bright, cavernous showroom can swallow a modest living space, and once it's hung it's not a five-minute fix to undo. The article's real point is that size is a relationship between the display and the room it lives in, not a number you chase in isolation.
Where I'd want more depth is the practical side: what's the workable rule for matching screen size to seating distance, and how do wall proportions factor in when the TV isn't the only thing in the room? The viewing-science side is well documented, but the aesthetic judgment is harder to codify. A TV can be technically right for the distance and still feel overwhelming because it crowds the furniture or shouts louder than the decor.
I've seen the failure mode from the other direction too, where people buy conservative and end up squinting from the couch. So the real skill is reading the room, not the spec sheet. If the article delivers a clear test for "too big," it's worth the read; if it just tells you to consider the room, that's table stakes.
