[00:00:00] So, let's do this. Let's compare a 77in TV to an 83in TV. And at first, it doesn't look like there's really much difference. But if we overlay the 77 on top of the 83in TV, watch this. That 83in TV, it does have 16% more [00:00:21] screen area than the 77in TV. And remember, these are big TVs starting out with. So, 16%, that's a big jump. And you're going to have to think about a few things. If you bump up to that 83in TV, it is going to be a bigger TV. You're going to need to check your furniture, your wall mount, make sure that it's actually going to fit in the space where you're watching. And also [00:00:43] note, because it is going to be bigger, it's going to cost a little bit more. But in some cases, that 16% viewing area, that's going to be worth the bump up. If the space works out and you can mount it on the wall or put it on a stand with your furniture, maybe that's a good deal. But one thing you got to watch out for is what features you end up getting with these TVs because [00:01:03] ultimately that really affects your viewing experience too. So watch the next video, make sure you get that right.

Common Mistakes to Avoid

Forgetting about stand width: A 83" TV's feet can span well beyond the screen width. If your stand or furniture is too narrow, the feet will overhang or be unstable. Measure your stand's usable width before buying.

Ignoring the box size for transport: The packaging for a 83" TV is significantly larger than the screen itself and often too large for most vehicles. Measure your vehicle's opening before buying, or arrange for store delivery.

Underestimating viewing distance: Sitting too far away makes even a 83" feel small. A good rule of thumb is roughly 1.5× the diagonal — about 10.5 feet for a 83", 9.5 feet for a 77".

Not accounting for bezel and stand dimensions: The actual footprint with stand is larger than the screen alone. Measure height, depth, and leave 2–4 inches of ventilation clearance if placing in a cabinet or entertainment center.

Underestimating adaptation to larger screens: Many buyers report that a TV that feels "too big" at first quickly becomes normal, leading to regret for not going bigger. If both sizes fit your space and budget, choose the larger.
