[00:00:00] So, if you're not sure whether you want to get a 77 or an 85 in TV, that 8 in jump, it is actually a pretty big jump and it comes with some real trade-offs. Let's take a look at that. So, first, here's our 77in screen and here's the 85 in screen. Watch when we do the overlay. When we overlay that 75 on the 85 in TV, [00:00:22] you see that the 85 in TV is 22% more viewing area than the 77 in. And that is a big difference, especially when we compare them side by side here. Note when you move up to that 85 inch TV, it is a much heavier TV. It's also wider, so you need to make sure that it's going to work in your space. And the box is bigger, so you're going to have to think [00:00:42] about transport. In this case, both are pretty big. If you can get free delivery, I really recommend that. Here's a pricing detail that actually surprises a lot of people, though. In many TV lineups, that 77in model, they're more premium TVs. This means they have better panel technology, higher-end processing, and more advanced [00:01:02] features. Because of that, you may actually see some 77in TVs cost more or as much as than these 85-in models. That's because there are more mid-range and entry-level options in the 85 in range. So, the decision really isn't just about size. It's also about what type of TV you're buying and what you [00:01:22] want that TV to do for you. So before you pull the trigger on that 85 or 77in TV, jump over to TVsimplify.com, try our calculator, and subscribe here if you want more tools and quick guides like us.

Common Mistakes to Avoid

Forgetting about stand width: A 85" 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 85" 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 85" feel small. A good rule of thumb is roughly 1.5× the diagonal — about 10.5 feet for a 85", 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.

Is a 85 inch TV too big for my room?

It depends on viewing distance. As a quick guide, ~1.5× the diagonal works well: ~10.5 feet for 85". If you sit much farther, consider going larger; much closer, consider 77".

Will a 85 inch TV fit on my old TV stand?

Check the stand width (feet span). Many 85" models use wide-set feet that need a wider surface than the screen width alone suggests.
