65 inch vs 70 inch TV size comparison

How TV Sizes Are Measured: TV sizes like "65-inch" or "70-inch" refer to the diagonal of the viewable screen, corner to corner. These measurements exclude the bezel and the stand, so the total physical footprint will be slightly larger.

[00:00:00] If you're debating between a 65 and a 70in TV, that 5-in jump, it does make a difference. But there's something you need to know about 70-in TVs. I'm Dr. B. I make content and tools to help you with the TV buying process. So, first we're going to visualize that 5-in jump, and then we'll talk about that 70-in TV. [00:00:20] Let's go. So, first the visuals. Here's your standard 65-in screen, and here's a 70in screen. When we overlay them, moving up to that 70-in TV, that does give you 16% more viewing area than the 65-in TV. It's not a huge difference, but it does matter when you're deciding what TV [00:00:40] actually makes sense for you. If this calculator is helping you figure out which TV is best for you, or you're still deciding, feel free to subscribe. One caution with logistics. Even a 5- in increase changes the overall width and the height of the TV. And this can affect whether it'll fit on your furniture or line up with your wall mount or even just work in your space. [00:01:02] Also, the box is a little bit larger, so it's worth checking transport if you want to take it home in your car. So, in terms of viewing experience, that 70in, it is a little more immersive. That's 16% more viewing area, but it's a subtle upgrade. It's not dramatic. Here's the thing about 70-in TVs, though. In general, 70-in TVs are kind of a [00:01:22] lower-end TV, more an entry-level TV. They're big, which is nice, but they usually lack features. You don't have a lot of choices what kind of features you'll get if you're looking for a 70-in TV. So, I'd recommend looking at a 65 in or maybe a 75. See if it might be better fit. So, before you pull the trigger, [00:01:43] get the bigger screen. Jump over to tvsimplify.com, try our calculator, and subscribe if you want more tools and quick guides like this.

Common Mistakes to Avoid

Forgetting about stand width: A 70" 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 70" 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 70" feel small. A good rule of thumb is roughly 1.5× the diagonal — about 9 feet for a 70", 8 feet for a 65".

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.

65 vs 70 Inch TV: Quick FAQ

How wide is a 70 inch TV?

About 61 inches wide (34.3 inches tall) for the viewable screen on a 16:9 TV. Overall width may be slightly more with the bezel.

How wide is a 65 inch TV?

About 56.7 inches wide (31.9 inches tall) for the viewable screen on a 16:9 TV. Overall width may be slightly more with the bezel.

Is a 70 inch TV too big for my room?

It depends on viewing distance. As a quick guide, ~1.5× the diagonal works well: ~9 feet for 70". If you sit much farther, consider going larger; much closer, consider 65".

Will a 70 inch TV fit on my old TV stand?

Check the stand width (feet span). Many 70" models use wide-set feet that need a wider surface than the screen width alone suggests.
