50 inch vs 55 inch TV size comparison

How TV Sizes Are Measured: TV sizes like "50-inch" or "55-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.

The Difference: A 55" TV has 21% more screen area than a 50" TV — that's like adding an extra 225 square inches of viewing space!

[00:00:00] So, you're buying a TV and you're looking at a 50-in or a 55 in TV and you're probably wondering, does it matter? And it does. I'll show you why. Because while the size difference, it might seem small, it can have a big difference on your viewing experience. So, here's a calculator I built and it helps you make this exact kind of [00:00:21] decision. So, we have our 50-in 55 in. Does not look like there's a big difference, right? But let's do an overlay here. Again, not a big difference, but here's the thing. A 55-in TV, it's 21% larger than that 50in TV there. So, we look at this space here, and we're thinking it's not big. [00:00:41] But when you add all of that up, that's a big difference. And that extra screen space, that can make your content feel more immersive and enjoyable, especially when you're a little bit further back. And if you're in a tighter space, you probably want to look at the dimensions because that 21% can make it so it might not fit on the mount on the wall or your stand. And if you want to avoid some of [00:01:02] those big mistakes people make when they're buying TVs, check out our TV buying checklist as well. It's free and it'll help you get the best TV for your budget. We hope this helped and thanks for watching.

Common Mistakes to Avoid

Forgetting about stand width: A 55" 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 55" 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 55" feel small. A good rule of thumb is roughly 1.5× the diagonal — about 7 feet for a 55", 6.5 feet for a 50".

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.

50 vs 55 Inch TV: Quick FAQ

How wide is a 55 inch TV?

About 47.9 inches wide (27 inches tall) for the viewable screen on a 16:9 TV. Overall width may be slightly more with the bezel.

How wide is a 50 inch TV?

About 43.6 inches wide (24.5 inches tall) for the viewable screen on a 16:9 TV. Overall width may be slightly more with the bezel.

Is a 55 inch TV too big for my room?

It depends on viewing distance. As a quick guide, ~1.5× the diagonal works well: ~7 feet for 55". If you sit much farther, consider going larger; much closer, consider 50".

Will a 55 inch TV fit on my old TV stand?

Check the stand width (feet span). Many 55" models use wide-set feet that need a wider surface than the screen width alone suggests.
