43 inch vs 50 inch TV size comparison

And by [00:00:45] the way, if you're shopping for a TV, you want to avoid those common mistakes, I put together a free checklist link below. But do be careful.

And remember, it weighs more, too. So, check the dimensions. That's really important. So, if you're shopping for that perfect TV, check out our checklist to help you make the right choice. Link below. And thanks for watching.

Common Mistakes to Avoid

Underestimating viewing distance: Sitting too far away makes even a 50" feel small. A good rule of thumb is roughly 1.5× the diagonal — about 6.5 feet for a 50", 5.5 feet for a 43".

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.

43 vs 50 Inch TV: Quick FAQ

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.

How wide is a 43 inch TV?

About 37.5 inches wide (21.1 inches tall) for the viewable screen on a 16:9 TV. Overall width may be slightly more with the bezel.

Is a 50 inch TV too big for my room?

It depends on viewing distance. As a quick guide, ~1.5× the diagonal works well: ~6.5 feet for 50". If you sit much farther, consider going larger; much closer, consider 43".

Will a 50 inch TV fit on my old TV stand?

Check the stand width (feet span). Many 50" models use wide-set feet that need a wider surface than the screen width alone suggests.
