A 70-inch TV has a diagonal measurement of around 178 cm, equating to a width of approximately 157 centimeters, or 61-62 inches. The actual width of a 70-inch TV can vary depending on the brand, model, and design, but it’s safe to assume that the average width will be around 157 cm as we stated. Refer to the table above for more details, whichever form of measurement you prefer.

How wide is a 70 inch TV?

To understand just how wide a 70 inch TV is, we can simply take a look at the width from the table above. The 70-inches that manufacturers are referring to is for the diagonal measurement, so the width will be different to that. As we can see, a 70″ TV is around 61.8 inches wide, which translates to 157cm or 1,570mm for metric users.

Do take note however that this is simply measuring the size of the screen itself, ignoring and borders or additional panels such as for speakers. Many modern TVs have thin bezels and a thin frame though, so this measurement won’t be too far off the full size. Check your TV’s exact width on the product page or via the manual.

Is 70 inches too big for your house?

The rise in popularity of 70-inch TVs can be attributed to several factors. The largest is that the advancements in display technology have allowed for greater screen sizes without sacrificing image quality.

This means that you can now enjoy your favorite movies, TV shows, and video games on a larger display, with high resolution and HDR providing an experience like your parents wouldn’t even be able to imagine in their childhood.

Another reason why 70-inch TVs are gaining in status is the shift toward home entertainment. With the rise of streaming services, more and more people have been opting to create their own home theater rooms, complete with high-end sound systems, comfortable seating, and of course, massive TVs.

Is a 70 inch TV right for you?

When it comes to creating a visually stunning entertainment hub, TV is the centerpiece. A 70-inch TV is not only much larger than the average home TV, but it’s also the perfect size for creating an unforgettable cinematic environment. The huge display allows the action to fully encapsulate you, while the latest display technologies work to produce otherworldly image quality, with vibrant hues and deepest blacks.

However, it’s important to consider not only the size of the TV but also its design and placement in the room. You should aim to create a balance between the TV size and the room’s overall décor, while also optimizing for the best viewing distance.
