How Big Of An Impact?

how big of

How big of is a phrase that can be used to ask questions about the size or magnitude of something. It is often used to inquire about the physical dimensions or scale of an object, but it can also be applied to abstract concepts such as importance, quantity, or enthusiasm. For example, one might ask, How big of a TV should I buy? or How big of a fan of soy foods are you? The phrase invites exploration and encourages us to delve into the specifics of a subject, whether it's a tangible item or a more abstract notion.

How big of a TV should I buy?

When it comes to buying a TV, bigger doesn't always mean better. The size of your TV will depend on several factors, including the size of the room, your budget, and your viewing distance.

The most popular TV sizes for living rooms are 55- to 65-inch models, while bedrooms or offices commonly use TVs under 45 inches. The size of your TV will also depend on your viewing distance. If you sit 7.5 feet away from the TV, for example, a 55-inch TV is the minimum screen size you should buy, but a 65-inch TV would also be suitable.

To determine the ideal viewing distance, you should aim for the TV to take up a minimum of 30 degrees of your field of view, and a maximum of 40 degrees. To calculate this, you can multiply the size of your TV by 1.2 to get the recommended viewing distance in inches. For example, a 50-inch TV would be best viewed from around 5 feet away.

You can also calculate the ideal TV size based on your viewing distance. If your couch is between six and seven feet away, a screen of around 55 inches is a good size. If your couch is seven to eight feet away, you can opt for a 65-inch TV.

It's important to note that the size of your TV will also depend on your budget, as larger TVs with better picture quality will be more expensive. Additionally, the type of display technology and resolution will also impact the price. Common display technologies include LED, OLED, and QLED, each with its pros and cons. In terms of resolution, 4K is recommended for most people, as it offers a clearer picture and allows you to sit closer to the TV without eye strain.

Ultimately, the size of your TV will depend on a combination of factors, including room size, budget, viewing distance, and personal preference.

How big is the universe?

The universe is mind-bogglingly big. In fact, it's so big that it exceeds the bounds of human comprehension. To put it into perspective, the moon is the closest astronomical object to us in the entire universe. On average, it's about 380,000 km from Earth. That's a pretty long way; nearly 30 Earths could fit side by side over that distance! The Apollo astronauts, travelling faster than any human before them, took three days to reach the moon's vicinity.

The sun is about 400 times farther away from us than the moon, at a distance of 150 million km. If you could pave a road between Earth and the sun, it would take you about 170 years to drive there at highway speeds. A commercial jet would fare better and could make the journey in 17 years.

The nearest star system to the sun is Alpha Centauri, which is 41 trillion km away. That's about 30 million suns away! The nearest large galaxy to the Milky Way is Andromeda, which is 2.5 million light-years from us. The universe is 13.8 billion years old, so you might think the most distant objects we can see are roughly that distance away in light-years. But the cosmos is expanding, and in the time it's taken for the light from distant objects to reach us, that expansion has swept them further away. Because of this movement, the observable universe is estimated to be about 90 billion light-years across.

Scientists have used statistical analysis to determine that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across. However, ultimately, science has no reliable estimate of the actual size of the entire universe.

The shape of the universe

The size of the universe depends on its shape. Scientists have predicted that the universe might be closed like a sphere, infinite and negatively curved like a saddle, or flat and infinite. According to NASA, the universe is flat with only about a 0.4% margin of error (as of 2013). This suggests that the universe is infinite in extent. However, since the universe has a finite age, we can only observe a finite volume of it.

The observable universe

The observable universe is a ball-shaped region consisting of all the matter that can be observed from Earth or its space-based telescopes and exploratory probes. This is defined by the physical limit created by the speed of light itself. No signal can travel faster than light, so there is a maximum distance, called the particle horizon, beyond which nothing can be detected as the signals could not have reached us yet. The radius of the observable universe is estimated to be about 46.5 billion light-years, making the diameter about 93 billion light-years.


How big is infinity?

Infinity is a boundless, endless concept, larger than any natural number. It is often denoted by the infinity symbol: ∞.

The philosophical nature of infinity has been a topic of discussion since ancient Greece. In the 17th century, with the introduction of the infinity symbol and infinitesimal calculus, mathematicians began to work with infinite series. However, it remained unclear whether infinity could be considered a number or magnitude.

In the late 19th century, German mathematician Georg Cantor enlarged the mathematical study of infinity by investigating infinite sets and infinite numbers, demonstrating that they can differ in size. For instance, the infinite number of points on a line is greater than the number of integers.

Cantor's work revealed that there are infinite levels of infinity, with one infinitely large group potentially being larger than another. This concept is known as "cardinality". The cardinality of the natural numbers, or the counting numbers, is denoted as "aleph nought". Cantor proved that the set of real numbers, which includes all rational and irrational numbers, is larger than the set of natural numbers, with a cardinality of "aleph one".

The list of alephs, representing the sizes of infinite sets, goes on infinitely, indicating that there are infinite sizes of infinity. This discovery led to the continuum hypothesis, which posits that there is no cardinal number between the cardinality of the reals and the natural numbers.

While the concept of infinity may seem abstract, it has practical applications in mathematics and physics. Infinity is widely used in areas such as combinatorics, and Wiles' proof of Fermat's Last Theorem relies on the existence of very large infinite sets. In physics, the concept of infinity is relevant in cosmology, where it is an open question whether the universe is spatially infinite.

How big of a TV can fit in my room?

When it comes to choosing a TV, bigger isn't always better. The best television for you depends on several factors, such as room size, budget, and viewing distance.

TV Viewing Distance Formula

The Society of Motion Picture and Television Engineers (SMPTE) recommends that a TV should take up a minimum of 30 degrees of your field of vision. This means that if you sit 7.5 feet away, the minimum screen size is 55 inches, but a 65-inch TV would also be suitable.

To calculate the ideal screen size, you can measure the distance between your seating and the planned location of your television and divide it by three. For example, if your couch is 120 inches from the TV, your screen size should be at least 40 inches.

TV Resolution

The resolution of a TV refers to the number of pixels that make up the image on the screen. The more pixels, the sharper the image, and the closer you can sit without distortion. Common resolutions include Full HD (1920 x 1080), 4K Ultra HD (3840 x 2160), and 8K Ultra HD (7680 x 4320).

A 4K TV has pixels that are a quarter of the size of a 1080p TV, so you can sit closer without experiencing eye strain. This means that a 4K TV is a good option for smaller rooms where viewing distance is limited.

Room Size and Position

The layout and size of the room are crucial factors when choosing a TV. Even if you want a large TV, it may not fit or provide a comfortable viewing experience in a small, narrow space.

If you plan to use a stand, the TV will be closer to the viewer, whereas wall-mounting can add a foot or more to the viewing distance, allowing for a larger model. The TV should be straight and at eye level, and if wall-mounted, not too high to avoid neck strain.


Larger TVs with higher resolutions will generally be more expensive. If your budget is limited, you may need to opt for a smaller screen size or a lower resolution.

Other Considerations

When choosing a TV, it's also important to consider the stand width, especially if you plan to mount the TV on a console table. The stand legs may be wider than the screen, so ensure they will fit on your TV stand.

Additionally, if you have a media cabinet with an existing TV opening, measure the diagonal opening to ensure the TV fits with enough clearance for any rear or side connections.

How big of a TV should I buy based on viewing distance?

When it comes to buying a TV, there are a few factors to consider to ensure you get the optimal viewing experience. The size of your TV will depend on your budget, the size of your room, and how far you plan to sit from the screen.

Viewing Distance

The viewing distance between you and the TV is an important factor in determining the ideal TV size. As a rule of thumb, the further the viewing distance, the bigger your screen size should be. The viewing distance can also depend on the type of content you'll be watching. If you intend to watch 4K Blu-ray movies, you may want a TV size with a viewing angle closer to 40°. If you're watching 1080p television shows in a living room where aesthetics are a concern, you may prefer a TV with a viewing angle closer to 30° or even less.


The resolution of your TV will also impact how far you can sit from the screen. TVs with higher resolutions, like 4K or 8K, have smaller pixels that are harder to see at the same distance. This means you can sit closer to a 4K TV than you could a 1080p TV before you start to see the pixels. The higher the resolution, the closer you can sit before you notice pixelation in an image.

Budget and Room Size

Of course, your budget and the size of your room will also play a role in determining the size of your TV. Larger screens and higher-resolution displays tend to cost more. If you have a smaller room, you may not have the space for a very large TV, and you'll need to consider the available wall space or entertainment unit size when making your decision.

Calculating the Ideal TV Size

There are a few formulas and guidelines you can use to calculate the ideal TV size based on your viewing distance. The Society of Motion Picture and Television Engineers recommends that a TV should take up a minimum of 30° of your field of view. This means that if you sit 7.5 feet away, for example, the minimum screen size you should buy is a 55-inch TV. You can also use the formula: Viewing distance (in inches)/2 = recommended TV size. So, if you sit 10 feet away, which is 120 inches, a 60-inch TV would be recommended.

In summary, to get the optimal viewing experience, consider your budget, room size, viewing distance, and the resolution of the TV. Use the guidelines and formulas provided to calculate the ideal TV size for your setup, and don't forget to also take into account your personal preferences and the type of content you'll be watching.
