一個似乎昂貴的大電視確實提高了觀看質量。但是，雖然大電視，像65英寸，聽起來很好，它真的適合你的家嗎？要了解某些情況，您必須測量電視的尺寸。
A 65-inch TV with a 16:9 aspect ratio typically measures 56.64 × 31.86 inches (143.87 × 80.92 centimeters) and occupies a total area of 1,804.55 square inches (11,641.96 square centimeters).

How Large is a 65-inch TV?
As soon as you take a look at a TV, the marketed size will pretty much reveal everything you need to know about it. For instance, a 65-inch TV measures around 65 inches (165.1 centimeters) diagonally.
然而，這一數字在知道它將使用的牆上的空間有多少錢時，這真的沒有多少幫助我們。要找出總區，我們必須測量其高度和寬度。
但在we get into that, we first have to familiarize ourselves with aspect ratios.
寬高比
The aspect ratio is the ratio of a display’s weight to its height. Aspect ratios can be found in any device that has a screen—e.g., smartphones, smartwatches, monitors, laptops, etc.
The aspect ratios for TVs and monitors that you’ll commonly come across are as follows:
- 4:3
- 16:9
- 21：9
To give you an idea of what these figures mean, a TV screen with a 21:9 aspect ratio means that for every 21 inches horizontally, the screen will measure 9 inches vertically.
From the aspect ratios listed, unless you plan on purchasing an ultra-wide TV, its aspect ratio will most likely be 16:9. So, for the following calculations, we’re going to assume that the TV you have your eye on has a 16:9 aspect ratio.
Calculating Screen Size
There are three important formulas to bear in mind when measuring the physical dimensions of a TV. Those formulas are as follows:
- H = D÷√（AR2 + 1）
- w = ar×h
- a = w×h
Assuming you want to pick up a 65-inch TV with a 16:9 aspect ratio, we can start by calculating the height of the TV.
- H = D ÷ √(AR2 +1)
- H = 65 ÷ √(16:9)2 +1)
- H = 65÷√（3.16 + 1）
- H = 65÷4.16
- H = 65÷2.04
- H = 31.86 inches (80.92 centimeters)
現在我們有電視的身高，我們可以將其輸入到寬度公式中以得到以下內容：
- w = ar×h
- w = 16：9×31.86
- W = 1.78 × 31.86
- W = 56.64 inches (143.87 centimeters)
在確定高度和寬度之後，我們可以將兩個乘以計算總麵積。
- a = w×h
- a = 56.64×31.86
- A = 1,804.55 square inches (11,641.96 square centimeters)
Basically, a 65-inch TV with a 16:9 aspect ratio screen will measure roughly 56.64 × 31.86 inches (143.87 × 80.92 inches) and take up a total of 1,804.55 square inches (11,641.96 square centimeters) of wall space.
Assuming the 65-inch TV has an aspect ratio of 4:3, its screen measurements would be 51.99 × 38.99 inches (132.05 × 99.03 centimeters) with a total area of 2,027.09 square inches (11,206.57 square centimeters).
If the TV had a 21:9 aspect ratio, its screen measurements would be 59.74 × 25.60 inches (140.06 × 65.02 centimeters) while covering 1,529.34 square inches (9,106.70 square centimeters) of a wall.
65-inch TV Viewing Distance
所以，你已經設法將65英寸的電視帶回家裏的一件。對你有益！下一步是決定相對於你的沙發或座位安排將其放置多遠。
您可以參考索尼的電視觀看距離上的索尼指南，但我會在下麵短暫拆分：
- For 4K and beyond TVs, multiply by 1.5 times the distance of the TV’s height (47.79 inches or 121.39 centimeters for a 65-inch TV)
- For HD TVs, multiply by 3 times the distance of the TV’s height (95.58 inches or 242.77 centimeters for a 65-inch TV)
- For Standard Definition TVs, multiply by 6 times the distance of the TV’s height (191.16 inches or 485.55 centimeters for a 65-inch TV)
65-inch TV Television Placement
Mounting Height
電視屏幕中心應在坐姿時放置在類似的眼睛水平水平。如60英寸電視維度指南中所討論的，計算平均安裝高度，從平均眼睛水平（42英寸）中減去65英寸電視高度（31.86英寸）的一半。
42“ - （31.86”÷2）= 26.07英寸（66.22厘米）
This is an approximate number based on an average adult’s height. Adjust it to your own comfort levels when seated in front of the TVs.
TV Stand Height
If you decide to use a TV stand instead, you can subtract another 2 or 3 inches, which is the distance from the TV screen’s bottom to the TV’s legs.
In this case, the approximate number for a TV stand to work with a 65-inch TV is 26.07 inches – 2 inches = 24.07 inches (61.14 cm)
What Size Room Do I Need For a 65-inch TV?
這將考慮到一些標準，例如使用的電視類型和電視的角度。
If you get an HD 65-inch TV, the viewing distance suggestion is 3 feet 11 3/4 inches. The room size should be of minimal 5 feet.
與此同時，您應該從椅子或沙發上放置4千英寸7英寸11 5/8英寸。如果是這樣，房間長度或寬度需要至少10英尺。
