Are you unsure about how to measure your TV correctly? Many people confuse the screen size with the overall dimensions. Knowing your TV’s size is crucial for proper mounting and ensuring the best viewing experience.
In this post, we’ll explain how to measure your TV accurately. We’ll also clarify common misunderstandings and help you choose the right TV mount for your space.
TV size refers to the diagonal measurement of the screen, not the width or height. It’s calculated from one corner of the screen to the opposite corner. The screen size is usually listed in inches, making it easier to compare different models.
To measure your TV’s diagonal size, grab a measuring tape or a ruler. Start from one corner of the screen (top-left or bottom-left) and measure straight across to the opposite corner. Be sure not to include the bezel or frame, just the visible screen area.
It’s important to measure in a straight line. Make sure your tape measure is properly aligned across the screen to get an accurate measurement.
Measuring your TV screen is an essential step for determining the right fit for your space or choosing the correct TV mount. There are several ways to do this, whether you rely on the manual, check the label, or measure it manually. Here's a breakdown of four effective methods.
Where to Find the TV Size:
Your TV's user manual is the first place you should check for its screen size. Most manuals clearly list the screen size in inches on the front pages, along with other key specifications.
How to Access the Manual Online:
If you’ve misplaced the physical manual or it didn't come with the TV, don't worry. You can easily find the digital version online. Here's how to do it:
Visit the manufacturer’s website.
Go to the support or help section.
Look for a search field where you can enter the model number of your TV.
Enter the model number (usually found on the back or bottom of the TV).
Download the PDF version of the manual, and find the screen size listed in the technical specifications section.
This is a quick and reliable way to get the information you need, and it’s often the most accurate source.
What Information to Look for:
If you can't find the manual or prefer a faster solution, check the back of your TV. There’s usually a label or sticker attached to the device that contains valuable details, such as:
Model number
Serial number
Screen size (in inches)
The model number is particularly helpful. If the screen size isn't printed directly on the label, you can use the model number to search for the specifications online. Many brands provide detailed product information on their websites using the model number.
The serial number is unique to your TV and may help if you need customer service or technical support.
Step-by-Step Guide for Manual Measurement:
If you prefer to measure your TV screen yourself or can’t find the details online, you can measure it manually. Here’s how to do it accurately:
Get a measuring tape or a ruler.
Make sure it’s long enough to span across the diagonal of the screen.
Measure the diagonal of the visible screen.
Place the measuring tape at one corner of the screen, either at the top-left or bottom-left corner, and extend it to the opposite corner (top-right or bottom-right). The measurement should be taken across the actual screen, not including the bezel (the frame around the screen).
Avoid the bezel.
The TV’s bezel should not be included in the measurement, as it does not count towards the size of the screen. Focus only on the visible area of the screen to get the correct size in inches.
Why Manual Measurement is Reliable:
Manual measurement is particularly useful when no other options are available or when you need to double-check the TV’s actual size. It’s also a helpful skill to have for measuring other screens, such as computer monitors or projectors.
Why the TV Box Information Can Be Useful:
If you still have the original packaging your TV came in, check the box for the screen size. Manufacturers often print essential details like:
TV screen size (in inches)
Model number
Key features and specifications
In some cases, the box may also include helpful information like the TV’s weight, which can be useful if you're considering mounting the TV or moving it.
While it might seem like an obvious step, many people forget to keep the original packaging. However, if you've kept it, this can be a handy resource. Not only does it tell you the TV size, but the box also provides protection if you ever need to transport or return the TV.
Advantages of Keeping the TV Box:
Protection during Transport: If you ever need to move the TV, the box offers extra protection.
Easier Returns/Exchanges: In case you need to exchange or return the TV, keeping the box can simplify the process.
Accurate Information: The box usually lists important details such as the screen size, model number, and resolution, which can help with choosing the right accessories or TV mounts.
Planning Your TV Placement:
Knowing the height, width, and depth of your TV helps you plan its placement more effectively. If you’re mounting your TV on a wall (using a Fixed TV mount, Tilt TV mount, or Full-motion TV mount), it’s essential to know how much space the TV will take up. Understanding these dimensions also helps when arranging your furniture around the TV, ensuring everything fits comfortably.
Difference Between TV Size and Actual Dimensions:
TV size usually refers to the diagonal measurement of the screen, but that’s not the full picture. The actual dimensions of your TV (height, width, and depth) include the frame around the screen (bezel) and can affect how it fits in your space. It's important to know both the size and the full dimensions to make sure the TV suits your room and mount.
Width Measurement:
To measure the width, use a tape measure to determine the horizontal length of the TV, from one side of the screen to the other. Be sure to measure across the visible screen area, excluding the bezel. This measurement is important when choosing a mount and when planning for the TV's placement in your room.
Height Measurement:
For the height, measure the vertical dimension from the top to the bottom of the screen. Again, focus only on the visible screen area, and do not include the bezel in this measurement. This is useful for ensuring the TV fits in your entertainment center or aligns well with the height of your seating area.
Depth Measurement:
Depth is the thickness of the TV, from the front to the back. Measure from the front of the screen to the back of the TV, including the bezel. Depth is especially important for wall mounting (it will affect the clearance between the TV and the wall) and for fitting the TV on a stand or TV cart (e.g., TV Cart Stand). Be aware that even though modern TVs are slim, the depth can vary depending on the model and additional features (like built-in speakers).
Aspect Ratio:
The aspect ratio refers to the proportion of the width and height of your TV screen. The most common ratio for modern TVs is 16:9, which provides a widescreen view. Older models might use the 4:3 ratio, which was common for CRT TVs. The aspect ratio affects how content appears on the screen. A 16:9 ratio is ideal for most movies and TV shows today, offering a more immersive viewing experience.
Resolution:
Resolution refers to the number of pixels on the screen. Higher resolution TVs, like 4K, provide sharper, more detailed images. This impacts the ideal viewing distance—4K TVs allow you to sit closer without noticing pixelation. If you have a Full HD (1080p) TV, sitting too close might make pixels visible, affecting the experience. For 4K, you can sit much closer, and the image will still look sharp, making the resolution an important factor in determining the best TV size and placement.
General Guidelines for Viewing Distance:
To get the best viewing experience, it's important to sit at the correct distance from your TV. A simple rule to follow is to multiply your TV size by 1.2. For example, if you have a 50-inch TV, the ideal distance would be around 60 inches (or about 5 feet) from the screen. This ensures you’re close enough for a clear, immersive view without straining your eyes.
Adjusting Viewing Distance for Different Resolutions:
For Full HD (1080p) TVs, you should sit a bit farther away compared to 4K TVs. Since 4K resolution has more pixels, it allows you to sit closer without noticing individual pixels. If you have a 4K TV, the ideal viewing distance is typically closer than that of a Full HD model. For example, with a 55-inch 4K TV, you can sit as close as 4 feet for a sharp, crisp image, while the same size in Full HD might require you to sit further away to maintain a high-quality viewing experience.
Key Measurements for Mounting:
Before you mount your TV, you’ll need to measure a few things. The most important are the height, width, and VESA mounting pattern.
Height and Width: Measure the TV’s full width and height (including the bezel). This ensures your mount can accommodate the TV’s overall size.
VESA Mounting Pattern: This refers to the distance between the mounting holes on the back of your TV. It’s important to check this measurement to ensure compatibility with the wall mount. The VESA pattern is usually listed in the TV's manual or on the manufacturer's website. Common patterns include 200x200mm, 400x400mm, etc.
Choosing the Right Mount for Your TV Size:
Once you have the measurements, selecting the right mount is easy. Here are a few tips:
Fixed TV Mount: Ideal for smaller TVs or when you want to keep the TV in one place. Ensure the mount supports your TV’s weight and VESA pattern.
Tilt TV Mount: Perfect if you want to adjust the angle slightly. This mount type works well for TVs that are mounted higher up.
Full-Motion TV Mount: Best for larger TVs and rooms with multiple seating areas. You can adjust the angle and pull the TV out from the wall.
Screen Size vs. Pixel Density:
Larger TVs can sometimes reduce pixel density, especially if the resolution stays the same. Pixel density refers to how many pixels are packed into each inch of the screen. With a larger screen, the pixels may be more spread out, which can affect image sharpness. For example, a 50-inch 1080p TV will have larger pixels than a 40-inch 1080p TV, leading to less sharp images, especially if you sit close to the screen.
Viewing Comfort:
Larger screens can lead to eye strain if you're sitting too close. The general recommendation is to maintain a viewing distance that prevents you from seeing individual pixels. For example, sitting too close to a big TV may result in discomfort as you try to take in the entire screen. Always adjust your seating distance according to your TV size and resolution.
Impact of Content on TV Size Decision:
What you watch plays a significant role in determining the best TV size. For example, watching movies or shows with rich visuals might be more immersive on a larger screen, while gaming could benefit from a smaller screen for faster action. Sports, on the other hand, might look best on a larger screen with a wide field of view. Consider your content preferences when selecting your TV size.
Adjusting TV Size Based on Content Type:
The size of your TV should align with what you're watching. For movies, a larger TV can enhance the cinematic experience, while a smaller screen might work better for casual TV shows or news. Gaming typically benefits from a more moderate-sized screen to avoid distractions and maintain a comfortable viewing distance. Always think about your primary use and adjust the TV size accordingly.
Measuring your TV screen accurately is crucial for proper mounting, comfort, and optimizing your space. Understanding TV dimensions ensures the right fit and viewing experience.
When choosing the best TV size, consider your room size, resolution, and personal preferences. This will help you select the perfect size and layout, ensuring the best setup for your viewing needs.
