How to Measure Your TV Screen Size

If you’re like many shoppers, you’ve probably wondered how to measure your TV screen size. You’re not alone in this confusion, as it can be a difficult and daunting task.

That’s why we’re here to help! You can rest assured that after going through this article, you’ll have the know-how to accurately measure your TV screen size quickly and easily!

Measuring the size of your TV can be an important factor when considering purchasing a television, especially with all the varying sizes and dimensions on the market. It is also important to measure if you are planning to mount your TV on the wall or fit it into a new cabinet.

In this guide, we will teach you how to properly measure your TV screen so that you can find exactly what you need and make a smart, informed purchase.

Importance of knowing TV screen size

Knowing your TV screen size is important for many reasons. The most important being that it helps you choose a TV wall mount to fit your TV. Selecting the right size of wall mount is essential as it determines how far away from the wall your TV hangs and how stable it will be when mounted. This also affects its cords and cables, as some of them may be visible or hidden by the size of wall mount you choose.

Another reason it’s important to determine your TV screen size beforehand is to ensure you don’t buy an undersized or oversized TV stand or cabinet for your needs. If your chosen stand doesn’t fit the actual measurements of your television, then not only will it look out of place in your room, but it will also be unsteady when needed to support a larger device than planned. It may either need further support or replacement with a larger model. Knowing the exact measurements in advance can save you both time and money in combination with determining exactly what tv stand best fits into both budget and lifestyle desires.

Brief explanation of how to measure TV screen size

Measuring the size of your TV can help you select the proper viewing distance, mount or stand size, and to determine mount or stand weight capacity. Here’s a brief explanation of how to measure your TV’s screen size in inches.

First, you’ll need a measuring tape or ruler. If using a tape measure, hold it diagonally from corner to opposite corner and record the measurement in inches. If using a ruler, place the end of it at one corner and extend it across the TV’s face until it reaches the opposite corner; then note the number of inches that appear on the ruler.

In some cases, TV sizes are classified by other measurements such as diagonal centimeters (cm). In these instances divide your measurement by 2.54 (or simply multiply by 0.39) to obtain its equivalent dimension in inches.

You should now have an accurate measurement for your TV’s screen size – which is often useful for selecting potential mounting solutions as well as determining viewing distances for optimal picture quality.

Measuring TV Screen Size

In order to measure your TV’s screen size, you will need a measuring tape, a pen and paper to record the measurements, and preferably someone else to help.

Start by standing in front of the TV and finding the top two corners on each side with the longest diagonal distance. Measure this distance between these two points- this is your TV’s diagonal screen size.

To get more specific measurements, if you are able to move around your TV or take off/open the back panel of your TV, try measuring the height and width of your screen in both inches and centimeters. Make sure to record these details in case you need them later when shopping for accessories like wall mounts or external speakers catered specifically for your model of television.

Measuring diagonally

  1. Measuring diagonally: To accurately measure your TV screen size, use a tape measure or ruler to determine the full diagonal width of your screen. Measure from the bottom left corner to the top right corner and writing down the number of inches. This is your TV’s diagonal screen size measurement and will be used to determine which size TVs are compatible with your space. Be sure to factor in any space that may be taken up by the bezel (the frame around the display).
  2. Measuring Horizontally & Vertically: Another reliable way to measure for a new television is by taking horizontal and vertical measurements of your existing television for reference when shopping for a new one. To accurately get these measurements, you will need both a steel or cloth measuring tape as well as a pencil or pen for marking down measurements.

Start by measuring from one side of the current TV’s display all the way across until you reach the opposite side in both horizontal and vertical directions. Make sure to measure with precision and record each number separately – this ensures that you get an accurate representation of how much space will be available when shopping for your new television set.

Materials needed

Before you start measuring the size of your television, it is important to gather the right materials. These include a measuring tape, a straight edge (ruler or yardstick), some clear tape and a cloth or soft surface to work on. Make sure all the materials are clean before you begin.

Once you have your materials ready, it is time to start measuring. Place your TV screen gently onto the soft surface and secure it with clear tape if needed. This will help keep it in place while you measure and prevent accidental damage to the TV screen itself. Follow these easy steps:

1) Using your ruler or yardstick, measure the width of your television screen across the widest point from left to right in inches.

2) Measure the height at the highest point from top to bottom in inches as well.

3) Write down both measurements, then add them together for an approximate total size of your television screen in square inches.

Steps to follow

Step 2: Measure the actual size of your TV screen—not including any external frame or casing around it. This can be done using a simple measuring tape. To do this, start by measuring the width of the screen from the left side to right side in inches. Then measure the height of the screen from top to bottom in inches.

Remember to measure only the main viewing area and ignore any outer frame when taking measurements. The numbers you get are your TV’s exact width and height in inches.

 Tips for Accurate Measurements

When measuring your television screen size, it is important to be as accurate as possible. It is best to use an ordinary ruler that’s at least 12 inches long or a metal tape measure. To make sure your measurements are as accurate as possible, here are a few tips you can follow:

-Take the measurements of the diagonal length of the screen instead of any individual side since this will give you the most accurate reading.

-Mark off any bezels and indicate the numbered measurement for where to begin and end your measurement with a pencil line or small tag.

-Be sure that both ends of the ruler or metal measuring tape are flush with each other when taking your readings, as this will help ensure accuracy in your measurements.

-Orient your ruler/measuring tape along a straight line which corresponds with the starting and ending points of your measurement—this helps ensure precision in readability and allows for easier numbers interpretation.

-If using a ruler, hold it tight against each side while taking fresh readings on each measurement you take—this will help remove any discrepancies between numbers when taking multiple readings adjacent to one another.

-Once you have taken all necessary measurements, add them up together to get an overall sum which is the most accurate reflection of your television’s actual size.

Avoiding obstructions

When measuring the screen size of a TV set, it is important to make sure that there are no obstructions in the way of your view. Make sure that all furniture, stands, and any wall trimming or surrounding materials are out of the way. Position yourself in front of the television at an optimal viewing distance with a straight perpendicular sightline. Avoid having items like lamps obstructing your view and ensure that the lighting is not coming from one side excessively.

Place a soft cloth or blanket on top of any furniture that may not stay steady when attempting to hold a measuring tape. The surface should be flat and smooth before taking measurements.

Measuring from corner to corner

To measure your TV screen size correctly, it’s best to use a measuring tape and measure from corner to corner in a straight line across the face of the TV. It’s important to measure diagonally from opposite corners for the most accurate measurement of your TV’s size. This method should work for the majority of flat-panel TVs.

Once you have taken this measurement, look on the label attached to the back or side of your television set or in its instruction manual for information about what its actual screen size is.


Once you have taken the measurements of your TV, you can now confidently choose a new one with the right size to fit your space. Be sure to check the specifications of any new TV before you buy it so that you know it will fit into the space where your old set was.

Another important factor to consider when selecting the right size of TV is how far away you will be sitting from the screen. If sitting close, a smaller screen size might be better as images on larger screens may appear less clear up close.

Finally, pay attention to what type and resolution your new TV offers. A higher resolution may make a difference in image quality for larger screens compared to smaller ones.

Now that you know how to measure your current TV and have some helpful tips for choosing a new one, start shopping around for your ideal viewing setup today!

Recap of importance of knowing TV screen size

Knowing the measurements of your television screen size is an essential step in making sure you choose the right sized television that not only fits the space you have but also suits your viewing needs. If a TV isn’t the right size for your room, it could end up being uncomfortable to watch. On too large, then you’re craning to see every corner – on too small and you can’t appreciate some of the rich details that come from higher resolution shows and movies. Whether your TV is rectangular, square-shaped or significantly curved, it is important to take note of its overall size in order to properly plan for mounting or other installations.

To recap, here are some important considerations when checking the size of your television:

  • Check both width and height measurements
  • Compare to existing furniture/spaces
  • Check maximum weight capacity before installation
  • Take into account aspect ratio (shape)
  • Consider visual distance
  • Make sure cords/connections reach if they need to

Recap of how to measure TV screen size accurately

Before you buy a new TV or purchase a TV mount, it’s important to know how to measure your television screen size accurately. To ensure you get the right size mount or stand, here are some steps to follow:

-Measure the length and width of the visible area of the display. Measure only the length and width of the actual viewing area, not including any areas that are recessed behind bezels or outer casing.

-Once you’ve noted those measurements, multiply them to get the total diagonal measurement of your display in inches. Your result will be a two-digit number (for example, from 25″ x 14″ = 350″).

-To make sure your purchase is correct, round this number up and use that as your screen size. In our example above, you’d need a TV mount for at least a 35″ display.

By properly measuring your television screen size using these steps, you can accurately determine which TV mount or stand is best suited for your TV set up.
