Are you in the market for a new TV but feeling overwhelmed by all the size options available? Don't worry; we've got you covered! In this guide, we'll break down everything you need to know about TV sizes, viewing distance, and how to make the right decision that perfectly suits your space and viewing needs.
How To Measure TV Size
If you're unsure of the exact TV size you are looking at, or want to know what your own TV size is, thankfully measuring tv size is quite simple!
First off, a TVs "size" is simply the diagonal length measured from the top left hand corner of the TV screen to the bottom right hand corner (just the screen - don't include the frame). So if you have a measuring tape, run it along that diagonal length across the screen (top left to bottom right), then you want to take note of the measurement in inches. This is the TV Size (since they are all advertised in inches) and how to measure a TV screen.
So now when you are shopping for a new TV and you see one that's advertised as a "brand new 65 inch TV", you know this means that from the top left hand corner down to the bottom right hand corner of that tv screen, it would measure 65 inches.

What's the ideal TV size for my room?
How do I calculate the viewing distance for different TV sizes?
While there's no one-size-fits-all answer, to calculate the ideal viewing distance, the simplest formula is to multiply the screen size of the TV by 3 and this what your viewing distance should be (in cm). This calculation ensures that the TV takes up around 40 degrees of your field of vision, creating an immersive cinema-like experience in your home.
For example, for a 75-inch TV, the best viewing distance would be 225cm or about 7 feet. Still unsure? Don't worry. We've broken down all the common TV Sizes and the recommended viewing distance for you below.
Screen Size (inch) | Recommended Viewing Distance (cm) | Recommended Viewing Distance (feet) |
|---|---|---|
72cm | 2 feet | |
96cm | 3 feet | |
120cm | 4 feet | |
129cm | 4 feet | |
49 inch | 147cm | 5 feet |
165cm | 5 feet | |
60 inch | 180cm | 6 feet |
195cm | 6 feet | |

How to measure for a new TV - Step by Step Guide
What you'll need :
- Tape Measure
- Pencil & Paper
- Stud Finder (Optional)
- Level (Optional)
- Step Ladder (Optional)
- Helper (Optional)
1. Measure wall/furniture space.
Measure the available wall space or furniture width, height and depth dimensions. Confirm the TV's dimensions will fit the designated area - make sure you know the dimensions of the TV stand if the TV is going to stand on it's own.
2. Identify the main viewing position and measure the viewing distance.
Find the main viewing spot where you're going to be watching from and measure the distance from the seating position to where the TV will be mounted/placed. This is your viewing distance.
3. Calculate the recommended TV size range based on viewing distance.
Use the viewing distance to determine the ideal screen size range. We've made it easy for you, just check our viewing distance table guide at the top of this page and cross check with the distance you have available.
4. Measure the height of the viewing area for optimal TV placement.
Ensure the TV will be at an optimal eye-level position when seated. Measure the height of the viewing area from the floor.
5. Check the TV's weight and ensure the mount/furniture can support it.
Verify the mount or furniture can safely support the TV's weight. Refer to the manufacturer's specifications for the TV's weight and the mount/furniture's weight capacity. We also have a general tv weight guide which provides the common weight ranges of tvs based off of their sizes.
6. If wall-mounting, measure stud locations for proper support.
Identify secure wall stud positions if wall-mounting the TV. Use a stud finder to locate and mark the stud positions.
7. Assess room lighting conditions for potential glare/reflection.
Consider the room's brightness levels for potential glare or reflection. Observe the lighting conditions at different times of the day.
8. Plan for cable management and access to power outlets.
Accommodate for cable management and access to power outlets. Measure the distances to nearby outlets and plan for cable routing.
