Depends on size of room and how far you are sitting from the tv to view it.
“To determine the right TV size, measure the distance between your seating position and the potential TV location. For Full HD TVs, aim for a viewing distance of 1.5 to 2.5 times the screen size. For 4K TVs, a viewing distance of approximately the same as the screen size is recommended. Consider the room's size and if you're planning on using the TV for movies or gaming, which may influence your preferred viewing distance.
Here's a more detailed breakdown:
- 1. Measure the Viewing Distance:
Use a tape measure to determine the distance from your seating position to the wall where the TV will be placed.
- 2. Consider TV Type and Resolution:
4K TVs generally require closer viewing distances compared to Full HD TVs.
- 3. Calculate Recommended Screen Size:
- Full HD: Divide the viewing distance by 1.5 or 2.5 to get the recommended screen size.
- 4K: Aim for a viewing distance that is approximately the same as the screen size.
- 4. Factor in Field of View:
The Society of Motion Picture and Television Engineers (SMPTE) recommends filling 30 degrees of your field of vision with the TV. This means the screen should appear to stretch approximately from your left eye to your right eye.
- 5. Consider Room Size and Use:
- Smaller Rooms: For bedrooms or kitchens, smaller TVs (under 50 inches) might be ideal.
- Larger Rooms: Living rooms can accommodate larger TVs, with 50 to 65 inches being a common range.
- Home Cinema: For a truly immersive experience, screens of 70 inches or larger are a great choice.
- 6. Experiment with Tape:
You can use painter's tape to outline different TV sizes on the wall to get a visual representation of how they'll look.
Example:
If you're sitting 8 feet (96 inches) from the TV and you have a Full HD TV, you could divide 96 by 2.5 to get a recommended screen size of around 38.4 inches. A 40-inch TV might be a good fit.
Additional Tips:
Don't be afraid to go slightly larger: If you prefer a more immersive experience, you can go slightly larger than the recommended screen size.
Consider your budget: TV prices vary widely depending on size and features.
Read reviews: Check reviews from reputable sources to get insights into different TV models.”
There are a lot of reasons to go greater than 40”. Some rooms you would see nothing with a 40”, unless you were using binoculars.
