TV Width Calculator
Choosing the right TV size and understanding its actual dimensions can be confusing. Most TVs are advertised by diagonal screen size (inches), but what about the actual width and height? Knowing these measurements is crucial for fitting your TV into your living space or entertainment center.
Our TV Width Calculator lets you quickly calculate the screen width, height, total size with bezel, and even recommends an optimal viewing distance based on your TV’s diagonal size and aspect ratio. It supports common aspect ratios like 16:9, 21:9, 4:3, and more, plus lets you choose units in inches, centimeters, or feet.
Why Calculate TV Width and Height?
- Space Planning: Ensure your TV fits perfectly in your designated spot.
- Mounting: Know the exact dimensions for wall mounts or furniture compatibility.
- Viewing Comfort: Determine the best distance for comfortable viewing.
- Bezel Consideration: Account for the frame thickness to avoid surprises.

How It Works: The Math Behind the Calculator
The TV screen width and height relate to the diagonal size by the aspect ratio using Pythagoras theorem:
- Aspect Ratio factor = width ratio ÷ height ratio
- Screen width = diagonal ÷ √(1 + (1/aspectRatioFactor²))
- Screen height = screen width ÷ aspectRatioFactor
Adding bezel size on both sides gives total width and height.
Recommended viewing distance is approximately 1.5 times the screen width for comfortable viewing.
Example
- Diagonal Size: 55 inches
- Aspect Ratio: 16:9 (Standard HDTV)
- Bezel Size: 0.5 inch per side
- Unit: Inches
Calculations:
- Screen width ≈ 47.94 inches
- Screen height ≈ 26.96 inches
- Total width with bezel ≈ 48.94 inches
- Total height with bezel ≈ 27.96 inches
- Viewing distance ≈ 71.91 inches (about 6 feet)
Perfect for planning your room setup!
Frequently Asked Questions (FAQs)
1. What is aspect ratio?
Aspect ratio is the ratio of width to height of the screen.
2. Why is the diagonal size different from width and height?
Diagonal size measures corner-to-corner distance, not width or height.
3. How does bezel size affect total TV size?
Bezel adds to the width and height, making the overall footprint larger.
4. Can I measure bezel size myself?
Yes, measure the frame thickness on one side of your TV.
5. Why choose different measurement units?
Choose units that suit your room or mounting measurements.
6. What is the best viewing distance for my TV?
Recommended viewing distance is about 1.5 times the screen width.
7. Does the calculator work for computer monitors?
Yes, just select the correct aspect ratio (e.g., 16:10).
8. What if I don’t know my TV’s bezel size?
Use the default 0.5 inch or check the TV specs online.
9. Can I use the calculator for projector screens?
Yes, it works for any screen size and aspect ratio.
10. What does the 21:9 aspect ratio mean?
It’s an ultrawide screen often used for cinematic viewing.
