TV Screen Size Calculator
Aspect Ratio Calculator
Viewing Distance Calculator
TV Price Per Inch Calculator
Buying a new TV can be exciting—but also confusing. One of the most common questions is:
“What TV size is best for my room?”
Choosing the wrong size can result in eye strain, poor viewing experience, and wasted money. Sit too close to a big TV, and you’ll see pixels. Sit too far from a small screen, and you’ll miss details.
That’s why the TV Calculator exists.
This easy-to-use online tool helps you find the ideal TV size based on your viewing distance and calculate the best viewing distance for your TV size and resolution. It ensures you get a comfortable, immersive viewing experience without guessing or complicated math.
📺 What Is the TV Calculator?
The TV Calculator is a free web-based tool designed to calculate optimal TV screen size and seating distance for the best viewing experience.
It uses recommendations from trusted sources like THX and the Society of Motion Picture and Television Engineers (SMPTE) to suggest:
- The best TV size based on how far you sit from the screen
- The ideal viewing distance based on your TV’s size and resolution (HD, 4K, 8K)
- Optional calculations for field of view (FOV) for cinematic setups
This calculator removes the guesswork and helps you make an informed buying decision before spending money on a new television.
⚙️ How to Use the TV Calculator (Step-by-Step)

💡 Practical Examples
Here are two real-life examples to understand how the TV Calculator works:
📏 Example 1: You Know the Distance (Find TV Size)
- Viewing distance: 8 feet
- Resolution: 4K
Formula guideline (THX):
Recommended screen size = Viewing distance (in inches) × 0.84
8 feet = 96 inches
96 × 0.84 ≈ 80.64 inches
Result: The ideal TV size is around 80 inches (75″–85″ range).
📏 Example 2: You Know the TV Size (Find Distance)
- TV size: 65 inches
- Resolution: 4K
Formula guideline (SMPTE):
Recommended viewing distance ≈ TV size × 1.5
65 × 1.5 = 97.5 inches
≈ 8.1 feet
Result: The ideal viewing distance is about 8 feet from a 65-inch 4K TV.
