How to Use the TV Mounting Height Calculator
What is a TV Mounting Height Calculator?
A TV mounting height calculator helps you determine the optimal height to mount your television for the best viewing experience. This tool considers factors like screen size, 視聴距離, and eye level to provide accurate mounting recommendations.
Why Proper TV Height Matters
Mounting your TV at the correct height ensures:
- Comfortable viewing without neck strain
- Optimal viewing angles for better picture quality
- Reduced eye fatigue during extended viewing sessions
- Professional-looking installation in your home
Getting Started
ステップ 1: Choose Your Calculation Mode
The calculator offers two modes:
Calculate Mounting Height – Use this when you know your desired viewing angle and want to find the ideal mounting height.
Calculate Viewing Angle – Use this when you already know where you want to mount the TV and need to check the viewing angle.
ステップ 2: Select Your Measurement Unit
Choose between:
- Inches (で) – Standard in the US
- Centimeters (cm) – Metric system
Note: TV screen sizes are always measured in inches (industry standard), but you can use either unit for other measurements.
Mode 1: Calculate Mounting Height
Required Information
-
TV Screen Size (diagonal in inches)
- Example: 55″, 65″, 75″
- This is the diagonal measurement of your TV screen
-
Seated Eye Height
- Measure from the floor to your eye level while seated
- Typical range: 38-42 インチ (97-107 cm)
-
視野角 (in degrees)
- Recommended: 0° to 15°
- 0° = TV center at eye level (ideal)
- 10-15° = TV slightly above eye level
-
Viewing Distance (optional)
- Distance from your seating position to the TV
- Leave blank for automatic calculation
How to Calculate
- Enter your TV screen size
- Select your preferred measurement unit
- Enter your seated eye height
- Set your desired viewing angle (0° recommended)
- Click “Calculate Mounting Height”
Understanding Your Results
The calculator provides:
- Screen Center Height – Where to position the TV’s center
- Screen Bottom Height – Where the bottom edge should be
- Screen Height – Total height of your TV screen
- Viewing Distance – Optimal distance from TV
- 視野角 – Angle from eye level to screen center
- Field of View (FOV) – How much of your vision the TV fills
Mode 2: Calculate Viewing Angle
Required Information
- TV Screen Size (diagonal in inches)
- Seated Eye Height
- Measure TV Height From
- Center of Screen (Recommended)
- Bottom of Screen
- TV Mounting Height
- Current or planned mounting position
- Viewing Distance
- Distance from seating to TV
How to Calculate
- Switch to “Calculate Viewing Angle” tab
- Enter your TV screen size
- Select measurement unit
- Enter seated eye height
- Choose measurement reference point (center or bottom)
- Enter TV mounting height
- Enter viewing distance
- Click “Calculate Viewing Angle”
Expert Recommendations
Ideal Viewing Angle
- 0° to 15° is optimal
- Eye level or slightly above reduces neck strain
- Avoid mounting too high (common mistake)
Optimal Field of View (FOV)
- 30° to 40° for immersive viewing
- Larger screens need greater viewing distance
- 4K TVs can be viewed closer than 1080p
General Guidelines
- Living Room: Mount TV center at seated eye level (typically 42″)
- Bedroom: Slightly higher is acceptable (up to 15° angle)
- Home Theater: Exactly at eye level for best experience
Common TV Sizes and Recommended Distances
| テレビのサイズ | Optimal Viewing Distance |
|---|---|
| 43″ | 5.4 – 6.9 feet (165-210 cm) |
| 50″ | 6.3 – 8.0 feet (190-245 cm) |
| 55″ | 6.9 – 8.8 feet (210-270 cm) |
| 65″ | 8.1 – 10.4 feet (250-315 cm) |
| 75″ | 9.4 – 12.0 feet (285-365 cm) |
よくある質問
How high should I mount my TV?
For most living rooms, mount the TV so the center is at seated eye level (通常 40-42 床からインチ). This creates a 0° viewing angle, which is ideal for comfort.
What if my TV is above a fireplace?
TVs above fireplaces are often mounted too high. If unavoidable, use a tilting mount to angle the screen downward and minimize neck strain.
Does screen size affect mounting height?
はい! Larger screens have greater height, so the mounting point (center) may need adjustment to keep the screen properly positioned relative to your eye level.
Can I use this calculator for bedroom TVs?
絶対に! For bedrooms, you may prefer a slightly higher mounting position (5-15° angle) since you might watch from a reclined position.
What’s the difference between center and bottom mounting measurements?
- Center: Measures to the middle of the screen (most common)
- Bottom: Measures to the bottom edge of the screen (useful if you have existing measurements)
Tips for Best Results
- Measure accurately – Use a tape measure for precise measurements
- Consider furniture – Account for the height of your TV stand or console
- Test before drilling – Have someone hold the TV at the calculated height
- Use a level – Ensure your mount is perfectly horizontal
- Check viewing from all seats – Verify comfort from different positions
