XTEN-AV has long been a leader in providing innovative AV solutions for both professional and personal environments. One trend that continues to grow in popularity is the use of dual display setups. Whether for corporate offices, control rooms, classrooms, or home workspaces, dual screens offer increased productivity, better multitasking, and an immersive viewing experience.
However, choosing the right screen sizes for a dual display setup requires thoughtful planning. The wrong screen size can cause discomfort, reduce productivity, or even create an unbalanced aesthetic. That’s where a screen size calculator comes into play. In this blog, we’ll explore how to calculate and choose the ideal screen sizes for dual display configurations to maximize comfort and efficiency.
Why Dual Display Setups Are Popular
Dual monitors have become a standard in many work and creative environments. They allow users to:
- Run multiple applications simultaneously
- Compare documents side-by-side
- Monitor data streams while working on tasks
- Enhance collaboration in meetings and presentations
For these reasons, it’s essential to select screen sizes that suit the workspace and intended tasks without causing eye strain or neck discomfort.
Key Factors to Consider When Calculating Screen Size
1. Viewing Distance and Workspace Dimensions
Just like with single displays, viewing distance is crucial. For dual setups, consider the distance from your eyes to the screens, as well as the space between the two monitors. A typical comfortable viewing distance ranges from 20 to 30 inches.
Measure your desk width and available space carefully. If your workspace is limited, larger monitors may not fit comfortably side by side.
2. Screen Height and Alignment
When placing two screens side by side, their heights should be aligned to prevent awkward head movements. Calculating the ideal screen height based on your eye level and seating posture is essential for comfort.
Using a Screen Size Calculator for Dual Displays
A screen size calculator helps you find the right dimensions by considering factors like viewing distance, screen resolution, and content type. Here’s how to use it effectively for dual display setups:
- Input your typical viewing distance from your seated position to the monitors.
- Consider the aspect ratio (commonly 16:9 for most monitors).
- Specify if you’ll be using the displays for text-heavy work, video editing, gaming, or general office tasks.
- The calculator will suggest an ideal diagonal size for each monitor.
How to Calculate Total Screen Width and Height
If you have two identical monitors, calculating the combined width is straightforward:

Total Width = Width of one screen × 2
To find the width of one screen when you have the diagonal size and aspect ratio:
- Use the aspect ratio formula (16:9):
ini

Width = Diagonal × (16 / √(16² + 9²))
- Calculate height similarly:
ini

Height = Diagonal × (9 / √(16² + 9²))
For example, if you choose 27-inch monitors:
- Width ≈ 27 × 0.8716 = 23.53 inches
- Height ≈ 27 × 0.4903 = 13.24 inches
So total width side by side is about 47.06 inches.
Consider Viewing Angles and Ergonomics
Dual displays create a wider field of view, so it’s important to angle the screens properly. Each should be tilted slightly inward toward the user to maintain consistent viewing distances and reduce eye and neck strain.
The top of the monitors should be at or slightly below eye level to promote good posture.
Example Scenario: Office Dual Monitor Setup
Imagine a user with a 28-inch viewing distance and a desk that fits monitors up to 30 inches wide. Using a screen size calculator, the recommendation might be 24 to 27-inch monitors for comfortable viewing and space optimization.
With two 27-inch monitors side by side, the total width of roughly 47 inches fits well on the desk, with room for keyboard and other accessories. The user angles the monitors slightly and aligns their height for ergonomic comfort.
Matching Resolution and Screen Size
In dual setups, matching screen resolution and size is crucial. Mismatched sizes or resolutions can cause discomfort and disrupt workflow. Using screens with the same resolution ensures consistent image quality and scaling across displays.
For detailed work, a higher resolution paired with an appropriate screen size allows better clarity and more workspace on each screen.
Final Tips for Dual Display Screen Size Calculation
- Measure your workspace and seating position accurately.
- Use a screen size calculator to get a recommended diagonal size based on your viewing distance.
- Choose monitors with matching aspect ratios and resolutions for uniformity.
- Pay attention to ergonomics—height, tilt, and distance are key to comfort.
- Consider desk accessories like monitor arms to optimize placement flexibility.
Conclusion
Dual display setups can greatly improve productivity and user experience, but selecting the right screen sizes is essential to avoid discomfort and maximize efficiency. A screen size calculator is a valuable tool in this process, providing data-driven recommendations tailored to your workspace and tasks.
