What Dual Monitor Size Fits My Desk?
Calculate dual-monitor fit using each monitor diagonal, aspect ratio width, and aspect ratio height.
Enter your measurements
To work out what dual monitor size fits my desk, begin with each monitor diagonal, aspect ratio width, and aspect ratio height. The calculator produces dual-monitor fit from the measurements that actually control the result.
- Each monitor diagonal — Required
- Aspect ratio width — Required
- Aspect ratio height — Required
- Gap between monitors — Required
- Desk edge margin each side — Required
- Desk width — Required
Dual-monitor fit
Enter the measurements above to calculate dual-monitor fit.
How the calculation works
V12 calculation: monitorWidth=monitorDiagonal×aspectWidth/sqrt(aspectWidth^2+aspectHeight^2); requiredDeskWidth=2×monitorWidth+centreGap+2×edgeMargin; fitPass=requiredDeskWidth≤deskWidth. This is the implementation specification for this calculator.
Worked example
Example: Each monitor diagonal = 27.2 cm; Aspect ratio width = 1; Aspect ratio height = 2; Gap between monitors = 11.44 cm; Desk edge margin each side = 14.54 cm; Desk width = 119.35 cm. Result: Fits; Required Desk Width = 64.86 cm; Monitor Width = 12.16 cm.
Before you decide
Enter the dimensions that will exist in real use, not an approximate catalogue category. This page calculates the stated geometry or quantity only; product-specific construction or installation details can still affect the final choice. For what dual monitor size fits my desk, the limiting result on this page is dual-monitor fit.
Direct measurement/geometry calculation. No external reference is required for the arithmetic itself; the result is derived only from the user-entered measurements and the formula stored in calculationLogicJson.
Frequently asked questions
What does the Dual Monitor Size calculator tell me?
It returns dual-monitor fit from the measurements entered on this page. The calculation is specific to dual monitor size, so the result should be compared with the exact product or specification you are considering.
Which measurements should I take for dual monitor size?
Measure each monitor diagonal, aspect ratio width, aspect ratio height, gap between monitors, desk edge margin each side, desk width. Use clear, usable dimensions rather than nominal room or product labels.
Should I round the dual-monitor fit?
Keep the calculated value for comparison, then choose a real product that meets or stays within the returned dual-monitor fit while allowing for the clearances, tolerances or ratings shown by its manufacturer.
