Dual-Monitor Desk Width Calculator
Estimate required desk width from actual monitor widths, desired gap and side clearance.
Planning aid only. Use exact manufacturer dimensional limits for the desk, frame, chair or monitor hardware you actually buy.
Measure actual chassis width, not diagonal screen size.
What this tool does not decide
A calculator cannot predict build quality, long-term durability or stability from a few numbers. Use it to eliminate incompatible configurations, then compare exact-model documentation.
