Monitor planning tool

Monitor Size Calculator: Desk Fit, Resolution, and Viewing Distance

Match monitor diagonal, resolution class, and desk footprint before you chase refresh-rate marketing. Measure your desk depth and eye-to-screen distance first.

This tool is a planning estimate, not a product rating, price quote, medical/legal/safety certification, or retailer availability check. Based on your inputs only—no live price, stock, or availability verification.

How this estimate works

Desk depth limits how close you can sit; viewing distance steers whether 27″, 32″, or ultrawide makes sense. Dual-monitor setups need width headroom. The result pairs size class with resolution guidance—1440p and 4K trade sharpness for GPU load, especially in gaming.

Your inputs

Enter a few details and this tool will give you a planning estimate. It does not verify live price, stock, or product availability.

Common mistakes

  • Buying 4K for gaming without checking GPU headroom
  • Ignoring desk depth with deep stands or monitor arms
