Step 02

Choose one display plan.

Design for the screen system you will actually use, not every possible future upgrade.

Step 03

Complete the reality check.

The calculator covers footprint. These seven checks catch the physical details that dimensions miss.

01Desk wallMeasure the clear wall width. Subtract door swing, trim, radiators and anything that cannot move.02Desk depthUse at least 28 inches for a large monitor. Add more if the display cannot move on an arm.03Chair clearanceReserve at least 36 inches behind the desk edge so the chair can roll back and you can stand.04SightlineYour eye level should land near the upper third of the screen, roughly 24–32 inches away.05Power + dataChoose one under-desk power rail and one route to the outlet. Do not daisy-chain power strips.06Heat + airLeave intake and exhaust space around the PC. Do not hide it in a closed cabinet for the photo.07LightingLayer room light, task light and one accent. If everything glows, nothing is a focal point.
