Step 1 · Compare Screens to Scale

Pick two TV or monitor sizes. Stacking them from the same corner makes the true height and width gain immediately obvious.

Step 2 · Measure Suitcase Wheels Too

Measure your bag from floor to top handle including wheels. The green or red box shows if it slides inside metal gate sizers.

Step 3 · Leave 60 cm (24") Walkways

Enter your bedroom walls to verify whether doors open cleanly and at least 60 cm walking space remains on both sides.
