What to know
Screen sizes are diagonal measurements of the visible area. Width and height follow from the aspect ratio: for a ratio W:H, width = diagonal × W ÷ √(W² + H²).
On a desk, the stand footprint and depth matter as much as the width. Measure the depth of your desk and allow arm's length (about 20–30 in, 50–75 cm) between your eyes and the screen.
