Proportions absolutely matter for displays, both for aesthetic comfort and for efficient scaling. Most of the world uses ISO216 and its pleasing 1:sqrt(2) proportions. Leveraging aspect ratios with wide acceptance is a win both psychologically and for graphic designers.
- spappal 7d agoThe algebra proving why "halving long side H and flipping maintains aspect ratio" implies a ratio of 1:sqrt(2): H/W = W/(H/2) (halving long side H and flipping maintains aspect ratio) = 2W/H (multiply numerator and denominator by 2) H² = 2W² (multiply both sides by HW) H = √2·W ≈ 1.41 W (take the positive square root; H, W > 0)
