ステップバイステップガイド
- 11 point = 1/72 inch = 0.3528 mm
- 2Pixels depend on screen DPI: 1 pt ≈ 1.33 px at 96 DPI
- 372 DPI = traditional print, 96 DPI = screen standard
解いた例
入力
12pt font (typical)
結果
16px (screen), 4.23 mm (print)
DPI-dependent conversion
避けるべきよくある間違い
- ✕Assuming px-to-pt conversion without DPI context
- ✕Not accounting for browser DPI changes
