Mathematical Formulas & Step-by-Step Derivation▼
Screen dimensions are calculated using the Pythagorean Theorem (W² + H² = D²) combined with the ratio proportion W / H = Rw / Rh:
1. Screen Width from Diagonal (d) and Ratio (w:h):
Width = d × w ÷ √(w² + h²)2. Screen Height from Diagonal (d) and Ratio (w:h):
Height = d × h ÷ √(w² + h²)3. Screen Area:
Area = Width × Height4. Pixel Density (PPI):
PPI = √(Horiz_px² + Vert_px²) ÷ Diagonal_inOptimal Viewing Distance: SMPTE recommends a 30-degree field of view for mixed multimedia (Distance ≈ Diagonal × 1.62), while THX recommends a 40-degree field of view for cinematic immersion (Distance ≈ Diagonal × 1.2).
FAQ
Come si calcolano le proporzioni dello schermo?
Dividi la risoluzione orizzontale per quella verticale e riduci entrambi i numeri per il massimo comune divisore (es. 1920×1080 diventa 16:9).
Il mio schermo è 16:9 o 16:10?
Controlla la risoluzione nelle impostazioni. Un rapporto di circa 1,78 indica 16:9; un rapporto di 1,6 indica 16:10.
