プロの活用テクニック&推奨設定

21:9 Ultrawide & Cinema 2.370:1

Popularized by panoramic gaming monitors (3440×1440 UWQHD, 2560×1080 UWFHD) and anamorphic theatrical cinematography. Technically defined in consumer monitors as 64:27 (~2.370:1).

Mathematical Formulas & Macroblock Rules

1. Calculating Proportional Dimension:

Height = Width / (Ratio_W / Ratio_H)

Width = Height × (Ratio_W / Ratio_H)

よくあるトラブルと解決策

Unexpected output or validation warning in 16:9, 4:3, 21:9 Resolution Scaler & Canvas Calculator

Verify that your custom ratio w matches the expected string format. Load a built-in sample preset to compare structural formatting.

Exported aspect ratio calculator result differs across target environments

Check the custom ratio h setting in 16:9, 4:3, 21:9 Resolution Scaler & Canvas Calculator to ensure encoding, precision, or specification version matches your target runtime.
