Aspect Ratio Calculator - Wann Nutzen

Last reviewed: 2026-07-24

Es lohnt sich, den Aspect Ratio Calculator zu öffnen, wann immer du ein Foto, einen Videoframe oder eine Design-Fläche ohne Verzerrung skalieren musst. Diese Seite erklärt, wann das passt und wann nicht.

Wann es passt

Nutze ihn vor der Skalierung eines Bildes oder Video-Exports, bei der Wahl eines Ausschnitts, der zu einer Zielplattform passt (etwa 16:9 für Breitbild-Video oder 9:16 für vertikales Mobil-Video), oder wenn du einfach wissen willst, auf welches Verhältnis eine gegebene Breite und Höhe sich reduzieren.

Was zu erwarten ist

Die Berechnung läuft lokal im Browser - kein Upload und kein Konto. Sie berechnet nur die Zahlen; sie öffnet, schneidet, skaliert oder exportiert keine tatsächliche Bild- oder Videodatei.
