## Definition

public readonly float sqrMagnitude { get; }
```

### Remarks

Calculating the squared magnitude instead of the [Vector2.magnitude](/engine/6000.6/script-reference/unityengine/vector2/magnitude.md) is much faster. Often if you are comparing magnitudes of two vectors you can just compare their squared magnitudes.
