How to get width at which Inspector does line breaks (for Vectors)

Question

I am writing a property drawer which draws Vector4s as single lines in arrays using EditorGUI.Vector4Field(). I would like to keep the functionality of having it expand to two lines when the inspector is narrow.

something along these lines works

 EditorGUIUtility.currentViewWidth < 345 ? baseHeight * 2 : baseHeight;

but how do I get the correct value instead of the magic number 345?

You will have to make a CustomPropertyDrawer

I am writing a property drawer

... I have done that. The question is about how to achieve the line break in this custom property drawer without comparing with this magic number.

 [CustomPropertyDrawer(typeof(VectorInlineAttribute))]
 public class VectorInlinePropertyDrawer : PropertyDrawer
 {
 
   ...
 
     public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
     {
         float baseHeight = base.GetPropertyHeight(property, label);
         if (property.propertyPath.Contains(".Array.")) { return baseHeight; }
         else
         {
             return EditorGUIUtility.currentViewWidth < 345 ? baseHeight * 2 : baseHeight;
         }
     }
 }
