| Usage notes | Use 'dimension' when discussing physical sizes or aspects of things. It's appropriate in technical and academic contexts but can be less common in casual conversation. | Use 'extent' in formal or written contexts when discussing levels or degrees. It's less common in everyday speech. | Use 'measurement' in technical settings, like science or construction. It may sound too formal in casual conversations about everyday things. | Used in both formal and informal contexts. 'Size' is suitable for descriptions of objects, clothing, and measurements but is less appropriate for abstract concepts without clear dimensions. |
