What measurement refers to the distance from the collar edge on the back to the hem of the garment?

The measurement that refers to the distance from the collar edge on the back to the hem of the garment is called back length. This measurement provides an important indication of the overall length of the garment from the highest point of the back, which is typically where the collar sits, down to the bottom hem. Understanding back length is crucial in determining how a garment will fit on a person's body, especially in ensuring that tops like shirts, blouses, or coats provide the right coverage and comfort.

Body length, although it might sound similar, usually refers to a general measurement on the body rather than being specifically about the distance from the collar to the hem. Sleeve width relates to how wide the sleeves of the garment are and does not pertain to the measurement of the garment length itself. Chest width typically measures the garment across the front at the chest level, which does not include the back length measurement. Thus, back length is the precise term that accurately describes the measurement in question.
