For sleeve measurement, what is measured from the center back collar to the bottom edge of the sleeve hem?

The sleeve measurement from the center back collar to the bottom edge of the sleeve hem is termed sleeve length. This measurement is crucial in garment construction and fitting, as it determines how long the sleeves will be on a garment. Accurate sleeve length ensures that the sleeves fit comfortably and appropriately on the wearer's arms, allowing for ease of movement while also maintaining the desired style of the clothing.

Other measurements listed do not pertain to the same aspect of garment measurement. For instance, shoulder width relates to the measurement across the shoulders, neck circumference pertains to the measurement around the neck, and back length measures from a specific point on the back down to a designated length. Each of these serves different purposes in tailoring and fitting garments, but only sleeve length specifically describes the measurement in question.
