Measurements of size, weight & proportions are called...

Orthostatic refers to a condition related to an upright position or the body's response to changes in posture, particularly concerning blood pressure. This term does not encompass measurements of size, weight, or proportions, making it irrelevant in the context of anthropometric data.

Fundal measurements are related to the measurement of the fundus, or the upper part of the uterus, primarily during pregnancy. While this term may involve size measurements, it is specific to a medical context and does not address overall human body measurements, thus making it an incorrect choice.

Circumference refers specifically to the distance around a circular object or body part, such as the waist or head. While circumference is a type of measurement that can be included in anthropometric assessments, it does not encompass the entire range of size, weight, and proportions measurements, which is why it does not serve as a complete answer.
