Children over the age of 2 years, who are cooperative and able to stand
alone should be weighed using a platform scale.
Equipment:
Use a calibrated beam balance scale or a digital scale with "strain
gauge" mechanism that is accurate to 100 grams or 1/4 pound. A spring-type
bathroom scale should NOT be used... with repeated use, it will
not maintain the necessary degree of accuracy.
Child and Positioning:
Bulky clothing, outer clothing, and shoes should
be removed. (It is best if clothing is standardized; some clinicians
have children wear a paper gown for weight measurements.) The child
should be centered on the scale's platform, touching nothing.
Measurement:
Record the measurement to the nearest 100 grams or 1/4 pound and record
any conditions that might have interfered with an accurate weight
(e.g., child was moving).
