4. Measuring Infant Length: Quality of Measurements

The measurer at the feet should read aloud to the recorder the length measurement to the nearest 0.1 cm or 1/8 inch.

The length should be recorded on the data form as soon as it is completed.

Then the infant should be repositioned and the length measurement repeated and noted in writing.

After the infant is removed from the lengthboard, the length measurements should be compared and they should agree within 1 cm or 1/4 inch. This is the tolerance limit of this measure.

If the difference between the length measures exceeds the tolerance limit, the infant should be repositioned and remeasured a third time. The average of the two measures in closest agreement is recorded.
