Size and weight measurements establish the baseline for monitoring growth.

These measurements can also be used to detect such disorders as failure to thrive and hydrocephalus.

Measurements include head circumference, chest circumference, head-to-heel length, weight, and abdominal girth.

Crib or examination table with a firm surface

Scale with tray and scale paper

Tape measure

Length board

Gloves, if neonate hasn’t been bathed yet

Explain the procedure to the parents if they are present.

Wash your hands and put on gloves if the neonate hasn’t been bathed yet.

Position the neonate supine in the crib or on the examination table.

Remove the neonate’s clothing.

Measure head circumference: Slide the tape measure under the neonate’s head at the occiput and draw the tape around snugly, just above the eyebrows. Normal neonatal head circumference is 13″ to 14″ (33 to 35.5 cm). Cranial molding or caput succedaneum from a vaginal delivery may affect this measurement. (See Measuring neonatal size and weight.)
