Standard Height and Weight Measurement Procedure for Children
For the most accurate measurements it is highly recommended that assessments be conducted on hard
surface floors (i.e. gym floor, tile floors) and avoid floors that are carpeted.
1.Preparation of the Child
The child should be asked to remove as much outerwear as possible. Regardless of the clothing worn, the child should be asked to remove his/her shoes and will be measured either barefoot or wearing socks.
Additionally, the child will be asked to empty his/her pockets and remove all jewelry or other objects.
. The child will be asked to remove eyeglasses, hair barrettes, and ties or rubber bands, if possible, so that accurate height and weight measurements can be obtained.
One measurement of weight and two measurements of height should be taken and entered on each
child. Because the measurement of height requires greater skill to perform correctly, two measurements are required in order to reduce error and therefore obtain a more accurate calculation of BMI. If the difference between the two height measurements is greater than one inch, then a second set of two height
measurements should be taken to try to obtain values within one inch of each other
NOTE: If metric measures are used, the difference between the two height measurements should be no
greater than 2 centimeters.The measurements of weight and height should be measured in rotational order, as follows: 1stheight, weight, 2ndheight. If the difference between the two height measurements is greater than one inch (per above), then the child must be re-measured.
For the measurement of weight, the child will be asked to step up backwards onto the scale and stand still over the center of the scale with body weight evenly distributed between both feet.
In order to ensure confidentiality and to prevent the child from seeing his/her weight, it is required that the child step on the scale backward facing away from the readout. The childs arms should be
hanging freely by the sides of the body, with palms facing the thighs. The child should hold his/her
head up, and face forward.Weight is recorded to the nearest 0.2 pound using the recommended scale with a digital readout . Depending on the type of scale used, record to thenearest fraction of a pound, whole pound, pounds and ounces, kilograms or grams.
4. Height Measurement
For the measurement of standing height, the child will be asked to stand with his/her back against the board. The back, scapulae and buttocks are in contact with the vertical board if possible, or whichever part of the body touches the board first. The weight of the child should be evenly distributed on both feet. The child will be asked to place the legs together, bringing the ankles or knees together, whichever comes together first (often they will come together simultaneously). If the child has knock-knees, the feet are separated so that the medial borders of the knees are in contact, but not overlapping.
The child is instructed to stand erect (stand up straight and look straight ahead). The child's position should be verified from botht the FRONT and from the LEFT side of the Body.Next the childs head is positioned in the frankfort Horizantal plane. In this position this position, an imaginary line can be drawn from the bottom of the eye socket (orbital margin) to the external opening of the ear (external auditory canal).
The child will be asked to inhale deeply and hold his/her breath WHILE MAINTAINING the head and body in the same position. Sometimes a child will either lift his/her head or pull up onto the toes when taking the deep breath. If this happens, the measurer will need to re-position the body and head before taking the measurement.
The moveable headpiece is brought onto the upper most (superior) point on the head with sufficient pressure to compress the hair.After the measurement is obtained the child should be told they no longer need to hold his/her breath. The measurement is recorded to the nearest 1/8thof an inch, (or nearest 0.1cm, nearest 1/16 inch, or nearest mm, depending on the stadiometer used).
