1. Height should be measured without shoes.

2. The individual’s feet should be together, with the heels against the wall or measuring board.

3. The individual should stand erect, neither slumped nor stretching, looking straight ahead, without tipping the head up or down. The top of the ear and outer corner of the eye should be in a line parallel to the floor (the “Frankfort plane”).

4. A horizontal bar, a rectangular block of wood, or the top of the statiometer should be lowered to rest flat on the top of the head.

5. Height should be read to the nearest inch or 0.5 cm.

1. Use a beam balance scale, not a spring scale, whenever possible.

2. Periodically calibrate the scale for accuracy, using known weights.

3. Weigh the subject in light clothing without shoes.

4. Record weight to the nearest  lb or 0.2 kg for adults and  lb or 0.1 kg for infants. Measurements above the 90th percentile or below the 10th percentile warrant further evaluation.
