Background: Height measurement was very important to toddlers and preschool children. Deformity or certain abnormality in toddler and preschool children caused height measurement was not possible. Arm span was known to be an alternative anthropometric parameter to height. Ration between height and arm span varied in different race, age, and sex. Aim: The study was aim to know the ratio between height and arm span in toddlers and preschool children. Methods: This was a cross-sectional study with observational analysis. This research was held in March-May 2015. The subject was toddlers and preschool children age 1-5 years. Height and arm span data was acquired by doing measurement to subjects. Statistical test used linear regression test. Results: The number of subjects were 197children aged 1-5 years. Linear regression test showed the ratio for male toddlers and preschool children aged 13-24 months was Height=27,793+0,685 arm span, aged 25-36 months was Height=21,364+0,771 arm span, aged 37-48 months was Height=32,157+0,686 arm span, aged 49-60 months was Height=54,681+0,461 arm span. The ratio for female toddlers and preschool children aged 13-24 months was Height=49,398+0,367 arm span, aged 25-36 months was Height=20,185+0,796 arm span, aged 37-48 months was Height=32+0,674 arm span, and aged 49-60 months was Height=13,861+0,884 arm span. Conclusion: Mean height for male toddlers and preschool children was 91,4±10 cm, while mean height for female toddlers and preschool children was 89,2±10,4 cm. Mean arm span fot male toddlers and preschool children was 89,6±11,6 cm, while mean arm span for female toddlers and preschool children was 87,2±11,2 cm. Equation based on divided age predicted height better than equation based on the whole age 1-5 years. Key Words: Height, arm span, toddler, preschool children, anthropometr
