Changes in height throughout the day after standing are poorly understood, even in morphological sciences. This study evaluated height variations throughout the day in a sample of young Colombian population. Using a stratified random sampling with proportional allocation, diurnal changes in height was evaluated in 55 subjects. Four measurements of size were taken over a day, using a conventional measurer for it. Statistical analysis of the results was performed by testing agreement (ICC). The average age of the subjects tested was 19.5±1.86 years, of which 22 (40%) were male. The average height and weight were 167.1±8.59 cm and 65.8±14.5 Kg respectively. The average loss of height after the day was 9.4±3.12 mm loss in women was 9.72±3.35 mm and 8.95±2.76 mm in men but this difference was not significant (p=0.22). Statistically significant association between weight >78 Kg and height loss in the day >1cm (p=0.18) was not identified. In the range of 06:00 to 10:00 hours came up with the greatest reduction in size, 60%; while from 10:00 to 14:00 hours the decrease was 10% and 30% of 14:00­18:00 hours. Height loss observed in this study was just below that reported in the literature. The knowledge of the changes in height throughout the day should be taken in consideration when diagnosing growth pathologies.
