Sumario:The objective of this work was to adjust traditional models of hypsometric relations for homogeneous candeia stands, under different initial spacings. Ten models were adjusted for hypsometric relations. The assessment criteria obeyed the highest determination coefficient and the lowest standard error of estimate in percentage. The F test was also evaluated, as well as the significance of the regression coefficients, the graphical analysis of the residues and the identity test when the same model was selected for different treatments. It was observed that, over time, the hypsometric curves reduce their tilt, move to the right and elevate, reducing the interval among them from the sixth year. The traditional hypsometric relation models as Henricksen, Stofells, Assman, Trorey and Curtis are efficient to estimate the total height of candeia in homogeneous stands and under different initial spacing in Minas Gerais State, Brazil
