The objective of this work was to estimate the total leaf area of banana, cultivar Prata Anã, according to the linear dimensions of the third leaf, such as the length and the width and the total number of leves in the inflorescence emission. The linear regressions were determined considering total leaf area of each plant (AFT) such as dependent variable and the length (C) and the width (L) of the third leaf, the product of CxL, the total number of leaf per plant (N) and the product of CxLxN as independent variables. The best linear model that estimated the total leaf area (AFTe) of banana 'Prata Anã' at the level of 5% of significance with R² of 0,89 was the equation AFTe = 0.5187 (CxLxN) + 9603.5.
