The utility model provides an auxiliary estimation device for estimating leaf area by using a grid method, and relates to the technical field of leaf area measurement. The upper surface of the lamp box is of a flaring structure; the transparent bearing plate is horizontally arranged in the lamp box and used for bearing a leaf to be measured, and the transparent bearing plate serves as the bottom and forms a groove structure with the flaring end of the lamp box; the pressing cover structure is a transparent plate-shaped structure and is used for pressing and covering a leaf to be measured on the transparent bearing plate on the inner side of the lamp box; and grids for estimating the leaf area are drawn on the gland structure. The leaf is pressed on the transparent bearing plate through the transparent pressing cover structure, and the lamp box with the illumination structure is used for illumination, so that the area of the leaf can be directly estimated through a grid method by clearly combining the grids fo
