Indicator level for vertical and horizontal, characterized in that it is essentially constituted by a variable squaring rule, which has housed three bubble levels embedded in said rule, having provided two windows that make the levels visible, arranging two of these on one side and the third one in the contiguous one at different height, so that the axes of the levels of the same face are arranged orthogonally and the third level coincides in its disposition with one of the other two, so that there are a couple of levels whose axes are perpendicular to the length of the ruler, and these levels have to be placed on contiguous faces and the third has its axis parallel to the length of the ruler.
