Is there any ratio for size of object in Convex mirror and real size of object ?

Your question is not clear. 
 
But, the ratio of size of image to size of object is called magnification of mirror.

For convex mirror, the magnification will always be positive and less than 1, because the image formed by convex mirror is always virtual, erect and diminished (i.e. less than the size of object) irrespective of the position of object in front of it.
