it's depend on angle of contact that is the angle between the meniscus and the containing walls of a column of liquid measured from the vertical wall below the surface of the liquid to the position of the tangent to the meniscus at its point of contact with the wall.
or
When the liquid is in contact with solid, the angle between the solid surface and the tangent to the free surface of liquid at the point of contact, measured from inside the liquid is called the angle of contact.
