For approving a marriage, there must be not less than 18 Guna matches between the bride and the grooms horoscopes. If the matching Gunas are less than 18, then the proposed match is not approved. If 18 to 25 Gunas match, then it is demed as a good marriage. A best match ensues when 26 to 32 Gunas match.

How important is Guna matching?

During Kundli matching, the horoscopes of the bride and groom are matched to ascertain whether their married life will be happy and successful. If 18 or more points match, it makes a good marriage and if the matches are below 18 points, then the marriage is not approved by astrology.
