There is no unified standard for kneeling on one knee, whether on the left or right leg. Traditionally, it is more common for people to kneel on the right leg because it is more convenient to wear a ring on a girl's left hand. However, those who agree with kneeling on the left leg believe that the left side is the closest position to the heart and appears more sincere. So when proposing, it's okay to kneel on either the left leg or the right leg.
The significance of proposing on one knee
The custom of proposing on one knee first appeared in Western courts. From knights kneeling down to show respect and obedience to the king, to later men kneeling on one knee when proposing to girls. This approach shows respect for women, allowing them to avoid looking up at them.
Many men know that an essential part of a marriage proposal is to kneel down on one knee with a ring in hand. In such situations where there are many people, kneeling down on one knee requires a lot of courage. But the most important significance of kneeling down to propose lies in the moving words and vows spoken by the other party.
At the same time, this action also showcases the gentlemanly side of the man, demonstrating the level of importance you place on your proposed partner. Because kneeling down on one knee represents the romantic meaning of loving her forever and being willing to love each other until old age.
