How old was Romeo if Juliet is 13?

While Juliet's age is placed at approximately two weeks before her fourteenth birthday ("a fortnight and odd days") on Lammastide, a church feast which occurs on August 1, Romeo's exact age is never revealed. It has always been assumed that he was older than her, and the text tends to bear this out. The audience should consider Romeo to be of equal age as the men who are his peers, including Mercutio, Benvolio, Tybalt, and Count Paris, yet some elements of the text place Romeo both younger and older than the other young men of the play. In Act III, Scene 1, Tybalt refers to him as a "boy," but this may be more of an attempt at insult rather than a reference to age. In Act V, Scene III, Romeo refers to Count Paris as "Good gentle youth," suggesting Romeo may be older than Paris. More likely is that Shakespeare uses these terms interchangeably and that these men are all in the same age range. That Juliet is so young is somewhat surprising. While some nobility might seek to marry their daughters when they are as young as 13, the typical age of marriage during Renaissance times was older, and Lord Capulet seems to acknowledge this when he suggests to Paris that he wait at least "two more summers" before marrying Juliet.
