What is different between oversize and midsize tennis racquets?

[kapchipxp]

Instead of saying overhead, you should say oversized. The larger (oversized) racquets have a larger sweetspot, and generally more power. You are less likely to hit poor shots near the frame with the larger head racquets. Hardly anyone plays with smaller head racquets now.

Now that you provided the question along with the answer, let me return with a question: Why would anyone use a midsize frame then? ;)

Its gotta be from the massive amount of spin that is now hit at the pro and even the rec level from the poly strings. There are still plenty of purists left with Eastern grip forehands like myself that love the smaller headed frames.

Given the same weight and balance, a midsized racquet will be more maneuverable than an oversized racquet. By maneuverability I mean the ability to adjust a swing that has already been launched in order to meet the ball. I am currently using an 11.5 oz. 105 - which is a small oversize. What I mainly like about this racquet is that it is very good for hitting the ball on the short hop, which, because I am old and slow, is something I do a lot.

What size are you calling "smaller"? If you are talking about midsize (85-100 or so), this is a very popular racquet size. Really depends on the level of players you are talking about too. Most advanced male players use the "smaller" frames. IMO

This is absolutely contrary to my experiences with our tennis scene here. Everyone thinks they are more advanced than perhaps they really are and go with frame sizes from 90-100 at the largest.
In fact frame head sizes of 105+ sq in are lovingly referred to as Granny Rackets around here.
I know Andre Agassi used a 107sq in frame for many years and he did okay for himself. The Williams sisters also use larger head sizes, for a while even over 110 sq in. They also did okay for themselves.
Ya know, different strokes for different folks.
A racket is just a tool of the trade, and not everyone approaches the same job in the exact same way.
