Prince oversize series head sizes

I have a small collection of Prince oversize rackets circa 1980-1984. I am always interested in knowing the actual head sizes of these variations, although all of them are called "110". I searched on the forums and knew that the consensus is that all of them are actually smaller than 110.

I wonder if there are official measurements available for the oversize series? Or if I have the rackets in hand, is there a way I can measure them myself?

My own estimates are as follows:

Boron: I do not have this, but from pictures it looks smaller than POG. 103?
Graphite: I only have the Prince Graphite Tour (from TW), which is 107.
Magnesium Pro: Narrower near the throat, also shorter. 102.
Graphite Comp: Narrower and shorter than POG, but slightly wider than Magnesium. 103.
Precision Graphite: Almost identical as Graphite Comp, but a tiny bit shorter at the throat. 102.
Woodie: The smallest of all. 100?
Pro & Classic: I do no have these two (not much interested).

boron is identical in headsize to the POG OS. i have 2 borons and replaced the grommet set w/ the POG OS grommet set and they fit perfectly.

I have the Mag 110 - it sure looks small doesn't it? I reckon it's about 100sq.in, just at a glance. I haven't seen a Mag 90 up close - I wonder how much extra smaller that'd be?

Well, they aren't exactly the same oval shape, e.g. the Magnesium Pro looks more square near the head and leaner near the throat.

You can still get a good approximation of the area with simple math, it’s just a little more complicated. The formula is X times Y equals area.

First, measure the length of the racket head down the middle. Then divide that length into equal parts (“offset lines”). The more equal parts you use the closer your approximation will be. Measure the width of the racket at each equal point. Add up all of these widths. Multiply this number by the length of the racket head. This number is “Y". Then measure the distance between the “offset lines” (it must be an equal distance between each “offset line”). This number is "X". Now multiply this number by “Y”. Voilà: X * Y = Area. See, simple! :wink:

I looked at a picture from the web. The boron looked smaller. Maybe it's due to the angle?

I see what you mean now but that's quite some work, :)

Prince Graphite Comp

The first generation of Graphite Comp (the one without Series 110 on the side - with individual grommets) has a thinner beam (around 18mm) and a smaller head size (~100-102), while the later model (Series 110 written on the side) has a thicker beam (aound 21-22mm) and slightly larger head size (~102-104).

It shouldn't be squared off at the top. Mag Pros were notorious for changing shape while being strung, and the squaring off thing was one of their favorite tricks. I have a Series 110 that's in pretty good shape, and applying the 'area of ellipse' formula mentioned above (pi x half of width x half of length; Autodidactic was giving you the short version) gives me 102.7 sq in.

You're right, though, racquet heads are not perfect ellipses. If you don't want to go as far as Autodidactic's suggestion, you could get a little more accuracy by assuming that the lower half of the racquet is half of a real ellipse, and the upper half of the racquet is half of a (usually) slightly larger ellipse, figuring the areas of those two half-ellipses, and adding them together. I messed around with it a little but got almost the same results as a simple 'area of ellipse' with too much extra work.

If you have Photoshop and AutoCAD, you can do what Jack & Coke did.
