Pool Ball Weights

FYI, many years ago, I took a bunch of weight measurements at a local pool hall. Here's a summary of the results from “Ball Weight and Size Difference Effects – Part I” (BD, February, 2012):

To see how much ball weight can vary in typical conditions, I took an accurate digital scale to my local pool hall (“Match Ups” in Fort Collins, Colorado). I weighed the CB and randomly selected OBs (and the 1- ball specifically) in each of eight Valley bar boxes with the assistance and permission of the owners. (Thanks Mike and Nicole!) The CB weights were fairly consistent with an average of 5.89 oz (167 g), a minimum of 5.78 oz (164 g), and a maximum of 5.93 oz (168 g). The OB weights were lighter (2-3 percent on average) and less consistent with an average of 5.75 oz (163 g), a minimum of 5.47 oz (155 g) and a maximum of 5.89 oz (167 g). The lightest OB was a 1-ball, which makes sense based on the extra abuse it takes (but this could also just be coincidence). If the heaviest CB were paired up with the lightest OB, the percentage difference would be about 8%.

FYI, I also have more info and related video demonstrations here:

Thanks for adding. Your measurements seem to be centered more around wear of used balls (CB vs object) and how that affects playability. The purpose for my measurements was to illustrate the weight tolerances across a variety of manufacturers and sets of mostly new/slightly used examples in an effort to dispel any myths regarding the quality control (in terms of weight) of certain phenolic ball manufacturers. As the data shows, the offerings from China and South Korea have very similar weight tolerances than the gold standard Aramith Tournaments and IMO, are slightly better than a new set of Brunswick Centennials which are also made by the folks that bring us the Aramith products. At the end of the day (in terms of weight), a quality phenolic ball is just that, regardless of who it was manufactured by.

One such myth as referenced in another thread:

Most co's would die for consistency and QC like that.

Interesting data. Thank you.

I have been curious as to ball size variances compared to cloth irregularities (wear, debris on surface, minute imperfections in the slate).

Let's say the largest, or least worn OB is at 2.250" and the CB is on the cusp of being out of spec at 2.245", or even so far as 2x out of spec at 2.240", a full 0.010". When these two balls contact each other, the difference in size at center is 1/200".

Will your average/above average player notice how they play? Are there other irregularities on the surface of a well maintained table as great?

Thanks again.

I think the 8% difference in ball weights mentioned above would definitely be noticed by a good player (especially on draw shots and natural angle direction). I'm not so sure about your example numbers, but I suspect that difference would not be noticeable.

They make a much better ball now than Hyatt did.....but Hyatt’s color codes meant something.
Blue Dot was a little heavier....for straight pool players
Red Dot drew a little better....for 9-ball players
Green Dot by Macon was the lightest....could draw table length hitting almost center ball.

Raschig raised the bar...at the ‘89 tradeshow, they were the only ball that stayed within 2 onethousandths off round, even while crossing a stripe or a number.....but the ball, like their Vitelite snooker balls, were lighter than what players wanted.

The ball I won’t buy anymore is the measle...I feel it was a failure.

These are the weights of the various cue balls I have.

Thanks to the mods for making this a sticky! I'll edit the first post in this thread with updated data as I get it.

The lightest OB was a 1-ball, which makes sense based on the extra abuse it takes
The one ball on our nightly ring game table eventually gave up the ghost. It shattered. It had probably had a few collisions with the cinder block wall as there were breakers that consistently hopped the cue ball to the light on the break. Of course the big cue ball out weighed it too.
