We have reported on various packaging and product tricks like shrinkflation, skimpflation, slack-fill, and measuring cap changes, but we haven’t talked about the size of the holes through which a product is dispensed. Some people have suggested the hole is getting bigger, so you wind up using more. We even got an inquiry from a New Zealand consumer TV show asking about this.
So MrConsumer checked his bountiful stock of toothpaste and found two tubes to compare. While not a perfect comparison because they are different varieties, it gives you a good sense if the allegations are true at least for Colgate.
The tube on top is Colgate Optic White with an expiration date in 2023 while the one beneath expired in 2013 — a 10 year difference.

Checking the diameter of the holes reveals something surprising.

They are both 8mm wide. So at least with respect to these varieties of Colgate over a decade, the hole did not get bigger.
I am not able to compare Crest tubes because I do not use the brand generally and don’t have a supply of old ones. Maybe some readers do and can take measurements and report them in the comments.
Even if it is just a perception that toothpaste holes are too big and may be getting bigger, a product called Screwge was sent to me to make toothpaste tubes last longer. These are specially-made replacement caps for both Colgate and Crest with only a tiny hole in them, so you use much less.

With respect to other products, the hole on some eye drop bottles is larger than it needs to be because the drops wind up dripping down one’s face.

Dr. S, a regular reader and optometrist, wrote in to say you can screw on a cap replacement called Nanodropper that dispenses a smaller drop to reduce waste. It is compatible with most, but not all eyecare products.
And clearly, the hole on Dawn dishwashing liquid has gotten larger over the years.
