In my latest trip to the supermarket, I picked up a couple of products that I hadn’t bought for a couple of months, maybe four, but no more than that. I was stunned to see how much these products had shrunk in such a short period of time. The Pepperidge Fram Milano Cookies were much smaller, maybe 20%. The Leggo toaster waffles weren’t even waffle size any more.
I had already noticed how frozen pizzas had become smaller. A year ago, maybe a little more, I didn’t have a pan big enough to hold a DiGiorno pizza, which unlike some other brands that you can put right on the oven rack, requires a pan for cooking. The pizza that didn’t fit in my pan once now does with room to spare, and I’m pretty sure that the pan hasn’t grown.
I’m sure there are many other items that have experienced the same shrinkage, even as the prices for them have gone up. For the three food items above, none of the packaging says “Now, smaller and less for your money!” Oh, maybe its buried in fine print somewhere, but that’s not acceptable. I remember the TV ads that proclaimed that familiar products were better than ever; I expect the same transparency when they are worse.
Shrinkflation without transparency is unethical: false packaging, a bait and switch. I know the counter-argument: the package has serving amounts and total weight, but it doesn’t doesn’t say “Now, cookies 25% smaller!” That’s what consumers have a right to know.

Make it a health thing. Fewer calories for the same price! 🙂
I was thinking the same thing:
I love Milano’s. But I could lose a few pounds. They’re doing me a favor.
So, sort of like a restaurant sign I once saw.
“All-you-can-eat $15”
“All-you-should-eat $8”
There’s a good subreddit for keeping track of shrinkflation: https://www.reddit.com/r/shrinkflation/
Also, this is from last year but one retailer in France took the ethical route and informed its customers with “shrinkflation warnings”: https://www.foxbusiness.com/lifestyle/supermarket-adds-shrinkflation-warnings-over-dozen-products
The one I remember most was perhaps a decade ago. Wheat Chex, my sister’s favorite cereal, always came in a 16 oz box. One day, I went to the store and it was in a 14 oz box at the same price.
I was not a happy camper.
Coffee at some point went from a pound can to 12 or so ounces. I forget which brand of orange juice where the half gallon jug is now 59 ounces.
Maybe a lot of folks don’t notice things like this. Cost conscious consumers always do, sooner or later. And we remember that General Mills was willing to shrink a box of Wheat Chex. It doesn’t inspire trust and confidence in them.
Absurd, but at least your examples are standalone products!
Shrinkflation is even more frustrating for cooking-and baking-related ingredients- recipes are often built/written around the sizes products come in. You might make a recipe that calls for a can of cream of mushroom soup, but a can isn’t a can anymore. And a cake baked from a box mix will produce shorter layers than before.
