Shrinkflation: When the Price Stays the Same but You Get Less
Smaller packs at the same price are a quiet way to pass on rising costs. Here is why firms do it and how to spot it.

A chocolate bar that is a few grams lighter, a cereal box with a deeper dent at the bottom, a toilet roll with fewer sheets. The price tag has not changed, so many shoppers do not notice.
Shrinkflation is a price increase in disguise.
I Why firms shrink instead of raising prices
Shoppers notice and react to price changes far more than to changes in quantity. Many products also sit at familiar price points that feel important to keep. Reducing pack size passes on higher ingredient, packaging, and energy costs with less customer resistance.
II Its cousin: skimpflation
Sometimes the size stays the same but the quality drops: cheaper ingredients, thinner materials, or reduced service. This is harder to measure and even harder to spot.
III Is it counted in inflation?
Statistics agencies that measure inflation generally adjust for changes in quantity, so a smaller pack at the same price is recorded as a price increase. Quality changes are more difficult to capture.
IV How to spot it
- — Use unit pricing — price per 100 g, per litre, or per sheet — shown on shelf labels
- — Compare the weight on the pack, not the size of the pack
- — Watch for new packaging, which often accompanies a size change
- — Check own-brand alternatives, which may not have shrunk
V Regulation
Some countries now require shops to display unit prices clearly, and a few have introduced or debated rules requiring labels when pack sizes shrink. Unit pricing remains the most reliable tool for comparison.
