Shrinkflation Glossary
Key terms and definitions to help you understand shrinkflation and become a smarter consumer.
Shrinkflation
A portmanteau of 'shrink' and 'inflation.' The practice of reducing product size or quantity while maintaining or increasing the price. The effect is equivalent to a price increase but is less visible to consumers.
Example
A bag of chips drops from 10oz to 9oz while staying at $4.99.
Skimpflation
Similar to shrinkflation, but instead of reducing quantity, companies reduce quality. This includes using cheaper ingredients, thinner materials, or reducing service levels while keeping prices the same.
Example
A restaurant reduces portion sizes or uses lower-quality ingredients without lowering menu prices.
Unit Price
The price of a product per standard unit of measurement (per ounce, per count, per 100 grams, etc.). Unit prices allow consumers to compare value across different package sizes and brands. Usually displayed on shelf tags below the total price.
Example
A 16oz jar at $4.00 has a unit price of $0.25/oz, while a 12oz jar at $3.50 has a unit price of $0.29/oz.
Downsizing
A general term for reducing product size. In the context of consumer goods, it's often used interchangeably with shrinkflation, though downsizing can also refer to legitimate product line changes.
Example
A company downsizes its 'family pack' from 24 items to 20 items.
Grocery Shrink Ray
A humorous term popularized by consumer advocacy blogs describing the phenomenon of grocery products getting progressively smaller over time. Imagines companies using a fictional 'ray gun' to shrink products.
Example
"The grocery shrink ray struck again—my cereal box is two inches shorter than last month."
Stealth Inflation
Price increases that are hidden or disguised from consumers. Shrinkflation is a form of stealth inflation because the effective price increase (less product for the same money) isn't visible on the price tag.
Example
A company redesigns packaging to hold less product while making it look the same size.
Consumer Price Index (CPI)
A measure of the average change in prices paid by consumers for goods and services over time. Published monthly by the Bureau of Labor Statistics. The CPI does attempt to adjust for package size changes, but this isn't visible to shoppers.
Example
The CPI rose 3.2% year-over-year, indicating general price inflation.
Price Point
A specific price at which a product is sold, often chosen for psychological reasons. Common price points like $4.99 or $9.99 are considered more attractive than round numbers. Companies use shrinkflation to maintain popular price points.
Example
Keeping a product at the $4.99 price point by reducing size instead of raising price to $5.49.
Package Redesign
Changes to product packaging, including shape, materials, graphics, and labeling. Often used as cover for shrinkflation—companies introduce a 'new look' that happens to contain less product.
Example
"New Look, Same Great Taste!" on a box that's 15% smaller than before.
Slack Fill
Empty space in a package beyond what's needed for product protection or settling. While some slack fill is normal (chips need air cushioning), excessive slack fill can mislead consumers about the quantity inside.
Example
A chip bag that's 60% air.
Net Weight
The weight of the product itself, not including packaging. Required by law to be displayed on food products. Comparing net weights over time reveals shrinkflation.
Example
Net Wt. 13 oz (368g) printed on a cereal box.
Serving Size Manipulation
Changing the defined serving size to make nutritional information appear better or to obscure shrinkflation. If a bag contains fewer servings because it shrunk, changing the serving size can hide this.
Example
Reducing serving size from 30g to 28g so the bag still claims the same number of servings despite containing less product.
Value Size
Larger package sizes marketed as offering better value per unit. However, value sizes aren't always the best deal—always check unit prices, as shrinkflation affects large sizes too.
Example
A 'Value Size' that costs more per ounce than the regular size due to recent shrinkflation.
Private Label
Store brands or house brands created for a specific retailer (like Kirkland for Costco or Great Value for Walmart). Private labels often resist shrinkflation longer than national brands and can offer better value.
Example
Choosing the store-brand cereal that maintained its original size over the name brand that shrunk.
Inflation Rate
The percentage change in prices over a specific period, usually expressed annually. The inflation rate measures how much the purchasing power of money has decreased. Shrinkflation adds hidden costs on top of the official inflation rate.
Example
If inflation is 4% and shrinkflation adds another 5% effective cost, consumers are actually paying 9% more for the same amount of product.
