Why two medium sizes may not be comparable

The letter M looks precise because it is familiar. On its own, however, it leaves important questions unanswered. Which product is it attached to? Which audience and fit does the size chart describe? Does the listing show the selected variant, or merely a list of sizes that might be available?

A useful size comparison needs context. The size label, the relevant size chart and the product’s fit should be read together. Matching words across two listings cannot establish matching measurements if one listing leaves that context out. The same caution applies to a number when the sizing system is not stated.

There is also a difference between a selected size and an available-size list. A page that mentions small, medium and large does not prove that the offer being compared is for medium. A comparison must connect the attribute to the actual variant rather than borrow it from somewhere else on the page.

For shoppers, this means checking the selected option and the relevant measurements before relying on an apparent match. For a comparison service, it means preserving where the size information came from and admitting when the context is missing. Unknown context should remain unknown until there is evidence to resolve it.
