Runs small

An item runs small when it fits smaller than its size chart says, so shoppers usually need the next size up.

An item runs small when it fits smaller than its size chart promises: a shopper whose measurements say M finds the M tight. The usual advice is to take the next size up. The opposite is "runs large", where shoppers go down a size.

A slim cut, a compressive fabric or a stretch-free denim can all make an item run small on purpose. Said alone, "runs small" is half a sentence: it tells shoppers something is off, not how much or what to do.

On a size chart

Two steps of the five-step fit scale sit on the small side: "Runs slightly small" and "Runs small". Pair them with a fit note that names the cut and says what to do. From Ruban Size's templates:

Fit notes that help has more examples and the wording traps to avoid.

In Ruban Size

Find my size reads the scale. Before comparing, it moves the shopper's measurement up by 0.2 of a size step for "Runs slightly small" and by 0.55 for "Runs small". On the women's tops template, where the chest step is about 6 cm, that is 1.2 cm and 3.3 cm. The answer then adds "This item runs small: we took it into account."

On the Fit plan, returns by size flag a size once it has 3 size returns with at least 70% saying too small, and one click moves the chart's scale one step. Reading your returns by size walks through it.
