A DRAWER DIVIDER
Size references
An age label is not a personal fit result
Read the actual product family and chart before using an age range.
Why a US shoe range such as 9–1 is not a descending measurement
Children’s shoe-number sequences need their named scale.
A tights row uses height and weight together, not age alone
The manufacturer chart’s dimensions stay attached to the selected row.
Chart gaps and overlaps should stay visible
Do not invent a missing row or force a single fit result.
