Why this pair matters

Full and Queen differ in both axes, making the Queen’s additional width and length relevant to rigid frames and fitted bedding.

The figures above are calculated from the identified dimensional records, not from rounded display conversions.

Compatibility decision

Queen is seven inches wider and five inches longer using the sourced US conventions in this dataset.

Rigid frames, enclosed bases, fitted sheets and protectors should be selected from finished product measurements and depth—not from the closest name.
