Why this pair matters

Queen means a large North American/Australian size but can mean UK Small Double. This page compares the labels without declaring one worldwide Queen.

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

Compatibility decision

US and Australian Queen examples are close; UK Queen usage points to the much smaller Small Double convention.

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