Should a duvet cover be the same size as the comforter?
On One Hand: Size Match If Buying From the Same ManufacturerPurchasing a duvet cover from the same manufacturer as your comforter will be size appropriate. Sizing is the same for duvet covers as they are for comforters, which are twin, full, queen and king. Sizes will match up when buying from the same company, so there will be no need to buy bigger or smaller for a match.On the Other: There Are No Standard Measurments to Go byAccording to Classicduvets.com, “There are no strict set of standard measurements…” for king, queen, full or twin beds. If not buying the two items from the same manufacturer, the duvet cover may be bigger or smaller than originally intended. You might have to measure for a correct fit.Bottom LineA duvet cover should be at least the same size as, if not bigger than, the comforter. A smaller duvet cover will bunch up the comforter so that it will sit unevenly on the bed.
