Should a Comforter Be Bigger Than the Bed?

A comforter is often slightly larger than the bed to improve coverage and drape. Extra width and length help the comforter hang evenly over the sides, prevent cold spots, and accommodate movement during sleep.
This practice is less common in Europe than in the United States. In many European bedrooms, comforters are sized closer to the mattress for a neater look. The ideal size depends on mattress height, sleeping habits, and whether a tailored or more generous style is preferred.
