According to the search results, the dimensions of a queen size blanket are typically 90 inches wide and 90-100 inches long. These blankets are designed to fit a queen size mattress, which is generally 60 inches wide and 80 inches long. It is recommended that a queen size blanket should have 15 inches of overhang on each side and 10-20 inches at the bottom when used with a traditional 60x80 queen-size mattress. However, exact blanket dimensions may vary from manufacturer to manufacturer. It is also important to consider the added dimensions of your body when you sleep, and whether you share your bed with someone who may prefer a larger blanket.
