The standard bed sheet size for a queen bed at Changyi Baiyi Textile Co., Ltd. includes a fitted sheet (60x80+16 inches), flat sheet (90x102 inches), and two pillowcases (20x30 inches). These measurements are optimized for universal queen mattresses, with elasticized edges on fitted sheets to prevent slipping. The company’s polyester sheets are engineered for durability, with tight weaves that resist stretching and fading. While the website highlights these standard sizes, the factory can produce non-standard dimensions via ODM services for special projects.
