Too detailed. First of all, introduce the general size of bedding: generally divided into three categories: 1. Single (child), 2. Twice the normal size, 3. Double plus size 1, single (sub): Zhang; 200*230 cm quilt cover: 150*200 cm or 160*200 cm (this size is suitable for adults to use in summer quilts, but when used in winter quilts, they often feel the air on their feet. The size of adult single winter quilt is preferably 180*220 cm or 180*2 10 cm, and the quilt cover is preferably the same size or slightly larger, such as 200*230 cm. ) pillowcase: 74*48CM (inner diameter) (2 pieces) The four-piece set of a general high-end children's bed includes a pillowcase and a pillow. The size of the pillow is generally 45*45CM or 50*50CM (both refer to the inner diameter). 2. Common specifications for two people: sheets: 230*250CM or 245*250CM or 250*250CM (the slight size difference mainly depends on the width of the cloth used by the manufacturer. For example, if the width of the cloth is 235CM, then if the sheet is a whole sheet, the maximum length of the two sides can only be 230CM (because there are still seams to be made), and the length of the other two sides can be determined at will. ) quilt cover: 200*230CM pillowcase: 75*48CM (inner diameter) (two) This specification can be used for 1.5m or 1.8m beds ... Take a four-piece suit with 230*250CM sheets as an example and jump on 1.5 m beds. 245*250CM means 50CM on both sides and 45CM at the foot of the bed. Generally, plates of this size will be designed with rounded corners, otherwise there will be two corners dragging on the ground. Similarly, the size of1.8m bed is 230*250, that is, 35cm on both sides and 30cm on the foot of the bed. Whether this size is suitable for 1.8m bed mainly depends on the size of the quilt you choose. If it is 200*230, it is very suitable; If it is 220*240 or other sizes, you have to choose other sizes. 3. Double size: bed sheet: 240*270CM quilt cover: 220*240CM pillowcase: 74*48CM (inner diameter) (two pieces) Bedding of this size is generally only used for beds of 1.8 * 2m or wider. Because the bed sheet is relatively large, the specification of modern family bed is1.2m. The size of the double bed is 1.5 m *2 m or 1.8 m *2 m (of course, some old double beds are 1.35*2 m), and then look at your quilt. This is very important, because the paper can be bigger or smaller, which is not very important. Just the difference between hanging more and hanging less. However, if the quilt cover is too big or too small, it will be rolled into a ball in the quilt cover or covered empty. The specifications of quilts vary according to the types of quilts: 1. Traditional hand-made quilts: the single size is 1.67m * 2m (equivalent to 5 feet *6 feet), and the double size is 2m * 2.3m (equivalent to 6 feet *7 feet). 2. Finished quilts bought in the market: single person.
