What paper should China use for calligraphy? What size paper should I use?

The letter in the middle is a relatively small word, usually called "the size of a walnut", so you don't need to use too much paper. If you use rice paper, you can cut it with four feet and six pieces (that is, cut a four-foot rice paper into six pieces).

As for what kind of paper to use, it mainly depends on what kind of situation you belong to. If you are a beginner, you don't need to use good paper. Just buy some yuan book paper and practice calligraphy. If you have a certain foundation, you might as well use better paper-Xuan paper to write. China's calligraphy and painting paper is Xuan paper. Pay attention to buying rice paper. If you just want to practice calligraphy, you might as well buy Xuan paper marked "calligraphy and painting paper", which is specially for people who practice calligraphy and is cheaper. Other kinds of rice paper, such as "cotton", "skin cleansing" and "extra clean", are used for painting, which is expensive and unnecessary to waste. It's not too late to use paper when practicing.
