Number + 幅 + Noun
The measure word 幅 (fú) is used to count flat items such as paintings, scrolls, photographs, and pieces of cloth or fabric. When referring to artwork or textile items, Chinese requires a measure word between the number and the noun, and 幅 is the appropriate choice for these categories. For example, 一幅画 means "one painting."
