The difference between a hardcover and a paperback usually lay in the cover, waist, spine, inner pages, and print quality. Cover: The cover of a hardcover book is usually more beautiful and has decorative patterns or pictures while a paperback book usually does not. 2. Book waist: The waist of a hardcover book is usually thicker than a paperback book. Information about the book such as author, publication date, and publishing house is printed on it. Spine: The spine of a hardcover book is usually smoother while a paperback book usually has decorative ridges. 4. Inner pages: The paper used in hardcover books is usually more exquisite and the printing quality is higher. The paperbacks were usually printed on ordinary paper and had relatively low quality. 5. Print quality: Because hardcover books require higher printing quality to ensure the aesthetics and durability of the book, their printing colors are brighter, the text is clearer, and the page numbers are neater. On the other hand, paperbacks were usually of lower print quality. Generally speaking, hardcover books were more exquisite and suitable for collections or gifts. On the other hand, paperbacks were more suitable for general reading and purchasing.
