Standard Hardback Book Sizes in the UK

The most common hardback book sizes in the UK are based on the trim size, which is the size of the book after it has been trimmed and bound. The two most common trim sizes are Royal and Demy.

Hardback and paperback books in the UK share some size standards, but there are some key differences. Hardback books are typically larger and heavier than their paperback counterparts, as they are bound with a hard cover and often have higher-quality paper and printing.

Size Hardback (mm) Paperback (mm)
Royal 234 x 156 198 x 129
Demy 216 x 138 198 x 129
Large Format 273 x 203 248 x 171

When choosing a hardback book size, consider the content and intended audience. For most fiction and non-fiction books, the Royal trim size is a safe bet. However, for books with a focus on visual content, a larger size may be more appropriate. Working with a professional publisher or printer can help ensure that the chosen size is suitable for the book's content and production needs.

Understanding the different hardback book sizes in the UK can help authors, publishers, and readers make informed decisions about the books they create and enjoy. Whether you're a seasoned publishing professional or a first-time author, knowing the ins and outs of hardback book sizes can help you navigate the complex world of book production with confidence.
