Organizing books can be therapeutic for book lovers. Here are some unique tips and tricks you must try to upgrade your room decor and better arrange books. Arrange your books by size. Keep the tallest ones at the back of the shelf and short texts in front. 1. You can also use bookends on the shelf to keep the reads from falling over. And sort out your books by categories and genres. For instance, keep fiction books on one shelf and non-fiction, thriller, and biographies on separate shelves to make it easy to find a particular genre book. 2. Whether you want to stack books vertically or horizontally is your choice, but the horizontal style is more stable as it prevents readers from falling over. 3. To make the arrangement aesthetically pleasing, you can keep some decorative souvenirs or art pieces in one section/shelf. This will break the monotony of books and add personality to the room.
