Great question! When it comes to book covers, there are a few recommended dimensions and file formats to ensure that your cover looks its best.
For dimensions, the standard size is usually around 6 inches by 9 inches for a paperback book. However, it's always a good idea to check with your chosen publisher or printing company for their specific requirements. You'll also want to consider the resolution of your cover image. A resolution of 300 DPI is generally recommended for print covers to ensure that the image is crisp and clear.
As for file formats, most publishing platforms accept either JPEG or PNG files. JPEG files are usually smaller in size and great for photos, while PNG files are better for graphics or illustrations with transparent backgrounds.
It's important to note that your book cover is often the first thing a potential reader will see, so it's worth investing time and effort into making sure it looks professional and eye-catching. If you're not confident in your design skills, consider hiring a professional cover designer or using a platform that offers customizable templates.
