Hi Ruben, Yes 300 dpi is great and will ensure your images look great as a printed image. Here is a link to our page on covers https://www.prestophoto.com/help/Book+Cover+Specifications Check out that page and if you have any questions please send a note to support

Hi, when choosing ImageWrap, how can you calculate the Cover/Back size? (I'd like to create my own photobook) Since this is my first book I am designing, do you have any tips I should pay attention to? 300 dpi, CMYK, 3mm margins in every corner. What else?

If you could send me a e-mail as well to ruben@rubencress.com that would be great.

Thanks in advance,

Ruben
