Gaining Knowledge, Losing Bliss
Professionals and designers need more information and details about how design their cover. First, we cannot emphasize this enough:Three #1 Rules of Cover Design
- Do not try to be precise about placements of items on your cover.
- Do not try to place anything on the spine
- Leave lots of bleed. You cannot be too conservative moving elements away from the edge.
All about Covers
- We HIGHLY recommend your covers be created as RGB .jpg files
- We HIGHLY recommend you leave plenty of room around your cover edges so important items (heads, text) are not trimmed.
Living on the edge is bad
Your mother probably told you this and hopefully you listened. If you set up your image to run to the very edge of the fold or crop guides, you will be disappointed. Binding equipment can easily have 1/4" fluctuation between cycles. Please compensate for this fluctuation.Cover Dimensions
Perfect Bound Softcover
All softcover books have 1/8" (3mm) bleed on all edges, so the cover should be .25" (6mm) larger than the final book size.Spine width for softcover books is 300 pages (150 sheets) per inch, or 118 pages (59 sheets) per cm.

11x8.5 Dust jacket
I like the new interface for the covers, and I see now that there is an option for the dustjacket. What is the total size dimension for the dustjacket cover including the inside flaps? I can only find a template for the full-wrap cover. I've got plenty of bleed, and everything looks fine so far. If you have that template, or could tell me the total length and width dimensions to upload for the dustjacket cover, I think I can get it done.
Thanks!

Cover for 14x11 portfolio book
And when I export to PDF, should the PDF be in spreads?
Re: Cover for 14x11 portfolio book
Greetings from viovio and thanks for your interest.
Just upload your cover as normal and we'll take care of the rest :) We prefer one complete PDF or separate .jpg files. We recommend your images be at 300 dpi.
For all our trim sizes we recommend you make the cover images as well as the interior page images 1/4" larger than your book size. For example if you plan to create an 8.5x11 book the cover image as well as interior pages would be 8.75x11.25 (at 300 dpi).
Most importantly, keep all important items (people, heads, text,borders) away from the outer 1/2" on all sides.
If you have any questions please let us know!

Re: Cover for 14x11 portfolio book
I could create a single image twice as wide as the actual cover and use the full wrap cover option, but with the 14x11 wire-bound portfolio book that I want to make I suspect there would be problems with the "spine" side trim.
And is there a way of printing on the inside of the front and/or back cover?
Re: Cover for 14x11 portfolio book
I kept it simple and followed those instructions, but on the cover preview the hardcover turn-in bleed area cuts waaaaay into my image.
That is what I don't understand... support says to do one thing, but then the preview shows that everything will get cut off.
Tell me this: If I was going to make both a hardcover and a softcover of the exact same book, would I have to shrink down the image for the hardcover to fit inside those lines, even though the sentence above in quotes says what it says?
Do you see what I mean? Am I missing something here?
Re:
One of your assumptions is incorrect - "when both books (hardcover and softcover) are printed, the cover image is the same size on both"
An 11x8.5 softcover needs a file that has an extra 1/8" on each edge. That is pretty straight forward.
An 11x8.5 Imagewrap hardcover (technically called the 'case') is 1/4" bigger than the trim size. Also, and this is a key, Imagewrap hardcovers need an extra .5" of paper on each edge to wrap around the edges of the book. In order to maintain aspect ratio as best we can, we adjust the .5" some (a touch less on the vertical, and touch more on the horizontal).
So, to allow one to order a book in different bindings, we resize the 11.25x8.75 cover to get large enough cover we can wrap around the cardboard.
For your book, the exact size of the Imagewrap hardcover file turned out to be 24.17"x9.67" - 11.98" wide for the front and back, and .21" for the spine. The vertical needed an extra .58" for the oversized case and extra paper to wrap around the edge (technically called "turn in").
The exact dimensions for the image wrap vary and change as our manufacturing process changes. This is why we don't give exact numbers for the Imagewrap hardcovers.
Follow the guides we give you and all will be fine. So the simple answer, do not let important elements go into the yellow, orange or red zones, and everything will be fine.
