Kindle Image Size

I'm working on my first Kindle book, so I hope my questions don't sound so simple.

Can someone tell me the max. (width + height) size for a single page?

Some of my pages I want to [b]fill the entire kindle screen/page[/b] with a single[b] image[/b] per page.

Also, If for example my image is say 400px wide, & the kindle is 600px wide (?) will kindle stretch my image? [b]I would rather it didn't resize[/b] the image since I can create the actual size needed before I publish the book as soon as I know the correct sizes.

Thanks,
badken

The answer is "it depends". On Kindle 2, the viewable screen area is 520x622. On Kindle 3 it's 600x800, and on the DX it's 744x1022.

If you have a smaller than full screen image, it won't get resized as long as you specify the image dimensions in the HTML img tag.

The old standard was 450x550; the new standard is 600x800. Either will fill the page.

Given the small size of the Kindle "page" (never mind the iPhone!), I think it's a mistake to try to shrink images. And as the Kindle itself, and the various Kindle apps, have evolved over the past four years, you can't be sure that all of them will treat your smaller images the same way.

(I use square or horizontal images a lot, because that's the natural format of a photograph. In that case, I include a caption beneath it, knowing that they will be separated in the case of people like me who prefer to read on an iPhone held horizontally.)

The best bet in my opinion is if you wanted and/or need control over how your image size will be displayed on the Kindle, depending on which generation of Kindle you want to target, would be to make a fresh original image (with no re-sizing) as close to the desired Kindle image size you want. This is a little hard for me to explain but I will try.

I have over 20 years of printing experience, I have only some experience in digital reproduction, and yet although things have changed a great deal, the basic principles to me are the same. The more you play with a graphic sizing and re-sizing, or producing and reproducing (saving and resaving especially with jpegs, if that is the image format you are using) the more you sacrifice quality. Maybe do some research to find the best image format for your type of image, and also for using the best program/software resources that you may currently have available to you for manipulating your image.

My suggestion would be to try to create your image from the start as close to the original image's size and resolution as possible, and as close to the final targeted size and final resolution you want your image to be for your chosen Kindle generation. If you can create and edit vector graphics as you starting point, I would highly recommend it. However, perhaps scanning your original image in first at you desired target size for your targeted Kindle size would be your option. It all depends largely on what you have at your disposal including the original image.

I myself have always done a balancing act between image quality, image size, file size, resolution, and final output. Two things I have learned in my experience; one is to send the final file within the confines of the size, format, resolution, and in any other way that is recommended by the service; and two, that the more you mess with an image the more risk there is in the loss of quality, and this includes allowing the Kindle to re-size your image.(sometimes however, for many reasons, it maybe desirable that the Kindle re-sizes your images or there just maybe no other option depending on your resources, and the Kindle does do a wonderful job of conversion). The more control you can have over the original image size and resolution, and over the final image size and resolution, and in keeping the two as close to the same final size and resolution as you can; the better control you will have over your own desired final quality that will be spit out the back end. If you can obtain or have at your disposal HTML (Web Page Building) knowledge or an HTML editor, specify your image pixel size in the HTML code. This pixel size specified in the HTML should be as close if not the same as the original. More importantly, Kindle will not re-size the graphic as long as it is not bigger than the viewable area on whatever generation of Kindle you wish to target.

I would highly suggest that you create a mobi flle first and test if with kindlegen, which can be downloaded through the community at KDP and then proof your file on an actual Kindle your are trying to target or use the Kindle previewer, which is also available as a download from KDP through this community. You can then play with your graphic sizes and view their final size and quality at the final stage at the back end.

Something now that has become obvious is that digital reading devices are not just for text/words anymore.

I hope this will shed at least some light on your question or at least provide some clues for you to further research your original question. I am also sure there are many other ways of handling images for the Kindle, and that most of it I think depends on the nature of your product, how you want it presented, and the goals you have for it in the end and in the future. . . and more importantly, a book written and formatted for the utmost pleasurable reading experience on the reader's device.
