Max Resolution

Guiltyr1 · 11-13-2015, 07:37 PM

Just out of curiosity, I bought the new Paperwhite 300ppi. Does anybody know the max size/resolution I can use for book covers? I believe in Calibre, I have the default book covers set to 450x 680 but I am not sure if I could be using a higher resolution????

The screen resolution is 1430 x 1080. You can use Google images to find high resolution covers.

I've seen (and used) resolutions as high as 2500 pixels on the long side, but as it makes the book load slower, display slower in calibre, and use more space, I've since decided to keep the resolution at 1000 to 1200 pixels on the long side. If a cover I find falls in between that, I don't resize it. If it's bigger, I resize to 1000 pixels on the long side.

I know, at some point resolutions will become so high that the cover will be blurry (2000 pixels on the long side would be the highest not-too-blurry resolution in my case), but no matter what resolution you choose, you'll eventually reach that point.

The only thing for which I use as a high a resolution I can find is maps.

I use 1200 to 1500 on the long side. A lot of covers from Amazon are 1500 and that works well.
