How to Size Your Images for Pressbooks
How can I ensure that the images in my book are print- and ebook-ready?
What size should my images be before I upload them into Pressbooks?
If you’re only making an ebook or a webbook, anything from 300 x 300 pixels and up should work fine; if you’re printing your book, you’ll need to be more careful, and keep in mind the 2MB per image upload limit as well as your overall storage limit.
But the media editor lets me resize images–why can’t I just do that?
The Pressbooks media editor can only shrink your images, not enlarge them; it can’t add more detail to them. The best way to resize your images is to start with the original.
Should I add my images to my chapters at full, large or medium size if I’m doing a print book?
To ensure the highest possible image resolution for print use, images should always be inserted at full size; smaller size options will compress the image, resulting in it not being exported at the highest possible resolution.
How do I control the exact location of an image on the page–for instance, in a photo spread or photo book?
Photo books, children’s books, and book genres that require a lot of image placement are not suitable for Pressbooks, which is an image-heavy tool.
How do I upload just one image for both ebook and print? I need it to be high enough quality for print, but also not make my file so big it incurs ebook digital delivery fees.
Use the “Reduce image size and quality” option under “Ebook Options” or “Image Size and Quality” to compress your images for ebook export. Your print image sizes will remain the same, but the file size will be reduced.
If I’m just doing an ebook, what size (resolution and dimensions) should my images be?
Image quality is less of a concern when working on an ebook than it is when working on a print publication, but it still pays to be cautious with your uploads.
I put in a 300 dpi image but it didn’t stay that way. What gives?
If your image is being marked as less than 300 dpi, double-check that it’s actually large enough, and that the size at which it was inserted matches the size of the page it’s on when viewed in full-resolution.
What is a good pixel size for printing?
The higher the number of pixels per inch, the finer the detail in the print will be and the sharper it will appear; 180 ppi is probably the minimum value for reasonable print quality; 240 ppi is better; and 300 ppi is best.
What is the best size resolution for printing?
So, how high of a resolution value do you need for professional quality printing? The industry standard is 300 pixels per inch, which squeezes the pixels in close enough together to keep everything looking sharp; in fact, 300 is usually a bit more than you need.
What resolution is used for printing?
The majority of digital and offset printing presses print at a resolution of 300 DPI (dots per inch), which is considered high resolution and the minimum DPI for quality printed output. Because high resolution artwork files are created with graphics software, they are created in digital (pixel) form.
What size is 1920×1080 pixels in inches?
This image is 5.75 inches wide on a 23-inch 1920×1080 pixel LCD screen (110% text size), 5.6 inches wide on a 19-inch 1280×960 pixel CRT screen, 6.0 inches wide on a 17-inch 1024×768 pixel CRT monitor, and 3 inches wide on an iPhone 5S (held horizontally).
How does pixel size affect image quality?
Higher resolutions mean more pixels per inch (PPI), resulting in more pixel information and a high-quality, crisp image. Images with lower resolutions have fewer pixels, and if those few pixels are too large (as in the image below), they can become visible.
Is 600 dpi Good for printing?
High resolutions above 600 DPI are better suited for professional archive work due to the longer scan time and larger storage requirements.
Is 1920×1080 good resolution?
1920×1080 (also known as 1080p) is the current standard screen resolution for modern computing and the most popular resolution for gamers; if you’re buying a new screen, anything with a resolution lower than 1080p is doing yourself a disservice.
Is 400 dpi Good for printing?
Other valid opinions exist, not about the detail, but about the upsampling: you may prefer the 400 dpi image to the 2X resampled 200 dpi image for reasons other than detail; scanning color prints above 300 dpi won’t help much, but it won’t hurt either.
Is 96 dpi OK for printing?
If we indicate that some of your images have low resolution, they may not look bad on your monitor but will most likely print blurry or jagged.
