So, once again, if you have an image which is 600px by 800px but is supposed to be displayed at 300px by 400px try defining its width and height like this: However, you can also utilize CSS to define the image’s size. Through HTML you can specify the image to be half that size.Īs you can see, this is a very simple and straightforward concept. You need to have this image actually be 600px tall and 800px wide. So, if you have an image that is supposed to be 300px wide by 400px tall. You can use HTML and CSS to declare an image’s size to be half of what it actually is. Here are three common ways of going about this. So what can you do about this? First, you will need to have an image that is double in size and you’ll half it for the displayed size – to the original intended size – with code.
Even though the image is displayed in the same size, it is actually being stretched which causes the image to look blurry. In order to accommodate for the change, Retina display multiplies one bitmap pixel by four. On Retina Displays, a raster image’s 1 bitmap pixel is equivalent to 4 device pixels. In standard resolution, a raster image’s 1 bitmap pixel is equivalent to 1 device pixel. Ah, but they can scale down which is how you achieve great Retina ready raster images. The one key thing to note about raster images is that they are resolution dependent, meaning that they cannot scale up without losing the display quality. Raster images are characterized by being rendered pixel by pixel where each pixel individually corresponds to a particular hue, saturation, brightness, opacity and position within the whole image. The most common raster files are JPG, PNG and GIF. Raster imagesĪ raster – or bitmap – graphic is based on a dot matrix data structure which means it is based on a rectangular grid of pixels.

Now that you understand why Retina ready images are necessary it is time to learn the various way on how to optimize your images for such displays. Therefore, even though iPad 2 and iPad 3 have the same physical screen size, iPad 2 has a resolution of 1024px by 768px, while iPad 3 has a resolution of 2048px by 1536px. Retina Displays require double the pixels to display the same image as standard definition displays. Let’s summarize: The smaller the pixels and the closer they are together makes for a much better, shaper and higher quality images. With Postcards you can create and edit email templates online without any coding skills! Includes more than 100 components to help you create custom emails templates faster than ever before. This is why you need to optimize your images for high DPI devices. However, Retina’s DPI is much greater and those images will look blurry if they are not adapted in their resolutions. Most images were and still are made in 72DPI for standard displays. So in terms of Retina, this is the same exact concept: same display size but more pixels, which means a high DPI display. The iPad will have many more pixels jammed within the space and because of this the display will be higher quality and of higher definition thanks to it having a higher DPI. So with that said, you can have an iPad and an older desktop monitor with the same physical size but different pixel densities.
