Web Designing For High Resolution Retina Displays

Do you know what makes it amazing or what makes it a nightmare for designers and developers?

There are few terms related to technology that has proved to be challenges and opportunities for web designers. Device pixel, Resolution, Pixel density, High DPI, all in one means High Definition Display. In the simplest of terms Retina displays High Definition Display.

Will the iPad’s new Retina display really wreak havoc on the web?

Apple’s Retina display actually kicked off the web design challenge of creating graphics that displayed well on the much enhanced screen resolution, which doubled the pixels. The iPad have far more pixels and as a result the display will be of a much higher quality and higher definition due to higher DPI. So as this relates to Retina, it is the same principle: the same display size, only more pixels, which means a high DPI display. Because of retina displays, things are moving forward continuously and images are becoming clearer.

Most images until now have been made in 72DPI for standard displays. Now, Retina’s DPI is much greater and so these images would appear to be grainy or blurry if they are not adapted in their resolutions. As a result of this, you need to ensure that your images are optimized for high DPI devices. Retina Displays need twice the amount of pixels to display the same image as standard definition displays.

This should help you to figure out why Retina ready images are necessary and why it is important that your web developer and designer knows how to ensure that your site is optimized for them when they create your fully Responsive Website. More and more devices have high-res and if you want your product or website to look professional to users of these devices, you should put some thought into how they look. There are various ways by which you can optimize your images for such displays. A raster – or bitmap – graphic is based on a dot matrix data structure. The most common raster files are JPG, PNG and GIF and 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. You can use HTML and CSS to declare an image’s size to be half of what it actually is. With the help of jQuery, you can pin point images and half their widths and heights. It works the exact same way as the CSS example with 50% width and height declarations. Unlike raster images, SVG, or just vectors, have a great advantage for Retina Displays website design which is that they can scale up, down and sideways and still look good. The way vectors are constructed is through geometrical primitives such as lines, points, shapes, or curves which are just mathematical expression and this is what gives them the ability to scale without being distorted and looking blurry.

As you can see Retina Displays can be a nightmare to support; however, hope you chose to support it as high DPI displays are beautiful to look at and supporting Retina allows for a much better experience for the people who use these devices.
