![]() If we tried to use it above that size, however, its resolution becomes lower than 72 pixels per inch and that would mean that the image started to look coarse and blocky like theright hand side of our image at the top of this article. On screen for digital design, we view images at a resolution of roughly 72 pixels per inch, so at any size up to 10 inches square, that image would look smooth and well defined. This resolution determines how clear the image will look – the higher the resolution, the clearer the image and the better it will look in brochure or catalogue designs. The image’s resolution is the number of pixels divided by the size it is being viewed at – so if the image is 720 pixels wide by 720 pixels tall, and it’s being viewed at 10 inches square, it has a resolution of 72 pixels per inch (I’m not sure why it’s measured in inches – but it’s probably a combination of the fact it originated in print before metrication and that computers were so heavily based in the US). What is ‘Resolution’?ĭigital images are made up of thousands of pixels (blocks of colour), and the number of pixels in the image will determine how high the image’s resolution is. If you want to use your digital photographs in printed brochures, no matter how beautiful the image, it is essential to make sure that the image is high enough resolution for print. ![]() If math is your nightmare, you're not alone.Tips & Tricks High-res or low-res? How to make sure your digital images are suitable for print… Posted by Colin Higton That means in order to create a 4 x 6 print on a 300 DPI printer, you want 1200 x 1800 pixels. To do that, just multiply 300 by the number of inches the print is going to be. Since we now know the printer will print at 300 dots per inch, all we need to do is figure out how many pixels to give the printer. Unless you’re printing something huge like a poster, tradeshow banner, or billboard, you’ll almost certainly be printing on a 300 DPI printer, simply because this is the resolution of most printers. Most people consider a “high resolution” share on the internet to be in the neighborhood of 1200 to 1600 pixels wide. When you’re not matching an image to a particular layout, you can be fairly loose with the size. You want the smallest file that works for your purpose. ![]() If you over-accommodate large displays with big image sizes that take a long time to load, you’ll end up serving images that slow down your site. Header images that span the entire page might be larger-in the neighborhood of 1200 pixels-which leaves it up to the browser to stretch it if the browser window is larger. On our blog, for instance, the images within the posts are around 600 pixels wide. When saving images for a website or blog, the site layout will often dictate how many pixels high and wide you need to size your image. How to optimize your image sizes for the web This complicates selecting an image size for the web. They used to be, and 72 PPI is still used as a reference for designers, but most modern PC monitors are 96 PPI. Trouble is, they aren’t-not by a long shot. Sizing for the web would be pretty easy if all screens were 72 PPI. That means a 2400 x 3000 pixel image used to create an 8 x 10 inch print would display at about 2 ¾ feet (yes, we’re talking feet here, folks, not inches) on a 72 PPI monitor. While a printer gobbles up 300 of your hard-earned pixels, your miserly monitor might only use 72. Monitors and screens use pixels much more sparingly than printers. What is the difference between print and web images? In order to print a maximum high-res image, your file needs to contain the same number of pixels per inch that your printer is going to be printing per inch. We use DPI when talking about the resolution of printers, but when we talk about monitors, we switch to PPI, or "pixels per inch." This is because monitors don't deal in dots of ink (surprise, surprise) instead, they have pixels that light up to create your image on a screen. Need quick pics for your designs? Check out our massive stock photos & videos library.Ī high resolution image is one that's at least 300 DPI, or "dots per inch." As in – the printer spits out 300 little dots of ink for every inch of your photograph. Like, what is 300 DPI and why is it considered the epitome of high resolution? Are there specific high resolution print sizes? And, what’s the difference between DPI and PPI?ĭon't worry, we're here with answers, solutions, and tips. There’s a lot to know about making a high resolution photo so that they print or display properly on a web page. Those squares are pixels.Ī poorly printed photo deems the whole thing useless, which is why high resolution images are so important. Zoom in on an image and it becomes a collection of squares. ![]()
