There are several different processes for interpolation, but they all run the risk of producing artifacts or distortions in your image. Interpolation uses software to determine how many new pixels to add and what color those new pixels should be. Interpolation is how photo editing software, like Photoshop, increases the size of a photo beyond what’s included in the pixels that came with the image file. I’ve put together a quick guide and how you can increase image resolution in order to get a good print. You’re going to need a bigger image with a higher resolution if you want to get a good quality print. That same 600×400 size is going to be way too small to get a good quality print. This resolution is more than enough to look great on tablets and laptops and still load fast even on a slow data connection. This is because websites typically use images that are roughly 600 by 400 pixels. If you’ve ever tried to right-click and download a picture from a website and then print it, you’ve probably experienced a lot of blocky, low quality prints. The lower your image resolution goes, the smaller your print sizes need to be in order to retain quality. Enlarging images is easier when you have a big file size and plenty of pixels to work with. Resolution, print size, and the quality of your prints are all directly linked together. Resolution is easy to measure in terms of pixels per inch, but hard to measure in terms of subjective standards. Megapixels aren’t everything when it comes to image quality. It’s also easier to resize images if they have more pixels to work with. This allows you to produce prints that are larger and have a higher DPI. Pictures with a higher megapixel count will hold more information and have a larger image size. The Sony a7 III has a 24.2 megapixel sensor while the new Apple iPhone 14 Pro Max has a 48 megapixel sensor. Your camera’s sensor was built to pick up a certain amount of megapixels. High megapixel counts allow for bigger prints with higher DPI, making it easier to resize image for printing without compromising on quality. A 24 megapixel image has a pixel height and pixel width of 4,000 x 6,000. You’re probably used to hearing resolution talked about in terms of pixels and megapixels. There’s a lot of marketing hype around big pixel dimensions, but I’m going to demystify this subject so that you can always print high quality photos. There’s a lot of misconceptions about image resolution, especially when one wants to resize image for printing. Now that you’ve had a crash course on what influences print size, it’s time to talk resolution and image size. If your printer can’t handle 300 DPI, and if you don’t resize image for printing correctly, you might be restricted to smaller print sizes. Printer power is also going to impact the size of your print images. The 3×2 aspect ratio is one of the most popular for photography, but the right aspect ratio for your print will depend on your artistic goals and how you resize image for printing. If you have a 300 DPI image file and you properly resize image for printing, you’ll get high-quality prints in just about any regular size.Īspect ratio is the next thing to unpack when it comes to how print size works.Īn aspect ratio is the measurement of the horizontal and vertical lengths of an image. The global standard for printer resolution is 300 DPI. Printers, on the other hand, use a similar measurement called dots per inch. Pixels per inch, or PPI, only measures the screen resolution of your images. Every digital screen measures its resolution using either pixels per inch or pixels per centimeter depending on where in the world you live. Similarly, you could just hit print and hope for the best or you can master a few details about resize image for printing that will elevate your photo prints to a new level. However, you can quickly level up your photography game by mastering a few basics. It’s really easy to get started with the basics of photography by picking up a point-and-click camera or just shooting on your smartphone. Printing off your photographs is a lot like photography itself.
