Your screen resolution determines how large the image appears to be. Images are of a fixed pixel size when they appear on your monitor. To find out what your screen resolution is, choose Start > Control Panel > Display > Settings and look at the screen resolution (Windows) or System Preferences > Displays and look in the resolution section (Mac OS). For example, large monitors typically display higher resolutions than small monitors because they have more pixels.

There are several different screen resolutions you can use, and the physical size of the monitor screen usually determines the resolutions available. For example, a monitor with a screen resolution of 640x480 pixels will display 640 pixels for the width and 480 pixels for the height. The screen resolution of your monitor is the number of pixels that your monitor can display. If you understand these differences, then you can develop a better understanding of which settings to change when you resize an image. The size of an image when you view it on the screen is different from the size of an image when you print it. If you resize and crop images without being aware of the concepts involved, then you may see unexpected results. These concepts affect how the crop tool options operate as well. To get the best result when you resize images, you should understand the concepts behind and the results of each method of resizing. Each way to resize an image has advantages and drawbacks. You can resize your images in several ways using Adobe Photoshop and Adobe Photoshop Elements.

Unfortunately, resampling in this manner often leads to undesirable effects. You can try to regain lost detail with PhotoshopвЂ™s Unsharp Mask filter, though results might be mixed. However, resampling often leads to undesirable effects such as poor image quality. You can play around with each of these options to see which produces the best results for your image.

Adds pixels according to the average color values of surrounding pixels.s.

Replicates image pixels but is less precise than other methods.

Enlarges your image with an automatic emphasis on smoothness.

Adds a noise reduction slider so you can smooth the image when you enlarge it.

Photoshop automatically decides which option is best based on the type of document you have and whether youвЂ™re scaling the size up or down.

Document dimension: The physical size of the printed piece.

ThatвЂ™s because there arenвЂ™t enough pixels per inch to maintain a sharp image at large document dimensions. Low resolution, or low-res, images will appear pixelated and blurred after printing вЂ“ even though they might look perfect on your computer screen. TheyвЂ™re perfect for the web because they feature smaller file sizes that can load quickly online, but they do not translate well to print. What about the best resolution for pictures online? Web images are commonly created in 72 or 96 PPI, which are considered to be low resolutions. (If youвЂ™re working with photography, youвЂ™re probably working with high-resolution JPEGs, which can be printed as stand-alone photos or incorporated into your brochure printing and other projects). These are considered to be high resolution, or high-res, images. What resolution should photos be for printing? What should DPI (or PPI) be for printing high-quality artwork? In many cases, the best resolution for printing is 300 PPI.ДЄt 300 pixels per inch (which roughly translates to 300 DPI, or dots per inch, on a printing press), an image will appear sharp and crisp.
