What should resolution be

Images on screen are made of colored squares called pixels. Ideal screen image resolution detail an image holds is 72 pixels per inch. If an image is less than 72ppi, it will appear fuzzy what we call pixelated. On the high resolution screens that have become popular in recent years, 72ppi might still look pixilated. Whenever possible, our graphic designers recommend you use.

Screen resolution is measured in pixels per inch PPI. A pixel is a tiny square of color. A monitor uses tiny pixels to assemble text and images on screen. The optimal resolution for images on screen is 72 DPI. So, DPI means that a printer will output tiny dots of ink to fill every inch of the print.

This means that that images should be a minimum of dpi x dpi or 90, dots per square inch to produce a high resolution print. How the two work together. Documents begin on screen and either stay on screen, or they are printed. If the document will stay on the screen like a website , you just need to worry about screen resolution, so your images should be 72 PPI. This sounds more complicated than it really is. The eye can start to see the individual pixels, and the edges become very jagged.

With printed images, we must pay close attention to resolution to ensure we get a high-quality print. For web images, we must focus on the pixel dimensions. Look at the two images below - one is ppi and the other is 72ppi. Pixel Dimensions x ; Resolution ppi. Pixel Dimensions x ; Resolution 72ppi.

Both of these images display at the exact same size even though their resolution varies. This is because the pixel dimensions are what really matter when working with web images.

Notice that the pixel dimensions of each image are the same and therefore both images will display at the same size even though they have differing resolutions. University of Michigan Library Research Guides.

Physical vs Memory Size Physical Size The physical size of an image refers to the dimensions in which it would print ex: 8. Memory Size The memory size is how much memory an image file takes up on a hard drive.
