For purely virtual images, we have a calculator/converter that allows you to convert between different virtual sizes: the px to em calculator. However, when we're talking about a digital image in a computer, PPI cannot be computed since the digital image varies in size depending on the level of zoom, the size of the screen, etc. For example, a screen or a printed picture has a fixed physical size, so it makes sense to calculate how many pixels per inch there are in such an object. It is important to note that for calculating PPI we need something that has a physical size, not a virtual file.
Also worth mentioning is the fact that our pixel density calculator assumes square pixels. There are other measurements of pixels density, such as pixel per square inch, that involve calculating the area of a rectangle that is the screen. This measurement is based on the fact that screens and images, despite being 2D, have generally the same density along any of the two main axes. The density is measured as the number of pixels that fit on a 1-inch line, hence the name. The technical PPI definition is pixels per inch, and it represents a measurement of the pixel density of a screen or a digital image.

Visit for all of your projector and projector screen needs for all aspect ratios. To achieve a perfect aspect ratio, you must employ the use of an aspect ratio calculator. While aspect ratios are measurements of the height and width, they are often reduced to the smallest usable ratio in order to fit perfectly in every medium.
Read a review about us from .Īspect ratios are largely defined by numbers, as in a mathematical ratio that clearly defines how many inches high and how many inches wide your video, image and design projects should be. You have to understand what aspect ratios are in order to easily move designs, images and compress digital video files/content from one medium to another without making any error in your calculations.įor the record, the proportional relationship between the height and width of a rectangle is what is aptly referred to as an aspect ratio.Īspect ratio calculations matter a lot depending on whether it is an image, design project or a digital video you are working with.
