How to Calculate Resolution or Pixels to Percentages in an Image (Example)


The quality of an image is measured by light, color, and compression. Therefore, we can talk about the resolutions or pixels that is the smallest and most important element in the images. Therefore, it is good that you know how to calculate resolutions or pixels to percentages in an image.

Knowing that the higher resolution, you will get an image with better visual quality and more details, will help you understand that the resolutions of the images will depend on the number of pixels they contain per inch.

Therefore, if you want the image to have more information, you must have more pixels per inch. But when an image is made, the most important thing is the final result that we will obtain, either in digital or in print.

However, don’t worry, in this post we will show you how calculate resolution or pixels to percentages and to be able to obtain the expected result in the end.

Resolutions in images

The resolution of an image is what will report the number of pixels and it is also in charge of classifying most of the devices that are related to digital images; such as printers, television or computer screen, digital camera, scanners, among others.

It is important to know that the resolution also it will depend on the device you are usingIn this regard, some devices can generate images in 1080p or 1080i.

If we refer to the camera, the number of pixels that a photograph has will depend on the configuration and how many pixels you are using the CCD sensor of that camera when taking the picture. When we are zooming in on the image, we can see that pictures are being formed that only have a single color; this indicates that it can be divided and means that the resolution of that image is up to there. However with Photoshop it is possible to recover the pixels of a depixelated image.

When printing, the number of ink drops accepted in a square inch is very high; For example, if you are going to print an image and it does not have a good resolution, the image will be blurred; that is why modern printers today have a resolution of 600 or more DPI (dots per inch), that means that the ink droplets that you can put is 600 droplets in color inks, in a row and in linear inch.

Therefore, if you have a photograph whose size is 3000 x 2000 pixels; the width of this will only be on the paper in thirteen centimeters, this because the resolution is higher. In other words, the highest quality is allowed by the paper, since its resolution is much higher than the screen. In summary, we can say that the higher the resolution of the image, printing it will improve its quality. it is important to add that

Calculate resolution or pixels to percentages in an image

To calculate the percentages of the images you will be able to obtain three results that are the same size, enlarge or reduce it. If it is a digitized image or if the image is printed, the final size should be approximately 5mm, larger than the size of the original. Therefore, to calculate the size in percentage and not lose the resolution, you can do it in two ways: the final size and the original size.

It starts from the two-dimensional position width by height and the data will always be placed by the size in that same order. This percentage is named: reproduction factor and you can do it by applying a very simple formula.

What is it: (reproduction factor = dimension of reproduction or model) / (dimension of origin) and later (reproduction percentage = reproduction factor) X 100; we change the factor for its equality.

Then you must place. Reproduction percentage = Dimension of the reproduction or model / dimension of the original X 100.% = Dr / Do x 100 (You must write it in fractions). At all times in the original dimension of the data will be taken as correspondence to width or height, whatever the case. But, if one of the two data does not manage to reach the size, you will have to choose the largest percentage in enlargement and the smallest percentage in reduction.
