As the number of prints increases, most people begin by specifying the final size, which they, like their print, are without actually referring to the original image. They usually do this because they want to place a frame or a specific wall area.
Unfortunately, images have a fixed ratio (length to width), so when you enlarge or reduce an image, you cannot select the desired size: it must relate to the original ratio of the image. Otherwise, the image will look stretched or compressed after it is printed.
If you already have an idea for the final print size, Clockwork has developed a simple calculator that allows you to develop new sizes. The calculator gives you two sizes that ensure that the enlarged image will not be distorted. All you need to do is enter the original image size into the calculator, as well as the desired size that you want your image to be. Then the calculator will provide you with two options that support the perspective of the original image and adjust it as close as possible to the desired size.
This is a very simple tool that saves you a lot of trouble when trying to increase your prints. Below we give an example:
James has a photo of the A5, which he wants to enlarge to 500x700 mm to fit the frame.
The size of the original - 149x210 mm. When you connect these values to the calculator, we get the following:
Option 1. Width: 500.00 - Height: 704.70 - Scale Percentage: 336%
Option 2. Width: 532.14 - Height: 750.00 - Scale Percentage: 336%
The calculator returns two print sizes: one that is inside your desired size, and one that is slightly larger than your desired size. In this case, since this is a frame, you should choose a smaller size of 500x704 mm so that your printed poster matches the frame.
For a more advanced user, the calculator also gives you an enlargement or reduction ratio, which makes it very easy to find out the percentage value for enlarging or reducing an image when it is printed.
