Size is the dimension of a printed piece, generally measured in inches or millimeters, so the printed part fits into the page.
Several methods can be used to work out the dimensions of a printing job. For example, they can take a standard paper-size approach. They are generally called letter (8.5” x 11”), legal (8.5” x 14”), and tabloid (11” x 17”). The dimensions are always considered when printing flyers, brochures, or newsletters.
The other method for calculating the size is by use of custom sizes. This method is most common when the piece must fit in the envelope or space. Accurate measurements of all custom sizes are required to ensure accurate printing of your work.
Size is also determined by page space available, and most often, this is the case when printing documents like reports or books; in such cases, printers change the default printer setting for documents to fit perfectly on that given page.
The dimensions are an issue to be taken seriously as far as printing jobs are concerned. A few measures will be taken to ensure that the measurements for a printing job are appropriate and your work is printed as desired without mistakes.
Size is of utmost importance in printing as it can directly affect the quality and look of the final product. The image should be neither too small to the extent that you might find reading it complex, nor too large that it would look empty. Furthermore, the size would depend on the intended project and aesthetic preferences.
