EXISTING ARTWORK
Estimate print size from an existing pixel grid
Calculate the physical dimensions represented by a source at a chosen PPI without treating the result as a quality guarantee.
You have a finished 5000 by 5400 image and need to understand what physical area that grid represents. In pixels-to-physical-size mode, RSPrintMetric divides each edge by your chosen PPI. This gives a size relationship, while the artwork detail and intended production method still need separate review.
Use actual saved pixel dimensions
Read the width and height from the saved source file rather than from a browser preview box. The preview can be scaled for display without changing the grid. Enter 5000 and 5400 as pixels, choose the physical output unit and specify the density for the example. Keep the original file so that the calculation can be traced to its real dimensions.
Calculate both edges at the chosen density
At 300 PPI, 5000 divided by 300 is about 16.6667 inches, while 5400 divided by 300 is 18 inches. In centimeters, multiply those values by 2.54 to obtain about 42.3333 by 45.72 centimeters. If you choose 250 PPI instead, the same grid represents 20 by 21.6 inches. The pixel count did not change; only its intended physical mapping changed.
Separate canvas size from useful detail
The full grid may contain transparent padding, and the visible design may occupy a smaller region. A blurry source can also have large dimensions after enlargement. The physical calculation does not evaluate those issues. Inspect lettering and contours and estimate the visible design dimensions before interpreting the entire canvas width as the width of detailed printable artwork.
Check the receiving workflow assumptions
Confirm the required physical area, pixel dimensions and density with the current job instructions. Some workflows ask for exact pixels, while others use a physical placement size and resolution metadata. RSPrintMetric does not write that metadata or alter the file. Use its result to plan and cross-check the job, then verify the actual asset and destination preview with the chosen assumptions documented.
