If you measured the image on screen using a ruler, then "No"
What you need to do is measure the image size in pixels. If you then divide that by the printer resolution, you will get the size of the printed image.
eg
If your image is 900 pixels by 900 pixels, and you print it with the resolution set at 300 pixels per inch (ppi or dpi) then your print will be 3 inches square. If the resolution is set to 150 ppi, it will be 6 inches square.
