How to obtain the dimension size of an image in centimeters or inches

Article by Mehdi Rezaei, CSWE updated January 16, 2017


In some instances, the actual image dimension size is required in centimeters or inches instead of the number of pixels. In this example the image is going to be imported at a 1:1 scale into a SOLIDWORKS sketch so it can be used for tracing and surface modeling.

Image Properties in Windows Explorer

If you right-click an image file in Windows Explorer and select Properties, you obtain the image information with the pixel size. You can see how many pixels the image is made up of, and the image resolution. See the following image.

This does not help if we are looking for dimensions of the image in units of centimeters or inches. There are conversion factors to convert PX to CM or IN units, however, there is another easier way which is described below

Image dimension size with MS Paint

If an image is opened in Microsoft Paint, the image properties tool will reveal more information. As shown in the following screenshot, holding Ctrl key on the keyboard and pressing E (Ctrl+E) in MS Paint opens up the image properties window in which image sizes are provided in three different units: Inches, Centimeters, and Pixels. Alternatively, the image properties window can be accessed from the menu:  File > Properties.

The size of the imported image is shown in centimeters as 16.25cm x 11.38cm. In the image properties window, the colour of the image could also be set to Black and White or Colour.
