Let your suppliers set you a picture of a ruler or reticle with fine divisions captured by their device at the top resolution in a JPEG format. From this, display the picture in your computer screen, by click the buttons below to check the size of picture:

Best Fit (Ctrl+ B)

Actual Size (Ctrl + A)

Zoom In (+)

Zoom Out (-)

First click the button of “Actual Size”, to display the true size of picture, then to measure the image size (width) of one mm division shown on screen with a rule.
