>Hi Hilmar, thanks for your reply. I did a google and found a site to convert pixel to inches. So, it isn't accurate too?

As I said, it depends on the screen size. I forgot to say that it also depends on the screen resolution.

For instance, with a 800 x 600 resolution, the same line will look bigger on a 21" screen than on a 14" screen (50% bigger, actually).

Also, on the same screen, with a higher resolution, the figure would look smaller.

So, to calculate the size of a rectangle in cm., you would need to know:

The dimensions of the rectangle in pixels

The size of your screen, width x height. Note that 14", 17", etc. is the diagonal, and that it includes the borders, not only the visible area.

The screen resolution, for instance, 800 x 600.

The last item you can easily get, in VFP, with sysmetric(). AFAIK, there is no way to automatically detect the screen size.

Once you know all this, the actual calculations are fairly simple.
