Hopefully other users can see the simple calculation to get some rules of thumb on the size comparison of points to pixels.

Trust me I had the same mindset problem of points and pixels. It took awhile to get used to the difference of conversion. Being a fellow Ontarian, do you remember when Canada changed from Imperial units to Metric. At that time I had to work with both. Ended becoming a engineer. Boy were those conversions fun, but eventually came around to a Metric mind.
