The point size is only one of several considerations you need to make. Any ITC font has a large x-height, so it looks larger. Script fonts in 10 point can look smaller than 4 point ITC Galliard, because they have long ascenders and descenders, and a small body (x-height).

As important for readablity is the length of the line (measure). It should be between 60 and 90 characters to a line. If you get much higher than this, and it will be hard to read the line without dragging your finger along it (like you did in grade four). Increased leading (space between lines) can help, but it is better to use a larger font.

I disagree with about half of that article, probably because it was talking about brochures, and you are doing documentation. That is like studying up on the digestive system when you have to do some brain surgery.

As Ramon says, there is a lot to choosing a font. We will help if you want. Others have posted links to pdfs of their plans, and we have critiqued them and offered suggestions.
