Thank you, Prasad! The technical explanation is still a but too much for my level, but I hope to soon understand. I need to read more about Copperplate and calligraphy. The thread is helpful. Glad to know I'm not the only one wondering about this when they first started out. 
Sorry for the newbie question but do you have any idea where I could find the proper exemplars/tutorials for studying formal Copperplate? Are the ones posted in the pointed pen nirvana section by Erica considered formal?
Most welcome.

Erica's tutorials are perfect to understand the concepts of pointed pen, pressure and formation of letters. I found it to be the perfect place to start. Dr.Vitolo had great resources if you want to study formal copperplate. He gets into the technicality of each letter and formation.
He has a great interactive book with videos for the iPad. you can download it for free. The link is about halfway down the page at
http://zanerian.comIf you don't have an iPad you can see his videos at the IAMPETH site (Video sections) Pages 1 and 2 have the capitals and 3 onwards is the minuscules.
For slants, height and widths you can try the following:
Use guidelines from this site.
http://shipbrook.net/guidelines/This allows you to set the size of the x height.
5 per inch is about 5mm x height.(The calculation is 24.5/no. per inch = x height in mm) You can choose "custom" to make even 1 per inch.
You can also set the distance between the slants. To get good spacing, you should make the slant distance about half the x height.
So you can make the selections like below:
Ascenders - 2 x
Space - no overlap
Angled - 55 degree
Every - (choose mm ) and mention a figure that is half the x height.
5 lines per inch is about 5mm x height. So the "Every" option will be 3 mm
3 lines is about 8mm - Every option 4 mm
and 2 lines is about 13 mm - every option 6 mm
This is helpful in the forming of width of the letters and spacing.
The width of a letter should be half the height and the space between alphabets should be half height in most cases.
Next is the option to vary the darkness of the guides.
If you set it to 25% black or non-photo blue and then print on your practice paper, you can practice directly on the guidelines itself.
Set it to 100% and you can use it behind your paper.
This helped me a LOT in understanding the spacing and width to height relations of the alphabet.
There aren't many exemplars that show the slant lines drawn in and give an idea of spacing. But in a thread about quills Brush My Fennac had a post of writing samples. This was the only place I could see the slants drawn in to form each letter. Picture attached below.
Sorry for the tediously long post
But I have been through exactly what you have and the people on this forum gave me perfect guidance to move ahead in the Proper manner.
