I have to do a professional business letter to a bank from me a customer there. What i need help in is the letter measurements without a heading. I'm not sure what they are. What i think they are is for the alignment:

Left side 1"
Top 2" Please help me in
Right 1 1/2" the correct
Bottom ? measurements.

Even though i don't need a page header what are the measurements there.

Here is a really good webpage that has a complete explanation:
