Woodworkbykirk is right. I would go with the 11.25'' treads if you have the horizontal space, and a landing would be ideal. Australian code requires a maximum of 18 straight risers before you need a landing at least 4' in length, but I consider this extreme if you have room for an intermediate landing.
A stair 12 feet high requires a landing to break up the span. The addition of a landing will use up allot more space and therefore these types of stairs are seldom used in residential construction. You will see these more frequently in large commercial buildings. Straight Stair with central landing.
