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.
OSHA requirements for stairs used during construction apply to any stairs, fixed or temporary, that construction employees may use. These stairs must have a 22-inch wide and 30-inch deep landing for every 12 feet of vertical rise and be set at an angle between 30 and 50 degrees from the horizontal. Variations in stair height cannot exceed 1/4 inch.
