isoman... each step will be 8 13/16 inches high, and 10 inches "deep"...cut the stringer so that the bottom step cut is 7 5/16 inches above the floor to allow for the thickness of the board you are going to add for that bottom step platform...this will bring the platform for the bottom step to the correct height of 8 13/16 above the floor... as you cut the rest of them 8 13/16 high, the thickness of the preceeding platform will take up its own space, making the tops of each step correct in its height above the one below...8 13/16 inches... you will have 9 steps, plus the top floor landing, which will be a total of 10 steps... if you go according to this instruction, the top of your stringer will be correct in relation to the top landing you are working toward, and when you add the platform to this 9th step, you will find the height to the top floor to be correct for the 10th step, which is already there... you will need 12 ft. 2x12's to cut your stringers out of...your stringers need to be cut for 9 steps, but your facing boards need to cover 10, so you will probably need 14 ftr's for them...it sounds funny, but it is accurate... i suggest you built one stringer first and make certain everything is as you wish for it to be...you will probably need to tweak a little...nothing ever goes exactly as you want the first time, and this is a difficult thing...when you get this first one correct, you will use it as a template to mark the others... assuming this stairway is inside and going to be covered with carpet, i suggest yellow pine with grain running side to side, not face to face...if your grain runs as i suggest here, your stringers will be a good deal stronger, less apt to warp, and not nearly as likely to split.... if you want bare wood, then you may still wish to use yellow pine and stain it, or cover it with polyeurethane, or both...or you may use any of several "decorative", expensive woods... at any rate, i suggest you stay away from spruce...it is light weight, rather weak, and prone to failure with the cuts you will be making... if you are determined to use only 8 steps plus the top landing, your steps are going to be 11 inches in height...too high for the elderly and the very young...i suggest you go by the above...also a surface less than 10 inches wide is too narrow, and that makes it dangerous... but, if you are going to go with only 8 steps, plus the top landing, your measurements will be 11h x 11.25d, with 1 1/2 taken off the bottom one for the first platform... depending on how wide this stairway is going to be, and how you want it to ultimately look, i suggest 3 stringers and a "facing" board on the outside(s)...I.E., if the stairs are attached to the wall you will only need one "facing" plank...if they are free standing, i suggest one on each side... the measurements i have given you add up to 88.125 inches in height...1/8 inch over h/d 88x90 is insignificant... good luck... donald
