Deck Stairs // Varying riser heights

Just rebuilt my deck and stairs, but my riser heights vary too much. From top to bottom here are the riser heights:

6-1/8
6-1/2
6-1/2
6-1/2
6-1/2
7

Picture attached. Any advice is greatly appreciated.

Dave

Code reads risers shall be no higher than 7 3/4" with 3/8" variance from step to step. You are OK except at the bottom where you are 1/8" off. In addition, all riser spaces taller than 4" must have riser material of nominal 1" Material. No open spaces.

Man, this is the easiest question of the day. You need to cut 1/2" off the bottom of the stair jack (where it rests on the deck) so that the top step is 6 5/8" and the bottom step is 6 1/2". Then only one step will have an 1/8" of variation. Lay a strip of 1/2" plywood on the deck landing at the bottom of the stairs next to the stair jack and mark it with your pencil. Then cut on that line.

I'm guessing you will have figured this out on your own by the time you read this.

Either that or we have misunderstood your problem. As Larry mentioned, the total height of each step must be close to being the same... from the surface of each tread or landing to the surface of the next tread or landing.

thanks all. What if I install an outdoor welcome may that's 1/2" thick at the bottom of the stairs and bolt it in?
