Stair Risers: Too Big or Too Small?

I am rebuilding a small set of steps leading to a sunken living room. The total rise is about 26", meaning I can either use two risers of about 8.67" or three risers of 6.5". We currently have two, and while they do feel a bit high, we are probably just used to it at this point.

Any reason too big or too small would be better? Also, would the tread size change based on the riser size?

I believe code limits riser height to 7 3/4. When you get old you will appreciate 6.5.

Good practice on stair tread/risers is to adhere to an 18" united inch measurement. Total rise and run should be about 18". If you decrease one, you should increase the other. Decreasing your riser to 6.5" would make your tread 12" or so. However, with only 2 or 3 steps, making them identical is the key to prevent tripping.

Thanks for the advice. I guess I might try and rough together some to try walking on both. We have gotten used to the higher risers, but maybe the lower would be more comfortable.

If you ever go to sell the ones that have a riser that is too high might become an issue.

I'd go for three stairs to stay under an 8" rise.
