Porch Steps Tread Depth?

I have a front porch 24 1/2 inches above the concrete walkway. There are presently 2 steps, each slightly more than 8 inches high. I want to build new concrete steps changing from two steps to three. Each step will be about 6 1/8 inches high. The width will be 4 feet.

My question is: What is an appropriate tread depth for a step which is 6 1/8 inches high? I was thinking about 15 inches. Is this too deep?

Steps should feel COMFORTABLE. We have all seen steps with different riser height and tread depth, and although there are some basic rules it still boils down to feeling comfortable. Steps with short riser height usally means a SLOWER pace. A lot of state and governemt building require a lot of steps to reach the entry, and slowing the pace makes the process less excerting. When a short riser height is used then a long tread in normally present.

I am no expert, but a 15" tread for only three steps seems a bit deep. I would think more like 9 - 12 inches would be about right, but you need to consider what is best for your layout.

I wish you well, and have fun figuring it out, FUN IS GOOD.

15" would be quite wide and would make most people feel like they need to put both feet on the step before taking another step up. (Most NBA players would probably love them, however.)

Steps inside homes usually have 2x12 treads which are 11 1/4", and they are usually quite comfortable. IMO, you'd want your tread to be closer to 12", if possible. The angle of the steps is the main issue. This is usually determined in a couple ways.

riser + tread = 17 1/2" <--- using this formula you'd subtract 6 1/8 from 17 1/2, making for a tread that is roughly 11 3/8.

or

riser x tread = 75 <--- using this formula you'd divide 75 by 6 1/8, making for a tread that is roughly 12 1/4".

or

2 risers + 1 tread = 24" <--- using this formula, you'd add 6 1/8 + 6 1/8, making the tread roughly 11 3/4.

All these formulas are approximate, and as long as you don't stray too far from the formula, it will result in an incline that is between 33 and 37 degrees, which is a comfortable grade.

Wirepuller 38, THANKS for your thanks I love this site, but just don't understand why folks ask for help and then it seems like they just DISAPPEAR?

Often someone will write the sponsor, NEED MORE INFO, and then nothing happens.

I still love them, but wonder.

Gratitude

Dale,

I totally agree with you. Visualizing the situation is often difficult without more info. I would like to see more photos and diagrams used.

I also like to know if I have helped someone.

Thanks, again. Look forward to reading your posts.

Ken

Steps

Finished placing the concrete for the steps today. Mixed 21 wheelbarrow loads. Will have pictures after the new posts and porch railings are done. Thanks again.
