Here is some info for you
Not sure if you want indoors or outdoors:
Which ever your project is be sure it is up to code.
You can buy and the rail from a DIY store fix to the wall with glue and plugs or you can use special brackets and a rail . Measure up the wall the distance you wish the rail to be installed. Mark the wall all the way up and draw a line to follow. Best wishes.

Hi! maybe this will help
Indoor or out?
If outdoor, you can attach to the stairs. We did a 4x4 post at the bottom, another at the top and a 2x4 in the center if you feel it's needed. Cut the top off at an angle to match the stair angle. Four 1x6 boards: #1-across the top for the rail, #2-along the top, #3-along the bottom, #4-mid way between #2 & #3. It gives a farmhouse fence style.
If you don't want to have that feel, you can use spindles.
You can attach to the wall unless they are free standing. If they are, then you can affix supports to the stairs as you would outdoor stairs and build the rails that way.

Hello. Most hardware stores sell the hardware and wood needed for conventional handrails.
Unless you want to more creative idea some people will use an outdoor branch, rope or we have even used an oar....in our house for a basement stair handrail.

Hi Doris: You can buy the railing at most home improvement stores, in the length you need, along with the brackets that hold them, which should be screwed to the studs. I think 3 should be sufficient. Some cities require a turn in at the ends of the hand rails in order to keep things from getting caught and causing a fall. Those are just pieces of railing cut at an angle on one end and secured to the wall. I'm just guessing that you, or someone in your home, are having trouble climbing stairs. My mom had the same problem. What I did for her, and she lovedit, was to put a piece of railing, about 18" long, at both ends of the railing, going vertically. It was so easy for her to grab when she stumbled, which was often. Here are a couple sites that might help:
Are the stairs in the open or is there a wall next to it? If you have a wall, there are brackets and handrail that fasten to the wall. Ensure the brackets go into a stud or other structural component of the wall.
Unless you ate good at woodwork and have the tools, it is usually less expensive to buy a section of railing. You can find them online and at local building supplies. Check online or call ahead to make sure it's in stock. I like to check online for Home Depot or Lowe's, because not only do I know what is in stock, but it will tell you which aisle and bin for finding things. Good luck and stay safe!
