A major factor while building deck railings is to design it based on your state's building codes. They usually limit openings between balusters to 4 inches and a height of minimum 36″.

Instructions for Building Deck Railings

The first step involves choosing from the multiple deck railing patterns available, to find a suitable deck plan and design, that complements your deck. Choose a deck railing design and material of the deck baluster that you want to use.
Figure out the amount of railings needed to cover the deck completely and ensure that the height and width conforms to the area's building code requirements. This should be followed by planning out the location for the fence posts.
Use a four-sided figure, to mark out the position of each post, beside the joist header and the outer joists. Now cut all the parts to length by using a power miter. Clamp all the pieces together and transfer their measurements to several pieces at once, for speed and accuracy.
Make the upper deck railings by sizing up the pieces of wood into 2" x 6" sizes, with a crown curving upward. Attach the railings to the deck temporarily, with 3" small screws or ACQ finishing nails.
If you wish to install 4 x 4 posts at the bottom or the top of the steps, then the posts should be sunk at least 3 feet deep into the ground and backfilled to remain stable.
Then, mark the position of the balusters using a framing square for accurate measurements. Place them at least 5 inches away and attach the balusters to the corners of the upper deck railing. Use deck screws for this purpose.
Now, permanently attach the upper deck railings by screwing the bottoms to elevate it into place. Once you are finished, make sure that the tops of the railings are leveled.
Once the upper level is aligned, clamp it to the support posts, and then attach it using wood screws. Now add the rest of the balusters in place and fasten them to the posts, by piloting a diagonal hole and using a 3" deck screw.
Finish off by crafting a top rail, making cuts on two 2" x 6"s, by using the miter saw to form two 45-degree mitered cuts. Now drill in the screws horizontally through the miter joint, to set the top rail securely in place. Now stain the railings to match your deck.
While incorporating your deck railing ideas and building a deck railing, it is important to keep some safety tips in mind. These include making sure that the steps are already built, making the deck easily accessible. Also to avoid people from absentmindedly walking off the edge of the deck, put up a temporary safety barrier of 2" × 4" of colored nylon rope.
