Count how many posts you will need. Your deck might already exist supported past posts, specially if it is covered. If not, yous'll demand to install these and so that there will be something to support the railings.^[i] Co-ordinate to handyman Walter Brant, "A railing made with pressure-treated wood can span nigh 8 ft (two.4 yard) between posts, while a PVC railing can merely have vi ft (ane.8 m) of space between posts. PVC isn't every bit strong as wood; plus the PVC railings you want may only come in half dozen ft (ane.viii m) lengths."

Measure out the posts. Cut 4x4s to be at least a lilliputian higher than the railing volition be, plus extra length to hang beneath the deck planks. For case, if you desire a railing that is 36 inches (91 cm) loftier, cut posts that are perhaps 44 inches (110 cm) high.^[2]
- Virtually building codes require deck railings to be between 36 inches (91 cm) and 42 inches (110 cm) high.
- The posts' actress height in a higher place the railing is just for looks. An inch or two higher than the railing will await nice.
- You'll demand plenty length hanging below the surface of the deck to adhere the posts securely to the supports. For case, if your deck is made of boards that are 1 inch (2.5 cm) thick and the supports are 6 inches (15 cm) loftier, then you'll want your posts to exist long enough to hang up to 7 inches (18 cm) but at least 4 inches (10 cm) beneath the railing
- Many people like to go out near 1.5 inches (three.viii cm) or then between the bottom railing and the deck boards as well, so cistron this into the post height as well.

Cutting the posts to accept an overhang. Mark a line that goes several inches up the side of the bottom of each post. For example, if you want your 4x4 posts to hang 4 inches (ten cm) over the edge of your deck, draw a line that far up the side, 2 inches (5.1 cm) from one side of the post (the midpoint of the post). Draw another line perpendicular to the first line'southward stop. Use a saw and cut along the lines yous drew to remove a section of the post that is 2 inches (5.1 cm) past 4 inches (10 cm).^[3]

Apply finish to the posts. If you programme on finishing your deck runway, go ahead and apply the terminate to the posts earlier installing. Brush the paint or stain on all sides of the posts and allow them dry (about 24 hours).

Mount the posts. Handyman Walter Brant suggests "belongings a post in the position where it will be mounted and using a big level to hold it in a vertical position." Adjacent, use a drill to form airplane pilot holes through the overhang of the posts into the deck joists. Then, drill lag screws or carriage bolts into the pilot holes.^[iv] If you volition be using lag screws, Brant advises "using two ¹⁄₂ in (1.3 cm)-diameter galvanized screws with washers, which are rust-proof. Drill ¹⁄₂ in (1.3 cm) holes through the mail service, followed by ^three⁄_eight in (0.95 cm) pilot holes into the board behind the post."
- If you volition use lag bolts, use ii ⁱ⁄_ii in (1.3 cm)-bore galvanized lag bolts with waters and basics. Washers are used simply on the ends of the bolts with the nuts. Drill ¹⁄_ii in (1.3 cm) holes through the post and the board backside it.
- If the posts will be higher than the railing (the railings will not be nailed to the tops of the posts), nail a metal or wooden post cap onto the top of the railing. This prevents water from entering at the top.^[5]

Marker the railing superlative on the posts. Using a tape measure, make a pencil mark in the heart of each mail service. This volition probably be betwixt between 36 inches (91 cm) and 42 inches (110 cm), according to your preference and edifice codes. Many homeowners similar to exit a couple of inches open beneath the lesser of the railing. To compensate for this, set the railing summit mark slightly higher than the pinnacle of the railing itself.^[six]
- For instance, if you want a railing that is about 36 inches (91 cm) loftier, make marks on the posts at 40 inches (100 cm). That will leave plenty room for the balusters, the summit and bottom of the rail, and a couple inches open up at the lesser.
ii
Mensurate the distance betwixt the posts. If you lot didn't install the posts yourself, y'all'll need to know the exact distance between them and then that you tin can cut the railing pieces to size. You'll need a helper for this.^[7]
- Ask your helper to concur one end of the tape mensurate in place against the center of a post.
- Stretch the record measure out tightly beyond to the center of the next post and make a mark.
- Tape the altitude between the posts.
- Bank check the distance where you want the top and bottom rails to sit. If your posts are straight, the distance should exist the same. If they're not, alter the length of the rails to match the actual altitude.

Get balusters and forest for the handrail. Accept a trip downward to the lumber supply shop. You'll need to become several pieces pre-cut or cut them to size yourself. Y'all can besides ask the supply store to cut information technology to size for y'all. Handyman Walter Brant suggests "using a miter saw if you lot program on cut the rails and handrails yourself."
- Cut 1x3 or 2x4 lumber into lengths equal to the distance betwixt your deck posts. You'll need two pieces for each length of railing (ane for the lesser and another for the top).
- Get plenty of 2x2 balusters to apply for the railing. You'll desire to space these no more 4 inches (ten cm) autonomously.
- The length of the balusters should be approximately the height y'all want the railing to exist. If they're likewise long, cut them down.
- Y'all'll also demand thin strips of woods. Go something that is about 0.25 inches (0.64 cm) by 1.five inches (iii.eight cm). Cut information technology into lengths equal to the distance between the deck posts. You'll need one strip per department.

Finish all of the wooden pieces. If yous want to utilise a finish to your deck, such equally a glaze of polyurethane or paint, exercise this earlier assembly. Coat all of the pieces on all sides, and let them dry for about 24 hours. That fashion, the pieces will be more than protected from weather conditions.^[viii] Handyman Walter Brant advises "sealing the terminate of each cut slice of wood to prevent water from entering. If the wood is non pressure-treated, paint the cut surface with exterior paint; if information technology is pressure-treated, press articulate exterior caulk into the surface."
- Really push the paint or caulk into place, because you want it to make full all of the pores.^[9]
- Make sure you've finished cutting, sanding and drilling everything before you utilise a finish.

Screw the foursquare cease of i baluster to the flat surface iii inches (seven.6 cm) from one end of the strip, and another three inches (vii.six cm) from the other end of the strip.^[10]
- Screws that are i.5 inches (3.eight cm) to 2 inches (5.i cm) should exist fine.

Position the other balusters and adhere them to the strip. Space the other balusters evenly along the strip between the two you already attached. Drive screws that are one.5 inches (3.8 cm) to 2 inches (5.1 cm) through the strip and into the ends of the balusters.^[xi]
- For instance, you could spread your balusters every 3 inches (7.6 cm) along the strip, then screw them in.
- If measuring out the identify for each baluster seems also tedious, take advantage of an online deck railing calculator to do the hard work for you.

Screw another sparse strip to the bottom of the balusters. Once you lot accept the tops of the balusters attached to ane of the strips, lay some other ane along their bottoms. Drive screws that are i.5 inches (3.viii cm) to ii inches (5.1 cm) long through information technology into the balusters. This will hold them all securely in place.^[12]

Secure the bottom rail to the posts. Use a couple of scraps of wood to hold the bottom rail up at the height you desire it to be. Pre-drill holes at an angle through its bottom, toward the posts. Then bulldoze long screws through these holes and into the posts and so that the bottom rails will stay securely in place.^[13]
- Screws that are 3 inches (vii.6 cm) to 4 inches (10 cm) long should be fine.

Bulldoze a few screws (that are no longer than your elevation rail is thick) from underneath, through the thin strip and into the lesser of the top rail. At present the pieces of the rail will be securely fastened to each other and to the posts.^[15]
