How do I know how many balusters I need for my railing?
Use the Deckorators ® baluster calculator to determine quickly how many balusters or spindles your railing requires. Balusters are the vertical guards that support the handrail. They must be installed close enough that the space between them is less than 4 inches. Most city inspectors carry a 4-inch ball with them to test the spacing.
How do you calculate baluster spacing?
To determine quantity required, take your rail length in inches and divide by 7.75. For square baluster spacing, simply add 3 7/8″ to the width, and that should be your on-center spacing. It will leave a 3 7/8″ gap between them:

How much pressure can balusters withstand?
Most city inspectors carry a 4-inch ball with them to test the spacing. Installed balusters should withstand 50 pounds of pressure exerted over a 1-sq.-ft area.
What length should stair balusters be?
Multiply the total distance by 3. This will tell you how many balusters you need. For example, if the total distance of your staircase is 15 feet, you'd need 45 balusters (15 x 3 = 45). If your total distance is not a whole number, it is important that you always round up.
Are all balusters the same length?
Balusters are manufactured in two different ways: 3-Length and 5-Length.
What height balusters do I need?
Baluster Height 3 Balusters per Tread: Each baluster should be one third of the riser height longer than the previous baluster per tread. 7 ½” Rise, 2 balusters per tread: Each baluster would be 3 ¾” taller than the previous baluster per tread, starting at the front of the tread. (7 ½” divided 2 = 3 ¾“).
How many balusters do I need calculator?
The general rule is that your railing must have three balusters per foot (every 12 inches), although you can place them closer together if you'd like.
Do stair balusters come in different lengths?
Sizes of iron balusters vary from 1/2″ to 9/16″, 5/8″ to 3/4″. They come round or square, solid iron, tubular steel, or stainless steel.
What is the legal gap between stair spindles?
The building regulations state that a 100mm sphere cannot pass through any opening and this includes between spindles. So your maximum space between spindles is 99mm.
What is the maximum gap between balusters?
U.S. building codes mandate that balusters have no more than a 4-inch gap between them. This relatively tight amount of spacing still allows for visibility between spindles, but also stands as a safety measure to prevent small children from becoming stuck between spindles or from slipping through the balusters.
How do you calculate railing spindles?
To determine the correct number of spindles for the guard, measure the length of the railing. Then, count the number of vertical guards and the measure the thickness of each. Next, multiply the number of spindles by the thickness, and then subtract this number from the length of the railing.
How do you space out even balusters?
To evenly space spindles quickly: Multiply your spindle's width by the number of spindles you need to find the total width of all your spindles. Say, 15 spindles × 3 cm = 45 cm. Subtract your spindles' total width from the railing length you will install them to get the total width of all the combined spaces.
How do you calculate balustrades?
Measure the length of the space between the end supports of the balustrade. For this example, assume it's 13 feet 5 ½ inches, or 161 ½ inches. Divide that length by four to determine the number of spaces you will need while having a minimum of 4 inches distance between balusters.
How do I calculate how many spindles I need?
It is as simple as that. To calculate the number of stair spindles required, count the number of treads (steps) on the single flight, making sure not include the landing area, multiply by two, and then subtract two (as you will only require one spindle on the top and bottom steps to make room for the newel posts).
How long should a stair rail be?
Before you go shopping for your handrails for stairs, measure from the nosing of the top landing to the floor at the bottom of the stairs and add 2 ft. This is the length of stair railing material you'll need.
What is the actual size of a 2x2 baluster?
2" x 2" Nominal Size (in.), 1-1/2" x 1-1/2" Actual Size (in.), 38 x 38 mm Actual Metric Approx. Dark reddish or purplish brown with white resin streaks present.
What sizes do spindles come in?
Spindle Sizes32mm.35mm.41mm.50mm.
Can Deckorators railing be cut?
Railing posts cannot be more than 6 feet apart (on-center). Once you've determined that the posts are good to go, you'll need to trim the post sleeves to length with a chop saw or circular saw. A carbide-tipped blade works best.
How high should a deck railing be?
If your deck ranges between 24 inches and 30 inches from the ground, local building safety codes require your deck to have a railing that is at least 3 feet (36 inches) high, extending from the deck’s surface to the top of the railing.
How far apart should spindles be on deck?
In order to comply with building regulations and codes, balusters must be spaced no more than 4 inches apart on center.
Do you need a railing on a deck?
However, if your deck is near a steep drop off, embankment, or cliff, you should include a railing for safety purposes. Your deck will require a railing that extends on both sides of your stairs, and around the perimeter of your deck.
How tall is a baluster?
Using three balusters per tread I compute that the first baluster will rise an additional (from the height of the handrail at the front of the bullnosing) height of 2.24 inches, the second 5.43 inches, and the third 8.62 inches. Each riser is approximately 10 inches.
How many inches can a stair be?
It says it can be 30" if one said of the stair is against a wall, 34" if both saids are open. I would go for the 34" no matter what for the added safety.
How many balusters per tread?
Thus you need at least 2.5 balusters per tread to meet code. So, we round up to 3 balusters per tread multiplied by the number of treads and there you have the number of balusters required for your stairway.
How to measure stair tread?
This is often confusing because people tend to measure from the back riser to the front of the tread nosing. If you are able to measure at the side of the stairway you can usually place the end of the tape against one riser and measure across the tread “eyeballing” the distance to the riser below it. If you don’t have access, such as in the case of a closed or kneewall stringer, just measure one full tread from the back riser to the nosing. Then measure how far the nosing sticks out beyond the riser below and subtract this from the first measurement. For example, if you have a measurement of 11 ¼” from the riser to nosing on top of the tread then 1 ¼” from the riser below to the nosing overhang you have a tread run of 10″.
How to find the spacing of a 10" tread?
Now, to find out the spacing you simply divide your 10” tread run by the 3 balusters per tread to get 3.3333 or 3 11/32” center to center.
Where is the post on a stair tread?
The post at the bottom of the stair is often notched into the tread nosing against the riser, in this case, the first baluster on that tread may be eliminated altogether depending on your spacing and layout.
How much space between balusters?
Square Balusters, Wood or Composite. For square baluster spacing, simply add 3 7/8″ to the width, and that should be your on-center spacing. It will leave a 3 7/8″ gap between them: 1 5/8″ wide Wood Baluster: 5 1/2″ on-center.
How many inches between spindles?
Spacing & Quantity: To meet the 4″ ball rule required by most building codes, space these spindles every 5 1/4″ On Center. The smallest diameter of the turned portion is approx. 1 3/8″, so with a 5 1/4″ O.C. spacing, you’ll have a 3 7/8″ gap between them at the narrowest portion. To determine quantity required, take your rail length in inches and divide by 5.25.
How to find the quantity of a rail?
To come up with the quantity, take the length of rail (in inches) and divide by the on-center spacing, and subtract one. You subtract one because they will be centered in the rail between two posts, columns, etc.
What is a baluster in a deck?
Balusters or pickets are the rail components used to provide infill for deck guardrails. IRC code prohibits guardrails from having any openings that would allow a 4" sphere to pass through.

A 45 Degree Angle. 1. Measure the distance between rail posts. Measure the inside corner to corner distance for angled rail sections. Cutting top and bottom rails. 2. Cut the 2x4 top and bottom rails to the proper lengths. We suggest that you use a miter saw and cut each railing section one at a time.
