How is baluster height measured?
Easiest Method Possible To Measure Height Of Stairway Guardrail
Handrail height on the stairs should be no less than 34 inches and no greater than 38 inches. The way this is measured is to begin at the leading edge of the stair nosing and run an imaginary vertical line upward until it reaches the top of the railing.
Two Balusters per Tread – Spindle/Baluster Spacing
Center to Center Spacing: Simply take the tread run divided by the number of balusters per tread. So let's assume a tread run of 10 and begin with a 2 baluster per tread pattern. So we take 10 ÷ 2 = 5.

Typically floor level balustrades must be at least 36” high or 42” high, depending on local codes and stair guardrails must be between 34” and 38”.
To determine the newel length, add the reveal (the distance from the top of the newel square to the top of the rail), the desired rail height (usually between 34 and 38-inches, refer to local building codes), the slope difference, and the riser height. Please note Fig. 4-4 here. 4.
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.
OSHA Standards
1910.23(e)(2) A stair railing shall be of construction similar to a standard railing, but the vertical height shall be not more than 34 inches nor less than 30 inches from an upper surface of top rail to the surface of tread in line with the face of the riser at the forward edge of the tread.
Guards for residential decks and balconies need a height between 36 inches and 42 inches, depending on the height of the surface above grade. The required height for railings is between 34 inches and 38 inches, measured above the finished stair tread nosings.
- A – Drop a plumb line from the front nose of the top of the stairs to ground level. ...
- B – Measure from top of landing to ground level. ...
- C – Measure from the post face to the front nose of the top stair (Please advise if there is an existing Post or post needs to be supplied)
How are spindles measured?
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.
- Measure the length of the space between the end supports of the balustrade. ...
- Divide that length by four to determine the number of spaces you will need while having a minimum of 4 inches distance between balusters.
Measure from the floor to the bottom of the handrail. Add 3/4″ onto that measurement and this is how long you should cut your iron baluster. This gives you enough room to slide the baluster up into the handrail and then drop it down into the tread and still have enough baluster to glue in place.

General Baluster Spacing – The general rule of thumb is to have 3 baluster per foot so you do not have any gaps greater than four inches. If you put one baluster every 4 inches on center, then you will typically always be fine.
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.
