How do you calculate spindle spacing?

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 far apart should deck spindles be?

4 inches
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 spacing?

Add the width of your object to the total space you want to fill. In the example given, it would be 223-1/2″. This is distance “A”. Regardless of the actual size of the end posts, columns or buildings, this will give you equal spacing for posts to be added between them.

How far apart should deck railing posts be?

six feet
The structural integrity of the railing depends heavily on the posts that support the rail structure. These posts should be no farther apart than six feet on the flat deck and no farther apart than 5 1/2 feet on stairs.

How do I figure out 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 do you evenly space balusters on stairs?

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.
