Baluster Calculator
If you're a fan of DIY home renovations and your project needs a railing, our baluster calculator is bound to be of immeasurable help to you! If you're working on a decking project or need railings for your stairs and upper floors, use this tool to save time and money that you would otherwise spend on calculations or hiring someone else to do it for you.
How to use the baluster calculator?
We have a rule that our tools should be as simple and intuitive as possible, so you are sure to find using the baluster calculator quick and easy! Follow this set of rules, and you will have the number of spindles calculated in no time.
 Start by inputting the length of your railing.
 The next step is to provide the baluster calculator with the number of posts.
 Next, input the width of a single post.
 Put in the width of a single baluster. If the balusters you chose have an irregular shape, input the width of the widest part.
 The last step is to put in the baluster spacing. Remember that the maximum spacing allowed in most areas around the world is 4"/99mm! In some cases, it might even be less, so make sure to check the construction regulations for your area before beginning your calculations. If the declared baluster spacing is too big, the calculator will inform you about it.
With all these values, the baluster calculator will return the number of balusters you will need for your project.
NOTE: as with all other construction works, it is always a good idea to buy a little more materials than you need to account for unexpected renovations and mistakes. We recommend an additional 10  15%. You may find our percentage calculator handy when calculating the exact amount.
Baluster calculator formulas & example
The baluster calculator is a real timesaver, but we understand that you might be in the mood to do the math yourself. To do so, use the following formula:
number of balusters needed = (railing length  (number of posts * single post's width)) / (baluster width + baluster spacing)
Remember to round the result up!
Now, let's go through an example to illustrate just how simple the process is. For clarity's sake, we will break the equation down into smaller parts.
Let's say that we want to build a railing which:
 is 20 feet long.
 has 5 posts that are 2 inches wide.
 will be made out of 2inchwide balusters.
 has 3 inches of baluster spacing.
With these numbers, the calculations will be as follows:
railing length  (number of posts * single post's width) = 20'  (5 * 2") = 240"  10" = 230"
baluster width + baluster spacing = 2" + 3" = 5"
number of balusters needed = 230" / 5" = 46
