Balusters are the uprights that sit between the top and bottom rail. Due to visibility of balustrades we have come up with balusters, both square and turned that add to the interior design of your home. Wanting to find out how many balusters you need, simply use our formulas at the bottom of the page.
Our baluster range comes in two available lengths:
- 810mm For use with a bottom rail
- 1000 & 1200mm For use without a bottom rail
45mm Stop Chamfered
Note: Cutting will be required to the baluster to get desired length and angle, drilling will be required for dowels into top and bottom rail.
How MANY BALUSTERS DO I NEED?
The national building regulation calls for a gap between balusters to be no greater than 100mm. All of our balusters are either 32 or 45mm, so to work out how many you need, you can work it out using the following calculation.
For 32mm Balusters: Length of rail (mm) / 132 = No. Balusters Needed
For 45mm Balusters: Length of rail (mm) / 145 = No. Balusters Needed
Note: Always round down.
I have a rail needed with a length of 1250mm and I am using 32mm balusters.
1250 / 132 = 9.47 - Rounded down to 9 Balusters Needed
HOW DO I WORK OUT MY CENTRES?
Centre marks are needed to make sure that the space between balusters and newel posts are the same between each baluster. It will also allow you to check whether the gaps between balusters exceeds 100mm or not. For an exact centre to centre measurements and gaps between balusters you can use the following formulas.
Length of rail / (No. Balusters + 1) = Centre to centre of balusters
Centre to Centre Measurement - Thickness of Baluster = Gaps between balusters
I have a rail that is 1130 in measurement and using 45mm balusters. Using the first formula I have determined I need 7 balusters.
1130 / (7 + 1) = 141.25mm Centre to Centre
141.25 - 45 = 96.25mm Gaps between balusters
