How to Measure Stairs for New Balusters

  • Measuring Baluster Height

    Measure the distance from the bottom of the handrail to the top of the stair tread. Add 1.25 inches to this measurement to get your baluster cut length.

  • Measuring Height For Angled Stair Sections

  • Measuring Angles

    Angle cuts are recommended for angled sections of your stairs to ensure the balusters fit perfectly with the handrail.

    You can use a smartphone app called Handy Bubble Level DIY on iOS or Bubble Level on Android to measure the angle of your stairs.

    The tolerance of your angle measurements can be off by ± 2 degrees and still fit fine.

What happens if I measured my balusters are too long?

If a baluster is too long, you can cut both solid and hollow balusters with a powered cutting tool or angle grinder.

What happens if I measured my balusters too short?

Use a combination of methods for best results if your baluster is only slightly too short (around ¼″). Insert wood or plastic shims into the hole (for square installs) to slightly raise the baluster. Apply construction-grade epoxy in the floor and/or handrail holes for added grip. Finally, cover the gap with a baluster shoe (with set screw) and tighten the set screw to lock everything securely in place.


If the baluster is significantly shorter than needed, contact us. If you’ve ordered from us before, we can offer a 15% discount on replacement pieces.

What happens if the angle isn't measured properly?

You can re-cut the angle using a powered cutting tool or angle grinder, or you can contact us. If you’ve ordered from us before, we can offer a 15% discount on replacement pieces.

Threaded Holes (Drill & Tap)

  • Threaded holes (drill & tap) are needed if you are installing using a metal bar that is used to secure the balusters that sits under the wooden handrail. Threaded holes are 1/4"-20. If you need compatible screws, you find them here.

  • We can drill & tap balusters if it's angled at the top or if it's flat (landing).

    Thru holes are for drilling directly into a wooden handrail. The baluster inserts into the hole and is secured with screws.


    Threaded holes are for screwing the baluster into a metal bar or plate hidden underneath the handrail. This allows for a cleaner, surface-mounted look with mechanical fastening.

Countersunk Thru Holes

  • Drilled thru holes with a countersink are needed if you are securing the balusters directly into the wooden handrail without the use of a metal bar. Counter sunk thru holes are 7/32". If you need compatible wood screws, you can find them here.

  • We can drill countersunk thru holes if it's angled at the top or if its flat (landing).

Powder Coating

  • Powder coating is not strictly necessary, but it is highly recommended for balusters. Powder coating is used for aesthetic appeal and as a protective layer. It is applied as a dry powder and cured under heat. It provides a tougher finish than traditional paints and is more resistant to scratching, chipping, and fading.

  • Our powder coating services come in a variety of colors, with custom colors available upon request.
