Remove one spindle and measure its total length, top and bottom dowel diameters (if present), and the distance between rails where it actually sits. If you’re unsure, send a photo with a tape measure next to it. A woodturning supplier can likely size-match it for you before production.
Why Accurate Spindle Measurement Matters
Even small variations in spindle height or dowel diameter can cause alignment issues or gaps when reinstalling. Take the time to measure precisely to ensure that your replacements fit into your current stair system without needing to rebuild or modify the handrail.
Most stair systems follow standard spacing and pitch. However, older homes often have custom variations. Providing accurate, real-world measurements allows a manufacturer like Arnold Wood Turning to replicate your existing spindles exactly.
What to Measure Before Ordering
- 1
Total length: Measure from the very bottom of the spindle to the top (including dowels or tenons).
- 2
Between-rail distance: Measure the vertical space between your bottom and top rails where the spindle actually fits.
- 3
Top and bottom dowel diameters: If your spindles have dowels that sit inside the rail, measure their thickness.
- 4
Square or turned section height: Identify how much of the spindle is square and how much is round, especially near the base.
If you’re replacing a broken spindle, remove one that’s fine to use as your reference piece.
