What should I measure?
Measure the finished floor-to-floor height vertically, the width across the stair and the horizontal space available. Include project notes and confirm whether your finished levels are still changing.
Does the calculator confirm compliance?
No. The calculator is an indicative geometry tool. Final design, structural support, landings, headroom, handrails, barriers and slip resistance require project-specific checks.
Merbau timber stairs
Merbau is the timber choice for this range. Ask for the supplied board section, surface profile, finish requirements and any exposure-specific care instructions. A timber name alone does not establish slip resistance or project suitability.
Dimensions: what the selector means
The standard enquiry selector offers 1–17 separate treads, calculated at 165 mm per rise. With the upper landing as the final walking surface, this means 2–18 risers and an indicative total rise of 330–2,970 mm. These choices describe an enquiry, not stock availability. Select Custom for your actual measured height.
The width field records your requested dimension; it is not a list of manufactured sizes. Label whether it means tread length, clear walking width or outside-to-outside width. Confirm the going, board depth, thickness, nosing and any centre supports before ordering. See the complete rise table and labelled stair diagram.

| Delivery | Destination postcode, freight cost, access, unloading arrangements and agreed dispatch or collection timing. |
How to order a stair kit or components
- Measure the finished vertical height, available horizontal space and required width. Record obstructions and landing positions on the printable checklist.
- Select your range and add it to the quote. For a different layout, use the custom stair calculator. Its geometry remains indicative.
- Send the quote request with your postcode and project notes. Send plans or photographs separately to sales@diytimberstairs.com.au, using the quote reference when available.
- Review the written specification, price, availability, lead time and freight before agreeing to an order. No payment or order is placed by the website quote form.
Assembly and installation planning
Before assembly, reconcile the supplied parts and drawings with your approved specification. Have the installer confirm supports, connections, finished levels and site conditions. Follow the instructions supplied for your actual kit, including any timber treatment or finishing requirements. Our installation planning guide is a preparation checklist; it does not replace current product instructions or a site-specific design.
Check the applicable building requirements with your building surveyor or relevant practitioner. Stair geometry alone does not assess structural loads, landings, headroom, barriers, handrails or slip resistance. The Victorian regulator explains stair and barrier structural documentation. Requirements depend on the building, jurisdiction and applicable code edition.
