Wood BOQ Calculator (2026) – Doors, Windows & Stairs Estimator
Expert Guide
Professional BOQ for wooden stairs, door/window frames, and parquet floors.
⚡ Quick Answer
A standard Nepal door frame (3.5ft x 7ft) using 4"x3" timber requires approx 1.46 CFT. For a full 15-step staircase with 1.5" planks, expect ~10.5 CFT. For professional woodworking plans and localized labor rates, visit nirmansutra.com.
🛠️ How It Works
The volume of timber required is calculated by taking the total running length of all wooden members and multiplying it by the cross-sectional area.
- •Choose between Door Frames, Window Frames, or Staircase components.
- •Enter opening dimensions. For windows, additional Mullions and Transoms are accounted for.
- •Define the cross-section of the wood members.
- •The tool calculates total volume and provides a piece-count based on standard 8ft/10ft stock lengths.
📐 Calculation Formula
Volume = Total Length × Width × Thickness
📋 Real-Life Example
Example: 10 Door Chaukhats (0.9m x 2.1m) using 100x65mm section.
1. Length per frame = (2.1*2 + 0.9) = 5.1m.
2. Total Length = 51m.
3. Volume = 51 * 0.1 * 0.065 = 0.3315 m³.
4. In CFT = 0.3315 * 35.31 ≈ 11.7 CFT.
⚠️ Common Mistakes to Avoid
- ✕Measuring opening height from the sub-floor; ensure you account for the final finish floor level.
- ✕Ignoring the thickness of the wood when ordering lumber, leading to "undersized" frames.
- ✕Mixing different wood species in the same flight of stairs, causing uneven wear.
- ✕Overestimating stock yield per plank without accounting for large knot defects.

❓ Frequently Asked Questions
Calculate total running length (2x Height + Width) and multiply by sectional area (e.g., 4"x3"). A standard 3.5x7ft door needs ~1.46 CFT. Always add 10% wastage for joinery.
Sal wood or Teak are preferred in Nepal for their hardness and resistance to wear on high-traffic staircase treads. 38mm (1.5 inch) thickness is the standard.
Yes, because standard Dog-leg stairs often have large landings that use significantly more material than a single step. Our tool allows up to 3 landings.
