Furniture estimates of plywood Guidelines for Carpenter, site Supervisor & Houseowners

Here’s the same decision-flowchart with approximate cost estimates added (based on typical plywood brand, quality). Use these as rough guidelines — actual costs vary by brand, quality, region, and thickness.

🧮 Decision Flowchart with Cost Estimates (Grade + Thickness + Approx. Cost Depends on Brand, Quality)

1. Situation- Dry-area

Furniture Use- light/normal furniture (bedroom, living room — e.g. wardrobes, TV units, tables) 

Grade & Thickness- MR Grade plywood — 18 mm (body), 12–16 mm (drawers/partitions), 6–9 mm (back) 

Sheet- 8×4 sheet (18 mm) depending on brand/quality

2. Situation- Moderate moisture / semi-wet area

Furniture Use- furniture (kitchen wall cabinets, utility units, furniture near windows / humid zones) 

Grade & Thickness- BWR plywood — 16–18 mm (cabinets), 6–9 mm (back)

Sheet- 8×4 sheet (18 mm)

3. Situation- Wet-area furniture / high moisture exposure

Furniture Use- (kitchen base cabinets, bathroom vanities, sink units, outdoor-facing furniture) 

Grade & Thickness- BWP / Marine plywood — 18–19 mm (carcass / body / shutters), 9 mm (back)

Sheet- 8×4 sheet (18 mm)

 

4. Situation- Heavy-load / long-lasting 

Furniture Use- furniture in dry areas (beds, large storage units, wardrobes with heavy load)

Grade & Thickness- MR or BWR plywood — 18–25 mm for structure, 18 mm shelves, 6–9 mm back Use same range as MR / BWR above; higher thickness increases total cost proportionally

*Costs are approximate prevailing rates — Actual cost depends on brand, veneer quality, finishing, regional supply & taxes.

🎯 How to Use This on Site :-

1. While planning furniture, first identify the area (dry / semi-wet / wet).

2. Then choose plywood grade & thickness based on usage and load.

3. Compute total plywood sq ft required (using your estimation formula) → multiply by appropriate cost per sq ft ≈ gives you estimated material cost.

4. Add budget for wastage (10-15%), edge sealing / finishing, and labor to get full project cost.

✅ What This Helps You Estimate :-

1. Material cost differences between using cheaper MR vs premium BWP.

2. When extra cost is justified (for moisture resistance or durability).

3. How cost increases with thickness or higher-grade ply.
