Choosing plywood isn't just about picking any 8x4 sheet and getting started. One of the most critical decisions in any woodwork or interior project is selecting the right thickness for your plywood. The wrong thickness can cause sagging, breakage, or overengineering — leading to unnecessary costs.
Whether you're designing a wardrobe, building a kitchen cabinet, or creating wall paneling, this guide will help you decide whether you need 5mm, 12mm, 18mm, or 19mm plywood — or something else entirely.
Why Plywood Thickness Matters
The thickness of plywood directly affects:
- Load-bearing capacity
- Durability & lifespan
- Weight of the furniture
- Cost per sheet
- Ease of installation
Using overly thick plywood can increase project costs and weight, while under-thick panels may lead to breakage or bending over time — especially in areas like wardrobes or beds.
Standard Plywood Thicknesses in India
In India, the most commonly available plywood thicknesses include:
| Thickness | Application |
|---|---|
| 5mm | Back panels, drawer bottoms, panel inserts |
| 6mm | Paneling, light wall partitions |
| 12mm | Wardrobes, kitchen shutters, small furniture |
| 16mm | Medium-duty furniture, office desks |
| 18mm | Bed frames, heavy-duty furniture, base cabinets |
| 19mm | Commercial-grade or high-traffic usage furniture |
| 25mm | Structural work, stage/platform construction |
Plywood Thickness Recommendations by Use Case
Let’s dive deeper into project-specific recommendations using Plyneer’s premium plywood grades, like MR, BWR, and BWP.
1. For Modular Kitchen Cabinets
- Recommended Thickness: 18mm BWP or BWR Grade Plywood
- Why: Kitchens demand waterproof plywood that resists moisture, heat, and daily wear. An 18mm marine plywood or 710-grade plywood is ideal for cabinet carcasses, shutters, and countertop supports.
Suggested Plyneer Products:
- Plyneer Calibrated BWP 18mm
- Plyneer Gold BWP 710 Marine Plywood
2. For Wardrobe Shutters & Doors
- Recommended Thickness: 12mm or 16mm MR/BWR Plywood
- Why: Doors and shutters should remain light yet sturdy. Too thick a board adds unnecessary weight on hinges.
Tip: You can also use blockboard (19mm) for larger doors to prevent bending.
Suggested Plyneer Products:
- Plyneer X MR 12mm (Premium Quality)
- Neem MR Grade Plywood for cost-efficiency
3. For Bed Frames, Tables & Heavy Furniture
- Recommended Thickness: 18mm or 19mm BWR/BWP Grade Plywood
- Why: These areas need strength and load-bearing capacity. The structure must last years without sagging or splitting.
Suggested Plyneer Products:
- Plyneer Bullet BWR 18mm (Budget-Friendly)
- Plyneer X BWP 19mm (30 Years Warranty)
- Recommended Thickness: 5mm or 6mm MR Grade Plywood
- Why: These panels don’t carry much weight and need to remain lightweight. Go for moisture-resistant MR plywood for durability.
Suggested Plyneer Products:
- Plyneer Gold 5mm MR Plywood
- Plyneer Calibrated 6mm MR Sheet
5. For Bookshelves or Long Spans
- Recommended Thickness: 18mm BWR/BWP Plywood or Blockboard
- Why: Long shelves need strong support. Thinner plywood can bend under weight. Calibrated plywood is a great option for precision-cut designs.
Suggested Plyneer Products:
- Plyneer Neem Blockboard
- Plyneer X BWR 18mm
- Recommended Thickness: 6mm to 12mm MR Plywood
- Why: You want lightweight yet smooth surfaces for panel work. Use veneered plywood or laminate over it for design aesthetics.
Suggested Plyneer Products:
- Plyneer Interior MR 6mm/12mm
- Plyneer Saffron Recon Veneers on 6mm base
