A Complete Guide to Plywood Thicknesses and Their Applications

Plywood is one of the most versatile materials used in construction and interior design. However, choosing the right thickness is just as important as selecting the grade or type of plywood. Each thickness has its own strength, durability, and application.

Here’s a complete guide to plywood thicknesses and how they are best used in interiors.

📏 Common Plywood Thicknesses

  1. 6mm Plywood

    • Best for: Paneling, backing, wall cladding, and decorative purposes.

    • Lightweight and flexible, but not suitable for load-bearing applications.

  2. 9mm Plywood

    • Best for: Light partitions, drawer bottoms, small furniture panels.

    • Offers more strength while still being easy to handle.

  3. 12mm Plywood

    • Best for: Shelves, moderate furniture, wall panels.

    • Provides a balance of strength and flexibility.

  4. 16mm Plywood

    • Best for: Medium-duty furniture, wardrobes, modular kitchen cabinets.

    • Strong enough for daily use with durability against wear and tear.

  5. 18mm Plywood (most commonly used thickness)

    • Best for: Heavy furniture like beds, dining tables, sofas, and countertops.

    • Ensures strength, durability, and long life.

  6. 25mm Plywood and above

    • Best for: Flooring, mezzanine structures, industrial furniture.

    • Provides extra load-bearing capacity and stability.

🏡 Applications of Plywood by Thickness

  • Furniture: 16mm–18mm for strength and longevity.

  • Kitchen Cabinets: 16mm–18mm moisture-resistant plywood.

  • Wardrobes: 12mm–16mm depending on design.

  • Partitions: 9mm–12mm for lightweight divisions.

  • Flooring: 18mm–25mm for durability under heavy load.

  • Wall Paneling: 6mm–12mm for decorative aesthetics.

🌟 Tips for Choosing the Right Thickness

  • Consider load requirements – heavier furniture needs thicker boards.

  • Check for moisture exposure – kitchens and bathrooms need MR or BWP plywood.

  • Balance cost and durability – thicker sheets cost more but last longer.

✅ Conclusion:
The right plywood thickness ensures strength, safety, and longevity in your interiors. Whether you’re building a wardrobe, designing a modular kitchen, or laying flooring, choosing the correct thickness helps you achieve durable and beautiful results.
