How to Choose the Right Plywood Thickness for Furniture – A Practical Guide

Choosing the right plywood thickness is one of the most important steps in furniture making. Each piece of furniture carries a different weight and purpose, and the thickness of plywood decides how strong and long-lasting it will be. A clear understanding of how plywood behaves helps ensure the furniture remains stable and reliable for years.

Different furniture types, such as cabinets, tables, or wardrobes, need plywood of suitable thickness to perform well. The choice depends on the furniture’s use and the load it must handle. At Greenply, we offer a wide range of options that help in selecting the right plywood thickness for wardrobes and other furniture applications with confidence and ease.

Understanding Plywood Thickness

Plywood is formed by layering thin wood veneers with alternating grain directions, which defines its thickness and stability. Available from 4mm to 25mm, thinner sheets are suited for light panels, while thicker boards handle heavier applications. Using a plywood thickness guide ensures each sheet is chosen to match its intended furniture or interior function accurately.

Common Thickness Options and Their Uses

Plywood is manufactured in a range of thicknesses, allowing each grade to provide the required load bearing strength and structural support for its specific furniture or interior application.

4mm

4mm plywood provides excellent flexibility and ease of handling. It is suitable for lightweight panels that do not bear heavy loads, ensuring stability in installations while remaining simple to cut, shape, and align for accurate fitting in furniture and interiors.

Applications:

Suitable for lightweight partitions separating spaces.
Can be applied to false ceilings supporting decorative finishes.
Works for cabinet backs that require proper alignment.

6mm

6mm plywood offers slightly more rigidity than 4mm while remaining easy to work with. It provides moderate strength for panels that support light use without heavy structural requirements, making it a reliable choice for furniture interiors and decorative partitions.

Applications:

Effective for drawer bottoms in kitchens or living areas.
Suitable for internal panels in modular furniture.
Recommended for decorative partitions or lightweight cabinets.

9mm

9mm plywood balances strength and manageable weight. It ensures adequate rigidity for furniture panels that need extra support while remaining lightweight enough for smooth handling during installation and alignment for decorative or functional applications.

Applications:

Suitable for modular wall panelling in interiors.
Can be used for medium-strength furniture components.
Effective as a base for veneers or laminates requiring support.

12mm

12mm plywood combines durability with ease of handling, making it suitable for medium-load furniture applications. It provides long-term support and reliability for panels that carry regular wear and ensures proper stability for cabinets, shelves, and wardrobe interiors.

Applications:

Ideal for wardrobe panels supporting daily use.
Works for table tops requiring moderate durability.
Suitable for shelving units or indoor structural panels.

16mm

16mm plywood features a moderate thickness that delivers consistent panel stability and resistance to bending under regular pressure. Its structure allows for smooth handling and precise alignment, making it suitable for components that require controlled rigidity without adding excessive weight.

Applications:

Recommended for small room partitions needing durable support.
Suitable for staircase underlays carrying a moderate load.
Works for cabinetry panels that handle regular use.

19mm

19mm plywood provides firm stability and resistance to bending, suitable for applications requiring consistent support over time. Its properties make it reliable for panels or surfaces that experience frequent handling or pressure in both furniture and construction uses.

Applications:

Flooring that experiences daily wear and pressure.
Wardrobe panels that hold heavier garments.
Desks and countertops supporting substantial items.

25mm

25mm plywood is the thickest option, offering excellent stability and rigidity for applications that require maximum support. Its substantial thickness ensures panels retain shape under heavy weight, making it suitable for major furniture structures, shelving, and flooring bases where reliability is crucial.

Applications:

Structural supports in large furniture frameworks.
Shelving units designed to carry heavy loads.
Flooring bases requiring strong, stable panels.

Factors to Consider Before Selecting Thickness

Selecting the appropriate plywood thickness depends on multiple considerations to ensure the material meets its intended use effectively.

Load Capacity: Evaluate the weight the panel or furniture component must support to avoid bending or sagging over time.
Functionality: Match thickness to the specific furniture type or structural requirement to ensure practical performance.
Environmental Exposure: Consider conditions such as humidity, temperature, and indoor or outdoor placement for lasting stability.
Hardware Fit: Ensure screws, hinges, or fittings align correctly with the thickness to allow secure assembly and reliable use.
