Introduction

Acoustic panels have become one of the most important decorative and functional materials in modern architecture, interior design, and industrial construction. With the rise of open-plan offices, commercial spaces, and the increasing demand for sound quality in hotels, theaters, studios, and residential projects, acoustic panels are no longer considered optional but essential.

When buyers, designers, and project managers source acoustic panels, one of the most common and practical questions is: what are the standard sizes of panneaux acoustiques, and how do these sizes affect installation, cost, and performance?

This article provides a detailed, professional-level exploration of acoustic panel sizes, covering:

1. Standard dimensions of acoustic panels in the global market
2. Customized sizing options for different applications
3. Thickness variations and their acoustic implications
4. Size recommendations by application scenario (office, theater, studio, hotel, industrial, etc.)
5. How panel size impacts logistics, installation efficiency, and overall project costs
6. Emerging trends in acoustic panel sizing for international markets

This comprehensive analysis will help architects, contractors, wholesalers, and international buyers better understand the product range and make informed procurement decisions.

Standard Sizes of Acoustic Panels

1.1 Rectangular Panels (Most Common)

Rectangular acoustic panels are the industry standard. Their size is designed to balance ease of handling, surface coverage, and acoustic performance.

600 × 600 mm (2 × 2 ft)

• Widely used in ceilings (drop ceilings, grid ceilings).
• Easy to install in modular systems.
• Popular in commercial offices, classrooms, and call centers.

1200 × 600 mm (4 × 2 ft)

• One of the most popular sizes worldwide.
• Suitable for both wall and ceiling mounting.
• Provides a good balance of surface coverage and manageable weight.

1200 × 1200 mm (4 × 4 ft)

• Used in larger wall applications.
• Ideal for projects that need fewer seams for aesthetic purposes.
• Slightly heavier, requiring stronger installation systems.

2400 × 1200 mm (8 × 4 ft)

• A large-size panel, usually for high walls, theaters, or halls.
• Reduces seams for a smooth and continuous look.
• Requires careful handling due to weight and size.

1.2 Square Panels

Square sizes are commonly used when aesthetics and uniformity are prioritized.

• 300 × 300 mm: Often used as decorative tiles, creating patterns.
• 600 × 600 mm: The most widely used square size, compatible with ceiling grids.
• 900 × 900 mm: Less common, but chosen for unique design schemes.

1.3 Slat and Linear Panels

Acoustic slat wood panels, popular in the U.S. and Europe, have different standard sizes:

• 2400 × 600 mm (8 × 2 ft)
• 2800 × 600 mm (9.2 × 2 ft)
• 3000 × 600 mm (10 × 2 ft)

These panels combine acoustic felt backing with wood slats, creating both sound absorption and decorative effects.

1.4 Hexagon & Other Geometric Panels

For modern interiors, geometric acoustic panels (hexagon, triangle, trapezoid) are increasingly popular. Standard hexagon sizes:

• 300 × 300 mm per side
• 450 × 450 mm per side
• 600 × 600 mm per side

These panels are usually smaller and lightweight, suitable for design-driven spaces like cafes, restaurants, or creative studios.

Thickness Variations

Panel l'épaisseur is as important as length and width because it directly affects acoustic performance (sound absorption coefficient, NRC value).

• 9 mm – 12 mm: PET acoustic panels, lightweight, suitable for decorative and office use.
• 15 mm – 25 mm: Standard wall panels for hotels, offices, and classrooms.
• 25 mm – 50 mm: Professional-grade panels for theaters, recording studios, and conference halls.
• 50 mm – 100 mm: High-performance soundproofing panels, industrial environments, or special acoustic engineering projects.

Thickness determines both the absorption frequency range and installation methods. For example:

• Thin panels absorb mid-to-high frequencies.
• Thicker panels target low frequencies, making them essential for studios and cinemas.

Customized Sizes

Although manufacturers often provide standard sizes for efficiency, B2B buyers can request customized dimensions based on project requirements.

• Custom length/width: Panels can be cut to fit wall height or ceiling modules.
• Oversized panels: For large halls and fewer seams (e.g., 3000 × 1200 mm).
• Custom shapes: Logos, waves, circular panels for branding and design.

Customization usually increases cost due to cutting, wastage, and logistics. However, for high-end projects such as luxury hotels or auditoriums, customized sizes are a common requirement.

Size Recommendations by Application Scenario

4.1 Offices & Call Centers

• 600 × 600 mm ceiling tiles for grid systems.
• 1200 × 600 mm wall panels for workstation partitions.
• Thickness: 9–15 mm PET or fabric-wrapped panels.

4.2 Hotels & Restaurants

• 2400 × 600 mm slat panels for walls and ceilings.
• 1200 × 1200 mm fabric panels for banquet halls.
• Decorative geometric panels (hexagons) for lobbies.

4.3 Theaters & Cinemas

• 2400 × 1200 mm large panels to cover wide walls.
• Thickness: 25–50 mm for mid-low frequency absorption.
• Curved or wedge-shaped panels for sound diffusion.

4.4 Recording Studios & Broadcasting Rooms

• Smaller 600 × 600 mm ou 1200 × 600 mm modular panels.
• Thickness: 50–100 mm for maximum acoustic absorption.
• Custom bass traps (triangular or wedge-shaped) in corners.

4.5 Schools & Universities

• 600 × 600 mm ceiling panels for classrooms.
• 1200 × 600 mm wall panels for auditoriums.
• Thickness: 15–25 mm for speech clarity.

4.6 Industrial Applications

• Large 2400 × 1200 mm panels for factories and workshops.
• Thickness: 50–100 mm with fire-resistant and durable surfaces.

Impact of Size on Logistics & Installation

5.1 Handling and Transportation

• Smaller panels (600 × 600 mm) are easier to ship, stack, and carry.
• Larger panels (2400 × 1200 mm) reduce installation seams but require more space and careful packaging.

5.2 Installation Efficiency

• Fewer seams = faster installation for large-scale projects.
• Smaller panels = more flexibility in design but longer installation times.

5.3 Cost Implications

• Larger panels may reduce labor costs but increase shipping costs.
• Standard sizes are more cost-effective compared to custom dimensions.

Market Trends in Acoustic Panel Sizes

• Europe & U.S.: Growing demand for slat wall panels (2400 × 600 mm, 2800 × 600 mm).
• Asia-Pacific: Preference for modular ceiling panels (600 × 600 mm, 1200 × 600 mm).
• Middle East: Larger seamless panels (2400 × 1200 mm) for luxury hotels and conference halls.
• Global trend: PET felt panels in 9–12 mm thickness gaining popularity due to eco-friendly material and lightweight installation.

Comparison of Common Sizes

Conclusion

Les sizes of acoustic panels vary widely depending on material type, application, and market demand. From the compact 600 × 600 mm ceiling tile to the large 2400 × 1200 mm theater wall panel, each size serves a specific purpose. Thickness is equally critical, as it determines sound absorption performance across different frequencies.

For B2B clients—importers, distributors, and project contractors—understanding the standard and customizable size options is essential for optimizing procurement, logistics, and project outcomes. Whether it’s a modular office, a luxury hotel, or an industrial facility, selecting the right panel size can significantly improve installation efficiency, cost control, and acoustic effectiveness.
