Minimum Thickness for Rigid Boxes

The minimum recommended thickness for paperboard in custom rigid boxes is typically 1.5 millimeters (mm). This thickness provides a good balance of sturdiness and aesthetic appeal, ensuring that the box can protect its contents while maintaining a high-quality look and feel.


Why 1.5mm?

  • Durability: At 1.5mm, the paperboard is thick enough to withstand handling and shipping without bending or collapsing.

  • Aesthetics: This thickness allows for a smooth surface, which is ideal for printing and finishing techniques that enhance the visual appeal of the box.

  • Support: It provides sufficient support for heavier items, ensuring that the box retains its shape and integrity over time.


Factors to Consider

While 1.5mm is the minimum, the ideal thickness can vary depending on several factors:


  • Product Weight: Heavier items may require thicker paperboard for added support.

  • Box Size: Larger boxes might need thicker paperboard to prevent bowing or sagging.

  • Intended Use: Boxes designed for high-end retail or gifting purposes might benefit from thicker paperboard for a more luxurious feel.


For custom rigid boxes, starting with a minimum paperboard thickness of 1.5mm is a good rule of thumb. This thickness ensures durability and a high-quality appearance, making it suitable for a wide range of products. However, always consider the specific needs of your product and use case to determine if a thicker option might be more appropriate.
