2. Size and thickness: Honeycomb cardboard can be customized into different sizes and thicknesses, and the specific size and thickness will affect the required quantity.

3. Demand: Consider the expected demand for your production or project. Might this involve a one-off purchase, or will supply be required on a regular basis?

4. Waste and extra quantity: Usually, when purchasing honeycomb paperboard, you need to consider a certain waste rate and extra quantity to deal with unexpected situations or errors in production.

5. Special requirements: If you have special requirements, such as custom printing, special processing or special specifications of honeycomb cardboard, this will also affect the demand.

The best course of action is to contact your honeycomb cardboard supplier with detailed project requirements and specifications so they can provide you with an accurate quote and recommendation.
