1. Understand Your Product Dimensions

  • Measure length, width, and height of your product.

  • If the item is fragile or irregularly shaped, leave extra space for protective fillers (bubble wrap, thermocol, paper, air pillows).

Example: A glass jar will need more cushioning than a clothing item.

2. Consider the Box Strength (Ply Count)

Carton boxes come in 3-ply, 5-ply, 7-ply, and 9-ply varieties.

  • 3-ply: Best for lightweight items like clothes, books, stationery.

  • 5-ply: Suitable for medium-weight goods like electronics, packaged food.

  • 7/9-ply: Heavy-duty boxes for industrial products, machinery, bulk shipments.

3. Choose a Box Slightly Larger than the Product

Your carton should be 1–2 inches bigger than the product dimensions on each side. This allows space for filler materials to absorb shocks during transit.

Too small = risk of damage.
Too large = unnecessary shipping cost.

4. Match Box Size with Courier Requirements

Many courier companies in Siliguri (DTDC, Blue Dart, India Post, etc.) charge based on volumetric weight.

  • Formula: (Length × Width × Height) ÷ 5000 (in cm).

  • Choosing the right-sized carton helps reduce volumetric charges.

5. Standard Carton Sizes in Siliguri

  • Small: 8″ × 6″ × 4″ – accessories, cosmetics, small gadgets.

  • Medium: 12″ × 10″ × 6″ – clothes, books, food packets.

  • Large: 18″ × 12″ × 10″ – electronics, kitchenware, bulk goods.

  • Extra Large: 24″ × 18″ × 12″ – industrial parts, heavy packaging.

(Local suppliers in Siliguri can also customize cartons for your exact needs.)

6. Ask Your Supplier for Guidance

Most carton box manufacturers in Siliguri offer custom box design and testing. They can recommend the best ply and size based on your product type, shipping distance, and weight.

Key Takeaway

Choosing the right size carton box in Siliguri depends on product dimensions, box strength, courier rules, and protective space for fillers. For businesses, investing in properly sized cartons reduces damage, lowers shipping costs, and improves customer satisfaction.

If you’re unsure, consult a local Siliguri carton box supplier who can provide tailored solutions for your shipping needs.
