Packaging Design Guide: How to Choose the Right Box

A comprehensive guide to selecting the perfect box structure, measuring dimensions, and matching materials to your product needs.

Which Box Structure Fits Your Product?

Collapsible rigid boxes with magnetic closure. Ship flat, assemble in seconds. Best for premium gifts and cosmetics.

Slide-out tray design with outer shell. Elegant unboxing experience for jewelry and electronics.

Separate top and bottom pieces. Classic and versatile for food, tea, and retail products.

Hinged cover that opens like a book. Unique storytelling format for luxury brands.

Pre-lined with soft cotton padding. Ready-to-use for delicate items like jewelry and watches.

Self-locking corrugated boxes for e-commerce shipping. Durable, branded, and cost-effective.

Branded shopping bags with handles. Extends retail brand identity to online orders.

Ribbons, inserts, tags, and dividers to complete your packaging presentation.

How to Measure Your Box Dimensions

Step 1: Measure Your Product — Determine the exact length, width, and height of your product. Add 2-5mm tolerance for comfortable fit.

Step 2: Calculate Internal Dimensions — If using inserts (EVA foam, pulp tray), add insert thickness to your product dimensions. The internal box size must accommodate product + insert.

Step 3: Determine External Dimensions — Add board thickness (typically 1.2-3mm greyboard) to internal dimensions. This gives the final box size for shipping calculations.

Pro Tip: Always specify dimensions as Length x Width x Height (L x W x H) in millimeters. Our design team can help optimize dimensions to minimize shipping costs.
