Optimise how products fit in the box to reduce space waste and shipping costs.

Why package geometry matters

Couriers charge based on actual weight or dimensional weight — whichever is greater. Dimensional weight (DIM weight) is calculated from the box's external dimensions, not just what is inside it. A large box with a small, light item inside will be charged at a premium DIM weight rate even though the item itself barely weighs anything. Choosing the right box size for the contents directly affects your shipping costs.

Beyond cost, over-sized boxes require more void fill material, take up more van space per delivery, and create a poor unboxing experience for the customer. Package geometry helps you match the right box to the contents.

What Nexlymate shows you

• Visualise how items in an order fit into each of your registered box sizes
• See which box size leaves the least wasted volume for a given set of items
• Calculated dimensional weight for each box option — compare actual vs DIM weight to see which billing applies
• Flag orders where the selected box size creates significant DIM weight uplift
• Register your standard box sizes and their dimensions once — Nexlymate uses them for every order

Setting up your box dimensions

In Nexlymate, you register each box size you use — small, medium, large, mailer, etc. — with its internal dimensions (length, width, height) and maximum weight capacity. You also record the dimensions of each product in your catalog. From these two data sets, Nexlymate can calculate how items physically fit into each box option.

Cost reduction over time

For sellers shipping hundreds of parcels per month, consistently choosing boxes that are one size too large adds meaningful cost through DIM weight charges. If a product that fits in a small box is routinely shipped in a medium box, the DIM weight difference may add Rs. 50-150 per shipment. At 200 shipments per month, that is a significant unnecessary cost that package geometry helps identify and eliminate.
