Frequently Asked Questions

• Why does box size affect shipping cost?

  Carriers charge based on volumetric weight (L×W×H÷5000) if it exceeds actual weight. A correctly sized box minimizes this charge.

• How much padding should I add for fragile items?

  Add at least 5 cm of padding on all sides for fragile items to protect against impact during transit.

• How do I measure box dimensions for the calculator?

  Measure the length, width, and height of the box in inches or centimeters, using the longest side as length. Enter these values into the calculator to get accurate shipping label dimensions.

• Can the Box Dimensions Calculator handle irregularly shaped packages?

  Yes, for irregular shapes, measure the longest points in each dimension (length, width, height) as if the package fits in a rectangular box. The calculator uses these to determine dimensional weight for shipping.

• What is dimensional weight and how does the calculator use it?

  Dimensional weight is a pricing technique that considers package volume. The calculator multiplies length x width x height, then divides by a carrier-specific divisor (e.g., 139 for UPS/FedEx) to compute billable weight for labels.

• Does the tool support barcode generation for shipping labels?

  Yes, after entering box dimensions, the calculator can generate a barcode that encodes package details like size and weight, which you can print directly onto shipping labels for streamlined processing.
