Why it matters
Dimensional weight is calculated from length × width × height ÷ divisor. Missing any dimension defaults carriers to assumed values, often inflating shipping cost.
Width pairs with length and height to compute dimensional weight. Common operational failure: feed pipeline populates length and height from product data but leaves width empty (some systems track 2D dimensions but not 3D). Carriers fall back to assumed values; shipping cost calculations inflate.
The precision: round to nearest centimetre or inch. Carriers round up at billing time, so over-precision in the feed adds no value. A 14.7 cm width gets billed as 15 cm regardless.
For irregularly-shaped items, use the bounding-box width — the longest measurement across the width axis. Carriers ship rectangular packaging; the bounding box determines cost.
