Setting product weights and dimensions

Read time: 3 min

Add accurate weights and dimensions to ensure correct shipping rate calculations.

1

Open the product and scroll to the Shipping section

On the product edit page, find the Shipping section. Enter the weight in kilograms and dimensions (length × width × height) in centimetres.

2

Enter packed weight and dimensions

Enter the weight and dimensions of the packed parcel — not the bare product. This is what the carrier API uses to calculate live rates.

3

Account for dimensional weight

Carriers often charge by dimensional weight (L × W × H ÷ 5000) when it exceeds actual weight. Numu automatically uses whichever is higher to avoid billing surprises.

💡 Tip

Use an accurate scale and tape measure on packed parcels — estimated weights cause billing discrepancies that erode your margin.
