THE INDEPENDENT SELLER’S TOOLKIT
Small parcel.
Smarter decisions.
Know your shipping weight, find the right box,
and understand your packing costs. Before you seal it.
Dimensional weight calculator
Measure your packed box
Use the outside dimensions, including any bulges.
5,000 is an example metric divisor. Enter your service’s factor and rounding rule.
ESTIMATED CHARGEABLE WEIGHT
Your parcel’s size sets the higher weight.
40 × 30 × 20 ÷ 5,000 = 4.80 kg
Planning estimate, not a shipping quote. Service-specific dimension rounding, minimums and surcharges are not included.
