How to read a shipping quote

7 min read· beginner· Updated Jul 9, 2026

A shipping quote looks simple until you notice two parcels of the same weight cost different amounts. Here is how to actually read one and pick the cheapest usable line.

Actual Weight vs Volumetric Weight

Couriers bill the greater of two numbers: how heavy your parcel is, and how much space it takes up.

A pillow is light but bulky, so it is billed on volume, not scale weight.

The volumetric formula

Volumetric weight in kg equals length x width x height in cm, divided by a divisor set by the line, commonly 5000, 6000 or 8000. A larger divisor means bulky parcels are punished less.

Couriers bill the greater of two numbers: your weight, or the space you take up.

What the Line Details Tell You

Before you pick a line, read the four things every quote shows you. Each one can quietly rule a line in or out.

  • ETA: the delivery window in days. Faster lines cost more per kg.
  • Carried categories: many lines refuse batteries, liquids, powders or branded goods.
  • Weight limits: some lines only appear above or below a certain weight.
  • First plus continued weight: price is usually a first-weight fee plus a per-kg rate after that.

How To Work the Ranked List

  1. 1
    Enter a realistic weight

    Weigh or estimate your consolidated haul, not a single item. Shipping is priced on the whole parcel.

  2. 2
    Add rough dimensions

    If your haul is bulky, dimensions matter. The tool computes volumetric weight and hides lines you would exceed.

  3. 3
    Filter by what you are shipping

    Select categories like battery or liquid so lines that cannot carry them drop out automatically.

  4. 4
    Read the ranked list

    The cheapest usable line sits on top. Check its ETA and carried categories before you commit.

Cheapest is not always usable

A line can be cheap because it refuses your item type. Always confirm the line carries your category and accepts your weight before ordering.
