Volumetric Shipping Weight Calculator

Desi is the unit Turkish carriers use to price the space a parcel takes up like weight. For light but bulky parcels the shipping fee follows desi, not kilograms.

Formulas

• Volume (cm³) = length × width × height
• Calculated desi = volume ÷ divisor (rounded up to 2 decimals)
• Rounded-up desi = next whole number of the calculated desi
• Billable desi = next whole number of max(calculated desi; actual weight in kg)

The divisor is a carrier convention, not a law. 3000 is common for domestic road parcels; air freight and some express services use 5000 or 6000. Change the divisor field to match your contract.

Example 1: a 25 × 21 × 17 cm parcel at divisor 3000: volume 8,925 cm³, calculated desi 2.975 → 2.98, rounded-up desi 3.

Example 2: a 45 × 30 × 20 cm parcel at divisor 3000: volume 27,000 cm³, desi 9.

Example 3 — a different divisor: a 50 × 40 × 30 cm parcel at divisor 5000: volume 60,000 cm³, desi 12.

Example 4 — weight is higher: a 30 × 20 × 10 cm parcel weighing 5.2 kg has volumetric desi 2, but since the weight is higher the billable desi is 6.

How to read the result: calculated desi is the raw volume-based value; rounded-up desi is the whole number to which most tariffs round fractional desi. Billable desi, if you entered the actual weight, is based on the larger of volumetric desi and weight and is the value that sets the shipping fee. Each carrier applies its own measuring and rounding rules, so the result is an estimate; use the contract shipping cost tool for pricing.
