What is desi?
Desi is the weight equivalent of a parcel's volume (volumetric or dimensional weight). Because light but bulky parcels take up space, carriers bill on either kilograms or desi — whichever is greater.
How to calculate desi
Desi = Width (cm) × Length (cm) × Height (cm) ÷ 3000
Domestic carriers in Turkey commonly use 3000. International and air shipments usually use 5000 (some carriers differ — check your agreement).
Example
A 40 × 30 × 20 cm box: 40 × 30 × 20 = 24,000 ÷ 3000 = 8 desi. If it weighs 3 kg you are billed for 8; if it weighs 10 kg, for 10.
Common box sizes and their desi
| Box (cm) | Desi (÷3000) | Desi (÷5000) |
|---|---|---|
| 20 × 15 × 10 | 1 | 0.6 |
| 30 × 20 × 15 | 3 | 1.8 |
| 40 × 30 × 20 | 8 | 4.8 |
| 50 × 40 × 30 | 20 | 12 |
| 60 × 40 × 40 | 32 | 19.2 |
Ways to cut shipping costs
- Use the smallest box that fits; oversized boxes inflate desi.
- Mailer bags instead of boxes can reduce volume for soft goods like textiles.
- For multi-item orders, compare one combined box against separate parcels.
- Know the steps: 8.1 desi is billed as 9 on most tariffs.
- Selling on marketplaces? Include shipping in your profitability — commission calculator.
