Volumetric Weight Calculator
Work out dimensional weight and the billable shipping weight from your box measurements, with a DIM factor of 3000, 4000, 5000 or 6000. Runs in your browser.
The dimensional weight divisor in your carrier contract.
Dimensional (volumetric) weight = width × length × height ÷ 3000 (the DIM factor) · Chargeable weight = the greater of dimensional and actual weight

Carriers use different DIM factors (3000/4000/5000/6000) for centimetres and kilograms; pick the one written in your contract.
Tips
- Enter the outer dimensions of the packed carton in centimetres and the real mass in kilograms.
- Pick the DIM factor from your carrier contract: 3000 is common domestically, 5000 for international air express.
- The billable weight is always the greater of dimensional weight and actual weight.
How to use it
- 1 Enter the outer length, width, and height of your packaged box in centimeters.
- 2 Enter the actual measured mass of your package in kilograms.
- 3 Set the DIM factor to the divisor in your carrier contract: 3000, 4000, 5000 or 6000.
- 4 Review the computed dimensional weight alongside actual weight to see which one determines your billing tier.
What you should know
Couriers charge freight rates based on billable shipping weight rather than actual scale mass alone. When handling lightweight yet bulky parcels such as apparel, pillows, or assembled toys, cargo space in transit vehicles becomes the limiting factor before payload weight capacity is reached. Freight carriers calculate dimensional volume in cubic centimeters and divide it by a standard volumetric factor, typically 3000, 4000, or 5000 depending on carrier contracts and transport modes. The carrier then bills whichever figure is greater between the volumetric weight and the measured physical weight.
This calculator computes dimensional weight instantly in your browser without transmitting parcel specifications or merchant data over the network. Enter the outer dimensions of your packaged box alongside its real weight to evaluate which tier applies to your shipment. You can adjust the DIM factor — the volumetric divisor — to 3000, 4000, 5000 or 6000 to match agreements with domestic carriers or international freight forwarders, as well as fee brackets on e-commerce marketplaces like Turkish marketplace Trendyol or global platforms. Identifying over-dimensioned packaging allows e-commerce sellers to trim box measurements and reduce overall freight expenses.
Frequently asked questions
Why do couriers use different volumetric divisors like 3000 or 5000?
Different logistics networks and transport modes use varying cubic conversion formulas. Domestic road couriers often use a divisor of 3000, while international air express carriers typically use 5000 or 6000. Check your specific carrier agreement to choose the right divisor.
Should I measure the unboxed product or the final packed carton?
Always measure the external dimensions of the final packed shipping box. Packaging tape, void-fill padding, and the outer carton thickness all contribute to the final cubic space occupied in courier vehicles.
How do marketplace shipping tiers determine fee brackets?
Marketplaces such as Trendyol, Hepsiburada, and global merchant platforms assign shipping rate tiers to defined volumetric and weight intervals. The platform bills your order using whichever value is larger, so optimizing box dimensions directly keeps your parcel in a lower fee bracket.
