Importer Planning Data
Curtain Fabric Weight and Freight Planning Data Guide
Use measurable inputs—not a generic “curtain weight”—to prepare an early logistics budget for hotel, wholesale, or private-label orders. The final shipping basis must come from approved specifications and the supplier’s packing list.
Data Set to Collect Before Estimating
| Input | Unit | Buyer check |
|---|---|---|
| Finished quantity and size | pieces; width × drop | Separate room types, pairs, and single panels. |
| Face fabric and lining weight | g/m² (GSM) | Use supplier test or specification values, not appearance. |
| Usable fabric width | metres | Exclude selvedge or unusable coated edges where relevant. |
| Consumption allowance | metres or % | Include hems, heading, matching, shrinkage, and cutting loss. |
| Accessories | kg/order | Hooks, rings, eyelets, tapes, labels, bags, inserts, and cartons. |
| Packed dimensions | cm/carton | Confirm after folding and packaging trials. |
Core Weight and Volume Formulas
Fabric net weight (kg) = fabric area (m²) × GSM ÷ 1,000.
Fabric area (m²) = ordered length (m) × usable width (m).
Estimated gross weight = fabric net weight + lining + accessories + packaging.
Carton CBM = length (m) × width (m) × height (m); total CBM = carton CBM × carton count.
When fabric is bought by linear metre, weight per linear metre can be estimated as GSM × usable width ÷ 1,000. Keep face fabric, lining, and interlining as separate rows so a specification change can be recalculated.
Worked Example: 600 Blackout Panels
Assume the approved consumption is 3.20 linear metres per panel, usable width is 1.50 m, and fabric weight is 280 GSM.
| Ordered fabric length | 600 × 3.20 m = 1,920 m |
|---|---|
| Fabric area | 1,920 m × 1.50 m = 2,880 m² |
| Estimated face-fabric net weight | 2,880 × 280 ÷ 1,000 = 806.4 kg |
| Illustrative added packing/accessory allowance | 806.4 × 12% = 96.8 kg |
| Early gross-weight planning figure | Approximately 903 kg before supplier confirmation |
The 12% line is an example assumption, not a site-wide rule. Retail boxes, metal eyelets, heavy interlining, hangers, room-by-room kits, or compression packing can change both gross weight and CBM.
Use Weight and CBM Together
Air cargo may use actual or dimensional weight, while sea LCL planning commonly depends on both volume and weight rules. Container planning also depends on carton geometry and loading efficiency. Ask the forwarder which chargeable basis applies to the specific route and service.
- Request a supplier packing-list draft after the packaging method is approved.
- Compare net weight, gross weight, carton count, carton dimensions, and total CBM.
- State the Incoterm and named place or port when requesting logistics prices.
- Separate sample courier costs from bulk-order freight.
Limitations and Commercial Use
This guide does not provide live freight rates, carrier space, customs duties, insurance, port charges, or guaranteed transit times. Fabric GSM may have production tolerance, and packed dimensions can change after the folding trial. Obtain a current forwarder quotation after cargo-ready data is confirmed. Incoterm responsibilities should be written clearly; buyers can consult the ICC’s official Incoterms rules information.

Frequently Asked Questions
Can GSM alone predict the final shipment weight?
No. Add confirmed consumption, lining, trims, hardware, labels, inner packs, cartons, and pallet or crate weight where used.
Should an estimated freight rate be used in a purchase contract?
No. Use a current written logistics quotation tied to confirmed cargo data, route, Incoterm, service, and shipment window.
What should be sent with a freight-ready RFQ?
Send sizes, quantities, construction, GSM, lining, packaging method, destination, target cargo-ready date, and any room-by-room or retail packing requirements.
Turn Planning Data Into a Supplier Check
Share the calculation sheet as an RFQ appendix and ask the supplier to replace every assumption with an approved or measured value before booking transport.
