Cargo Dimension Scanner — FAQ
How accurate is the measurement?
Accuracy depends on three things: the quality of the reference object measurement, how flat-on the photo is taken, and how precisely you click the endpoints. On a straight-on photo with a clear reference, results are typically within 2–5% of actual dimensions. For critical freight bookings, always verify with a tape measure.
What reference objects work best?
Flat objects with clearly defined edges work best: an A4 or A5 sheet of paper, a credit card, a business card, or a pallet board. The reference object should be in the same plane as the cargo face you are measuring — lying flat on the floor next to the box, not propped against it at an angle.
Does perspective affect accuracy?
Yes. The more the camera is off-axis (not pointing straight at the cargo face), the more perspective distortion skews the measurements. For best results: shoot from the same height as the midpoint of the cargo face, keep the camera level, and make sure the reference object is in the same plane as the face you are measuring. If the cargo is on a pallet, shoot the front face from 1–2 metres away.
How is CBM calculated?
CBM (cubic metres) = Length × Width × Height in metres. For example, a box measured at 600 mm × 400 mm × 300 mm is 0.6 × 0.4 × 0.3 = 0.072 CBM. Freight is usually quoted per CBM for LCL ocean and per kg (actual or volumetric, whichever is higher) for air and courier.
What is volumetric weight?
Volumetric weight (also called dimensional weight) is a pricing technique used by airlines and couriers to account for bulky, lightweight cargo. Ocean LCL freight uses 1 CBM = 1,000 kg. Air freight uses 1 CBM = 167 kg (the IATA standard). Couriers typically use 1 CBM = 200 kg (5,000 cm³ per kg). The carrier charges whichever is higher — actual weight or volumetric weight.
Can I use this for multiple boxes?
The tool measures one box at a time. For a shipment with multiple different box sizes, measure each size separately and multiply the CBM by the number of boxes of that size. Most LCL quotes are based on total CBM and total actual weight, so add all box volumes and weights before approaching a freight forwarder.
