When sending your parcel, it's important that it meets the size guidelines: Parcel sizes. With some services there are restrictions on the maximum allowed which is calculated with the Overall Size.
How to calculate overall size: Take the two shortest sides of your parcel and sum them. Multiply the sum by 2 and finally add the length. The total is the overall size.
- Add together the 2 shortest sides: 40 + 50 = 90.
- Multiply this number by 2: 90 x 2 = 180.
- Add the longest length to this number: 180 + 55 = 235.
The overall is in this case 235 cm.
