We recommend using a measuring tape to measure any items sent as this is the most accurate way to measure items.
These can be purchased from most high street shops or supermarkets.
Alternatively, you can use rulers / A4 Pages (these are 30cm in length) to attempt to measure the suitcase however this is not as accurate as using a measuring tape.
Please ensure all of your items are measured, including any handles or wheels on suitcases and including any bulges on boxes. You need to measure the longest lengths on any side of an item as this will still take up space in the courier's network.
