Size and Weight Allowances
Understanding how Send My Bag® calculates your quote based on the size and weight of your item
Send My Bag® quotes are based on both the size and weight of your item. When our quick quote tool displays a price based on weight, for example quoting £30 for a 30kg suitcase, there is also a maximum size associated with that quote.
How to calculate your items weight band
Measuring your items
When measuring your item, this should be done from the widest points from side to side (width), top to bottom (length) and front to back (height), including any wheels or handles. Should you enter the dimensions in a different order, this is not a problem as the final volume will still be the same. 
Calculating the volume of your item
To calculate the volume of your item, simply multiply the three dimensions, for example 45cm x 45cm x 45cm = 91,125cm³. This item would fit within our up to 20kgs, 25kgs or 30kgs weight bands with no additional charges.
Size/Volume Allowances Per Weight Band are:
Weight Band Max Volume
Up to 5kgs 25,000 cm³
Up to 11kgs 55,000 cm³
Up to 15kgs 75,000 cm³
Up to 20kgs 100,000 cm³
Up to 22kgs 110,000 cm³
Up to 24kgs 120,000 cm³
Up to 25kgs 125,000 cm³
Up to 30kgs 150,000 cm³
Up to 34kgs 170,000 cm³
Maximum weight and sizes allowance for International services is 70kg / 350,000cm³.
How we charge for extra weight and volume
If your items exceeds the weight or size allowance of a lower band, your item will be moved to the next band available on that service, e.g. moved from the up to 15kg rate to the up to 30kg rate.
If you exceed the weight allowance of the upper band you will be charged in additional 5kg weight bands (rates vary by route).
If your item's volume exceeds the allowance of the upper band, you will be charged in additional 5kg / 25000 cm³ bands (rates vary by route).

All Services
This page is provided for general information purposes only, as oversize fees vary by route and service, when sending an item with a side of 117cm / 46 inches or more we recommend proceeding to step 1 of the order process and entering the dimensions of the items you are sending to receive a tailored quote.
Oversize fees are in place because bags of this size cannot move through the network on standard conveyor belts and cost considerably more to handle. Send My Bag makes no profit on these fees and charges at cost.
Suitcases often have their internal size quoted in litres, when entering dimensions please ensure you use the full external dimensions.
