On UK to UK deliveries weights and dimensions are not critical, provided that your parcel is no longer than 1m or no heavier than 20kg.
Some services have lower weight restrictions so please check the service description before placing your order.
If you do not know the weights and dimensions:
Weigh yourself on the bathroom scales with and without the parcel then calculate the difference.
Check out a similar item on eBay (weights and dimensions are often given on the description).
Please be aware that the weight and dimensions entered need to include the packaging.
We strongly recommend that when entering weights and dimensions, that they are as accurate as possible. This is to ensure that you avoid further charges and any possible delivery delays.
