The best and most accurate way to check an item’s weight is of course, to weigh it using scales – but if you find yourself needing to get an idea of an item’s weight and find yourself without any gadgets to assist, it can be helpful to use household or commonplace items to calculate an approximate weight of your parcel. This is not an exact science, but it can help you to estimate the weight and size of your parcel in order to get an idea of how much it will cost to send.

When you come to book your parcel delivery, it is important to provide an accurate weight and measurement. If you under-declare the weight or size in your booking, you risk the collection being refused or the parcel getting returned back to you.

How to weigh your parcel


If you're likely to be sending items regularly through the post, it's a good idea to invest in a pair of scales. Even a basic set will be accurate enough for postage purposes without having to break the bank – with many options available from high street retailers and online marketplaces for around £10 – a quick Google search will show you what’s available.

If you are sending a small parcel then your kitchen scales will work perfectly. For large or awkwardly shaped parcels, we recommend using your bathroom scales instead. Weigh yourself holding the parcel and then again without the parcel – deduct the second weight from the first to find out the weight of your parcel. Remember to always make sure you weigh your parcel in metric – that’s grams / kilograms.


Don't have scales to hand?


We collect and deliver countless parcels every day of all sorts of size, weight and value, so we couldn’t possibly list them all here, but to give you an idea of some of the more commonly sent items with their approximate weight, here’s a handy table:

Our weighing life hacks


If you’re struggling to find scales to weigh your parcel try feeling the weight of your parcel against everyday household items.

If you’re sending heavier items, did you know that 2 litres of fluid weighs roughly the same as 2kg? That's another way to calculate the weight of your parcel.



Need more help? Handy comparisons in the cupboard


Ordinary things in the cupboard are useful as they’re mostly sold by weight; a bag of sugar or flour, tin of beans or tomatoes or a packet of crisps or sweets are all labelled in grams / kilos and can allow you estimate how much your items weigh. For example:

  • A standard packet of crisps weighs 25g, which is roughly about the same as a silver ring or lightweight sweater.
  • A regular can of baked beans or tinned tomatoes weigh around 400g - 440g which is about the same as a sweater.
  • A 1k bag of sugar weighs around the same amount as a lightweight laptop or tablet. 


Take into account packaging weight


Remember the packaging you send your items in will add to the overall weight of your parcel so please take this in to account.

Fairly light in weight, padded envelopes are ideal for sending items such as DVDs, brochures or smaller items such as costume jewellery or gifts. Cardboard boxes will protect your items better, but will weigh more. As a guide, see below for some approximate weights of envelopes and small boxes for posting.

  • An empty, standard shoebox weighs around 200g
  • A small empty box with dimensions of 18 x 11 x 6 cm weighs around 15g
  • A C4 paper envelope weighs around 25g
  • An A4 bubble padded envelope is around 25g

In addition you'll need to factor in the padding you'll need to pack around your items such as bubble wrap or air pockets.


Measuring your parcel


It’s important to understand that not only the weight of your parcel affects the price you’ll pay to ship a parcel across the UK or abroad, but also the dimensions of the parcel. So as well as weighing it, make sure you measure your parcel to get the cheapest delivery rates available for the item.

Use a ruler to measure the width, length and height of your parcel in metric – that’s mm / cm. If you are sending a large parcel, you may need to use tape measure instead.



No ruler? No problem!


If you’re struggling to find a ruler or a tape measure to measure your parcel, use our paper measurements to ensure you get the dimensions correct.
