How to calculate the weight of your parcel without scales

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, it can be helpful to use household or commonplace items to calculate an approximate weight of your parcel. While not an exact science, it can help you to estimate the cost of sending a parcel until you’re able to weigh and measure it properly.

While this guide can help you get a ballpark weight and size for your items, it's far better to be as precise as possible – using scales and a ruler will ensure you avoid a parcel being held at one of our depots or being returned to you, due to under declaring the weight or size.

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.

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 guesstimate how much your items weigh.

For example:

  • A standard packet of crisps weighs 25g, which is roughly about the same as a small silver ring or lightweight necklace
     
  • A regular can of baked beans or tinned tomatoes weigh around 400 - 440g which is about the same as a sweater
     
  • Hunt around for any pre-packed unused items you have in the house; a 250g packet of noodles, a 500g packet of pasta, a 750g bag of rice, a 1kg bag of sugar, a 1.5kg bag of flour can be useful comparisons for weight.

Rough weights of popular items

ipostparcels 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, please see below:

  • A single DVD in a case weighs around 100g
     
  • A mid-sized teddy bear weighs approx. 400g
     
  • Footwear - for e.g. a pair of size 10 men’s trainers approx. 800 - 900g or size 5 women’s approx. 300 – 400g
     
  • Jeans – it will depend on the size and gauge of denim, but an average size and mid weight pair of ladies jeans weighs approx. 450g while men’s will weigh around 700g
     
  • Books  - there will be great variation from one to another but generally speaking; a 100 page glossy magazine weighs approx. 250g, a 400 page paperback is approx. 300g and a 400 page hardback approx. 700g

Taking 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.

Setting up a business? We recommend weighing each of the different size envelopes and boxes and taking a note of their weight. Then you can calculate this easily into your shipping costs on your website or eBay shop.

How to measure your parcel without a ruler

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.

As with use of scales for weight, we always advise you measure your parcel correctly using a ruler to get the most accurate price, however, if you don’t have a ruler to hand, take a look below to help you get it right by using an ipostparcels #LifeHack

Step 1 - measuring

Always measure the length, width and height of your parcel in metric – that’s mm / cm

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.

Alternatively, we have measured some handy household items that will be able to help you when it comes to sizing up your parcel.  


 

Step 2 – weighing

Always make sure you weigh your parcel in metric – that’s grams / kilograms.

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? This handy ipostparcels #LifeHack should help you when it comes to getting the weight of your parcel correct. 


So remember, in parcel delivery, size and weight matters!
