How to Save Money by Correctly Measuring Your Parcel

23rd January 2023, 12:12am in Shipping Advice by Laura Hurtado Isalt

One of the most vital steps in the shipping process is measuring your parcel accurately.

Getting the dimensions and weight of your parcel right determines the correct shipping cost and ensures your package is delivered safely. It also helps you avoid any extra charges if the measurements don’t add up with the courier service you’re using.

Thankfully, the steps to measure your parcel are pretty simple. Whether you’re shipping your first package or need a refresher, use this guide to help minimise your shipping costs.

Collect Your Tools

Before you do anything, you should gather all the equipment you need to measure your parcel. Be sure to have the following:

  • A ruler, tape measure, or another device that displays numbers clearly so you can measure your parcel's length, width, and height.
  • A scale to weigh your parcel. There are several types available. Choose the most appropriate for your needs and ensure it’s calibrated correctly.
  • A calculator. Just in case you need to convert any measurements into different formats. You’ll need kilograms for weight and centimetres for width, height and length when you ship with Interparcel.
  • Having a pen and paper handy to record your measurements and calculations is always a good idea.

Measure the Dimensions of Your Parcel

Once you have everything you need, it's time to get the dimensions of your parcel. If you are the sender, here are some tips to use when measuring your parcel. If you only book the delivery and don't pack the parcel, please make sure your team is also aware of these details to avoid extra charges.

  1. Make sure to perform this task after you’ve packed everything and it’s ready for delivery, as the shape can change. Especially if it’s a satchel that isn’t padded appropriately. Mailers
    If you are using a box, Interparcel recommends a plain double-wall carton box for the best results.

  3. You should always avoid overfilling any type of package. It ensures the box you are using maintains its original shape and doesn't warp, which can impact the measurements.

  5. Remember, courier machines generally don’t have any human intervention. So it will always measure the largest dimension of each axis regardless of whether it’s part of the box. Make sure your parcel doesn’t have any loose ends and is not oversealed. As this could result in tape sticking out which will alter the measurements you originally declared!

  7. Always round up one to two centimetres for your parcel when inputting the dimensions. When your package is placed on the automated conveyor system, it can bump into other boxes and warp the shape. This can affect the original measurements.

  9. A slight discrepancy can add up and impact the final shipping cost. It can also result in your package being lost, damaged or delayed.

  10. A pro tip is to place the box against a wall to record the width, length and height. It will give you the most accurate reading.

  13. Take photos of the dimensions you’ve collected before the courier arrives. You can use these if there are any disputes concerning the measurements of the box.

Weigh Your Parcel

Now it’s time to weigh your parcel. There are several methods you can use depending on the scale you have.

If you are using a digital scale, record the weight accurately and round up to the next kilogram. Never round down, as this will affect your shipping rates.

You may need to use a different method for other types of scales. Follow the instructions provided with your device to determine the best technique for weighing your parcel. Getting an accurate reading is vital to ensure you are charged the correct shipping cost.

Calculate the Volumetric Weight

In addition to the actual kilograms of your parcel, your shipping carrier may also calculate the volumetric weight of your box when finalising shipping costs. It is the space that a package occupies in relation to its weight.

To work out the volumetric weight of your parcel, you will need to use this formula.

Volumetric weight formula

Multiply the length, width, and height
and then divide the result by the dimensional weight divisor.


You can use this formula to work out the volumetric weight. In some cases, this figure may determine the final shipping cost instead of the parcel's actual dead weight.
