Sizes and weights

Understand how to choose the right size for your parcel, and how the shipping cost is calculated. Below is all of the information you need to master the booking process.

Size Options

Sendle has 1 satchel size, and 4 box or satchel sizes available. Each size has both a weight and cubic volume limit. You must choose a size that fits both the weight and volume under the limit.

  • Satchel - up to 500g and 2L (more information here)
  • Shoebox - up to 2kg and 8L
  • Briefcase - up to 5kg and 20L
  • Carry-on - up to 10kg and 40L
  • Check-in - up to 25kg and 100L

If you are a business sending a large volume of parcels, we've got a way for you to access 1kg and 3kg rates as well. For more information, get in touch with our business team here

If you’re unsure what size your parcel is, use the dimensions calculator (example below).

Maximums

  • The longest side of any parcel cannot be bigger than 1.2m (120cm).
  • The largest volume for any parcel is 100L.
  • The heaviest weight for any parcel is 25kg.

Can I just use the weight or the volume?

 - No. You must choose the size that fits BOTH the weight and volume under the limit.

Examples

Both of these fit under the weight and volume limit for a 5kg and 20L Briefcase size parcel:

  • 10cm x 40cm x 50cm (20L) + 1kg.
  • 1cm x 40cm x 50cm (2L) + 5kg.

Neither of these parcels fit into the 5kg and 20L Briefcase size parcel. Either the weight or the volume exceeds the Briefcase limits:

  • 10cm x 40cm x 50cm (20L) + 9kg = Carry-on.
  • 100cm x 15cm x 20cm (30L) + 1kg = Carry-on.

Volume is calculated as a cube (like a box) in litres. Litres are calculated by multiplying the centimetre of the three dimensions in centimetres and dividing by one thousand (height X width X depth [all in cm] ➗ 1000).

Mailing tubes/cylinder shaped parcels

Mailing tubes, or any parcel that is cylinder-shaped, are charged on the same basis as with all parcels. That is, we need to consider both the weight (kg) and volume (L). To find the volume, we still want to treat it like we’re finding the volume of a box, only with diameters instead of width/height.

For a tube/cylinder, this would be (length x diameter x diameter) = Liters.

Here’s an example, a tube that is 100cm long, with a diameter of 12 cm is: (100x12x12cm)/ 1000 = 14.4L

Parcel restrictions
- in addition to the liter volume, the weight must also be considered when selecting the right size. For example, if the tube is 14.4L and it weighs under 5kg it must be booked as a Briefcase size (20L/5kg max)
- as with all parcels, they need to be under 100 L, under 25 kg and the length under 120 cm in order to be fit for Sendle
- also, take note of how your label fits on the tube. It’s very important that the parcel can scan correctly, otherwise the courier may reject the pick-up.

Now that you know how to figure out the size you can create an order for your parcel using our national flat rates and save a bunch on your delivery costs.
