Sendle’s Handy Parcel Size Guide

A delightful breakdown of our six parcel sizes & what they mean to you.

With just six parcel sizes to choose from, Sendle is a simple choice for parcel delivery. But, the sizes, bound by both volume and weight, can be hard to guesstimate for certain postal boxes.

Plus, volume can be difficult to visualize. Which is why we created this guide, as well as the handy calculator in your dashboard (seen handily below).

You want to make sure you are getting the biggest bang out of each volume break. What follows is a simple and fun handbook for all of our parcel sizes.



This one is enough for your small stuff. The size of an A4 sheet, you can fill it with up to 500 grams of fun (or boring) stuff.


Things you could ship under Satchel:

Five pairs of socks

Two Freddy Krueger masks

 A simple set of silver thumb rings

493 paperclips

Send what you want, where you want regardless of its subjective level of fun.

Or, you can remove all weight restrictions with our Unlimited Satchel.



Now, when what you’re sending is just a little heftier and more voluminous, you level up to the handbag. Enough space to throw in the essentials for a night on the town but maybe not great for a weekend away.

With a capacity of up to 1kg and 4L, this handbag can convey a decent quantity of merchandise, assuming you aren’t slinging bespoke shipping anchors.


Things you could ship under Handbag:

A pair of trousers

A pack of patterned undies

Just stick them in a little box (or mailing bag) and ship them out.

To get you started, we’ve included some of the more common boxes that are perfect handbag material. The highlighted ones come in with the volume closest to the max for this size.

Small packages



The shoebox is as apt a description as we could come up with here. Luckily, you are encouraged to send all types of things, not just those that encase your tootsies. With a ceiling of 3kg and 12L, we’re certain you can find a whole bunch of non-shoe things to ship.


Things you could ship under Shoebox:

Paperback series of The Hitchhiker’s Guide to the Galaxy

A warm blanket (for snuggling with a good book)

Below is a selection of the more common box sizes out there. The boxes that size out the closest to the max volume for this package are highlighted.

Small packages



While the name may sound a little stuffy, there’s no need to stuff this parcel with business documents or paper clips. While the sky isn’t the limit here, you can fill this one up with a fair amount of fine things. To be clear, the limit is up to 5kg and 20L.

Now, don’t go out, buy a briefcase, fill it with fun things, and slap a label on it. We’d recommend just using a box of a similar size (a few of which you will see below).


Things you could ship under Briefcase:

A light bowling ball

 Three bottles of Cabernet Sauvignon
*see packaging guidelines

Find a few fine boxes to use for any of these examples and more.

Small packages



The go-to size for all those travellers who have no time for baggage claim but still need to keep a small wardrobe with them.

When packing up a fair amount of stuff, know you can shove up to 10kg into a 40L box and call it a carry-on. 

Walk right past the baggage carousel.

Just don't actually send it in a carry-on bag. A box will work best.


Things you could ship under Carry-on:

A blender in there plus all the ingredients for your pina colada

Your whole outfit—shoes, shades, dress, earrings, a winter jacket, and a scrunchy

Again, to get as close to the max as possible, you’ll want to look at the highlighted boxes below.

Small packages



Now, we’ve all exceeded our carry-on capacity and had to opt for checking bags and waiting for the belt to convey our dear luggage. That’s OK. In the context of Sendle, it just means you’ve landed upon our largest size.

The upper limits of this box are a rather massive 25kg and 100L.

Remember, send your stuff in boxes. Actual luggage will not be accepted.


Things you could ship under Check-in:

543 golf balls

Half a dozen carefully cushioned garden gnomes

Below, you will find some box sizes that will fit the bill.
