You must select an envelope weight that best fits your requirements and budget. The costs depend on how much the overall envelope weighs after you stuff it with your contents.

This blog discusses the Australia Post standard envelope weight and how you can manage your postage rates.

Let’s dive in!

How Much Do Envelopes Weigh?

#10 envelopes weigh 6.75 g—which is the base weight you can use for comparison with other envelope types. The weight limits range to 500 g to allow you to select according to your mailing purpose.

For instance, you can use thicker packaging going up to 200 to 400 g as the max weight for envelope to send marketing mailers. They impact your audience positively and depict that you have put adequate effort and thought into the items.

Marketers prefer using the envelope max weight to differentiate themselves from their competitors. Using these envelopes can help them get more attention and responses.

They have several options to make their envelopes more unique, but it can increase the weight further. For example, adding clasps, buttons, etc., to envelopes may give an appealing look to them.

But does Australia Post allow using such features for your mailings? No!

You must follow the Australia Post standard envelope weight and mail preparation guidelines to avoid paying hefty surcharges on shipping. If you want your mailers to look good, you can use techniques like

Embossing.
Using colourful envelopes.
Adding teasers.
Printing eye-catching graphics, etc.

Transactional mail works differently and does not demand the use of heavier envelopes. It includes invoices, statements, bills, reports, contracts, forms, etc., requiring the standard envelope weight of 6.75 g.

Companies send such mailings to already existing customers regarding a transaction. This audience is already familiar with the business and expects to receive mail from them. Thus, they can skip using fancy items of the envelope max weight as they do while sending promotional materials.

What Is the Australia Post Standard Envelope Weight?

Before we get into the weight of a standard envelope, let us discuss what qualifies as a letter to Australia Post. You may need to send the other items as parcels and pay extra postage.

A letter must:

Weigh no more than 500 g.
Have a maximum thickness of 20 mm.
Consist of flexible contents only (if being sent domestically).
Not be broader than 260 x 360 x 20 mm envelope (B4 size).
Only carry printed material with zero commercial value (sending overseas).
Be rectangular.

Australia Post ensures that mailers focus on the weight of a letter envelope and several other aspects to ship the item smoothly. If you don’t fulfil one or more of these requirements, you may need to send the mailers as parcels.

Here are the limits for the max weight for envelope and size for domestic and international shipments for your reference:

Mailing Location	Size	Max Weight for Envelope	Max Dimensions	Max Thickness
Domestic and International	Small envelope	250 g	130 mm x 240 mm	5 mm
Domestic and International	Large envelope	500 g	260 mm x 360 mm	20 mm

Avoid stuffing your envelopes with pens, pen drives, clips, etc., as they can damage the postal equipment during mail processing. These items might also damage your materials, and you cannot claim a refund for such cases. It is also why Australia Post has a standard envelope weight limit—to fit the mailers in the sorting machines and speed up the delivery process.
