Paper Size Guide for Australian Weddings

Q: What size are wedding invitations in Australia?

A very common size for wedding invitations in Australia is 5"x7" (127x178 mm) . It has a balanced, elegant feel and fits standard envelopes without attracting higher postage costs. Some couples also use A5 or A6, but 5"x7" is the preferred modern choice.

Q: Is 5"x7" the standard size for wedding invitations in Australia?

It’s not the “official” standard, but 5"x7" (127x178 mm) is the most commonly used invitation size in the Australian wedding industry. It looks refined, fits common envelopes, and avoids the bulky feeling (and higher postage) of A5.

Q: What size should RSVP cards be for Australian weddings?

Most RSVP cards are either A6 (105x148 mm) or A7 (74x105 mm) . They pair well with 5"x7" invitations and fit neatly inside standard envelopes.

Q: What is the difference between A4 and US Letter for printing?

A4 is 210 x 297 mm and is Australia’s default paper size. US Letter is 8.5" x 11" , slightly wider and shorter. Because Australian printers and envelopes are aligned to A-series sizing, US Letter templates can cause scaling, trimming and fit issues. Australian-friendly templates are always easier to work with.

Q: Which paper size is most cost-effective for wedding invitations in Australia?

If you’re focusing on postage and envelope costs, 5"x7" is the best balance of premium look and practicality. If you want the most economical option overall, A6 is the cheapest to print and post. A5 tends to be the most expensive because of envelope size and weight.

If you’re planning a wedding in Australia or using digital stationery templates, it helps to know which paper sizes work best. This guide breaks down the common A-series sizes used here and how they fit into modern wedding stationery, plus the popular 5″x7″ invitation size used across the industry. Understanding these formats makes choosing, printing and assembling your stationery much easier, especially when you’re working with a mix of menus, signs, cards and invitations.

When your stationery follows standard Australian sizes, the printing process becomes much more smoother. Using the right dimensions means your designs fit envelopes properly, print shops can process your files without adjustment, and your suite looks cohesive from start to finish. Whether you’re creating everything yourself or customising a template, knowing these paper sizes saves time, stress and a surprising amount of trial and error.

Understanding A-Series Paper Sizes in Australia

Australia uses the ISO A-series system, which scales neatly from large to small. These are the sizes you’ll see most often when working with invitations, menus, signage and printables.

An illustrated diagram of the ISO A-series standard paper sizes for wedding stationery.

A1 (594 x 841 mm)

A1 is the second largest paper size in the ISO A-series standard and considered poster size.

Ideal for:

Welcome signs
Seating charts
Order of events signs

A4 (210 x 297 mm)

A4 is the everyday paper size and the easiest to print at home.

Ideal for:

Home printing
Table signs
Templates that can be trimmed down

A5 (148 x 210 mm)

A5 is half an A4 sheet and prints easily, though it can feel a bit large for invitations. A5 fits easily into standard C5 envelopes.

Ideal for:

Ceremony programs
Menu cards
Small signs

A6 (105 x 148 mm)

A6 is the most popular small invitation size in Australia and is closest to 4″x6″ (which is photo size). It also fits readily into standard C6 envelopes.

Ideal for:

Save the date cards
RSVP cards
Details cards
Thank you cards

DL (99 x 210 mm)

DL is a long, narrow format often used in Australia for menus, bar lists, and signage that needs a tall, elegant shape. It’s one of the most versatile event sizes because it fits easily onto tables without taking up space and looks refined in photos.

Ideal for:

Menus
Bar menus
Table numbers (tall format)
Wedding programs

DL prints easily on A4 (you get three per sheet), making it cost-effective and straightforward for both home printing and professional printers. The proportions suit modern, minimalist design styles and work beautifully with simple typography.

The Popular 5″×7″ Wedding Invitation Size

Although Australia uses A-series sizing, 5″×7″ (127×178 mm) has become the standard for wedding invitations. It balances beautifully in the hand, fits common envelopes, and feels refined without being oversized.

Why it’s widely used:

It looks timeless and elegant
It isn’t as bulky as A5
It fits readily available invitation-sized envelopes
It avoids the higher postage costs of larger formats

All of our wedding invitation templates follow this size for a reason — it’s the most practical and aesthetically pleasing option for modern weddings.

Australia vs US Paper Sizes

Templates from US websites and Etsy sellers often use US paper sizing which is measured in inches.
This size doesn’t align with Australian envelopes, printers or frames, so it’s easier to use A-series or 5″x7″ templates made for local standards. You can view the full A-series chart at papersizes.io.

Most Australian printers prefer PDF files
Export with 3 mm bleed when possible
5″×7″ remains the ideal invitation size for both design balance and postage
