Factors To Consider When Choosing the Size and Shape of Your Postcards

Available Space

Before you can choose the size of your postcard, you will need to finalise its message and confirm the word count. Paragraphs should ideally be kept short, with sufficient white space to break up blocks of text. Overlaying your text on various postcard sizes can provide you with greater insight into the right option.

Postcards that are too small for their design tend to look crowded and overwhelming to the reader. However, postcards that are the perfect size can improve the readability of your message and help capture the interest of its receiver.

Cost of Sending Postcards

Unlike many other promotional materials, the cost of advertising with postcards can include other expenses outside production.

If you want to send your postcards via post, you will also have to factor in the cost of sending postcards in Australia, which is an ongoing expense. Individual domestic stamps with Australia Post can cost between 60 cents and $1.10.

Design and Readability

Nobody wants to receive a postcard that resembles a page ripped out of a textbook. The most effective postcards are personable, eye-catching and unique. They incorporate vibrant images, graphics or colours and contain short but punchy text. Experiment with striking colour combinations, intriguing graphics and high definition photographs that reflect the postcard’s message.

The font that you choose will also help bring both sides of the postcard together. Handwritten typography is a powerful option for personalised messages, while sans serif fonts can infuse your words with a crisp, modern tone.

Not all unfolded cards are postcards

Forget what you think you know about unfolded cards. Unlike the traditional postcards found in souvenir shops, unfolded cards come in a wide range of sizes, shapes and styles. Their versatility makes them an effortless marketing tool that can be used for almost any application.

Invite guests to functions and conferences with a large A5 card that provides plenty of space for extra information. Need to fill up your business’s display rack? Choose a DL card to create vouchers or product lists that customers can take home with them as a physical reminder of your business. However you intend to use your cards, one thing is for certain: there are no rules when it comes to advertising with unfolded cards.
