Flyers are single-sheet ads that allow you to reach a targeted audience at minimal cost.
And they’re incredibly effective. In fact, according to the Data Marketing Association, flyers are the most memorable form of advertising, with 89% of people saying they remember its message.
This explains why flyers are used for event promotion, product launches, and to raise awareness about a cause or fundraiser.

A4 (8.3″ x 11.7″ or 210mm x 297mm)
A4 flyers are great when you need to incorporate charts, graphs, or infographics to explain a product or service. These flyers are handy in business presentations, brochures (when folded neatly), and white papers.
For example, this flyer is uses text and visuals to explore animal behavior. It’d be a great fit in classrooms or the office lunch room to lighten up the mood.
US Letter (8.5″ x 11″ or 216mm x 279mm)
A US letter flyer is similar to an A4, but slightly bigger. Like the name suggests, this size is used in North America to make flyers and inserts.
US letter size is a great option when you need extra space for text and visuals but still want to have a flyer that’s easy to distribute.
Besides their use as inserts in newspapers, magazines, or brochures US Letter size flyers are great for promoting an event, advertising a sale, or spreading the word about your business.
A5 (5.8″ x 8.3″ or 148mm x 210mm)
A5 flyers hit the sweet spot between portability and impact which makes them perfect when you need to announce promotions and/or new products.
Not only is their size ideal to capture attention at takeaway spots or events, they can transform into rack cards (when printed double-sided).
This bridal shower A5 flyer conveys essential information without taking up too much space.
Half-page (8.5″ x 5.5″ or 216mm x 140mm)
Half-page flyers are perfect for creating coupons, announcing offers, and creating event invites because they can fit into envelopes and be sent to a target audience or left at reception counters.
This half-page flyer is compact and can be placed in a bar where potential customers will see it.
Postcard (4″ x 6″ or 105mm x 148mm):
Postcard flyers are small enough to be displayed at checkout counters, information desks, or promotional stands in stores.
Besides marketing, postcard flyers can be used as invitations, announcements, or as souvenir items.
This postcard flyer can be used in direct mail campaigns, handed out at events, or left in public spaces for broad distribution.
Rack cards (3.5″ x 8.5″ or 89mm x 216mm):
Rack cards are generally added as inserts in brochures or displayed events or stores.
They’re used to promote a business, products, or events. Other unique use cases include their ability to share valuable information, share special offers, or be used as mini-menus for restaurants or cafes.
Understanding flyer measurements
So far, I’ve presented flyer measurements in two sizes: inches and millimeters.
This is because North America (US and Canada) typically use inches to define flyer size while Europe and other regions rely on millimeters (e.g., 210mm x 297mm).
How to choose the right flyer size for your needs
Choosing a flyer size depends on your needs. For example, if you’re looking for a design that fits into a mailbox, you’ll probably want to skip the A4 format and go for a half-page or A5 flyer.
Key factors to consider when choosing the right flyer size
Here’s what you need to consider when finalizing flyer size:
- Target audience
How will your audience consume the flyer (hand out, in mail, or on a rack)?
Other factors to consider about audience include age. For example, an older audience might benefit from larger flyers that feature bigger fonts.
- Content and design
How much information do you need to convey? If you need to communicate complex information, you’ll want to select a larger flyer size.
- Budget
Larger flyers are more expensive to print and mail. If you don’t have the budget, you’ll want to go with cost-effective alternatives like a half-page.
Design considerations for different flyer sizes
Flyer design influences effectiveness of your message and since there is no one rule fits all formula, let’s review some basic design considerations for each flyer type.
A4/US Letter
Since these flyers are large, make sure there is a clear information hierarchy to maximize readability.
To achieve this, use headings, subheadings, and bullet points to guide the reader’s eye and use white space to prevent information overload.
Here’s a great example of an A4 flyer that uses subheadings to separate information into different sections (there’s also ample white space between the text).
A5/Half-Page
Since space is limited on A5 and half-page flyers, get creative and make most of the real estate.
Make sure these flyers have a clear call-to-action and use bold fonts and contrasting colors if needed.
If you need more space to share message across, you can add a QR code that allows people to read more about your offer or service elsewhere.

Postcards
In postcards, your message needs to be concise and in large, easy-to-read fonts so the content is easy to understand. However, visuals are the highlight here, so choose eye-catching images or graphics to draw viewers in.
Here’s a postcard that caught my attention almost immediately.
Rack cards
Rack cards have a vertical display to fit racks, so make sure to design top to bottom.
Start with a captivating headline to spark interest or offer something enticing that compels viewers to pick up your rack card to learn more.
Since space is limited in these flyers, prioritize readability with contrasting colors and bold fonts that makes your message stand out from the competition.
Conclusion: Find the right flyer size for your needs on Venngage and achieve your objectives
The right flyer size can make or break your marketing campaign. Imagine a large flyer filled with tiny text and a single, blurry image. It wouldn’t be very effective, would it?
To maximize impact, you need to choose a flyer size based on your content, audience, and budget.
