When Do You Need a Brochure?
Before diving right into brochure and flyer sizes, it is important to consider the differences between brochures and flyers. Let’s say you run a corporate business! If you want to market your brand to the target audience, you should know which one to use.
A brochure serves better if your business wants to convey more information about your service or product. Talking about its design, the brochure has folds, while the flyer does not. Though you can fold a flyer. But fold is not part of the flyer’s design.
Brochures have different types of folds that reflect different feels. So you can fold a brochure in many different ways. Keep in mind, the best brochure fold depends on its size and design. Here are the commonly used fold types of brochure:

Explore Standard Sizes of Brochures
Wondering how big or small a brochure is? Well, there are multiple types of standard sizes for brochures. Consider the most common sizes for brochures, whether folded or opened:
- Letter size: 21.59 x 27.94 cm
- DIN A4: 21.0 x 29.7 cm
- Legal size: 21.6 x 35.6 cm
- Memo size: 14 x 21.6 cm
- Tabloid size: 28 x 43.2 cm
Out of the above sizes, letter-size paper is the most common. This paper has a half-fold and tri-fold style. If you print a tri-fold brochure on the same standard letter-size paper, each side will measure 21.59 x 27.94 cm. However, this brochure will have dimensions 21.59 x 9.4 cm after you fold the paper.
And when each side of a half-fold brochure is printed on standard letter-size paper, it will measure 21.59 x 14 cm after folding.
When Do You Need a Flyer?
Flyers come into use when your business has little information to convey. It is suitable to use when you need to announce a sale, an upcoming event, and your business launch. You can also leverage flyers to get the conversation between you and your customers with a fact sheet about your product.
Plus, a flyer is used to advertise you, what you do, and what you are promoting at the moment. Use flyers to announce grand openings, seasonal deals, community involvement, and job openings. Or to provide discount vouchers, ensuring they have a clear headline, concise info, and a strong call-to-action.
Explore Standard Sizes and Uses of Flyers
The standard size of a flyer is the same as a piece of computer paper. Its size is very similar to the universal A4 size, that is, 21 x 29.7 cm. However, flyers are popular due to the smaller format sizes, like:
- Letter size: 22 x 28 cm

When to Choose a Brochure Over a Flyer?

Going with printing a brochure will be suitable when you have to nurture on connections you have already made.

Factors to Consider in Flyer and Brochure Design
The size and design of your flyers or brochures must align with their purpose. To understand this purpose, consider the following key factors:

Distribution Method
For bulletin boards, your flyers must be larger for maximum visibility. For mailing, your brochures must need to fit the dimensions of a standard envelope. For posting invitations, pick a DL-sized flyer or a tri-fold brochure, ensuring they fit snugly in standard envelopes.
Content Volume
Want to convey concise messages? Fyers are best. But in the case of providing in-depth information. Brochures are perfect. For example, if you run a luxury spa, then you should choose a brochure to incorporate sections on services, pricing, and client testimonials.

Brochure and flyer sizes vary. But common sizes are Letter (8.5"x11") and Half-Letter (5.5"x8.5"). However, international standards use A4 (210x297mm) and A5 (148x210mm), with DL (99x210mm) popular for mailers.
Australian flyers come in standard A-series sizes like A4, A5, A6, and the popular DL (one-third A4). The dimensions vary from small, hand-out sizes like A6 (105x148mm) to larger ones for posters like A3 (297x420mm).
The most recommended flyer sizes are the standard US Letter (8.5" x 11") and the international A4 (8.3" x 11.7") for versatility. But smaller sizes like A5 (5.8" x 8.3") or Half Sheet (8.5" x 5.5") are great for direct mail or coupons.
Neither A5 nor A6 is inherently better. It depends on your goals. For example, A6 (postcard size) is great for quick, high-volume handouts, direct mail, or simple coupons due to its portability and lower cost. However, A5 size offers more space for detailed info, images, menus, or event schedules, making it ideal for something to be kept longer or displayed.
