Choosing the right leaflet size is an important part of creating effective printed marketing. The size you choose can affect how much information you can include, how easy the leaflet is to handle and, ultimately, how your message is presented. At Dynamic Print in Norwich, Norfolk, we print leaflets in a wide range of sizes, formats and paper stocks, from simple promotional flyers to premium folded brochures and bespoke marketing pieces. So, what size should your leaflet be? For most promotional campaigns, A5 is one of the most popular leaflet sizes in the UK. However, A4, A6 and DL are also widely used, depending on the amount of information you need to communicate and how the leaflet will be distributed.
Popular Leaflet Sizes in the UK
A4 Leaflets – 210 × 297mm A4 is a good choice when you have a lot of information to communicate. It provides plenty of space for photographs, text, diagrams, product information or pricing and is often used for:
- Company information
- Product brochures
- Menus
- Event information
- Detailed promotional material
- Information sheets
A4 can also be folded to create smaller finished formats, making it a versatile option for printed marketing.
A5 Leaflets – 148 × 210mm A5 is one of the most popular choices for leaflet printing. It offers a good balance between space and portability, making it particularly effective for promotional campaigns, events, retail marketing and direct mail. A5 leaflets are commonly used for:
- Business promotions
- Events and exhibitions
- Restaurant and takeaway promotions
- Charity campaigns
- Product launches
- Local marketing
- Wedding and event stationery
If you’re unsure what size leaflet to choose, A5 is often a good starting point.
A6 Leaflets – 105 × 148mm A6 is a compact format that works particularly well when you need a simple message that is quick to read. A6 leaflets are often used for:
- Promotional offers
- Postcards
- Event promotions
- Save the dates
- Appointment cards
- Small promotional campaigns
Because A6 is compact, it can also be an economical choice when you don’t need a large amount of space. DL Leaflets – 99 × 210mm DL is another very popular UK print size, particularly for mailshots and promotional material. Its long, narrow format makes it easy to handle and ideal for fitting inside a standard DL envelope. DL leaflets are often used for:
- Direct mail
- Menus
- Price lists
- Promotional offers
- Event information
- Business introductions
Which Leaflet Size Should I Choose?
The right size depends on what you want your leaflet to achieve.
Choose A4 if: you have a lot of information, photographs or products to showcase.
Choose A5 if: you want an effective all-round promotional leaflet with enough space for information without being too large.
Choose A6 if: you want something compact and easy to distribute.
Choose DL if: your leaflet is being mailed, inserted into an envelope or you prefer a long, narrow format.
There is no single “best” leaflet size. The right choice depends on your content, audience, distribution method and budget.
What About Folded Leaflets?
Your finished leaflet doesn’t have to be a single flat sheet. Folding can create additional panels and give your printed marketing a more structured and professional appearance. For example, an A4 sheet can be folded to create a smaller finished piece, while an A3 sheet can be folded down to A4. Common folding styles include:
- Half fold
- Tri-fold
- Roll fold
- Gate fold
- Concertina fold
If you’re considering a folded leaflet, it is important to allow for the fold positions when preparing your artwork. At Dynamic Print, we can advise you on the most suitable finished size and folding method for your project.
What Is SRA Paper?
You may also come across SRA paper sizes when discussing your leaflet with a printer. SRA stands for Supplementary Raw Format. These sheets are slightly larger than the corresponding A-series sizes, giving the printer additional room for trimming and bleed. For example:
SRA3 – 320 × 450mm
This is a commonly used sheet size in professional printing and is particularly useful when producing smaller finished formats such as A4 and A5. The important thing to remember is that SRA is generally a printer’s sheet size rather than the finished size of your leaflet.
What Is Bleed and Why Does My Leaflet Need It?
If your design has colour, photographs or graphics running right to the edge of the leaflet, you will normally need to include bleed in your artwork. Bleed provides a small area beyond the finished trim size. This allows the printer to trim the sheet accurately without leaving unwanted white edges. For example, if you are designing an A5 leaflet, the finished size is 148 × 210mm, but your artwork will normally need to be supplied slightly larger to allow for trimming and bleed. If you’re unsure about preparing your artwork, speak to us before sending your files. Or check out our blog for sending files with bleed here.
A-Series Paper Sizes
The A-series is based on the international ISO 216 paper-size standard. Each size is approximately half the area of the previous size. Some of the most commonly used sizes are:
- A0: 841 × 1189mm
- A1: 594 × 841mm
- A2: 420 × 594mm
- A3: 297 × 420mm
- A4: 210 × 297mm
- A5: 148 × 210mm
- A6: 105 × 148mm
- A7: 74 × 105mm
For most everyday leaflet printing, A4, A5 and A6 are the sizes you’re most likely to consider.
Can My Leaflet Be a Bespoke Size?
Absolutely. Although standard sizes are popular because they are familiar and can be cost-effective to produce, there is no reason your printed marketing has to look like everyone else’s. At Dynamic Print, we can produce bespoke printed pieces using different paper stocks, finishes and traditional print techniques. For businesses looking for something more distinctive, options can include:
- Premium papers
- Hot foiling
- Embossing
- Blind debossing
- Die cutting
- Specialty and sustainable papers
A carefully chosen paper stock and finishing process can turn a simple leaflet into something that people want to keep rather than throw away.
What Paper Should I Use for My Leaflet?
The paper you choose is just as important as the size. A lightweight stock may be suitable for high-volume promotional distribution, while a heavier or more tactile paper can give a premium feel. At Dynamic Print, we also offer a range of unusual and sustainable paper stocks, including recycled and speciality papers, which can help businesses create printed marketing that reflects their brand values. If your leaflet is intended to make a strong impression, we can help you choose a paper and finishing combination that suits your design and budget.
