Printing Options Available:

You have 3 printing options available: A4 size, Letter Size & A0 size. You can print our patterns at home if you have a printer or send them to the online/ local printing shop.

• Ensure you print at actual size (100%scale). Select “borderless printing”
  
• Verify that the print out size is correct by measuring the centimeter scale on any pattern
• Align all pages and tape them together using clear tape and cut out your size. The pattern already includes a 1cm seam allowance

Tip:

You can simply organize your patterns by printing the first page of the booklet and sticking it to A4 envelope. Fold the pattern pieces nicely and store them in the envelopes.

Explained: Difference Between A4, Letter Size, and A0 Size

Whether you're a beginner or an experienced sewist, you’ve likely asked yourself: What’s with all the different printing paper sizes when buying patterns? The answer is simpler than it seems—and it’s actually very important. The main difference? Paper size! Let’s dive into the details so you can choose the right one for your project.

1. What is A4 Size?

A4 is part of the A series of paper sizes, commonly used worldwide (except in North America). It's one of the most popular paper sizes for everyday printing, and it works just as well for sewing patterns, especially when you're working on smaller projects.

• Dimensions: A4 paper measures 210 mm x 297 mm (8.27 inches x 11.69 inches).
• Sewing Pattern Use: A4 is ideal for smaller patterns or when you need to print multiple pages that make up a larger pattern. For example, many downloadable sewing patterns (especially those for home printers) come in A4 format, allowing you to print the pieces one page at a time and assemble them afterward.

Pros of A4 for Sewing Patterns:

• Convenient for home printers.
• Instant download option: Unlike paper patterns, which you have to wait to receive, digital patterns are available instantly, letting you start your project within minutes!
• Compact and easy to store. (Pro tip: use A4-sized mailing envelopes to store your patterns!)
• Ideal for smaller sewing projects.

However, A4 can be a bit limiting for larger patterns, as you'll need to piece together multiple pages. But don’t worry—it’s definitely worth the effort! Check out my video on how to print and assemble A4 patterns.

2. What is Letter Size?

Letter size is the standard paper size used primarily in the United States and Canada. While it’s very similar to A4, there are slight differences in the dimensions that set it apart.

• Dimensions: Letter size measures 8.5 inches x 11 inches (215.9 mm x 279.4 mm).
• Sewing Pattern Use: Like A4, Letter size is often used for downloadable sewing patterns, particularly for home printers in the U.S. and Canada. Many patterns are formatted for this size, making it easy to print on a standard home printer. However, the small size difference from A4 can sometimes cause minor alignment issues if the pattern isn’t properly adjusted, so be sure to use the correct file.

Pros of Letter Size for Sewing Patterns:

1. Easy to find and use in North America.

2. Widely supported by home printers.

3. Great for small to medium-sized patterns and personal projects.

Considerations for Letter Size: Always make sure you print the right file! All my patterns are clearly labeled in the file name (e.g., pattern-name-A4-Size.pdf, pattern-name-Letter-Size.pdf, pattern-name-A0-Size.pdf) and on the first page to avoid confusion.

3. What is A0 Size?

A0 is one of the largest paper sizes in the A series and is often used for large technical drawings, such as architectural plans. In sewing, A0 is perfect for full-scale patterns, meaning you don’t have to tape pages together—it’s all on one sheet!

• Dimensions: A0 measures 841 mm x 1189 mm (33.1 inches x 46.8 inches).
• Sewing Pattern Use: A0 patterns are typically used by professional designers or seamstresses who need to print large, detailed patterns in one go. Instead of printing a pattern across multiple pages (like A4 or Letter size), A0 patterns come printed on a single large sheet, which saves you the time and hassle of piecing it together.

Pros of A0 for Sewing Patterns:

• Full-scale pattern prints on one large sheet—no assembly required.
• Ideal for larger garments or intricate designs.
• Perfect for projects that need precise scale and detail, such as coats, dresses, or complex patterns.

While A0 printing requires specialized equipment that most home printers can’t handle, don’t worry—there are plenty of online services that can print and ship A0 patterns right to your door! All you need to do is upload your file, pay, and wait for it to arrive. The cost per page is usually quite reasonable, especially when you factor in the time saved by not having to print and tape everything together yourself.

A tip: If you find a print shop that charges more than expected per page €€, shop around! Higher prices don’t always mean better quality or service—I've had great experiences with affordable print shops €.

Choosing the Right Size for Your Sewing Pattern Printing

When deciding between A4, Letter size, and A0, keep these factors in mind:

1. Size of the Project:

• For smaller garments or accessories, A4 or Letter size is probably all you need.
• For larger garments like coats or dresses, A0 is ideal, as it allows you to print the full pattern on one sheet, ensuring everything is to scale.

2. Printer Availability:

• A4 and Letter sizes are perfect for home printers, making them the easiest and most accessible options for most sewers.
• A0 requires a large-format printer, often available at professional print shops or fabric stores with printing services.

3. Pattern Assembly:

• A4 and Letter size patterns often require you to print multiple sheets and tape them together. It can be a bit time-consuming, but it's manageable for smaller patterns.
• A0 eliminates the assembly step entirely, providing you with a full-size pattern right from the start, saving you time and ensuring everything lines up correctly.

Final Thoughts

The paper size you choose for printing your patterns is crucial because it ensures your pattern is printed at the correct scale. Even small differences in size can affect how your finished garment turns out. The choice of size really depends on where you are based and the scale of your project!
