Quick answer: To print a PDF sewing pattern at the correct size, open the file in Adobe Acrobat Reader, select Actual Size or 100% scale, turn off Fit to Page, print the test square first, and check the measurement before cutting your fabric.
Buying a downloadable sewing pattern is exciting until you reach the printing stage and suddenly wonder if your printer is about to ruin the whole project.
If you have ever asked yourself “Why is my PDF sewing pattern printing smaller than it should?” or worried about wasting fabric because the template printed incorrectly, you are definitely not alone.
The good news is that printing a PDF sewing pattern correctly is actually very simple once you know which settings to check.
In this guide, we’ll walk through exactly how to print the Willow Crossbody Bag pattern at actual size, what the test square means, and how to avoid the most common printer scaling mistakes that can affect your finished bag.
The Willow Crossbody Bag is designed as a compact everyday bag with a flap closure, adjustable strap, and optional inner pocket. The finished size relies on accurate printing for the pattern pieces to align properly during construction.
If you’re still deciding whether this project suits your skill level, this beginner crossbody bag sewing pattern guide is a helpful next read.
Why Printing a PDF Sewing Pattern at the Correct Scale Matters
When a downloadable pattern prints even slightly too small or too large, every pattern piece changes size along with it.
That means your:
- Bag panels may not line up correctly
- Gusset pieces can become too short
- Flap placement may shift
- Hardware positioning can look uneven
- Finished bag dimensions may be incorrect
What happens if a sewing pattern prints too small?
If your printer automatically reduces the pattern size by even 3% to 5%, your finished bag can end up noticeably smaller than intended.
For projects like the Willow Crossbody Bag, this matters because the construction includes:
- Curved gusset seams
- Precise flap alignment
- D-ring tab positioning
- Snap placement
Even minor scaling problems can affect how those sections fit together.
Why small scaling errors matter more in bag sewing
Unlike loose garments where tiny differences may go unnoticed, bag sewing depends heavily on structure and alignment.
The Willow Crossbody Bag includes:
| Feature | Why Accurate Printing Matters |
|---|---|
| Front and back panels | Need matching dimensions for clean assembly |
| Gusset pieces | Must align exactly around curves |
| Flap placement | Needs proper scaling for snap alignment |
| Strap hardware positioning | Depends on balanced proportions |
The sewing guide specifies a finished bag size of approximately 7 inches high, 6 inches wide, and 1.5 inches deep. Those dimensions only work correctly when the pattern pieces are printed at full scale.
Why home printers often change the scale automatically
Most home printers are actually trying to “help” by adjusting files automatically.
Common automatic settings include:
- Fit to Page
- Shrink Oversized Pages
- Scale to Fit
- Borderless Adjustment
Unfortunately, these settings are exactly what can cause a sewing pattern to print incorrectly.
That is why sewing patterns should always be printed using Actual Size or 100% scale.
What “Print at Actual Size” Really Means
One of the biggest points of confusion for beginners is the difference between Actual Size and Fit to Page.
They sound similar, but they produce very different results.
The difference between “Fit to Page” and “Actual Size”
| Printer Setting | What It Does | Recommended for Sewing Patterns? |
|---|---|---|
| Actual Size / 100% | Prints the pattern at true dimensions | Yes |
| Fit to Page | Automatically shrinks or enlarges pages | No |
| Scale to Fit | Adjusts sizing to printer margins | No |
| Custom Scale | Allows manual resizing | Only if instructed |
For the Willow pattern, you should always select:
- Actual Size
- or 100% Scale
Never choose Fit, Shrink, or Scale to Fit.
Why PDF viewers matter
Another surprisingly common issue is printing directly from a browser window.
Browsers sometimes apply their own hidden scaling adjustments, especially on mobile devices or tablets.
For best results, download the file first and open it in a dedicated PDF viewer such as Adobe Acrobat Reader.
This gives you full access to the correct print settings and reduces scaling problems.
Where to find the correct print settings
Inside Adobe Acrobat Reader, look for:
- Page Sizing & Handling
- Size
- Actual Size
Make sure the scale reads exactly 100%.
If your printer settings show anything like 95%, 97%, or “Fit”, the pattern will not print accurately.
How to Print the Willow Crossbody Bag Pattern Correctly at Home
If you are printing a PDF sewing pattern for the first time, do not worry. The process is much easier than it looks once you know which settings matter.
Follow these simple steps before cutting any fabric.
Step 1: Download the pattern to your device
Always download the pattern file first instead of opening it in a browser preview.
This helps avoid hidden browser scaling problems that can affect the size of your bag template.
Save the file somewhere easy to find, such as:
- Your Downloads folder
- A sewing patterns folder
- Your desktop
Step 2: Open the file in Adobe Acrobat Reader
For the most accurate results, open the file using Adobe Acrobat Reader or another dedicated PDF viewer.
Avoid printing directly from:
- Google Chrome
- Safari
- Mobile browsers
- Email preview windows
These programs sometimes add automatic printer scaling without making it obvious.
Step 3: Select the correct paper size
The Willow Crossbody Bag pattern is designed for A4 paper.
Before printing, check that your printer settings also show:
- A4
- Portrait orientation unless otherwise stated
- Single-sided printing
If the printer is accidentally set to US Letter paper, the pattern may shift or resize slightly.
Step 4: Turn OFF “Scale to Fit”
This is the most important step.
In your printer settings, make sure:
- Actual Size is selected
- Scale reads 100%
- Fit to Page is turned OFF
- Shrink Oversized Pages is turned OFF
If you only remember one thing from this guide, make it this.
Most pattern printing problems happen because scaling settings were left on accidentally.
Step 5: Print the test page first
Before printing the entire pattern, print only the page containing the test square.
This saves paper, ink, and frustration.
Once printed, measure the square carefully using:
- A quilting ruler
- A measuring tape
- A hard ruler with millimetres
If the square measures correctly, you can confidently print the rest of the pattern.
Step 6: Measure carefully before continuing
Even a small measurement difference matters.
If the test square is supposed to measure 1 inch or 5 cm, it should match exactly.
If it is slightly off:
- Recheck the scaling settings
- Confirm the paper size
- Close browser printing windows
- Try Adobe Acrobat Reader instead
Do not continue cutting fabric until the test square is accurate.
What Is a Test Square on a PDF Sewing Pattern?
A test square is a small measurement box included on sewing patterns to help you confirm the file printed correctly.
It is one of the most important parts of any printable sewing template.
Why sewing patterns include a test square
The test square acts like a quick accuracy check before you use the full pattern.
Instead of guessing whether your printer scaled the file incorrectly, you can measure the square and know immediately.
This prevents:
- Incorrect bag sizing
- Wasted fabric
- Misaligned seams
- Hardware placement problems
- Frustrating assembly issues
How to measure the test square correctly
Lay the printed page on a flat surface and measure directly across the printed lines.
Do not measure:
- The outside page margins
- The shadow from the printer edge
- The surrounding white space
Measure only the actual printed square.
For best accuracy:
- Use a rigid ruler instead of soft tape
- Measure twice
- Check both width and height
What if the test square is wrong?
If the square does not measure correctly, stop before printing the remaining pages.
Usually the issue comes from one of these common problems:
| Problem | Likely Cause | Fix |
|---|---|---|
| Pattern printed too small | Fit to Page enabled | Select Actual Size |
| Pattern printed too large | Custom scaling enabled | Reset to 100% |
| Edges missing | Wrong paper size selected | Switch to A4 |
| Measurements inconsistent | Printed from browser | Use Adobe Acrobat Reader |
| Pages shifted slightly | Borderless settings active | Disable borderless printing |
Why beginners often struggle with PDF pattern printing
Many new sewists assume the problem is with the pattern itself when it is usually just a printer setting.
Modern printers automatically try to resize documents so they “fit” neatly on the page.
That works well for office documents, but not for PDF sewing patterns where every millimetre matters.
Once you know how to disable scaling properly, printing patterns becomes much more straightforward.
Can You Use an A4 Sewing Pattern Outside the UK?
Yes, absolutely.
Many sewists outside the UK successfully use A4 sewing patterns every day. You simply need to make sure your printer settings match the paper format used by the pattern designer.
A4 vs US Letter paper explained
The main difference is the physical paper size.
| Paper Type | Dimensions | Most Common In |
|---|---|---|
| A4 | 210 × 297 mm | UK, Europe, Australia |
| US Letter | 8.5 × 11 inches | USA, Canada |
Because the sizes are slightly different, printers sometimes try to resize the pattern automatically.
That is why checking the print settings matters so much.
Will the Willow Crossbody Bag pattern still print correctly internationally?
Yes, as long as you:
- Select the correct paper size
- Print at Actual Size
- Confirm the test square measures correctly
The sewing guide itself uses approximate measurements and a standard ¼ inch seam allowance, which makes accurate template printing especially important during assembly.
Tips for US and Canadian sewists
If you live in the United States or Canada, you have a few options:
- Print directly onto A4 paper if available
- Use a printer that supports multiple paper formats
- Print at a local copy shop
- Check whether the pattern includes a US Letter version
Most importantly, always verify the test square before printing the full pattern.
Common PDF Sewing Pattern Printing Problems (And Fixes)
Even experienced sewists occasionally run into printing problems.
Here are the most common issues and the easiest ways to fix them.
Why did my sewing pattern print smaller than expected?
This is usually caused by automatic scaling.
Your printer may have:
- Shrunk the document to fit margins
- Applied hidden browser scaling
- Used the wrong paper format
Switching to Actual Size typically fixes the problem immediately.
Why are the edges of my pattern missing?
If parts of the page are clipped or missing, the printer may:
- Be set to the wrong paper size
- Have borderless printing enabled
- Be adjusting margins automatically
Double-check both your printer settings and the PDF print preview before printing.
Why printing directly from a browser can cause issues
Browser printing is one of the biggest causes of incorrect pattern scaling.
Some browsers automatically:
- Resize PDFs
- Add margins
- Compress pages slightly
- Ignore saved PDF settings
Downloading the pattern and opening it in a dedicated PDF viewer is far more reliable.
Best printer settings for sewing patterns
| Setting | Recommended Option |
|---|---|
| Scale | 100% / Actual Size |
| Paper Type | A4 |
| Page Handling | No Scaling |
| Borderless Printing | Off |
| Print Source | Adobe Acrobat Reader |
Tips Before You Cut Your Fabric
Once your pattern prints correctly, take a few extra minutes to double-check everything before cutting into your fabric.
This small step can save a lot of frustration later.
Double-check your seam allowance
The Willow Crossbody Bag guide uses a ¼ inch seam allowance unless otherwise stated.
Make sure:
- Your machine is set up accurately
- You are sewing consistently
- Your seam guide is aligned properly
Even with perfectly printed pattern pieces, inconsistent seam allowances can change the final bag size.
Tape pattern pages carefully
When assembling multi-page patterns:
- Trim page edges neatly if required
- Match alignment marks carefully
- Tape pages on a flat surface
- Check curves and corners line up smoothly
Rushing this stage can distort the final shape of the bag.
Verify key measurements before cutting expensive fabric
Before using your outer fabric or fusible fleece, it helps to compare a few printed pattern measurements against the finished dimensions listed in the guide.
The Willow Crossbody Bag is designed as a compact everyday crossbody with structured proportions and carefully balanced hardware placement.
Taking a few extra minutes to verify sizing can prevent wasted materials later.

Key Takeaway: Most PDF sewing pattern printing problems are caused by automatic scaling settings, not the pattern itself.
Frequently Asked Questions
Why did my PDF sewing pattern print smaller than expected?
A PDF sewing pattern usually prints smaller than expected because the printer has automatically resized the file. This can happen if settings such as Fit to Page, Scale to Fit, or Shrink Oversized Pages are selected. For sewing patterns, choose Actual Size or 100% scale before printing.
What does Actual Size mean when printing a sewing pattern?
Actual Size means the pattern will print at the size it was designed, without being enlarged or reduced by your printer. This is the setting you need when printing pattern pieces that must match real measurements.
Do I need to print the test square first?
Yes. Always print the test square first and measure it before printing the full pattern. If the test square is wrong, the pattern pieces will also be wrong, which can affect the finished size of your project.
Can I print a PDF sewing pattern on A4 paper?
Yes, if the pattern is designed to work with A4 paper. Many PDF sewing patterns are supplied for A4, US Letter, or both. Check the pattern instructions before printing and make sure your printer settings match the paper size you are using.
Should I print a PDF sewing pattern from my browser?
It is better not to print a PDF sewing pattern directly from a browser. Browsers can sometimes resize the file without making it obvious. For more reliable results, download the PDF and open it in Adobe Acrobat Reader before printing.
What happens if I forget to print at 100% scale?
If you forget to print at 100% scale, the pattern pieces may come out too small or too large. Even a small change can affect the fit, shape, seams, pockets, straps, or finished size of a bag.
Can I reprint one page of a PDF sewing pattern?
Yes. If only one page has printed incorrectly, you can usually reprint that page on its own. Use the page number shown in your PDF viewer, check that the scale is still set to Actual Size or 100%, and measure the test square again if needed.
What is the safest way to print a PDF bag sewing pattern?
The safest way is to download the file, open it in Adobe Acrobat Reader, choose Actual Size or 100% scale, print the test square first, measure it carefully, and only then print the remaining pattern pages.
Final Thoughts
Printing a PDF bag sewing pattern correctly feels much easier once you know which settings matter. For the Willow Crossbody Bag, accurate printing helps the panels, gusset, flap and hardware placement line up properly, so it is worth checking the test square before cutting your fabric.
