Frequently Asked Questions
How do I fix a PDF pattern that printed the wrong size?
Measure the "Test Square" on your printed page. Enter that measurement as the "Current Size". Then enter the size it *should* be (usually 5cm or 2 inches) as the "Target Size". The result is the custom scale percentage you should use in your print settings.
Can I use this for grading patterns?
Yes, for simple resizing (e.g., making a bag 10% bigger). However, for fitted clothing, simple scaling changes the proportions (necklines get too wide, etc.). For clothing, proper grading is recommended, but this tool is great for accessories and motifs.
Does it matter what units I use?
No. As long as you use the same unit for both numbers (e.g., both in cm or both in inches), the percentage calculation will be correct.
