How to calculate knit fabric stretch percentage for perfectly fitted sewing projects
When working with knit fabrics, understanding fabric stretch percentage is the secret to achieving a garment that fits just right. For sewing patterns like Moriko, designed for fitted styles, knowing how much your fabric stretches can make the difference between a perfectly snug fit and a piece that’s too loose or too tight. In this post, we’ll walk you through how to measure knit fabric stretch and explain why it’s so critical for your sewing projects!
What is fabric stretch percentage?
Fabric stretch percentage refers to how much a fabric can stretch compared to its original length—usually measured along the cross-grain (the direction with the most stretch).
For example:
If a 10 cm section of fabric stretches to 12 cm, it has 20% stretch.
This measurement is especially important when sewing knit garments, as it directly impacts the fit and comfort of your final piece.
The Moriko sewing pattern is drafted for fabrics with at least 20% stretch, making it versatile yet precise. If you’re working with fabrics that stretch beyond 30%, consider sizing down to maintain that beautifully snug fit.

Why Does Fabric Stretch Percentage Matter?
Choosing the wrong fabric stretch can lead to fit disasters—too loose, too tight, or completely off balance. When you calculate your fabric’s stretch percentage and compare it to your pattern’s requirements, you remove the guesswork and ensure a flawless fit every time.
In our guide, we also tackle these essential questions:
- What is negative ease, and how does it affect fit?
- What if fabric stretch isn’t mentioned in the pattern?
- What if I want to use a fabric that’s different from what’s recommended?
