Choosing the correct size sewing pattern is crucial for a successful garment project. It ensures a proper fit and saves you from frustrating alterations. Don’t rely on ready-to-wear sizes; instead, measure your body accurately and compare these measurements to the pattern’s size chart.
Understanding Sewing Pattern Sizing: It’s Not Like Your T-Shirt!
Sewing patterns use a different sizing system than the clothes you buy off the rack. Ready-to-wear sizing can vary wildly between brands. Sewing patterns, however, rely on precise body measurements to guide you to the right size. This means your pattern size might be different from your usual clothing size.
Why Your Ready-to-Wear Size Doesn’t Translate
The fashion industry uses vanity sizing. This means sizes are often made larger than actual measurements to make consumers feel better about their purchase. Sewing patterns, on the other hand, are designed for accuracy. They assume you will be making adjustments, but starting with the correct size is the best foundation.
Key Body Measurements You Need to Take
To choose the correct sewing pattern size, you’ll need a few key measurements. A flexible tape measure is your best friend here.
- Bust: Measure around the fullest part of your bust, keeping the tape parallel to the floor.
- Waist: Measure around your natural waistline, which is usually the narrowest part of your torso.
- Hips: Measure around the fullest part of your hips, typically about 7-9 inches below your natural waist.
- Back Waist Length: Measure from the prominent bone at the base of your neck down to your natural waistline.
Pro Tip: It’s often easier to have a friend help you take these measurements for greater accuracy.
Navigating the Sewing Pattern Envelope: Your Sizing Roadmap
The sewing pattern envelope is packed with information. Beyond the illustration of the finished garment, you’ll find crucial details for selecting the right size.
Decoding the Size Chart
Every pattern will have a size chart. This chart lists the body measurements that correspond to each pattern size. Locate your measurements on the chart and find the size that best matches. Don’t be alarmed if your bust measurement falls into one size, your waist into another, and your hips into a third.
Understanding Finished Garment Measurements
Patterns also provide finished garment measurements. This tells you the actual dimensions of the completed garment. It’s important to understand that patterns include ease, which is extra fabric built into the pattern for comfort and movement. The amount of ease varies depending on the garment style. A close-fitting blouse will have less ease than a loose-fitting dress.
What About Height and Other Measurements?
Some patterns might also include measurements for height, inseam, or sleeve length. These are helpful for adjusting the pattern’s length to your personal proportions, especially if you are significantly taller or shorter than the pattern’s standard.
Common Pitfalls to Avoid When Choosing Pattern Size
Even with careful measurement, there are a few common mistakes that can lead to a poorly fitting garment.
Don’t Ignore Your Measurements for Ready-to-Wear Size
This is the most frequent error. Always trust your body measurements over your usual clothing size. A size 12 in a store might be a size 16 or 18 in a pattern.
Overlooking the Fabric Recommendation
The fabric choice significantly impacts how a garment fits and drapes. Patterns often recommend specific fabric types (e.g., lightweight cotton, stable knits). Using a fabric that is too stretchy or too stiff can alter the intended fit, even if you chose the correct size. Always check the fabric recommendations on the pattern envelope.
Forgetting About Adjustments
Even if you find a size that perfectly matches your measurements, you might still need to make minor adjustments. This is normal! Learning basic pattern alterations can elevate your sewing skills and ensure a custom fit.
Practical Examples: Putting It All Together
Let’s say you measure yourself and find:
- Bust: 38 inches
- Waist: 30 inches
- Hips: 40 inches
You look at a pattern’s size chart and see:
| Size | Bust | Waist | Hips |
|---|---|---|---|
| 10 | 36" | 28" | 38" |
| 12 | 38" | 30" | 40" |
| 14 | 40" | 32" | 42" |
In this scenario, Size 12 is the perfect match for all your measurements.
Now, consider if your measurements were:
- Bust: 38 inches
- Waist: 32 inches
- Hips: 40 inches
Looking at the same chart, you would select Size 12 for your bust and hips, but your waist measurement aligns with Size 14. This is a common situation. In such cases, you would typically choose the larger size (Size 14) and then grade between sizes during the cutting and sewing process, or simply take in the waist area as needed.
People Also Ask
### How do I know if a pattern is too big or too small?
A pattern is too big if you have excessive fabric pooling, drooping, or stretching in areas like the shoulders, bust, or waist. It’s too small if the fabric is pulling tightly across your body, restricting movement, or if seams feel strained. Always refer to your body measurements against the pattern’s size chart as your primary guide.
### Should I size up or down in sewing patterns?
You generally do not "size up" or "size down" in sewing patterns in the same way you might with ready-to-wear clothing. Instead, you choose the pattern size that corresponds to your body measurements as listed on the pattern envelope’s size chart. If your measurements fall between sizes, it’s often recommended to choose the larger size and then make adjustments.
### What is the difference between pattern size and ready-to-wear size?
The primary difference is accuracy. Ready-to-wear sizes (like S, M, L, or numerical sizes 0-16) are often inconsistent and subject to vanity sizing. Sewing pattern sizes, however, are based on standardized body measurements and are intended to be a precise starting point for creating a garment that fits you well.
### How do I measure myself for sewing patterns?
Use a flexible tape measure and stand naturally. For the bust, measure around the fullest part. For the waist, measure around your natural waistline. For the hips, measure around the fullest part of your hips. Always ensure the tape measure is snug but not tight, and keep it parallel to the floor for accurate readings.
