If you already know what pattern making is, you've probably wondered: is the pattern for a store-bought t-shirt the same as for a custom-made suit? No, it's not. They come from very different logics, and understanding that difference explains a lot about why clothes fit you the way they do.
In this article, we'll explain, without jargon, the difference between industrial pattern making and custom pattern making, what types of pattern making exist based on the method, and where the sewing patterns you use at home fit in.
Industrial Pattern Making: Designed for Many Body Types
Industrial pattern making (or serialized pattern making) is used to produce clothing in quantity. Its objective is not to dress a specific person, but to dress many in the best possible way.
To achieve this, it starts from a "standard" body type: standard measurements that represent a statistical average. From this base pattern, size gradingis done, meaning the rest of the sizes (size 36, 38, 40, etc.) are mathematically generated by proportionally increasing and decreasing.
Its characteristics:
- It is based on standard measurement charts rather than on a real body.
- It prioritizes efficiency: cost, time, and fabric utilization.
- It includes ease designed to fit a wide range of people.
- A single pattern can be used to produce thousands of garments.
Its limitation: that "average body" doesn't exist. That's why a store-bought garment might fit you perfectly in the chest but wide in the waist: it's made for an average, not for you.
Custom Pattern Making: Designed for a Specific Body
Custom pattern making (or personalized pattern making) does just the opposite: it starts from a person's actual measurements. Each piece is drafted from that specific body, with its proportions, height, and particularities.
This is what is done in tailoring, haute couture, and, increasingly, in home sewing when you adapt a pattern to yourself.
Its characteristics:
- It starts from individual measurements, not a standard chart.
- It seeks the perfect fit above efficiency.
- It allows for correcting particularities: shoulders, waist, curves, height, etc.
- Each pattern serves, in principle, for only one person.
Its "limitation": it requires more time, more knowledge, and, in production, it is much more expensive. That's why it's not used in mass-produced clothing.
| Industrial Pattern Making | Custom Pattern Making | |
|---|---|---|
| Starts from | Standard measurement chart | Actual measurements of a person |
| Objective | Dress many people | Perfect fit for one body |
| Sizes | Graded into several sizes | Only one "size": yours |
| Priority | Efficiency and cost | Fit and precision |
| Used in | Mass production | Tailoring, haute couture, home sewing |
| Fit | Good "on average" | Optimal |
And the sewing patterns I buy? Where do they fit in?
Good question, because they are right in the middle, and that's their beauty.
A home sewing pattern is industrial in its origin: it is created from measurement charts and graded into several sizes, so that it can serve many people. But, unlike store-bought clothes, you have the pattern in your hands... and that changes everything.
Because you can:
- Choosing the size based on your real measurements rather than the store's.
- Combine sizes (bust from one, hip from another).
- Lengthen or shorten the pattern for your height.
- Adjust as needed before cutting.
That is: you start from a well-made industrial pattern and take it towards personalization. That is the superpower of sewing your own clothes. We explain how to take the first step in our guide on how to choose your size in a pattern.
And note, not all standard charts are the same: at BERA Patterns, we work with two measurement charts, one European and one Latin American, precisely because average proportions vary between regions. This way, the starting point is already closer to your actual body.
Types of Pattern Making by Method
Beyond industrial or custom, pattern making is also classified by how the pattern is created. These are the three main methods:
1. Flat Pattern Making
This is the most widespread. It is drafted on paper (or on screen) from measurements and geometric formulas. It starts with a base pattern —the basic body block, without embellishments—and from there, the pieces are transformed to create different designs.
It's the method taught in most courses and the one behind almost all the patterns you buy.
2. Moulage (or Draping)
Here, there's no calculation: it's modeling. The fabric is placed directly on a dress form, molded, draped, and pinned until the desired shape is achieved. Then, that fabric is taken apart and transferred to paper to become a pattern.
It's very intuitive and visual, ideal for designs with drapes, gathers, and complex volumes. It's widely used in haute couture.
3. Digital Pattern Making
The same work as flat pattern making, but with specific software (CAD type). It allows for extremely precise drafting, automatic size grading, and modifications without starting over.
It is the industry standard and also what is behind the digital PDF patterns you print at home.
So, which one is "better"?
None is better: they serve different needs.
- Industrial pattern making makes affordable clothing available to everyone.
- Custom pattern making achieves a fit that mass production cannot.
- Flat pattern making is precise and reproducible; moulage is creative and organic; digital is fast and scalable.
In fact, in practice, they are constantly combined: many designers start with moulage on a mannequin and then move to flat or digital patterns to refine and grade.
Frequently Asked Questions
What is the main difference between industrial and custom pattern making? Industrial pattern making starts from standard measurement charts to dress many people; custom pattern making starts from the actual measurements of a specific body to achieve an optimal fit.
What is size grading? It is the process of generating the rest of the sizes from a base pattern, proportionally increasing and decreasing its measurements. It is characteristic of industrial pattern making.
Are sewing patterns industrial or custom? Their origin is industrial (they start from charts and are graded into sizes), but by having them, you can adjust them, combine sizes, and personalize them as much as you want.
Whether you prefer to sew with pre-graded patterns or someday decide to try custom pattern making, understanding this difference will help you get the most out of every garment you make. At BERA Patterns, we start with good industrial pattern making, with European and Latin American charts, so you can personalize it until it's truly yours.
