Yes, we provide comprehensive pattern grading services for all international sizing standards, including US, EU, and UK markets. You do not need to hire an external technical designer to scale your patterns—our in-house technical team manages the entire process for you.

Pattern grading is the precise method of scaling a base size (usually a Medium) up and down to create a complete size run (e.g., from XS to XXL) without losing the garment’s original shape, balance, and proportions.

Why Professional Grading Matters for Activewear and Outerwear

Grading technical garments is highly complex. It is never a simple “equal expansion” of all measurements.

  • For Sportswear (e.g., Hoodies, Leggings): The grading must account for the stretch mechanics of the fabric to ensure consistent compression and mobility across all sizes.
  • For Technical Outerwear (e.g., Hardshells, Down Jackets): The grade rules must factor in the “layering system.” A size XL hardshell needs carefully adjusted armhole depth and shoulder width to comfortably accommodate a heavy fleece or mid-layer underneath, without appearing boxy.

How Our Grading Process Works

We simplify the technical process for your brand through three clear steps:

1. Locking in the Base Size (Fit Sample) Before grading begins, we focus entirely on your “Base Size” (typically a Size M or L). Our paper pattern master develops the initial pattern, and we create a Fit Sample. We will not proceed until you approve the fit, drape, and proportions of this single benchmark garment.

2. Establishing the Grade Rules Once the Base Size is approved, we establish the “Grade Rules” based on your target market (US, EU, or UK) and your target demographic. We define exact grading jumps (the specific measurement differences between sizes)—for example, determining whether the chest width increases by 1 inch or 1.5 inches per size.

3. Digital CAD Execution Using advanced CAD (Computer-Aided Design) software, our technical team precisely scales the paper pattern into a full digital size set. This ensures mathematical accuracy for every single panel, ready for bulk cutting.
