Our Fit Development & Size Grading Process
We follow a structured fit development and size grading workflow to ensure every garment is accurate, consistent, and production-ready:
Prototype fitting: We assess initial samples for size, balance, proportions, movement, and wearer comfort.
Size grading: We scale the approved base pattern into a full size range while maintaining consistent shape and fit.
Adjustment and refinement: We apply fit corrections and pattern updates to improve sizing accuracy before bulk production.
Tech pack integration: We document approved grading details and fit specifications within our Apparel Tech Pack Development process for smooth manufacturing execution

Frequently Asked Questions About Fit and Size Grading.
At Eco Jersey, we know that accurate fit and consistent size grading are essential for successful apparel production. These FAQs explain how our fit development and grading services help brands refine sizing, reduce production risk, and prepare styles for efficient bulk manufacturing.
Whether you are developing a new collection or improving an existing size range, we provide flexible apparel manufacturing solutions to support both low-volume development and large-scale production.
Fit development is the process of refining a garment’s pattern and sample so it matches your target measurements, silhouette, and comfort level before production. It includes trial fittings, balance and proportion checks, and adjustments to ensure the style fits correctly on the intended customer profile.
What is size grading and why is it important?
Yes, we can work from your existing patterns, tech packs, or sample garments if you already have them. Our team reviews your current fit, then refines and grades the patterns so they are production-ready and aligned with your preferred sizing strategy.
Once fit and grading are approved, we integrate all measurements and grading rules into our Apparel Tech Pack Development so production teams have clear instructions. These tech packs then feed into Cut and Sew Manufacturing and our Apparel Quality Control System to keep sizing consistent in bulk orders.
In most cases, yes. If you share your existing brand size chart or measurement tables, we align our fit development and grading to match your current sizing so new styles are consistent with what your customers already wear.
