Patternmaking & grading

Crafting garment patterns and grading them to fit various sizes goes beyond a technical task – it’s about capturing the interplay between design and functionality.

A skilled manufacturer has to understand the material – ensuring the finished garments fit and move as envisioned. At Isira, we’ve spent years perfecting this craft, creating patterns that translate seamlessly into stunning pieces of clothing.

Committed to absolute quality

Quality is at the heart of everything we do. We collaborate closely with you, understanding that your garment patterns need to be precise, size-consistent, and ready for efficient production.

For intricate designs, we go a step further, crafting mock-ups on mannequins to ensure a flawless fit before your patterns are finalized. Our quality management team inspects every stage of the process, guaranteeing your patterns are production-ready and right the first time.

All formats – from sketches to tech packs

Your vision guides our process. Whether your design is documented in a tech pack or captured in a quick sketch, Isira adapts to your preferred format. We seamlessly translate your ideas into precise patterns, ensuring a smooth transition from concept to creation, regardless of the starting point.

Latest technology, best technique

Isira’s pattern making and grading process is powered by advanced software. These programming solutions are renowned for their precision and intuitive features, ensuring exceptional accuracy and efficiency for both pattern creation and size adjustment.

Patternmaking & Grading common questions

Do you work with paper patterns?

Yes. We digitise paper patterns using specialist equipment and convert them into digital format for grading and production. We support all standard file formats including .mdl, .dxf, .hpgl, and .plt. If you’re unsure about compatibility, send us the file and we’ll confirm before starting.

What file formats do you accept for digital patterns?

We work with .mdl, .dxf, .hpgl, and .plt formats. These cover the most widely used patternmaking software outputs. If your file is in a different format, contact us and we’ll advise on the best conversion approach.

Can you create patterns from sketches or samples?

Yes. We can develop patterns from detailed sketches, technical drawings, tech packs, or physical garment samples. Our pattern makers will analyse the construction and translate it into a precise digital pattern ready for sampling and production.

What sizing systems do you work with?

We adapt to any sizing system — European, American, UK, or custom brand-specific sizing. We work from your specifications and ensure consistency and accuracy across the full size range.

Can you grade patterns for unusual or extended size ranges?

Yes. We can grade patterns for any size range, including plus sizes, petite ranges, or custom brand sizing that falls outside standard industry scales. We discuss the grading requirements with you in detail before starting to ensure the proportions and fit translate correctly across all sizes.

Can you adjust or update existing patterns?

Yes. We can modify existing patterns to improve fit, incorporate design changes, adapt to a different fabric weight or structure, or update a style for a new season. All adjustments are made with the same precision as original pattern development.

How long does patternmaking take?

Timeline depends on the complexity of the design and the number of sizes required. A straightforward pattern for a single size typically takes 1–2 weeks. Complex constructions or full size range grading may take 2–4 weeks. We confirm the timeline after reviewing your specific project.
