For home sewists

You want fit right the first time. You can’t afford rounds of rework, wasted fabric, or the back and forth of fixing problems that shouldn’t have been there in the first place. You don’t have a team to fall back on – when something doesn’t fit, it’s your time and your money lost. This chart gives you a tested base to draft from, so you stop guessing and start building blocks that actually work.

For brand owners and fashion studios

Whether you’re starting from scratch and asking “where do I even begin?” or you’ve been selling for years but every style fits differently – the problem is the same. Without one agreed measurement standard, sampling drags on, costs pile up, and your customers lose confidence in your sizing. You know something is off, but you can’t pinpoint where it went wrong. This chart gives you the foundation to standardise your sizing, align everyone who touches your product – from your pattern maker to your CMT – and build the consistency your brand needs to grow.

For trainers and pattern makers

You need one reliable base. Without it, every learner drafts differently, every freelancer works from their own numbers, and the block loses balance. You spend time correcting avoidable mistakes instead of teaching or creating. This chart gives you a tested, consistent standard to teach from, draft from, and hand over with confidence – so that everyone starts from the same agreed point.
