Free Size Versus Graded Sizing For Leggings

What Free Size Actually Means

A free-size legging is cut as one pattern engineered around how far the fabric stretches. It is not an average of S M and L. On a high-stretch polyester and spandex knit, one pattern can sit acceptably across a fit range that would otherwise need three sizes, which is why so much of the printed legging market is sold this way.

Where Free Size Wins

It wins wherever SKU count is the constraint. A marketplace seller testing six prints can carry six SKUs instead of eighteen. A boutique can put a print on the floor without stranding one size. A wholesaler can pack cartons without forecasting a size curve that has never been reliable for their customer base.

Where Free Size Fails

It fails when a brand publishes a fit standard. If your customer is choosing between a 10 and a 12 on your own size guide, free size makes that guide meaningless and your returns go up rather than down. It also fails at the extremes of a size ladder, where stretch alone cannot substitute for a graded pattern.

How Grading To Your Own Chart Works

If you have a size chart, the pattern is regraded to it before the sample is made, rather than after a bulk run has already been cut. The sample is then measured against your chart, and that approved sample stays the reference for every repeat. What you should not accept is a factory grading a plus range by scaling a small pattern up, because the waistband is the first thing that fails when you do.

Deciding For Your Own Range

Ask two questions. Does your customer buy by size or by look? And does your brand publish measurements you are held to? If the answers are look and no, free size will cut your costs without hurting you. If the answers are size and yes, grade it properly and sample it before bulk.
