extra extra small
That is extra extra small (the manufactured size).
extra extra small: the smallest standard size category
Extra extra small, abbreviated XXS, is a size designation in manufacturing that sits below the standard XS (extra small) category. It represents garments, components, or products manufactured to fit the smallest end of the adult range, though XXS is increasingly common in children's sizing as well. The exact measurements vary by industry and region, but in apparel, XXS typically corresponds to chest measurements around 31 to 33 inches for women's cuts.
In garment manufacturing, XXS emerged from the expansion of size grading systems to accommodate both very petite adults and the growing children's market. Pattern graders and sample makers must work with tighter tolerances at this size; armholes, necklines, and sleeve caps become particularly critical since proportional scaling down from a base size (usually a medium) can result in garments that hang incorrectly or restrict movement. Many factories now grade XXS alongside their standard range, though some specialization exists: certain contractors focus exclusively on small-scale production.
Application across trades
Beyond apparel, XXS applies to footwear (children's shoe sizes often use this designation), accessories, and even industrial protective equipment. In PPE manufacturing, XXS gloves or aprons must meet the same safety standards as larger sizes while accommodating smaller hand spans or frame dimensions. Suppliers working in niche markets, such as petite-specific clothing or specialist athletic wear, treat XXS as a core rather than marginal size.
The challenge in XXS production lies in yield and efficiency. Marker planning (the laying out of pattern pieces on fabric) becomes less forgiving at small sizes; waste increases unless pieces are arranged carefully. Quality control tolerances remain identical to larger sizes, so seam allowances, hem widths, and closures cannot be arbitrarily reduced simply because the garment is smaller. This can make XXS unprofitable for low-volume runs, pushing production toward larger batch minimums or higher per-unit costs.
