Size chart
Body measurements for cleanwear coveralls, undergarments and lab coats, bootie sizes by shoe size, and SMR glove sizes. Measure two or three operators and order a sample before a bulk order.

This chart is a guide. Fit varies by garment style, so confirm sizes with a sample before your bulk order.

Sizing questions
Should cleanroom coveralls fit loosely?
Slightly. Operators need room to bend and reach without strain on seams, but excess fabric pumps air and particles out at the cuffs and neck. If an operator is between sizes, choose by height first.
Can you make sizes outside this chart?
Yes. We make custom sizes and adjust sleeve or leg length for your team. Send the measurements with your enquiry.
How do I size booties over safety shoes?
Size by the shoe the operator wears inside the bootie, not by bare foot size. If in doubt, go up one size.
