How to measure for workwear that fits first time.

Half of all workwear returns are self-inflicted: sizes guessed from a favourite tee, waists quoted from denial, one 'L' assumed to equal another. The cure is five measurements taken in five minutes with a fabric tape — and the two rules that turn them into garments that fit on arrival.

The rules

What turns numbers into fit

Rule one: measure the body, not the wardrobe. A favourite old garment has stretched, shrunk and been chosen for reasons memory flatters; the tape hasn't. (Workwear sizing is also honest by regulation — EN ISO 13688 requires declared sizes to map to body dimensions — so honest inputs meet honest labels.)

Rule two: read the maker's chart, every time. Sizes are not standardised across brands — one maker's L is another's XL, and workwear cuts vary deliberately (a coverall allows for layers and crouching; a softshell doesn't). Match your numbers to each chart rather than transferring letters between brands. Two refinements finish the job: size outer layers over what's actually worn beneath (the winter-shell rule from the layering guide), and for teams, collect measurements at intake rather than asking people to shout sizes across a yard — it's quicker than one exchange paperwork cycle, and it feeds the quantity maths a real size curve, including the range edges.

Questions

Sizing FAQ

How do you measure chest size for workwear?

Tape around the fullest part of the chest, under the arms and level across the back, snug but not compressed, with arms relaxed. Match that number to the specific maker's size chart — letters like L and XL aren't standardised between brands.

Should workwear be a size bigger?

Not as a rule — modern workwear is cut for work, including layering allowances where relevant. The exceptions are deliberate: outer shells sized over real underlayers, and coveralls tested in a crouch. Otherwise measure honestly and follow the chart; oversizing creates its own snag and drape problems.

How should companies collect staff sizes?

Measure at intake with a fabric tape — five measurements per person, five minutes — rather than collecting self-declared letters. It feeds orders a real size curve including tall legs and extended sizes, and it costs less than one round of exchange postage.
