A hi-vis jacket that rides up when someone bends, trousers that catch at the ankle, or a fleece too tight to layer over a polo are not minor uniform issues. They affect comfort, movement and whether staff will wear the garment correctly. Knowing how to choose safetywear sizes starts with treating fit as an operational requirement, not an afterthought when placing a branded workwear order.

For teams, the most reliable approach is to collect measurements, match them to the individual garment's size chart and account for the job being done. A size labelled medium is not a standard measurement across every brand or garment type. Check the product information before assuming a member of staff takes the same size in a softshell jacket, hi-vis waistcoat and waterproof over-trouser.

How to choose safetywear sizes before ordering

Start by deciding what each garment will be worn with and when. A lightweight hi-vis polo may be worn directly over a T-shirt, while a waterproof jacket is often worn over a sweatshirt or fleece. Ordering both in the same nominal size can leave the outer layer restrictive.

Ask staff to provide current body measurements rather than their usual retail clothing size. For a jacket, sweatshirt or polo, chest measurement is normally the key figure. For trousers, measure the natural waist and inside leg. Where available, consider hip, height and sleeve length too, particularly for bib-and-brace styles, coveralls and longer coats.

Take measurements over close-fitting clothing, with the tape held level and snug but not pulled tight. Record the actual measurement in centimetres or inches and keep the format consistent across the team. It is usually better to ask staff to measure themselves privately or use a simple sizing form than to make assumptions based on appearance.

Read garment charts correctly

The most common ordering mistake is confusing body measurements with garment measurements. A size chart may show the chest size of the wearer, or it may show the measured width of the finished garment. The difference matters.

If the chart states a garment chest measurement, compare it with a well-fitting item that the wearer already owns. Lay that item flat, measure across the chest under the arms, then double the figure. If the chart gives a body chest range, choose the size designed for that body measurement and allow for the garment's intended ease.

Do not use a general chart for every item in a mixed order. Size grading varies between manufacturers, and unisex garments can fit differently from dedicated women's ranges. This is especially relevant when ordering branded workwear across polos, hoodies, fleeces, jackets and hi-vis layers from more than one range.

Allow room for work, weather and PPE

Safetywear is worn while lifting, climbing, driving, reaching, kneeling and working outdoors. The right size must support those movements without excess fabric becoming a snag risk or getting in the way of machinery.

For outerwear, allow enough room for the layers staff genuinely use. A warehouse operative wearing a polo under a hi-vis vest needs less extra space than an engineer wearing a polo, sweatshirt and fleece below a waterproof coat. In colder UK conditions, this difference is often the reason an outer jacket needs to be one size larger than the person's usual top.

That does not mean sizing up every garment. Hi-vis waistcoats that are too large can hang loose, shift around the body and sit poorly around printed or embroidered branding. Oversized trousers can catch under boots or drag on wet ground. Aim for controlled ease: enough room to move and layer, but no unnecessary bulk.

Check how existing PPE affects the fit as well. Harnesses, tool belts, kneepads, gloves and body armour can all change the way a garment sits. A worker who wears a harness over a jacket may need a different style or size from a colleague doing the same role indoors. If a garment has a high collar, adjustable cuffs or a longer back, make sure these features work with the equipment already in use.

Fit checks for common safetywear items

Hi-vis waistcoats should sit comfortably over the planned base layer, fasten without strain and cover the torso without restricting access to pockets or tools. The reflective bands should lie flat rather than twist around the body.

Hi-vis polos, T-shirts and sweatshirts need comfortable room across the shoulders and chest. Check that raising both arms does not pull the hem excessively high or tighten the neck. This matters where the garment carries a chest print or embroidered logo, as stretched fabric can make branding sit unevenly.

Jackets and softshells need a full movement check. Ask the wearer to reach forward, reach overhead, sit down and bend at the waist. The sleeves should not pull far above the wrist, the back should remain covered and the zip should close without pulling across the chest.

Trousers, joggers and coveralls should allow kneeling and stepping up without tightness across the seat, thighs or crotch. The hem should work with the footwear worn on site. An inside leg that looks acceptable in trainers may be too short over safety boots or too long when climbing ladders.

Use samples for larger or mixed teams

For a first order, a sample size run can prevent costly exchanges and delays. This is particularly useful where staff are split across different roles, seasons or sites. Try-on samples give people a chance to test the fit over normal work layers instead of choosing from a label alone.

A sample is also useful when selecting between unisex and women's fits. Unisex garments can simplify ordering and stock management, but they do not suit every wearer. Offering appropriate fit options can improve comfort, staff acceptance and the likelihood that uniforms are worn as intended.

Keep a simple size record after the fitting. Note the garment brand, product style, colour, size and any sizing comment such as “size up for fleece underneath”. This makes repeat ordering faster and helps when new starters need matching items.

Plan sizes around the decoration process

Branding does not usually change the underlying size, but it can affect how a garment feels and performs. Large front or rear prints can make lightweight fabric feel less flexible, while embroidery adds density in a small area. A chest logo on a close-fitting polo is normally straightforward; a large print across a stretch garment needs more consideration.

Check the available print and embroidery areas for each size, especially on small garments. A design that works across adult large sizes may need a reduced logo width on extra-small sizes to avoid printing too close to seams, zips or reflective bands. On hi-vis products, decoration must not interfere with required visibility features or cover reflective tape.

Where staff names, job roles or individual numbering are included, confirm the final size list before production starts. Changes after garments have been decorated are rarely straightforward, and personalised items may not be suitable for return or exchange.

Avoid the costly shortcuts

Ordering one standard size per department, using old uniform records without checking them, or relying on everyday clothing sizes can all create avoidable waste. Staff may have changed size, the previous garment range may have fitted differently, and a role may now require additional layers or equipment.

Avoid ordering every size in equal quantities for spare stock too. Review the actual distribution from your team, then hold a practical spread of the sizes you use most. If your workforce changes regularly, consider keeping a small number of undecorated garments for urgent fitting and finishing them once the new starter's size is confirmed.

For safetywear that is also PPE, size is only one part of selection. The garment must be suitable for the workplace risk assessment, the task and any applicable performance requirements. A correctly sized hi-vis item is not automatically suitable for every environment, weather condition or hazard.

A clear measurement process takes a little longer before an order, but it protects the budget, reduces rework and gives staff garments they can use properly from their first shift. Get the size list right before adding logos, names or print placements, and the finished safetywear will look consistent, feel practical and stay useful on the job.
