Size Recommendation for Uniform Suppliers

Size recommendation for uniform suppliers works best when each staff member gets a size from your own workwear chart, instead of guessing from a generic label. A short body scan on their phone matches their measurements to your chart, so a bulk order is built from data, not from "I think I'm a medium."

This guide is for suppliers who sell workwear, school wear or corporate uniforms online. For the general picture of how AI sizing works in fashion, see our guide to AI size recommendation for fashion stores.

Why is uniform sizing harder than normal retail?

Uniform orders have problems that a single shopper buying a shirt doesn't.

• Someone else often orders. An office manager or HR lead places the order for 40 people. They don't know each person's size.
• People guess. Staff asked by email often give the size they bought last time, from a different brand.
• Many people, many shapes. One order can cover a wide range of heights and builds, often across men's and women's cuts.
• Swaps are slow. Each wrong size means a return, a reorder and a staff member waiting for the right item.
• Fit affects safety and comfort. Workwear that is too tight limits movement, and sleeves or trousers that are too long can catch.

A size tool won't fix every problem. It does fix the guessing, which is where most wrong sizes start.

How does a size scan work for staff?

Each staff member opens your product page on their phone, uploads one full-length photo and enters their height. The scan takes about 30 seconds and returns measurements.

Those measurements are matched to the size chart you have entered for that garment type. The staff member sees one label from your chart, such as "M" or "Size 14". If they fall between two sizes, the tool sizes up to cover the largest relevant measurement, since a slightly loose uniform is easier to wear than a tight one.

If you haven't entered a chart for a garment type, the tool uses a generic UK, US, EU or AU chart instead. For uniforms, enter your own chart. Workwear often has its own cut, and generic charts won't match it.

How should you set up your uniform size charts?

Your charts drive every recommendation, so set them up carefully. Enter them in Dashboard → Size charts, or in the Shopify app if you sell on Shopify.

Use one chart per garment type

Make separate charts for tops, outerwear, dresses and bottoms. A polo shirt, a fleece and a pair of work trousers all fit differently.

Enter body measurements, not garment measurements

Use the body measurements of the person each size is meant for. Don't use the flat width of the garment.

Close the gaps between sizes

Make each size's range meet the next one. A gap leaves some staff with no clear answer.

Example: a workwear tops chart

This is an example chart only. Check your own brand's chart before you use any numbers.

Size	Chest (cm)
S	86–94
M	94–102
L	102–110
XL	110–118
XXL	118–126

For bottoms, add waist and hip ranges. The way denim brands handle waist and hip ranges is a useful model, covered in size recommendation for denim brands.

How do you run a bulk uniform order with size scans?

Here is a simple workflow that suits most suppliers and their business clients.

1. Set up the charts for every garment in the uniform range.
2. Send staff a product link. The buyer shares a link to each uniform item with their team.
3. Each person scans once and notes the size the tool suggests for each garment.
4. Collect sizes in one list. The buyer gathers names and sizes in a spreadsheet or order form.
5. Order with a small buffer. Many buyers add a few spare items in the most common sizes for new starters.
6. Check outliers. If someone's suggested size looks unusual, ask them to scan again with a clearer photo.

This works the same way when a parent orders school wear for a child. The parent runs the scan with the child's photo and height.

Tips for a smoother rollout

• Give clear photo instructions. Ask staff to stand in fitted clothing, against a plain wall, with their whole body in frame.
• Set a deadline. A short window, such as one week, stops the order stalling while the buyer chases late replies.
• Name one contact. Staff with questions about fit should know who to ask, whether that is the buyer or your support team.
• Keep the list for next time. New hires and reorders are faster when the buyer already has sizes on file.

Which uniform types benefit most?

Sizing matters more for some uniforms than others. Use this checklist to decide where to start.

• Fitted garments. Blazers, tailored trousers and dresses have less room for error than a loose T-shirt.
• Mixed-gender teams. Different cuts mean more chances to order the wrong one.
• Remote or shift teams. Staff who can't attend a fitting session gain the most from a phone scan.
• High-turnover roles. New starters can scan on day one instead of waiting for a fitting.
• Modest or long-length uniforms. Lengths and loose fits need their own charts. Our guide to size recommendation for modest fashion stores covers how to handle relaxed fits.

Some suppliers also sell made-to-order or occasion items. Boutiques that size dresses for single events face similar issues, as described in size recommendation for bridal boutiques.

What does it cost to run size scans on uniforms?

Each scan uses one measurement from your monthly plan. The Free plan is $0 and includes 3 try-ons, 3 measurements and 5 invoices a month, enough to test your charts.

Paid plans are Micro at $14 a month, Starter at $49, Growth at $129 and Scale at $299. Every paid plan has a 3-day free trial with no card required. For a large team, pick a plan based on how many staff will scan each month. See the current plan limits before a big rollout.

You can add the tool through the Shopify app, a script tag on WooCommerce, Wix, Squarespace, BigCommerce or a custom site, or the REST API if you run your own ordering portal.

FAQs

Can staff scan without creating an account?

Yes. Staff open your product page, upload a photo and enter their height. There is no app to download.

Can I use different charts for men's and women's uniforms?

Make sure each product points to the right garment type chart. If your men's and women's cuts differ a lot, sell them as separate products with their own setup.

What if a staff member is between two sizes?

The tool sizes up to cover the largest relevant measurement. For uniforms, that usually means a little room for movement.

Does it work for children's school uniforms?

The parent can run the scan with the child's photo and height. Enter a chart that matches your school wear sizes so the labels match what you sell.

Can a buyer see everyone's sizes in one place?

The scan shows a size to each person on the product page. Ask staff to send their result to the buyer, who collects them in one order list.
