Ask any procurement manager what goes wrong with a bulk uniform order and the answer is usually sizing. Get it right and the order lands smoothly; get it wrong and you are reordering odd sizes for weeks. This guide shows how to plan sizing for a bulk order, with an indicative size chart to start from.
Why sizing is the hardest part
A bulk order covers many people of different builds. Unlike a single purchase, you cannot try each garment on, so you rely on a size set and a quantity split. The goal is to order the right number of each size the first time, with a small buffer for error and new joiners.
Step 1: Measure (or collect sizes)
The most reliable approach is to collect each person's size against a standard chart. For tops, the key measurement is chest (around the fullest part); for trousers, waist and inseam. For a faster approximate method, ask staff for their usual shirt/trouser size. For schools, collect sizes class by class.
Step 2: Build your size set
A standard adult size set runs roughly XS to 5XL. Below is an indicative guide — confirm exact measurements against your manufacturer's chart before ordering, as fits vary by garment and fabric.
| Size | Indicative chest (inches) | Indicative waist (inches) |
|---|---|---|
| XS | 34–36 | 28–30 |
| S | 36–38 | 30–32 |
| M | 38–40 | 32–34 |
| L | 40–42 | 34–36 |
| XL | 42–44 | 36–38 |
| 2XL | 44–46 | 38–40 |
| 3XL | 46–48 | 40–42 |
| 4XL | 48–50 | 42–44 |
| 5XL | 50–52 | 44–46 |
Indicative only. Always confirm against the manufacturer's actual chart and an approved sample.
Step 3: Plan the size-wise split
Translate your collected sizes into a quantity per size. A good manufacturer supports a size-wise split within one order rather than forcing an even distribution — so you order what your team actually needs. Share this split with your quote request for accurate pricing.
Step 4: Add a buffer
Order a small buffer in the most common middle sizes (M, L, XL) and a few extras at the edges for new hires, growth (for schools) and replacements. A modest buffer in the initial bulk order is cheaper than tiny reorders later — related: why minimum order quantities exist.
Step 5: Approve a sample for fit
Before bulk production, approve a sample in your chosen fabric and size to confirm the fit matches the chart. Fit can vary with fabric and cut, so this step prevents a whole order coming out a size off.
For schools and growing teams
Children grow during the year, and teams hire mid-cycle. Keep a buffer of common sizes so you are not reordering single pieces every month, and plan annual orders that anticipate growth and intake.
