How to Calculate Uniform Quantities for Staff

A uniform order that is 10 shirts short can hold up a site launch. An order with 40 unused hoodies ties up budget and leaves stock taking up space. Knowing how to calculate uniform quantities means finding the sensible middle ground: enough garments for every person to look consistent, plus a planned allowance for real-world changes.

For businesses, schools, clubs and event organisers, the right quantity depends on more than headcount. Role, shift pattern, garment type, laundry access, season and expected staff turnover all affect the final number. Start with the people you need to kit out, then build the order around how the uniform will actually be worn.

Start with an accurate wearer list

The most reliable place to begin is a current list of people who need uniform. Ask managers, team leaders or organisers to confirm names, roles, employment status and required sizes. Do not rely on an old payroll report or last year’s order if the team has changed.

Separate wearers by role before adding quantities. Office staff may need branded polos and jackets, while warehouse staff may require tees, hoodies and hi-vis layers. A sports club may need playing tops for registered members, plus a small number of extras for late registrations. When every role has its own line, it is much easier to see where an item is necessary and where it is not.

Your starting calculation is simple:

Number of people in each role × garments required per person = base quantity

If 18 delivery drivers need three polos each, the base order is 54 polos. If those same drivers each need one jacket, that is 18 jackets. Keep each product separate rather than treating the whole uniform as one total.

How to calculate uniform quantities by garment type

Not every item needs the same per-person allowance. The practical question is how often the garment is worn and how easily it can be washed, replaced or shared.

Daily workwear needs more than one piece

For garments worn most days, such as t-shirts, polos, work shirts and singlets, two or three per person is usually a sensible starting point. Three is often the better option for customer-facing staff, tradies and teams working a full week, as it gives time for washing without employees arriving in mismatched gear.

A café team working five or six days may need three branded tees or polos each. A construction crew might need three hi-vis shirts, particularly where dirty or wet work is common. If garments are supplied for a short campaign or one-day promotion, one item per participant may be enough.

Outerwear is usually a one-per-person order

Hoodies, sweatshirts, jackets and vests are normally ordered at one per person. They are higher-value items, worn over other garments and less likely to need daily washing. A second layer can make sense for outdoor teams, people working across multiple sites, or staff who need one item at work and one in a vehicle.

Think about the New Zealand season too. A winter delivery schedule may justify a jacket for every team member, while a summer event may only need tees, caps or singlets. Ordering outerwear only for the people who genuinely need it keeps the budget focused on the garments that will get used.

Specialist items should match the job, not the whole team

Hi-vis garments, aprons, hospitality shirts, rainwear and safety-specific clothing should be counted against the roles that need them. It is rarely cost-effective to order specialist garments for every person just because they are on the same payroll.

For example, a landscaping company may provide hi-vis tees to field crews, branded polos to office staff and waterproof jackets to supervisors who spend time on site. One business, three different quantity calculations.

Build a size breakdown from real information

Getting the total quantity right is only half the job. A poor size mix can be just as costly. Ask each wearer for their preferred size in the specific garment style wherever possible. A medium in one fit is not always a medium in another, especially across women’s, men’s, kids’ and unisex ranges.

Give staff a clear deadline to provide sizes. If time allows, arrange sample sizing before confirming the order. This is particularly worthwhile for fitted women’s garments, workwear, jackets and hoodies, where people often prefer a different fit depending on how they layer clothing underneath.

If you cannot collect every size, use your existing uniform records or a sensible distribution based on your workforce. Avoid ordering mainly medium and large simply because they are common sizes. Make sure smaller and extended sizes are included where needed. It is better to order a size range that reflects your actual team than to guess and hope exchanges will be straightforward later.

For groups that will keep growing, a small number of unbranded or commonly branded spare garments in popular sizes can help. The right spare mix depends on your team, but medium, large and XL are often useful for general stock. Do not forget smaller, larger or women’s sizes if those are regularly needed in your workforce.

Add a controlled spare allowance

A spare allowance is not wasted stock when it is planned properly. It covers new starters, damaged garments, sizing changes, lost items and last-minute event registrations. The key is to add enough to protect the operation without automatically adding extras to every line.

For a stable team of 10 to 20 people, one or two spare tops in the most common sizes may be enough. For a larger business with regular hiring, a 5 to 10 per cent allowance on everyday garments is often more practical. For a one-off event, add spares only when registrations are still moving or when volunteers and crew are not fully confirmed.

Consider the cost of reordering as well. A small top-up order can carry setup time for logo printing and may not suit the same pricing as a larger bulk run. If branded garments are central to your presentation, holding a few extras can be cheaper and faster than placing a rush order after the fact.

That said, do not apply a flat 10 per cent to everything. Adding spare branded jackets, specialised rainwear or uncommon sizes without a clear reason can inflate the order quickly. Put the allowance where replacement is most likely and where stock can be used later.

Account for branding, stock and lead times

Uniform quantities should be finalised before logo application begins. Branded garments cannot always be returned or swapped, so confirm the style, colour, logo position and spelling before approval. A black polo and a navy polo may suit the same role, but they need to be counted as separate products if both are required.

Also consider whether all garments need branding. Some businesses order branded polos for front-of-house staff and plain layers for back-of-house use. Others use a printed t-shirt for events but keep plain stock on hand for volunteers and casual workers. This approach can reduce cost while still keeping the customer-facing team consistent.

Check stock availability early, especially when you need multiple sizes, a particular colour or a large run. If an item is unavailable in one size, you may need to choose an alternative garment or adjust the mix before the order is printed. Leaving this until the final day creates avoidable delays.

Use a simple order worksheet

A basic worksheet keeps the process clear. Create one row per garment, colour and role, then record the wearer count, per-person allocation, base quantity, spare allowance and final quantity. Add a separate size breakdown underneath each product.

For example, a 25-person warehouse team receiving three branded tees each would have a base quantity of 75. Adding five spare tees for new starters and replacements gives a final quantity of 80. The size breakdown might then be confirmed as small 8, medium 22, large 27, XL 16 and 2XL 7. Check that those size totals add back to 80 before sending the order through.

This worksheet also makes approvals easier. Managers can quickly see what each team is receiving, finance can see why quantities have changed, and the person arranging branding has a clean record of the final garment counts.

Review after the first uniform issue

The best information for the next order comes from what happened with the current one. After a few weeks, ask whether staff had enough daily tops, whether jackets were used, and which spare sizes moved first. Note any garments that stayed unopened or sizes that were repeatedly requested.

For ongoing uniforms, keep a running stock record rather than starting from zero each time. Record what is issued to new starters, what is held as spare stock and what needs replacing. This turns future ordering into a quick top-up calculation instead of a rushed guess.

A well-planned uniform order gives your people what they need without paying for excess stock. Start with confirmed wearers, order according to the job, use actual sizes, and keep a modest allowance where it makes commercial sense.
