How to Plan Employee T-Shirt Sizes for Bulk Corporate Uniform Orders

Ordering company T-shirts for 30 employees is relatively simple. Ordering them for 300, 1,000 or several thousand employees across different departments and locations is a different purchasing challenge. A poor size breakdown can leave a company with too many shirts in rarely used sizes while employees in common sizes wait for replacements.

Effective bulk T-shirt size planning starts with an approved size chart, real employee data and a clear replenishment strategy. The objective is not to guess a universal size ratio, but to build an order around the people who will actually wear the garments.

Custom company T-shirts can be produced in different colors and sizes for employee uniform programs.

Size Chart vs Size Breakdown: Know the Difference

These two terms are easy to confuse, but they represent different parts of the corporate uniform purchasing process.

Example garment size reference. Buyers should confirm the final approved size chart before collecting employee size selections.

International sizing references can also help purchasing and product-development teams use more consistent terminology.    ISO 8559-1  provides anthropometric definitions used for body measurement, while  ISO 8559-2  addresses body dimensions used for clothing size designation.

This matters because a supplier's size label alone does not fully define fit. A Medium from one garment program may not have the same measurements as a Medium from another. Always confirm the actual approved measurements before employees choose their sizes.

Step 1: Confirm Who Will Receive the T-Shirts

Start with employee headcount rather than garment quantity. Create a list of the people or employee groups that will actually receive the shirts.

• Department or job function

• Office, store or branch location

• Number of current employees

• Expected new employees before the next uniform order

• Number of shirts issued to each employee

For example, if 600 employees each require three company T-shirts, the base purchasing requirement is already 1,800 garments before replacement stock or future hires are considered. Keeping wearer count separate from garment quantity makes later planning much easier.

Step 2: Approve One Size Chart Before Collecting Employee Sizes

Do not ask employees to submit S, M, L or XL until the actual garment size chart has been confirmed. A person who normally wears a Medium from one brand may require a different size in another fit or measurement system.

Before launching the size survey, confirm the following:

Step 3: Collect Employee Size Data

Once the approved size chart is available, collect employee selections in a structured format. Avoid relying on informal messages, screenshots or handwritten lists that become difficult to consolidate when hundreds of employees are involved.

Step 4: Convert Employee Data into a Size Breakdown

After collecting individual selections, consolidate the results into a size-by-size purchasing table. This becomes the working quantity for your quotation and purchase order.

Step 5: Add Extra Stock Based on Real Business Needs

Extra stock is useful for corporate uniform programs, but it should not simply be added as the same percentage to every size. A better approach is to identify why additional garments may be needed.

• New hires: estimate recruitment before the next planned production run.

• Size exchanges: use previous employee uniform data if available.

• Replacement garments: consider wearing frequency and the company's replacement policy.

• Business expansion: include planned branches, stores or new teams where appropriate.

Extra stock should also reflect the actual employee size profile. Adding the same number of spare XS and L garments may not make sense if these sizes are used at very different rates.

Step 6: Separate Size Breakdowns for Different Locations

Multi-location companies should consider maintaining both a master size breakdown and separate branch-level breakdowns. This can simplify packing, distribution and future replenishment.

If finished garments need to be packed by branch, department or employee group, communicate this requirement before production is completed. Sorting several thousand shirts after delivery can create unnecessary work for the buyer.

Step 7: Prepare for Repeat Corporate Uniform Orders

Corporate T-shirts are often replenished instead of purchased only once. New employees may join, stores may expand and existing staff may require replacement garments.

Keep a record of the following approved specifications:
