Sizing decisions for company apparel carry more weight than most buyers realize. When someone opens their welcome kit and the shirt doesn't fit, the kit stops being a gesture of inclusion and becomes evidence of the opposite. That's a lot for a cotton tee to communicate, but here we are.
Why Extended Sizes Get Left Behind in the First Place
The honest answer is that nobody made a deliberate decision. Most people ops leads ordering apparel for the first time do what the vendor's order form encourages: they pick S through XL, maybe bump the ceiling to 2XL if they're feeling generous, and move on. The form makes it easy. The default size run feels complete.
The real driver is usually fear of waste. Buyers assume that larger sizes are riskier to stock because they'll be left over, without stopping to ask whether the size run was just too narrow to begin with. It's a self-fulfilling logic. Order too few extended sizes, have one go unclaimed because the person who needed it got a different size instead, decide extended sizes don't move.
There's also a cost assumption baked in that's only partially true. Extended sizes do carry a small upcharge at many vendors, typically $1 to $3 per unit above 2XL. That's real. But the calculus changes when you're ordering in a single production run, which we'll get to.
The suppliers who have done this longest will tell you that buyers who under-size their range are the ones who place the most frantic reorder calls two weeks later.
How Many Sizes Should You Actually Offer?
The answer isn't a formula pulled from some standard size chart. It starts with a real question: what does your workforce actually look like? A 30-person tech team that skews early-career in a major metro is going to have a different size distribution than a 200-person logistics company or a field sales team. Treating those as identical ordering situations is what produces a closet full of mediums nobody wants.
Collect size data before you touch an order form. This sounds obvious and yet most organizations skip it, ordering by instinct and then scrambling. A simple survey or onboarding form field asking for preferred apparel size takes five minutes to build and eliminates the guesswork that causes both waste and gaps.
As a starting framework, the U.S. adult population's apparel size distribution skews larger than the S-through-XL range most buyers default to. ASTM International's D5585 standard, which covers adult female body measurements for apparel sizing, documents how wide actual body diversity runs across a population. The data is not subtle. A range that tops out at XL leaves a meaningful portion of your team without a fit before you've even started.
For a mixed workforce of any size, XS through 3XL is a more honest baseline than XS through XL. Whether you need 4XL or 5XL depends on your actual survey data. The New Hire T-Shirt Size Calculator can help you translate headcount and a rough demographic picture into a per-size order breakdown, which is faster than building a spreadsheet from scratch.
The Math That Changes When You Build Inclusively from Day One
Here's the part that surprises most buyers. Ordering 2XL through 4XL as part of your initial production run is cheaper per unit than coming back for them later.
Screen printing and embroidery have setup costs baked into every run. Screens don't care how many shirts you're running through them, but the setup fee gets spread across every unit you order. A reorder of eight 3XL shirts carries nearly the same setup cost as a much larger order, which makes the cost-per-shirt on those eight units genuinely painful. A vendor who charges a $45 screen setup fee on a 200-piece order is effectively adding $0.23 per shirt. The same fee on a 10-piece reorder adds $4.50 per shirt before you've even looked at the unit price.
Order everything in one run. This is the structural argument for inclusive sizing that has nothing to do with principles and everything to do with procurement math. When you consolidate extended sizes into the core order, you spread setup costs, qualify for higher quantity pricing tiers, and avoid the operational mess of a second fulfillment wave.
The upcharge for extended sizes varies by vendor and garment. A Bella+Canvas 3001 runs roughly $1 to $2 more per unit above 2XL. A Next Level 6210 is similar. Port & Company's PC54 line is slightly cheaper at baseline but carries a comparable extended-size differential. These are real costs, and they're manageable ones when they're part of the plan from the start rather than a surprise on a reorder invoice.

5 picksWhat Happens When Someone's Size Isn't in Stock
This is the part of the conversation that tends to get softened, and it shouldn't be.
A team member who can't wear the shirt you handed out doesn't just have an inconvenient wardrobe situation. They have a repeating data point. Every time the team wears company apparel, they get a small confirmation that the people who planned the order weren't quite thinking of them. That's not a dramatic reading. It's just what the math communicates when someone is consistently excluded from a category called "everyone gets one."
The workaround options are all worse than just ordering correctly. Offering a gift card toward their own purchase puts the burden on the person who was already underserved. Ordering a custom one-off later costs more per unit and usually takes longer than the original run. Asking someone to wear an oversized shirt they didn't want to own signals that fitting them was an afterthought, not a plan.
None of this requires a policy memo or a DEI initiative. It requires a broader size range on the order form.
Not sure what fits your headcount and budget?
Vendors Who Won't Tell You Upfront About Size Limits
Not every supplier is equally useful here, and that's worth knowing before you commit to one.
A reputable vendor will tell you upfront which SKUs are available in which sizes, what the upcharge is above 2XL (if any), and what the minimum order quantity is per size (some require at least 6 units per size to run, which matters for smaller teams). They'll also tell you if a particular colorway isn't available in extended sizes for the garment you're looking at, which is genuinely useful information to have before you've approved artwork.
Watch out for vague pricing. "Extended sizes may carry an additional charge" is not useful information for planning. You need the actual number, by size break, before you build a budget. Vendors who can't give you that upfront are either using a pricing system that penalizes you for asking questions later, or they're not set up to handle inclusive sizing runs as a normal part of their workflow. Either way, that's your answer.
Some vendors also have garment lines that simply stop at 2XL or 3XL with no equivalent in extended sizes. That's a legitimate product constraint. The problem comes when a vendor presents a four-size range as comprehensive without disclosing the ceiling. Ask the question directly: what's the largest size available in this specific style and color, and what does it cost?

How to Talk to Your Team About What Fits
The survey question most people write is something like "What is your shirt size?" and then they offer XS, S, M, L, XL, 2XL. That's a leading question. It tells the respondent what sizes you're planning to order, and anyone who needs a 3XL or 4XL has to either pick the closest available option or write in a note that might or might not get seen.
Ask for preferred fit, not assumed size. A question like "What size would you order for a standard unisex tee?" with a range that runs XS through 5XL, plus a "prefer a women's cut" option if you're offering those separately, gives people room to answer honestly. You're not asking anyone to disclose their body. You're asking a logistical question about garment preference.
Some teams add a fit note: "We're ordering in [brand] sizing. Feel free to check their size chart at [link] before answering." That's a small addition that meaningfully improves data quality, because sizing varies enough across manufacturers that "large" in a Gildan 5000 and "large" in a Bella+Canvas 3001 are not the same garment.
The data you collect also tells you something about your workforce over time. If you're running annual apparel orders and you track size distributions year over year, you start to build a useful picture of where your ordering should be weighted. That's worth more than any generic size chart.
For teams navigating the broader question of inclusive sizing across different garment categories and gender-inclusive options, the Inclusive Sizing for Org Swag resource covers the topic in more depth. The short version: ask your team, offer the range, and stop treating the question as sensitive when it's actually just operational.
Company apparel that fits everyone costs slightly more and sends a message worth the difference.
