Inch-accurate sizing charts across the 10 most-used US blank brands, plus how to measure, handle fit variance, and avoid the S/M/L reorder loop.
Unisex sizes are cut on a men's pattern, so a women's medium is roughly a unisex small and a women's large is roughly a unisex medium. Use the converter above for exact letter-to-letter conversions across all six directions, then check the inch ranges in the table below to confirm chest, waist, and hip fit.
How unisex sizing actually differs from women's
Unisex apparel is built on a men's body block. That sounds technical, but it shows up in four real ways when a woman wears the same letter size in unisex versus women's.
- Shoulders run wider. A unisex medium has shoulders cut for a 17 to 18 inch shoulder span. Women's medium is usually 14 to 15 inches. Unisex tees often look "off the shoulder" on women.
- Torso runs longer. Unisex body length adds 1 to 2 inches versus the women's equivalent letter size. This is great for tucking, less great for cropped silhouettes.
- Hips run narrower in proportion. Women's blocks add hip flare. Unisex blocks do not. A women's size large with an athletic hip will sit cleaner in unisex.
- Sleeves run longer. Add roughly half an inch to one inch of sleeve length per letter size up.
If you want a tailored women's fit, drop one size from your women's letter for unisex. If you want a relaxed boyfriend fit, keep your women's letter size. Most of our customers ordering team uniforms want consistency across mixed-gender teams, which is the case the unisex cut was built for. Read our body measurement guide to lock the right size before you order in bulk.
Inch-by-inch chest, waist, and hip ranges
Letter sizes are a shortcut. Inch measurements are the truth. Here are the inch ranges we use on real Arklavo quotes for unisex tees, polos, and crewnecks, anchored to ASTM body-measurement standards.

|---|---|---|---|---|
| XS | 31 to 34 | 25 to 28 | 31 to 35 | S |
| S | 35 to 37 | 29 to 31 | 35 to 37 | M |
| M | 38 to 40 | 32 to 34 | 38 to 41 | L |
| L | 41 to 43 | 35 to 37 | 41 to 44 | XL |

Men's to women's (cross-gender shopping)
Men's apparel matches unisex one-for-one in most US blank brands. Convert by sizing up one letter for the women's equivalent. Men's M is women's L, men's L is women's XL, and so on.
When to size up or size down on unisex apparel
We process a lot of bulk orders where one size guide has to work for a mixed-gender team. These are the situations where we tell buyers to size up or down before the order locks.
- Size up if the wearer has a chest above 38 inches and wants room across the bust.
- Size up if the order is for a relaxed or oversized aesthetic (think band merch, hospitality staff shirts).
- Size down if the wearer wants a tailored women's silhouette (the unisex shoulder will still run wide; pair with darts if needed).
- Stay at converted size for athletic builds and athleisure where the longer torso reads as intentional.
- Order one size sample when the team spans 20 to 50 people. We send a free sample on bulk quotes so the size run is locked before production.
See our T-Shirt Size Chart for brand-by-brand variance across the 10 most-used US blanks. Polo sizing and hoodie sizing run on slightly different blocks; check those tools before placing those orders.
Frequently asked questions about unisex sizing
What is a women's medium in unisex?
A women's medium converts to a unisex small in most US apparel brands. Women's medium chest range is 36 to 38 inches; unisex small chest range is 35 to 37 inches. Expect a slightly wider shoulder and longer torso on the unisex cut.
What is a women's large in unisex?
A women's large converts to a unisex medium. Women's large chest range is 39 to 41 inches; unisex medium chest range is 38 to 40 inches. The unisex medium will fit the bust well and run slightly longer in the body.
What is a unisex large in women's?
A unisex large converts to a women's extra large. Unisex large chest range is 41 to 43 inches; women's extra large chest range is 42 to 44 inches. Wearers who prefer a women's tailored cut should size down to a unisex medium.
What size is unisex medium?
Unisex medium fits a chest of 38 to 40 inches, a waist of 32 to 34 inches, and a hip of 38 to 41 inches. It is the equivalent of a men's medium and a women's large in most US blank brands.
Does unisex run bigger than women's?
Yes. Unisex apparel is cut on a men's pattern, so the same letter size will be wider in the shoulders and longer in the torso than the women's equivalent. A woman ordering unisex should size down one letter for a tailored fit or stay the same for a relaxed fit.
What is the difference between unisex and gender neutral sizing?
Unisex and gender neutral refer to the same sizing concept: one pattern that fits people of any gender. The most common cut is built on a men's body block. Nike calls their version "gender neutral (men's based)," which is the same as unisex.
Should I order unisex or women's for my team uniform?
Order unisex when your team spans mixed genders and you want one consistent silhouette. Order women's when the team is all-women and you want a tailored fit through the bust, waist, and hip. We process both on bulk Arklavo orders with no minimum.
How do I measure my chest for unisex sizing?
Wrap a soft tape measure around the fullest part of your chest, under the arms and across the shoulder blades, parallel to the floor. Keep the tape snug but not tight. Compare the inch measurement to the chest column in the table above to find your unisex size.
Are men's and unisex sizes the same?
In most US apparel brands, yes. Men's medium and unisex medium share the same chest, waist, and shoulder measurements. Some brands offer a slightly trimmer men's fit and a slightly wider unisex fit, so always check the brand's spec sheet before bulk-ordering.
What unisex size am I if I am a large in women's?
If you are a large in women's, you are a unisex medium for a tailored fit or a unisex large for a relaxed fit. The exact answer depends on whether you prefer the bust to sit close (size down) or skim (size up). Most buyers go unisex medium.
