Arizona State T-Shirt Sizing Guide | Fit It Right The First Time

Getting the right fit for an Arizona State University t-shirt means matching your body measurements to the specific size chart for that shirt model, not guessing based on your usual size.

A perfect-fitting ASU tee starts with a tape measure, not a favorite old shirt. The sizing you need depends on whether you’re buying a men’s or women’s cut, and even the specific product page has the final word. Here’s how to nail the size so your Sun Devils gear actually fits.

How to Take Your Body Measurements for an ASU T-Shirt

Grab a flexible tape measure (or a piece of string and a ruler) and measure your body, not the shirt you already own. For the chest measurement, wrap the tape around the widest part of your chest, keeping it level across your back. For the waist, measure just above your belly button, where the shirt’s hem will naturally fall. A second person can make those numbers more accurate. Keep the tape snug enough to stay in place, but never tight enough to compress the skin — that gives a false smaller reading.

ASU Men’s T-Shirt Size Chart (S–XXL)

Men’s t-shirts sold through USAMM are sized by chest and waist measurements. Match your body numbers to the tightest fit you want, not a looser “comfortable” guess.

If you measure a 40-inch chest, you land between M (39.75″) and L (41.75″). Go with the larger size if you prefer a relaxed fit; stick with the smaller for a trim look.

ASU Women’s T-Shirt Size Chart (S–XL)

Women’s ASU t-shirts are measured by body length and width, not chest and waist — a critical difference shoppers often miss. The length runs from the highest shoulder point to the hem, and the width is the straight measurement across the chest, 1 inch below the armhole.

Women’s shirts run fitted, so if you are between sizes on the width measurement, sizing up prevents an overly tight chest. And yes, always check the product page’s own chart — this particular chart comes from USAMM’s general sizing guide, but the exact shirt model can vary.

Common Sizing Mistakes That Ruin the Fit

Three errors trip up most ASU shoppers. First: using a shirt you already own as a template. That shirt may have shrunk, stretched, or been cut differently than this new tee — your body is the only reliable reference. Second: measuring the waist too low, below the belly button, which gives a too-small reading. The shirt’s hem sits at the natural waist, just above the navel. Third: ignoring that women’s tees are charted by length and width, while men’s use chest and waist. They are not interchangeable systems.

For caps and hats, measure around your head about 1 inch above the eyebrows. A 22-inch measurement fits a size 7; 23.5 inches fits 7.5; 24 inches fits 7.625; and 24.375 inches fits 7.75. That chart, like the shirts’, may vary by specific product model.
