A baseball jersey is one of the easiest ways to look game-day ready, but the fit can be confusing. Jerseys are cut wider than a t-shirt, button down the front and are meant to be worn loose. So how should a baseball jersey fit? This guide covers the ideal fit for men and women, our full size chart and simple tips for choosing between sizes.
How Should a Baseball Jersey Fit?
- Chest: roomy and comfortable, with the buttons lying flat. You should be able to wear a t-shirt underneath without the jersey pulling.
- Shoulders: the seam sits at or slightly past the edge of your shoulder.
- Length: the hem falls around your hips so it can be worn untucked over jeans or joggers.
- Sleeves: short sleeves end above the elbow and sit away from the arm.
In short, a baseball jersey should look relaxed, not tight like a performance shirt and not so big that it hangs like a dress.

To compare with a shirt you own, measure its chest flat from armpit to armpit and double the number. Kids’ sizes from toddler 2T to youth XL are listed on our size chart.
Choosing a Size for Men
- Order your usual t-shirt size for a classic, relaxed jersey fit.
- If you plan to layer it over a hoodie, size up once.
- If you want a cleaner fit for wearing buttoned up, compare the bust with a button-up shirt that fits you well.
Choosing a Size for Women
- Our baseball jerseys are unisex, so they run larger than women’s tops.
- Go one or two sizes down from your usual women’s size for a fitted look.
- Keep your usual size for an oversized jersey to wear open over a crop top or tied at the waist.
How to Wear a Baseball Jersey
- Open over a tee: unbutton it over a white or black t-shirt with jeans and sneakers.
- Buttoned up: wear it as a shirt with cargo pants or shorts for a sporty streetwear look.
- Finish with a cap: a trucker hat or baseball cap completes the game-day outfit.
Frequently Asked Questions
Do baseball jerseys run big?
They are designed with a loose fit. Use the bust measurement rather than your usual size label if you are unsure.
Should you size up in a baseball jersey?
Size up only if you want to layer it over a hoodie or prefer a very oversized look.
Can I wear a baseball jersey with nothing underneath?
Yes. Buttoned up, it works as a short-sleeve shirt, especially in summer.
