Choosing an MLB jersey size is easier when you compare garment measurements instead of relying only on the size printed inside a T-shirt. Baseball jerseys can be worn over a thin shirt or another layer, and the available size range can vary by product. This guide explains how to measure, how much room to allow and what to confirm before ordering sizes S–6XL.
Start with the exact product page
Use the size selector on the exact listing you plan to buy. Do not assume that every item in the MLB jersey directory carries the same sizes or uses identical measurements. For example, the Men’s Dodgers #17 Shohei Ohtani Blue stitched baseball jersey currently lists men’s S, M, L, XL, 2XL, 3XL, 4XL, 5XL and 6XL. Other styles may offer a different range.
How to measure a jersey that already fits
Choose a jersey, button shirt or similar garment with the fit you want. Lay it flat without stretching the fabric. Smooth the body and sleeves, then take these measurements:
- Chest width: Measure straight across from armpit to armpit. Double this number only if you need a full chest circumference for comparison.
- Body length: Measure from the highest shoulder point near the collar to the bottom hem.
- Shoulder width: Measure across the back from one shoulder seam to the other when this measurement is available for the product.
- Sleeve length: Measure from the shoulder seam to the sleeve edge if sleeve coverage matters to you.
Use the same unit throughout the comparison. Measuring in both inches and centimeters can create avoidable errors if a number is copied into the wrong column.
Allow room for the way you will wear it
A jersey worn over a thin T-shirt needs less extra room than one worn over a hoodie. Decide whether you prefer a close, regular or loose fit before choosing a size. If your reference garment already fits the way you want, matching its flat chest width and length is usually more useful than choosing from height or weight alone.
If your preferred measurements fall between two available sizes, consider the larger option when you want layering room or easier movement. Consider the smaller option only when its confirmed garment measurements still allow the fit you want. The product name alone—such as “Men’s,” “Limited,” “Flex Base” or “stitched”—does not provide enough information to predict fit.
Choosing S–XL
For S, M, L and XL, shoppers often make the mistake of copying their everyday T-shirt size. A baseball jersey may have a different length, chest shape or intended layering room. Compare a garment you own with the size information for the specific listing. Also check that the selected variation shown in the cart matches the size you intended to choose.
Choosing 2XL–6XL and big-and-tall sizes
Extended-size buyers should check both chest width and body length. Moving up a size can add width and length, but the amount may vary by style. Do not assume that a 4XL, 5XL or 6XL in one jersey will match the same label in another listing.
Confirm that the size is selectable on the product page before payment. The Ohtani jersey linked above currently shows options through men’s 6XL; it does not currently show 7XL. If you need a size not displayed, contact customer service through How to Order and ask for current availability rather than selecting a substitute size.
Stitched construction and fit
Stitched names, numbers and team elements describe how visible details are applied; they do not guarantee a particular fit. Review the product description and images for construction details, then use measurements for sizing. Do not infer the construction or dimensions of one jersey from photos of a different item.
Custom name and number orders
For a custom order, send the exact style, color, size, name spelling, number and quantity in writing. Confirm the garment measurements and production method before payment. Personalized items may have different return restrictions, so check every character and size carefully before approving production.
Shipping and returns
Size availability, preparation time, destination and shipping method can affect the delivery estimate. Review the site’s Shipping Policy and request an order-specific estimate if you need the jersey for a game, trip, gift or event. Carrier and customs delays can affect estimated transit times.
Before removing tags or wearing the item, inspect the received size and visible details. If an item arrives damaged, defective or materially different from the confirmed order, follow the Returns & Refunds policy and provide the requested order information and clear photos. Do not return an item without written authorization.
MLB jersey size checklist

- Measure a garment that already fits the way you prefer.
- Compare flat chest width and body length using the same unit.

- For 2XL–6XL, verify width and length instead of relying on the label alone.
- Confirm custom text, construction, preparation time and return terms in writing.
Frequently asked questions
Do MLB jerseys run big?
There is no reliable answer for every product. Compare garment measurements for the exact style with a jersey or similar garment that fits you well.
Should I size up for a hoodie?
You may need more room when wearing a jersey over a hoodie. Measure the reference garment over the intended layer or compare its flat chest width with the product measurements before ordering.
Are 4XL, 5XL and 6XL available?
The linked Ohtani Dodgers jersey currently lists men’s 4XL, 5XL and 6XL. Other products can have different options, so check the size selector on each listing.
Is 7XL available on the Ohtani jersey?
7XL is not currently shown in that product’s size selector. Ask customer service to confirm other available styles if you require 7XL.
