MLB jersey size guidance
Looking for a MLB jersey size chart? We have not been able to open and confirm a current numeric chart for MLB jerseys from the maker or the official league shop, so we do not publish numbers for it. Inventing or averaging sizes would be worse than saying so. What we can give you is how to measure, how MLB fit tends to differ by tier, and where to find the maker's own chart.
| Situation | What to do |
|---|---|
| You know your chest measurement | Open the maker's chart on the listing you plan to buy and match your number to its row. |
| Between two sizes | Smaller for a closer fit, larger for a looser fit or layers. |
| Buying for a gift | Measure a jersey or shirt that fits well, lay it flat and compare it with the listing's own garment measurements if shown. |
| Different tier than your last jersey | Check the new tier's chart; cuts differ between tiers. |

Frequently asked questions
What size MLB jersey should I buy?
Measure your chest, then match it to the maker's own chart on the listing for the exact jersey you want. We do not publish MLB numbers we cannot confirm.
Are jerseys true to size?
Not always. Fit depends on the maker and the tier: on-field style cuts tend to be closer to the body and fan versions looser. Use the maker's own chart for the exact product, and size up if you plan to layer.
How do I measure my chest for a jersey?
Wrap a soft tape measure around the fullest part of your chest, under the arms and across the shoulder blades, keeping it level. Breathe out normally and do not pull the tape tight.
What if I am between two sizes?
Nike's guidance is to order the smaller size for a tighter fit or the larger size for a looser fit. If you want to layer a hoodie or thermal shirt underneath, take the larger one.
Is a size chart a body chart or a garment chart?
The charts on this site are body measurements, as published by the maker. Some retailers publish garment measurements instead, so never mix numbers from two different charts.
Do MLB jersey sizes differ between tiers?
Often, yes. Tiers can be cut differently, and a closer-fitting tier may need a size up. Check the chart that applies to the tier you are buying.
Does this tool store my measurements?
No. The finder runs entirely in your browser; your numbers are not sent anywhere, saved or shared.
