Youth softball jersey sizes follow chest measurements, not age, so measure the fullest part of the chest and match it to the brand’s chart.
Buying a youth softball jersey without a size chart is a gamble. Youth softball jersey size chart confusion usually comes from one thing: brands measure differently. A Youth Large from one manufacturer can run two inches smaller than another’s, so the same player can wear different sizes depending on the uniform company. The fix is simple: measure the player’s chest, then match that number to the chart for the specific jersey brand you’re ordering from.
How To Measure For A Youth Softball Jersey
Take measurements while the player wears light clothing and stands naturally. Run the tape measure under the arms, around the fullest point of the chest, keeping it level across the back. That chest number is the one that matters most for jersey fit.
Waist and hip measurements matter if the uniform includes pants or a fitted style. For the waist, measure around the natural waistline, usually just above the belly button. For hips, wrap the tape around the fullest part. If pants come with the uniform, check whether they’re knicker-length or full-length — inseam depends on style, not waist size.
Pro tip: when the player falls between two sizes, opt for the larger one. A looser fit is more comfortable for swinging and throwing, and the chart’s numbers are minimums, not exact fits.
Youth Softball Jersey Size Chart By Brand
Size bands are only useful when tied to the brand you’re actually ordering. Below are two common reference charts to show how much they can differ.
| Size Label | Chantilly Youth Softball (Chest) | Boombah Fastpitch (Chest) |
|---|---|---|
| Youth Small | 26–28″ | 28–30″ |
| Youth Medium | 28–30″ | 30.5–32.5″ |
| Youth Large | 30–32″ | 33.5–35″ |
| Youth XL | 32–34″ | 35.5–38″ |
| Adult Small | 34–36″ | 38.5–41″ |
| Adult Medium | 38–40″ | 41.5–44″ |
That gap between charts tells the real story. The Chantilly Youth Softball size chart pairs a Youth Large with a 30–32″ chest, while Boombah’s fastpitch custom uniform sizing puts that same chest range at an X-Small. Ordering without checking the specific chart means guessing.
Because the same letter size maps to different numbers depending on the manufacturer, always check whether a chart says youth, women’s, or adult before you pick. A women’s cut fits differently than a youth cut even at the same chest measurement.
Common Youth Softball Jersey Sizes
Most youth softball programs use YXS, YS, YM, YL, and YXL labels, though some use numbered ranges like 4-6, 6-8, 10-12, and 14-16. Both systems work the same way: they map to chest measurements, not age brackets. Age is a starting point at best, never the deciding factor.
Two more details matter when ordering as a team. Screen printing and tackle twill need flat space, so a size that fits correctly still may affect where numbers sit. Youth softball jerseys commonly use 3-inch front numbers and 6-inch back numbers, and a snug jersey can cause decoration to look cramped.

FAQs
Should I size up in youth softball jerseys?
Yes, when a player measures between sizes, choose the larger option. Jersey measurements are minimum chest sizes, and a bit of extra room improves comfort during play. A 42-inch chest matched to a 42-inch uniform can still fit tight because the chart number doesn’t account for movement or layered clothing underneath.
What if my daughter measures between youth and adult sizes?
It depends on the brand’s cut. Some charts bridge youth and adult sizes with an Adult Small at 34–36 inches, while others use a girls’ or ladies’ label for the same range. Check which chart the uniform company uses, and when in doubt, choose the larger size for comfort and room to grow.
Why do size charts differ so much between brands?
Each manufacturer designs its own cut and fit, and there’s no standardized federal sizing for youth softball jerseys. One brand’s Youth Large may measure 30–32 inches while another’s starts at 33.5 inches. That’s why the same player can wear a different size depending on the uniform supplier.
