Order first, check second. Torn between two rows? Order the size you lean towards, then email your height, chest and waist to fanservice2026@outlook.com. We compare your numbers against this chart before the parcel is packed and swap the size if a different one fits you better. Nothing ships until we agree the size is right.

The tape, not the guess

How to measure

Ninety seconds with a soft tape measure settles what no amount of label-squinting will. Wear a single thin layer, stand the way you normally stand, and let the tape touch you without squeezing. No tailor’s tape? Use a piece of string, pinch where it meets, then lay it against a ruler.

Chest — the number that runs the showWrap the tape around the fullest part of your chest, straight under the armpits. Keep it level front to back and breathe normally — do not puff up, do not hollow out.

Waist — your fit-check numberMeasure at the narrowest part of your torso, usually just above the belly button. Tape snug, not cinched. The charts use it to confirm the cut, not to pick the letter.

Body lengthFrom the highest point of the shoulder next to your collar, straight down to where you want the hem to sit. Compare against the length column before committing.

SleeveShoulder seam to wrist bone with your arm slightly bent.

Gap rule: if your measurement lands between two rows, take the larger size. Room reads better than a pull.

Every size we stock

The size chart

The chart below is split into 2 independent blocks, one for each fit group we stock in Baseball. Each block carries its own table, its own column set and its own header — a men’s block never shows a bust column, and a youth block never shows a garment column. Every measurement is given twice, inches first and then its centimetre equivalent, so the two always agree. A cell with nothing in it means that figure is not published for that size; it is never a zero.

Reading the table

How to read the table

Two column groups do different jobs. Body measurement is you — the tape wrapped around you, and it is what picks the size. Garment measurement is the jersey — laid flat on a table, and it is what tells you how the finished piece sits. The two are never interchangeable, which is why the chest on the garment is larger than the chest on your body.

How each measurement is taken, and which sizes it applies to.

Measurement	How it is measured	Applies to
Body chest	Wrap the tape around the fullest part of your chest, straight under the armpits, level front to back. Breathe normally — do not puff up, do not hollow out.	Men’s, youth, toddler, infant, preschool
Body bust	Around the fullest part of the bust, keeping the tape level all the way round.	Women’s
Body waist	At the narrowest part of your torso, usually just above the belly button. Snug, not cinched.	Men’s, women’s
Body hips	Around the fullest part of the seat, feet together.	Women’s
Body length	From the highest point of the shoulder beside the collar, straight down to where you want the hem to sit.	Men’s, youth, toddler, infant, preschool
Garment chest	The jersey laid flat, measured straight across the chest, one inch below the armhole.	Men’s
Garment bust	The jersey laid flat, measured straight across the bust.	Women’s
Garment length	From the high shoulder point straight down to the hem.	Men’s, women’s
Sleeve	Shoulder seam to the end of the cuff, arm slightly bent.	Men’s
Shoulder	Seam to seam across the top of the shoulder.	Men’s, women’s
Garment width	Across the chest of the jersey laid flat, underarm to underarm.	Women’s
Step up	Not a measurement — the difference between this size and the next smaller size in the same block, on the deciding measurement. The smallest size in each block has no step-up value, so that cell is left blank.	Every block
Blank cells	A measurement that does not exist for that size group. Never a zero and never a missing value — hover any blank cell to see why it is blank.	Every block

Units

Inches are the published unit. Every centimetre figure is converted from the inch figure beside it at 1 in = 2.54 cm and shown to one decimal place, so the two always agree. Every measurement in the chart is given in both.

How much error to allow

A finished garment is cut and sewn, not moulded, so allow a little.

Measurement	Tolerance	Why
Body measurements	±0.5 in / ±1.3 cm	Tape position and how you breathe shift the reading
Garment measurements	±0.5 in / ±1.3 cm	Cut and sew variation between production runs
Size band edges	±0.25 in	You may sit just on a boundary
Manual measurement	1–3 cm / 0.4–1.2 in	Accepted industry range for hand-taken measurements
Length (hem)	±0.5 in / ±1.3 cm	Hem finish and drape shift the reading
Fabric stretch	2–4%	Polyester mesh gives slightly with wear

Measured, published, derived

Where the numbers come from

Every figure in this chart is one of three things, and the table says which. Nothing here is invented, and no published value has been rewritten.

Figure	Type	What it means
Body chest — men	Measured & published	The chest range printed on the product itself, across the whole catalogue.
Body bust — women	Measured & published	The bust range printed on the product itself, across the whole catalogue.
Age band — youth, toddler, infant, preschool	Measured & published	The age range printed on the product. Where the standard chart disagrees, the published band is the one we ship and sell.
US size / numeric	Reference	From the standard replica size chart. The men’s numeric size is the chest circumference in inches; the women’s runs 0–2 to 28–30; the youth figure is a US youth size.
Body waist, body hips, body length	Reference	Not published in our catalogue, so taken from the standard replica size chart.
Garment chest, bust, length, sleeve, shoulder, width	Reference	Finished-garment measurements from the standard replica size chart, in inches.
Men’s 5XL waist and body length	Extrapolated	The published run stops at 4XL, so these two are extended on the same curve and flagged est. in the chart.
Women’s 3XL–4XL waist and hips	Extrapolated	Extended on the same curve from the published run and flagged est. in the chart.

The youth age bands

Where the standard chart and the published band disagree, the published band is the one we ship.

Youth size	Published age band	Reference chart age band	Which one to use
XS	Not published	6–7	Reference only
S	8–10	8	Published
M	10–12	10–12	Published
L	12–13	14–16	Published
XL	13–15	18–20	Published

The questions we actually get

Sizing questions

Short answers to the sizing queries that fill our inbox. If yours is not here, email fanservice2026@outlook.com and we will sort it within 48 hours.

Do these charts use body measurements or garment measurements?

Both, kept in separate column groups. Body measurement is the tape wrapped around you. Garment measurement is the jersey itself, laid flat on a table. The column headers say which is which — Body measurement and Garment measurement.

Which measurement decides the size?

Body chest for men’s and youth, body bust for women’s, and the published age band for toddler, infant and preschool. Waist, hips, body length and the garment group confirm the fit rather than picking the letter.

Why do the two age columns disagree for youth?

We print an age band on every youth product, and that published band is the one we ship and sell. The standard chart carries a different band for a few youth sizes. Both are shown side by side so you can see exactly where they differ — and the published one always wins.

Is there a gap in the women’s chart?

Yes, and it is in the source sizing itself: the women’s bust scale runs XXL up to 48.5 in, then restarts at 3XL from 53 in. No published women’s size covers the band in between, so it is flagged rather than smoothed over.

What does the step-up column mean?

How much room you gain moving up one size in the same block. It is measured on the deciding measurement for that block — chest for men and youth, bust for women. The smallest size in each block has no step-up value, so that cell is left blank.

What does the est. flag mean?

That value is extrapolated, not published. It sits past the end of the published size run, extended on the same curve. Treat it as a guide rather than a catalogue figure.

Why are some cells blank?

Because that measurement genuinely does not exist for that size group — men’s jerseys are charted on chest rather than bust, youth jerseys are charted on chest rather than waist, and adult sizes are not sold on an age band. A blank cell is never a zero, and never a missing value. Hover any blank cell to see why it is blank.

I am between two rows. Up or down?

Up. Room reads better than a pull.

How accurate are the numbers?

Allow ±0.5 in (±1.3 cm) for hand-taken measurements. Half an inch either way is normal, not a wrong size.

Measure once, cheer all season.

The right size is one email away if the chart leaves any doubt.

How these numbers were built. Body chest, body bust and the age bands are the measured, published catalogue values carried on the product. Waist, hips, body length and every garment measurement are not published in the catalogue, so they follow the standard replica size chart and are marked as reference values throughout. Figures marked est. are extrapolated past the end of the published run. 1 in = 2.54 cm.

Original values are never rewritten. Inches are the source figures; centimetres are converted from them and shown to one decimal place so the two always agree.
