NCAA Size Guide — Complete Unified Chart

Sizing help

One chart. Every size.

Every measurement we publish, in a single table: body measurements and finished-garment measurements, inches and centimetres, across men’s, women’s, youth, toddler, infant and preschool. Read your row, and if the chart leaves any doubt, send us your numbers and we will check them before your parcel is packed.

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.

One chart, split by fit

The size blocks

The chart is split into six independent blocks, one for each fit group. Men and women are in separate blocks with separate tables, and each block only carries the measurements that actually exist for that fit — a men’s block never shows a bust column, 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, and never a value that failed to load.

Men

Men’s & unisex

Body chest is the measured value that decides the size. Waist and body length are reference values. Garment chest, length, sleeve and shoulder are the finished measurements of the jersey itself.

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 units — body and garment alike — so no column is left in a single unit. Original figures are never rewritten or re-rounded.

How much error to allow

Tolerances to allow for, and why each one exists.

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

On the size band edges — each size covers a range, not a single value, and the ranges butt directly up against each other with no overlap. If your measurement lands within an inch of a boundary, treat the two sizes as genuinely borderline rather than picking one on the dot.

The youth age bands

Youth, toddler, infant and preschool sizes are sold on an age band printed on the product. The standard size chart carries a slightly different band for a few youth sizes, so both are shown side by side. The published band is the one we ship and sell — it is the one that decides the size.

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

Where the numbers come from

Data source

Every figure in the chart is one of three kinds, and we label which is which rather than blending them together.

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.

One real gap in the source sizing. 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. It is flagged in the chart rather than smoothed over, so the jump is not read as a typo.

Which block to read

Applicable scenarios

The same chart is used for every sport in the range, so one table covers all of them. The size run a specific sport offers can be narrower than the full block below, so check the size list on the product page before ordering.

If you are buying	Read this block	Decided by	Then confirm with
Men’s jersey, any sport	Men’s & unisex	Body chest	Waist and body length confirm the cut. Garment chest, length, sleeve and shoulder tell you how the jersey itself fits.
Women’s jersey	Women’s	Body bust	Waist and hips confirm the cut. Note the real gap between XXL and 3XL, flagged in the chart.
Youth jersey	Youth	Published age band	Body chest and body length confirm it. A published age band always wins over the reference chart.
Toddler jersey	Toddler	Published age band	Body chest confirms it.
Infant romper or tee	Infant	Published age band	Body chest confirms it.
Preschool jersey	Preschool	Published age band	Body chest confirms it.
Between two sizes	Same block	The larger size	Room reads better than a pull. The step-up column shows how much room you gain.
Oversized or boxy fit	Same block	One size up	If you want the loose game-day cut, take the next size up in the same block.

The questions we get weekly

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.

The same chart, by sport

Size charts by sport

The measurements do not change with the sport — every jersey in the range is cut to the same size chart. What changes is what each sport stocks. Every sport below carries its own chart, built from the sizes that sport is actually sold in, so a size that is not offered is simply not listed rather than shown as an empty row.

Which sport stocks what

The size run each sport carries, group by group. A cell with nothing in it means that group is not stocked for that sport.

Every size in these charts is the same size you will find in the unified chart above — body chest, bust, waist, hips, body length and every finished-garment measurement, in inches and centimetres. Only the size run differs from sport to sport.

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.

NCAA Baseball Fan Jersey

#1 BYU Cougars Youth Lightweight Baseball Jersey - White

White

There is a particular kind of pride in wearing BYU Cougars colours somewhere far from home. This jersey carries it well.

This White BYU Cougars Fan Jersey takes the look supporters recognise from game day and turns it into something you can wear on a normal Tuesday. The shape is relaxed, the fabric breathes, and the team colourway reads clearly from across a room.

Club identity

For Cougars fans, the details matter - the shade of white, the shape of the numbers, the way the crest sits. This jersey keeps those details intact.

Club: BYU Cougars (NCAA baseball)
Gender / fit: Youth (kids)
Version: Fan fan build
Colourway: White
Sizes: Multiple sizes available - see the size options on this page

This listing is the Youth (kids) version, cut and graded for kids and teenagers.

The people wearing it

Nobody buys a college shirt for the sport itself, so the content that works is narrow: start from the school, then build around campus life. The buyer is usually a student or an alumnus, and the shirt is worn far more often outside the stadium than in it.

Audience: students on campus, alumni and parents of players
Why people buy it: school identity, alumni events and campus sports
When it gets worn: campus week, homecoming, alumni weekend, game day
Where this range sits: NCAA is the most fragmented of the four, so club loyalty matters more here than anywhere else on the shelf.

Details that matter when choosing this BYU Cougars jersey

The BYU Cougars Fan jersey is the base piece of the Cougars range: the same team colourway, number placement and lettering fans expect, cut in a shape you can wear all day.

Start from the BYU Cougars jersey and the rest of the choice narrows quickly: BYU Cougars colours, team styling, and a cut that works with jeans as easily as with shorts.

Filed under NCAA baseball jersey, this sits inside the NCAA side of the store, so it is filtered and compared against the rest of the NCAA range rather than the general baseball category.

The Cougars college jersey buyer is usually buying for a specific occasion rather than browsing, so the useful details here are the fit, the fabric and how the colour looks outside the stadium.

If you are shopping NCAA fan gear, the deciding factors are usually fit and occasion rather than specifications: this one is a relaxed fan for kids and teenagers, cut to be worn regularly instead of once a season.

Where to wear it

Kickoff, tip-off, first pitch - it does not matter which. This is the shirt that comes out when the BYU Cougars play.

Name, numbers and team detailing applied for a flat, smooth finish
Full-button front
Easy to pack and quick to dry - good for travel and away days
Imported

How it feels

The hand feel is soft rather than slick - closer to a well-worn tee than to a technical shell.

Sizing for younger fans

Sized for younger fans with a little room to grow, because nobody wants to buy a jersey twice in one season.

Design notes

Bold white colourway that photographs well and stands out in a crowd.

Questions people ask about this BYU Cougars jersey

What size and fit is the BYU Cougars fan?: It is a relaxed supporter fit graded for kids and teenagers, with sizes listed on this page. Measure against the garment, not a generic size chart.
What material is the BYU Cougars jersey made from?: A lightweight breathable polyester knit, which is what keeps it comfortable through a full game day and easy to wash.
What colour is the BYU Cougars fan?: The colourway is white.
How should I care for the BYU Cougars jersey?: Cold machine wash inside out, hang to dry, and skip the tumble dryer - heat is what cracks printed lettering.
What exactly is the BYU Cougars Fan Jersey in White?: It is a fan-version baseball jersey inspired by the BYU Cougars on-field look, offered in the white team colourway. It is made for supporters to wear on game day, at training or as casual clothing, not as match-worn kit.
Is this a match-worn or player-issue jersey?: No. This is a fan made for supporters: a relaxed cut and everyday comfort rather than the heavy technical build players wear. It follows the BYU Cougars look in colour and layout, but it is not on-field kit.
