Size Guide

Everything below is the garment measured flat, not your body. Chest is the full width from armpit seam to armpit seam; length runs from the highest shoulder point down to the hem. Fastest way to get it right: take a jersey that fits you well, measure it the same way, and match the numbers.

Men's / Unisex Big & Tall Authentic (numbered) Youth Preschool / Toddler Women's
Diagram: measure straight across the chest from armpit seam to armpit seam, and from the top of the shoulder down to the hem
ChestLay the jersey flat and measure straight across, from one armpit seam to the other. That full width is the number in the chart - so a chart reading of 44 in means the shirt measures 44 in across, not a 44 in body.
LengthFrom the highest point of the shoulder straight down to the bottom hem, with the jersey laid flat and smoothed out.

Men's / Unisex Jerseys

XS - 5XL

The default cut for most of the store. Loose through the body by design, with a straight hem.

Authentic - Numbered Sizing

36 - 64

Some Authentic styles are sold by number instead of letter. The number is the chest width in inches - so a size 48 measures 48 in across. Use the letter column to translate your usual size.

Number Equals Chest (in) Length (in) Chest (cm) Length (cm)
36 XS 36 29 91 74
40 S 40 30 102 76

Youth Jerseys

S - XL

Cut in the same shape as the adult shirts, just scaled down. Age is a guide only - chest measurement is the reliable one.

Size Age Chest (in) Length (in) Chest (cm) Length (cm)

M 9-10 yrs 30-32 23 76-81 58

XL 13-14 yrs 34-36 26 86-91 66

Preschool & Toddler

2T - 7 / 12M - 24M

Worded by age rather than letter on purpose - this is the range where children grow fastest, so measure a shirt that fits today and match the chest.

Size Age Chest (in) Length (in) Chest (cm) Length (cm)

01
Cut for comfort

Basketball jerseys are meant to hang loose. If you want a regular, closer fit, order one size below your usual.

02
Between sizes?

Go up. The extra room is how the cut is designed to be worn, and it layers over a hoodie in winter without pulling.

03
Compare, don't guess

Match the numbers to a shirt you already own rather than to your body. Printed names and numbers on the back do not change the fit.

Numbers are taken flat and can vary by roughly 1 in / 2 cm between styles, and Youth overlaps Preschool at age 7 - in that case Youth S is the slightly longer of the two. Still unsure? Contact us with your height, usual size and the jersey you are looking at, and we will tell you which one to take.

Description

Kit for the school run and the driveway, in Boston Celtics Green — comfortable enough that it gets worn out, not worn out early.

This is the jersey for the nights that run long: tip-off on the couch, a watch party that spills into overtime, or a summer run where the colours still read clearly under the lights. It reads as Boston Celtics from across the room and as Jayson Tatum up close. Name and number are sealed to the mesh in layers, with an edge you can feel with a fingertip.

Fabric is 100% recycled polyester with a moisture-wicking treatment — light, quick-drying and low-fuss. V-neck, taped interior, no scratchy label — the details are small and they add up over an evening. The design is restrained enough for everyday wear and loud enough for game day, which is a difficult balance. The Green sits comfortably next to older Boston Celtics pieces if you already have a collection going.

Why it earns its keep

  • Claims-proofOne name and number, applied so it does not peel after a term.
  • Built for a dateFirst season, birthday, graduation — the personalisation carries the occasion.
  • Matches the grown-upsSame colours as the adult range, so family photos line up.

What comes up most

Is it comfortable straight away?

Yes — there is no breaking-in period, and the taped neckline keeps the inside smooth.

Can I order more than one with different names?

Yes — each personalised piece is produced separately, so different names and numbers are fine.

Can I see the lettering before it ships?

The lettering follows the details entered at checkout, produced in the same finish as the team graphics.

Is it warm enough for winter?

On its own it is a summer-weight shirt; over a long-sleeve tee it works through the colder months.
