Boston Celtics Jerseys, Tees & Hoodies — S-6X, XLT-5XLT
Some looks in sports never change, and the green and white is one of them. This page gathers Boston Celtics big and tall apparel — Celtics jerseys, tees and hoodies in the extended sizes.
The men’s run goes S, M, L and XL, then steps into 2X, 3X, 4X, 5X and 6X, and the tall cuts run XLT through 5XLT, so the tall fan gets length built in instead of a wider shirt that still rides short.
Every size has its own link below, and the women’s and kids’ departments sit in the closing section.
Because plenty of Boston fans shop price-first — cheap Boston Celtics jerseys and Celtics gear on sale are heavily searched phrases — the shopper questions at the bottom take the deals question head-on.

Boston Celtics Jersey — the Green and White Icon
The jersey is the icon: “Celtics” arched across the chest, the green that has meant the same thing for generations, and a look that has barely needed changing in decades. It is the piece Boston fans reach for first, at the Garden and everywhere else.

Celtics Sizing — Extended Sizes and Tall Cuts, Explained
Here is the men’s range laid out plainly. The regular sizes run S, M, L and XL, then step into the extended sizes: 2X, 3X, 4X, 5X and 6X — the full 3X–6X range this site exists for. The tall cuts run XLT, 2XLT, 3XLT, 4XLT and 5XLT.
Every size below is its own link into the men’s Celtics department, already filtered to that fit, so a 4X fan or a 3XLT fan lands on their size instead of scrolling past shirts that stop at XL:
One naming tangle worth clearing up before you click: the stores label the same fits different ways. A Celtics jersey listed as 4XL at one store is the 4X here and the 4XB at another — same shirt size, three spellings. The translations for the whole run:
- XXL = 2X = 2XL = 2XB
- 3XL = 3X = 3XB
- 4XL = 4X = 4XB
- 5XL = 5X = 5XB
- 6XL = 6X = 6XB
- XLT = XT = LT
- 2XLT = 2XT
- 3XLT = 3XT
- 4XLT = 4XT
- 5XLT = 5XT
So if a store filter only shows 4XB, that is your 4X. And if your closet tag says 3XL, shop the 3X links here with confidence.
Two fit notes before you order. First, a tall cut and a bigger size are not the same thing: sizing up adds width through the chest and shoulders, while an XLT-range cut adds the length through the body and sleeves.
If your jerseys ride up when you stand for a timeout, the tall cut is the fix, not another X.
Second, basketball jerseys are cut loose for layering — over a tee most nights, over a hoodie on a cold walk back to the T. If you plan to wear yours over a sweatshirt, the extra room of one size up is the comfortable call.
One honest note on stock: Celtics sizes come and go — availability can fluctuate with stock levels and the season, and the extended sizes tend to move first when the team is winning.
That’s why the links on this page open the full Celtics departments rather than a single jersey: if the exact one you want is picked over in your size, every other Boston option in your fit is right there in the same view.
Interesting Facts About the Celtics
Start with the number nobody else can touch: 18 NBA championships, the most of any franchise, the latest of them in 2024.
The standard was set early — the Bill Russell teams won 11 titles in 13 seasons, a run so far beyond normal that every dynasty since gets measured against it and comes up short. Boston fans do not say that quietly, and the banners hanging over the court back it up.
Home is TD Garden, and the most famous thing in the building is under everybody’s feet: the parquet floor, a patchwork of wood panels that is as much a part of the team’s identity as the uniforms.
The green-and-white look itself has barely changed in decades — no rebrands, no alternate colour scheme chasing a trend — which is part of why a Celtics jersey never looks dated. The mascot working the aisles is Lucky the Leprechaun, dunking off a trampoline between quarters.
Boston Celtics Apparel — Shopper Questions
Do Boston Celtics jerseys come in big and tall sizes?
Yes — that’s the point of this page. Celtics jerseys and apparel run through the regular sizes into 2X, 3X, 4X, 5X and 6X, with tall cuts from XLT through 5XLT, each on its own link in the size list above.
Whatever spelling your closet uses — 4X, 4XL or 4XB — every size has its own link in the size list above, filtered straight to your fit. The women’s range and the kids’ department are linked in the closing section.
Is 4X the same size as 4XL or 4XB?
Yes — same fit, three labels. Stores just print it differently: one shop’s Celtics jersey 4XL is another’s 4XB jersey and this page’s 4X.
The pattern runs through the whole range. 2X = 2XL = 2XB, 3X = 3XL = 3XB, 5X = 5XL = 5XB, and 6X = 6XL = 6XB. The tall cuts translate too: XLT = XT, 2XLT = 2XT, 3XLT = 3XT, 4XLT = 4XT, 5XLT = 5XT.
So when a store’s size filter shows only 4XB or 3XT, you are still looking at your size — it did not disappear, it just changed its name tag.
What’s the difference between 3X and 3XLT?
Length. The 3XLT carries roughly the same room through the chest and shoulders as the 3X, with extra length added through the body and sleeves. Tall fans generally fit better in their tall size than in a regular size up — sizing up buys width first.
Is there women’s Celtics gear in plus sizes?
Yes — the FansEdge women’s Celtics department in the closing section carries the ladies’ range in women’s cuts, including the plus sizes, and the Fanatics department covers women’s gear alongside the men’s.
Where can I find cheap Boston Celtics jerseys in big sizes?
Start with the size list above — that’s where the deals live. Celtics jerseys on sale and clearance styles rotate through the same big and tall departments linked on this page, so the size link that finds your 4X or 5XLT also surfaces whatever is marked down in it.
Fanatics and FansEdge run different sales on different days, and a jersey discounted at one store is often full price at the other, so checking both is the easiest way to pay less.
One warning: sale stock in the extended sizes goes first, so a discount in your size rarely waits around.
Is a Celtics jersey a good gift for a Boston fan?
It’s one of the safest gifts in basketball. The green and white never dates, the jersey is the piece Celtics fans reach for first, and with sizes running to 6X and tall cuts to 5XLT, the bigger or taller fan on your list gets one that actually fits.

FansEdge keeps its own full Celtics departments, and the two stores stock and restock on their own schedules — worth a quick look at both before you check out, especially in the extended sizes where one store’s 5X can be gone while the other’s is sitting there:
