Stadium Bag Policy Guide: NFL, MLB and Arena Rules

By the Reserved Seat editorial teamUpdated October 1, 2026How we research

Pick your bag by venue type

For an NFL game, the bag that works is a clear plastic, vinyl or PVC one within 12 x 6 x 12 inches, or a one-gallon clear freezer bag, along with a clutch no larger than 4.5 x 6.5 inches in any color. That is the league-wide policy as posted by the NFL on October 1, 2026, the date this guide was checked. A backpack, a tote or a full-size purse will not get in.

Outside football, there is no single rule. Use this as a starting point, then confirm on the venue's own page:

NFL stadium: the clear bag and clutch above.
MLB ballpark: often a larger soft bag is fine, but backpacks are the item most often refused.
Indoor arena: expect the tightest limit of all. Some allow only a wallet-sized clutch, and several refuse clear bags outright.

Rules shift from season to season, and occasionally from one event to the next, so confirm the current policy on the venue's site before you leave.

The 12 x 6 x 12 standard, read closely

The NFL's page, read on October 1, 2026, lets you carry:

One clear bag of plastic, vinyl or PVC within 12 x 6 x 12 inches . Clear cinch bags, fanny packs and backpacks count, as long as they fit.
A resealable one-gallon freezer bag instead, if it is clear.
A clutch on the side, strap or no strap, within 4.5 x 6.5 inches and in any color.
A logo on one side only. Buckles, grommets or decorations that hide the contents are not allowed.
Medically necessary items, after inspection, typically through one gate set aside for them.

Things you wear or pocket, like a neck-strap camera or a pair of binoculars, are not treated as bags. Some stadiums print the size as 12 x 12 x 6 inches; the dimensions are simply listed in another order. Read the exact text on the NFL's clear bag policy page.

Stadiums that tighten or tweak the NFL rule

Security enforces the stadium's own list, and some lists are stricter than the league's wording.

Allegiant Stadium

Allegiant Stadium's first-time guest page, per its site on October 1, 2026, matches the league on clear-bag size (12 x 6 x 12 inches) and permits a wallet or clutch of 4.5 x 6.5 x 2 inches. Then its banned-items list goes further: no backpacks, cinch bags or fanny packs, no diaper or camera bags, no seat cushions, and no purse bigger than that clutch. In practice, that means a clear backpack the NFL would accept can be turned away in Las Vegas, at Raiders games and concerts alike. It runs paid bag check at three spots, card only, open from gates until 60 minutes after the event ends.

MetLife Stadium

The stadium FAQ on the Jets' site, per its site on October 1, 2026, sets the clear-bag limit at 12 x 12 x 6 inches and also accepts a one-gallon clear food storage bag. A clutch roughly the size of your hand, 4.5 x 6.5 inches, can ride inside the clear bag or be carried separately. The stadium turns away coolers, camera bags, purses, cinch bags, fanny packs and backpacks. The same rules apply to Giants games, and its bag check is outside, between the Verizon and HCL Tech gates.

Other stadium notes

Arrowhead Stadium (2025 season): a clear backpack within 12 x 6 x 12 inches is acceptable.
Gillette Stadium (2025 season): instead of a clutch you may bring a wristlet (6.5 x 4.5 inches maximum), and mobile lockers take other bags.
SoFi Stadium (2026): the clear-bag rule covers every event, not only football.
Mercedes-Benz Stadium (2026): fans are advised to bring no bag for the quickest entry.

Baseball parks set their own limits

MLB has no league-wide clear-bag rule like the NFL's. Each club posts its own, and many allow a bigger bag than any football stadium. As listed on team sites in 2026:

Yankee Stadium: you may carry a soft-sided bag of 16 x 16 x 8 inches or less and one smaller soft-sided personal item. No hard-sided bags. Your bag has to drop into the sizing bins without squeezing, nothing can be stored on site, and the club notes that concerts and other non-baseball dates may follow other rules.
Wrigley Field: purses, soft bags, soft coolers, fanny packs and drawstring bags are fine at 16 x 16 x 8 inches or smaller. No backpacks of any kind, clear ones included.
Fenway Park: single-compartment bags up to 12 x 12 x 6 inches. Clear is encouraged; backpacks, duffels and clear backpacks are refused.
Dodger Stadium: the clear-bag limit is 12 x 12 x 6 inches, a non-clear clutch can measure about 5 x 8 x 2 inches, and paid lockers sit in Lots H and N.
loanDepot park: the clear-bag limit is a roomier 16 x 16 x 8 inches; small clutches and medical or baby bags are also allowed.

The common thread is the backpack. A large tote may sail through at a ballpark that still refuses the smallest backpack.

Arenas, from strictest to most relaxed

Indoor arenas run the widest range, and several refuse the clear bag that works at every NFL stadium. Listed roughly from tightest to loosest:

Ball Arena (Denver), 2026: no general bags at all. Only medical and diaper bags are admitted, at 14 x 14 x 6 inches or less, through designated doors.
TD Garden (Boston), per its site on October 1, 2026: the cap is 6 x 4 x 1.5 inches for any bag, clear or not. Breast pump, diaper and medical bags are exempt.
Crypto.com Arena (Los Angeles), per its site on October 1, 2026: the only personal bag allowed is a clutch or wallet under 5 x 9 x 1 inches. Totes, purses, backpacks, camera bags, fanny packs and even clear bags are refused; parents and guests with medical needs may bring a bag under 14 x 14 x 6 inches, which is X-rayed.
Sphere (Las Vegas), 2026: a purse, clutch or fanny pack can measure roughly 6 x 6 x 2 inches.
T-Mobile Arena (Las Vegas), per its site on October 1, 2026: personal bags may not exceed 9 x 5 x 2 inches; crossbody, clear and fanny-pack styles are fine inside that limit.
Barclays Center (Brooklyn), fall 2026: 10 x 6 x 2 inches is the maximum, and backpacks are banned regardless of size.
State Farm Arena (Atlanta) and Chase Center (San Francisco): bags up to 14 x 14 x 6 inches.
Madison Square Garden and Radio City Music Hall, fall 2026: bags need not be clear, and the size ceiling is a generous 22 x 14 x 9 inches.

The gap between the top and bottom of that list is too wide to guess. For why indoor venues tend to be stricter, see the arena vs. stadium guide.

Medical gear, diaper bags and other exemptions

Almost every venue makes room for medical equipment, and many extend the exception to diaper bags. The terms differ:

NFL stadiums let medically necessary items in once they are inspected, frequently at a single gate. MetLife routes them through a specified entrance.
Arenas tend to put a size limit even on exempt bags (Crypto.com Arena and Ball Arena both use 14 x 14 x 6 inches) and screen them by X-ray.
Ball Arena sends medical and diaper bags to specific doors for screening.
Allegiant Stadium prohibits diaper bags though inspected medical items are still allowed, so parents should plan around that.

Locate that entrance on the stadium or arena map ahead of time. Standing in the general line with an exempt bag usually ends with being sent to another gate.

Turned away at security: your options

Paid bag check: You will find one at TD Garden, T-Mobile Arena, SoFi Stadium, MetLife Stadium and Allegiant Stadium, and Crypto.com Arena directs guests to nearby lockers. Expect a per-bag fee and card-only payment.
No storage: Yankee Stadium says it has none, and Madison Square Garden offers neither a bag check nor a coat check, so a bag that fails security there has to go back where it came from.
No re-entry: Leaving and coming back is not allowed at T-Mobile Arena and plenty of other venues, so whatever you check stays out of reach until the end.

Even when a bag check exists, the detour can cost you kickoff or the opening act. A single inexpensive clear bag sized within 12 x 6 x 12 inches, plus a small clutch, covers every NFL stadium; for a strict arena, carry nothing bigger than a phone wallet.

Before you leave the house

Read the venue page that week. Last season's rule may not be this season's, and a concert can differ from a game.
Measure the bag against the stated dimensions.
Leave the backpack unless the venue names yours as allowed.
Use pockets for the phone, ID, payment card and keys.
Have your ticket loaded before you reach the gate; the mobile ticket transfer guide explains how.

The event day guide covers the rest of the day, from arrival to the ride home.

Frequently asked questions

How big can a clear bag be at an NFL game?

The NFL caps it at 12 x 6 x 12 inches in clear plastic, vinyl or PVC, per its policy page on October 1, 2026. You can swap in a one-gallon clear freezer bag, and add a clutch no bigger than 4.5 x 6.5 inches.

Can I bring a clear backpack to Allegiant Stadium?

Plan on no. As listed October 1, 2026, Allegiant Stadium's prohibited list bans backpacks, cinch bags and fanny packs, even though its clear-bag size limit matches the NFL's.

Does MetLife Stadium have a bag check?

Yes. When checked on October 1, 2026, the bag check sat outside the building between the Verizon and HCL Tech gates. Giants and Jets games follow the same bag rules.

Why did an arena refuse my clear stadium bag?

Arena limits are often far smaller than stadium limits. Nothing over 6 x 4 x 1.5 inches gets into TD Garden, and Crypto.com Arena prohibits clear bags entirely, allowing only small clutches and wallets.

Can I bring a diaper bag to a stadium?

Often, but not everywhere. Plenty of arenas accept a diaper bag of 14 x 14 x 6 inches or less once it is screened, while Allegiant Stadium lists diaper bags as prohibited. Check the venue page before you go.

Are bag rules the same at a concert in a stadium?

Frequently, but not always. SoFi Stadium applies its clear-bag rule to all events, while Yankee Stadium notes that different rules may apply at non-baseball events.
