You’re standing on 7th Avenue. The lights are blinding, the crowd is a literal sea of humanity, and you can hear the muffled roar of the crowd inside "The World’s Most Famous Arena." You reach for your ticket on your phone, feeling that pre-show adrenaline. Then, you see the security guard’s face. He’s pointing at your backpack.
It’s too big.

Honestly, it’s a nightmare scenario that happens to hundreds of people every single week. Whether you're here for a Knicks buzzer-beater, a Rangers power play, or a sold-out concert, the madison square garden bag policy is the one thing that can absolutely tank your night before it even starts. Most people think they can just "squeeze by" or that "it's just a normal backpack."
Spoiler: Security doesn't care.
The Size Rule is Everything
Basically, the Garden operates on a "travel light" philosophy. They don't have a specific "clear bag only" rule like many NFL stadiums or newer arenas, which is a relief if you don't want the world seeing your backup snacks and personal items. But there is a hard limit on dimensions.
If your bag is larger than 22” x 14” x 9”, you aren't getting in. Period.
Think about that for a second. That is roughly the size of a standard carry-on suitcase. While that sounds generous, here is the kicker: it has to fit comfortably under your seat. MSG is a historic building. The seats are tight. If your bag is a bulky hiking pack that technically hits the measurements but won't squish under the plastic chair in Section 106, you’re going to have a bad time.
What Most People Miss About Backpacks
Let’s talk about the "Backpack Trap."
While the official rules say bags must be under the 22x14x9 limit, security personnel at MSG are notoriously picky about traditional backpacks. Even if it’s a small school bag, it’s going to trigger a much more intensive search. Many frequent flyers at the Garden swear by bringing a crossbody bag or a small tote instead.
Why? Because the "No Bag" express lines are a godsend.
If you can fit your essentials—wallet, keys, phone, portable charger—into your pockets or a tiny clutch that’s basically a wallet with a strap, you will breeze through security in five minutes. If you bring a bag, even a legal one, you're looking at the X-ray machines and a much longer wait.
The "No Storage" Reality Check
This is the part that trips up tourists every single time.
Madison Square Garden does not provide a bag check. There are no lockers. There is no "hold it at the front desk." If you show up with a suitcase because you just came from Penn Station (which is literally right underneath the arena), the staff will simply tell you that you can't enter. You'll be left scrambling on the sidewalk, trying to find a third-party storage app like Bounce or Radical Storage while the opening act is already on stage.
I've seen it happen. It’s stressful, it's expensive, and it's totally avoidable. If you’re traveling, drop your gear at your hotel or use one of the luggage storage spots at Moynihan Train Hall before you even walk toward the MSG entrance.
What’s Actually Prohibited?
Beyond the size, the list of "no-nos" is pretty standard but strictly enforced:
- Professional Cameras: If the lens is detachable, leave it at home. Point-and-shoots are usually fine unless the artist has a "no photos" rule.
- Laptops and Tablets: Technically allowed if they fit in a legal bag, but honestly? Don't do it. If you're going to a "Device Free" event (like some comedy shows), these will be locked in Yondr pouches anyway.
- Outside Food and Drinks: Not happening. Don't even try to sneak in that bottle of water. You can bring an empty, clear, soft-plastic bottle to fill at the fountains inside, though.
- Signs and Posters: If it's bigger than 20" x 18" or attached to a pole, it's going in the trash.
How to Handle Special Situations
Life happens. Sometimes you need more than just a phone and a wallet.
If you’re a parent, strollers are permitted, but they must be the collapsible kind that fits under your seat. Don't bring the massive jogging stroller you use for trips to the park. For those with medical needs or disabilities, the Garden is actually pretty accommodating. If you have a medical bag that exceeds the size limit, you should contact Guest Relations at (212) 465-6225 ahead of time. Usually, they'll direct you to a specific entrance where security is briefed on medical exceptions.
Actionable Tips for a Stress-Free Entry
Don't let a bag ruin your night. Follow this checklist and you'll be inside buying overpriced (but delicious) chicken tenders in no time:
- Measure your bag twice. Use a tape measure. If it’s even close to 22 inches, pick a smaller bag.
- Go small or go home. If you can fit everything in a 6" x 9" clutch, you'll have the easiest experience.
- Check your event type. Is it a "Device Free" show? If so, leave the tablet and the smartwatch at the hotel. It saves you the hassle of the Yondr pouch line.
- Arrive 45 minutes earlier than you think. Between the Penn Station construction and the security lines, the Garden area is a maze.
- Use the "No Bag" line if possible. Look for the signs. They are significantly faster and much less stressful.
The madison square garden bag policy exists for safety, sure, but also for flow. Thousands of people need to get through those metal detectors in a very short window. By playing by the rules and traveling light, you aren't just making life easier for security—you're making sure you actually see the first song or the opening tip-off.
Keep it small, keep it simple, and enjoy the show.
