The Sinclair Bag Policy: Everything You Need to Know Before Your Show in Cambridge, MA

The Sinclair Bag Policy

Located in the heart of Harvard Square, The Sinclair is one of Cambridge's premier live music venues, hosting everything from indie rock to hip-hop performances in an intimate 525-capacity space. Before heading to your next show at this beloved venue, it's essential to understand their bag policy to ensure a smooth entry and avoid any delays at the door. Whether you're catching an up-and-coming artist or a nationally touring act, knowing what you can bring will help you focus on what matters most—enjoying the music.

The Sinclair takes security seriously while maintaining a welcoming atmosphere for concertgoers. Their bag policy is designed to keep everyone safe while allowing guests to bring necessary personal items. Understanding these guidelines ahead of time means you can plan accordingly and breeze through security when doors open.

What Bags Are Allowed at The Sinclair?

According to The Sinclair's official policy, bags smaller than 14″x14″x14″ are permitted. This is good news for concertgoers who need to bring essentials like wallets, phones, and small personal items. Here's what you need to know about acceptable bags:

  • Maximum Size: Bags must be smaller than 14 inches x 14 inches x 14 inches
  • Clear Bags Not Required: Unlike many venues, bags do not have to be clear, giving you more flexibility in what you bring
  • Small Purses and Clutches: Standard-sized purses, crossbody bags, and small backpacks that meet the size requirements are welcome
  • Inspection Required: All bags are subject to search for any prohibited items
  • Medical Bags: Medical bags and necessary medical equipment are typically permitted but will be inspected by security

The 14″x14″x14″ size limit is relatively generous compared to many concert venues, allowing you to bring a reasonably sized bag without needing to purchase a special clear bag or leave your belongings at home.

Prohibited Items

To maintain a safe environment for all guests, The Sinclair prohibits several items from being brought into the venue. The venue does not permit markers, spray paint, weapons (including pocket knives), laptops, or tablets. Here's a comprehensive list of what to leave at home:

  • Weapons of any kind: This includes pocket knives, regardless of size
  • Markers and spray paint: To prevent vandalism and property damage
  • Laptops and tablets: Leave your electronics at home or in your car
  • Professional camera equipment: Large cameras and video recording equipment are not allowed
  • Outside food and beverages: The venue has a full-service restaurant and bar for your refreshment needs
  • Large bags and backpacks: Anything exceeding the 14″x14″x14″ size limit will not be permitted
  • Laser pointers: These can be dangerous and disruptive during performances

If you arrive with a prohibited item, you'll be asked to return it to your vehicle or make other arrangements. The venue does not provide storage for prohibited items, so it's best to plan ahead.

Tips for a Smooth Entry

Want to get into The Sinclair quickly and start enjoying your show? Follow these helpful tips to make your arrival as seamless as possible:

  • Measure your bag before leaving home: If you're unsure whether your bag meets the 14″x14″x14″ requirement, measure it to avoid disappointment at the door
  • Bring only essentials: The smaller and lighter your bag, the faster you'll get through security. Consider bringing just your phone, ID, payment method, and keys
  • Arrive early: Doors typically open 30-60 minutes before showtime, and arriving early means shorter security lines
  • Have your ticket ready: Whether it's a mobile ticket or physical ticket, have it easily accessible on your phone or in hand
  • Bring valid ID: You'll need government-issued photo identification if you're 21+ and plan to purchase alcohol, or to verify your age for age-restricted shows
  • Use the coat check: The Sinclair offers a seasonal coat check, which can be helpful if you're carrying bulky winter items
  • Consider going bag-free: If possible, skip the bag entirely and use your pockets for essentials to speed through security even faster
  • Check parking options in advance: Street parking in Harvard Square can be challenging, so plan to use nearby parking garages or take public transportation via the Harvard Square Red Line station
