20x20 Marquee High Peak Tent Rental
How many guests can comfortably fit under a 20×20 tent?
A 20×20 high peak tent covers 400 square feet, and capacity depends on your layout. Seated dinner with round tables: 32–40 guests (four to five 60-inch round tables at 8 guests each). Rectangular banquet tables: up to 48 guests. Cocktail-style, standing: 45–60 guests. Theater-style rows with no tables: up to 60–80 guests. For a comfortable seated event, plan on 30–40 guests — which is why our 20×20 High Peak Tent package is built for parties up to 40.

Create a Beautiful Space for Your Celebration
Our 20×20 High Peak Tent is one of the most requested rentals for outdoor events throughout Baltimore, Towson, Pikesville, Owings Mills, Randallstown, Catonsville, Columbia, Ellicott City, White Marsh, Parkville, and the surrounding Maryland communities. With 400 square feet of covered space and a dramatic center peak, it strikes the balance most hosts are looking for: enough presence to serve as a real focal point, without overwhelming a backyard or smaller venue.
We regularly set this tent up for weddings, graduation parties, baby showers, birthday celebrations, family reunions, retirement parties, engagement parties, and corporate gatherings. Comfortably seating up to 40 guests, it works well across a range of layouts — the open peak design keeps airflow and sightlines clean, which matters more than people expect once tables, a buffet line, or a small dance floor come into play.
Layout comes down to how you're using the space. Four to five 60-inch round tables typically seat 32 to 40 guests and suit a seated dinner or reception well; rectangular banquet tables seat slightly more in the same footprint and tend to work better for casual, family-style events. If you're planning something with a mix of dining and mingling — a cocktail hour before a reception, for example — we can help you figure out the split before your date is booked.

These ranges vary by layout. Dinner-only seating generally falls toward the lower end, while cocktail-style or ceremony layouts may reach the higher end. Buffets, bars, dance floors, stages, and additional circulation space will reduce the available guest capacity.
Event Planning Tip
Reserve early during peak season (May–October). Measure your event space, plan for food service, and don't forget lighting for evening celebrations.

Have questions about our 20×20 tent rental? Find answers about pricing, guest capacity, setup space, weather policies, sidewalls, and booking for your next event throughout Baltimore and surrounding Maryland communities.
-
Our 20×20 High Peak Tent starts at $550, which includes delivery, setup, and takedown within our service area. Final pricing may vary based on your event date and any add-ons like tables, chairs, or lighting.
-
It depends on the table type. With 60-inch round tables, you can fit four to five tables, seating 32–40 guests total (8 guests per table). With 6-foot rectangular banquet tables, you can fit up to six tables, seating up to 48 guests. Round tables tend to work better for weddings and formal seated dinners, while rectangular tables are more space-efficient for casual gatherings like graduation parties or family reunions.
-
The tent footprint is 20×20 feet, but plan for a 30×30 foot area on grass — that extra 5 feet on each side is needed for stakes and guy lines. On hard surfaces like a driveway or patio, stakes aren't an option, so we anchor with water barrels or weighted bases instead, which also need some clearance.
-
Yes. On concrete, asphalt, or other hard surfaces where stakes can't be driven into the ground, we anchor the tent using water barrels or weighted bases instead. Let us know your surface type when booking so we bring the right equipment for a secure setup.
-
Our high peak tents are designed to hold up well in typical rain once properly anchored, so most events can proceed as planned. For full details on our weather policy, see our Rental Terms page.
-
Sidewalls are available for the 20×20 tent as an additional rental, not included in the base package. They're a popular add-on for extra wind protection, privacy, or a more finished look — let us know when booking if you'd like to include them.
-
Not by default — our tent price covers delivery and professional setup of the tent itself. This way, you're only paying for exactly what you need. If you'd like tables, chairs, or linens too, just add them separately from our full rental catalog, and we'll deliver and set up everything together.
-
We recommend booking as early as possible, especially during peak season from spring through fall, when weekend dates can book up weeks or months in advance. You can check real-time availability and reserve your date online with a 30% deposit.
-
Full details on cancellations, rescheduling, and deposits are outlined in our Rental Terms page. We recommend reviewing it before booking so there are no surprises.
-
Permit requirements vary by jurisdiction and typically depend on tent size, event type, and whether the setup is on public or private property. A 20×20 tent generally falls under the size that most commonly avoids permit requirements for residential backyard events, but we recommend checking with your local permitting office to confirm what applies to your specific location and event.
-
Our 20×20 High Peak Tent has an 8-foot eave height, with the center peak reaching 16'9" at its highest point. That extra headroom is one of the advantages of the high-peak design — it gives you plenty of clearance for string lights, draping, or a chandelier without feeling closed in.
-
Yes, we offer flexible rental timing. We rent by the day, and in many cases can set up the tent the day before your event and take it down the same night or the following day, depending on how late your event runs — just let us know your schedule when you book.
-
Yes. Harbor City Event Rentals carries liability insurance, and we're happy to provide a Certificate of Insurance upon request — useful if your venue requires proof of coverage before allowing a tent on-site.
-
Before setup, we ask that the area be cleared of furniture, debris, and other obstacles so our crew can work safely and efficiently. It also helps to flag any underground utility or electrical lines in the setup area ahead of time — if staking isn't possible because of buried lines, we'll switch to weighted anchoring instead, so there's no delay on setup day.
-
Yes — decorations, lighting, and draping can be hung from the tent frame. Let us know what you're planning so we can make sure everything is set up to support it safely.
-
Yes, we ask that someone be present for delivery and pickup so we can walk through the setup together, confirm the placement matches what you had in mind, and make sure everything meets your expectations before we leave.
-
Yes — our tents are waterproof and flame-retardant. The top is a heavy-duty 16 oz. PVC-coated polyester vinyl, also UV-resistant and mildew-proof, supported by a commercial-grade aluminum frame built for repeated outdoor use. That means one less thing to worry about if the weather turns during your event.
