Tent Size Guide: Find the Right Fit for Your Event

The right tent size depends on your guest count and what you plan to place inside the tent. As a starting point, a 20×20 tent accommodates up to 40 guests, a 20×30 up to 60 guests, a 20×40 up to 80 guests, and a 20×60 up to 120 guests with standard seated layouts.

Buffet tables, a bar, DJ booth, dance floor, gift table, or photo booth will reduce the space available for guest seating. When several extras are included, choosing the next tent size up usually creates a more comfortable layout.

When your guest count falls between two sizes, the larger tent is usually the better choice. Extra space makes it easier to arrange tables, create comfortable walkways, and accommodate food service or entertainment without making the tent feel crowded.

For example, an event with 55 guests may technically fit beneath a 20×30 tent, but a 20×40 may be more comfortable if you also need a buffet, DJ, bar, or gift table.

Not by default — our tent prices cover 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.

Good question, and we like to be upfront about this: our 20×40 is built by joining two of our 20×20 high peak tents together, and our 20×60 joins three. This gives you a large, continuous covered space, with two or three peaks along the roofline rather than one. It's a great way to cover a bigger event while keeping the same high-peak style you'll see across all our tent sizes.

The listed tent prices include delivery and professional setup by the Harbor City Event Rentals team. They also include the tent structure and professional removal after the event.

Tables, chairs, linens, lighting, sidewalls, fans, heaters, and other event accessories are not included unless they are specifically added to your rental order.

There's no separate delivery fee to worry about.

Just reach out and let us know your guest count and event details — we're happy to talk through custom options and help you find the right fit, even if it's not one of our standard four sizes.

Plan for a bit more space than the tent's footprint itself, since we need extra room on all sides for stakes or weighted anchors. As a general rule, add about 5 feet of clearance around each side of the tent. If you're not sure your space works, send us your measurements and we'll help you confirm before booking.

A larger tent may be available, but changes depend on inventory and availability for your event date. Contact us as soon as your guest count changes so we can review the layout and determine whether your current tent will still work.

Waiting until the final week may limit the available options, especially during busy event seasons.

No. Guest count is the starting point, but your event layout, table style, entertainment, food service, and available property space also affect the size you need.

Two events with the same number of guests may require different tents. A simple seated gathering needs less room than an event that includes a dance floor, buffet, DJ booth, bar, or photo booth.

Every add-on uses space that would otherwise be available for tables, chairs, and walkways. As a general planning guide, allow approximately 8–10 feet for buffet tables, 6–8 feet for a bar, 10×10 feet for a DJ booth, and 256 square feet for a 16×16 dance floor.

These are starting estimates rather than fixed rules. The final space needed will depend on the exact equipment, serving arrangement, and guest flow

In most cases, yes. A dance floor takes up a significant amount of usable tent space and should not be added without adjusting the seating layout.

For example, a 16×16 dance floor requires 256 square feet before allowing space for a DJ, tables, chairs, or walking aisles. Choosing the next tent size up can help prevent the event from feeling crowded

Sidewalls are optional, but they can provide additional protection from wind, light rain, and cooler temperatures. They may be especially helpful for spring and fall events or when the forecast is uncertain.

Because sidewalls can also reduce airflow, your event date, temperature, and comfort needs should all be considered before adding them.

Tent fans can improve air movement during warm-weather events, especially when the tent is crowded or sidewalls are being used. Open sides also allow more natural ventilation when weather conditions permit.

For summer events in the Baltimore area, it is helpful to consider the time of day, shade, guest count, and expected temperature when planning comfort options.

Permit requirements depend on the tent size, event location, property type, and rules of the local jurisdiction or venue. Public parks, schools, commercial properties, and larger events may have different requirements from private residential events.

Customers should confirm the rules with their venue, property manager, park office, or local permitting authority as early as possible.

Reserve your tent as early as possible once your event date and approximate guest count are known. Spring and summer weekends, graduation season, holiday weekends, and popular Saturdays can book quickly.

Early booking also gives you more time to confirm measurements, choose tables and chairs, and plan for weather-related accessories.

Tent installation depends on the surface and the anchoring method required for that location. Grass is often the most straightforward surface for properly anchored event tents, while concrete, asphalt, gravel, patios, and other hard surfaces may require additional evaluation.

Before booking, let us know what surface you have and send photos of the setup area so we can determine whether the tent can be installed safely.

A tent should be installed on a reasonably level and accessible surface. Minor variations may be manageable, but steep slopes, uneven ground, drainage areas, tree roots, or major elevation changes can affect installation and the comfort of tables and chairs.

Photos and measurements are helpful, but some locations may require an in-person site assessment before the setup can be confirmed.
