Backyard Tent for 50 Guests: Size, Layout and Checklist

Fifty guests is the sweet spot for a backyard party: big enough for a real event, small enough for a regular yard. It is also where hosts underestimate the yard. A 20 x 30 tent is only 600 square feet, but it needs a clear area close to 1,200 once you add working room. This guide walks through the choices.

Pick the size

Details on the math are in what size tent do I need.

Measure your yard first

Measure the flat area, not the whole lot. Subtract steps, trees, planters, utility boxes, the AC unit, grills and slopes. Then compare to the tent size plus working room. A 20 x 30 tent is 600 square feet, and with working room you need an open area of around 30 x 40 feet as a rule of thumb. Ask the tent company what footprint they require. See how much space around a tent. Slopes can be fixed with a floor: see tent flooring and subfloors.

The rental list for 50

• Tent: 20 x 30, with or without sidewalls.
• Tables: six 60-inch rounds seat 8 each (48 guests), or five 72-inch rounds seat 10. Add a buffet or bar table, a gift table and a cake table.
• Chairs: 50 guests plus 3 spares. Garden folding chairs sit well on grass, and cross-back chairs suit a rustic yard. See how many chairs you need.
• Linens: floor-length cloths for rounds; see the tablecloth size chart.
• Lighting and power: see tent lighting ideas.
• Flooring: only if the lawn is uneven or wet.
• Restrooms: a house bathroom may do; add a portable unit if you want guests out of the house.

Before you book

Timeline

A backyard tent typically goes up one to two days before the event and comes down the day after. See tent rental setup timeline. Book as early as you can for summer weekends in the Chicago area. Our guide on when to book applies to tents too.

Power and food

Most backyards have limited outdoor outlets. Count lights, music, a coffee station and warmers, and ask your caterer what power they need. Extra circuits might be needed. Keep grills and fryers away from the tent; codes commonly keep open flame and cooking 20 feet away.

Budget the extras, not just the tent

Hosts tend to compare tent quotes and forget the line items around them. Ask each company to price the tent, delivery, installation, takedown, sidewalls, flooring, lighting, heating or fans and permit handling separately, so you can compare like with like. We do not publish tent prices, but we can help you build the full rental list so nothing is missed: tables, chairs, linens, tableware and glassware are as easy to forget as the tent flooring.
