Garden Party Planning Guide: Ideas, Marquees & Tips for 2026

The garden party is one of the most popular events Aries Leisure supplies marquees for across Liverpool and the North West, and for good reason. A garden party with a proper setup, covered seating, a decent bar, and a bit of thought put into the layout has the potential to be significantly more enjoyable than an equivalent event at a pub or function room. The space is yours, the atmosphere is yours, and there are no venue rules about when it ends.

Getting it right, though, requires some planning. This guide covers the decisions you need to make before the day to give your 2026 garden party the best possible outcome.

Start With the Guest List and the Space

Before any other decision, you need a realistic picture of your garden’s capacity. Measure the usable outdoor space, taking out any areas with obstructions, slopes, or access routes you need to keep clear. As a starting point:

• For standing-only, allow 1 square metre per person
• For a mix of seated and standing, allow 1.5 square metres per person
• For fully seated with tables and chairs, allow 2 to 2.5 square metres per person

A typical back garden in Liverpool or Merseyside of 60 to 80 square metres of usable space comfortably accommodates 30 to 40 guests for a seated event. If you are planning for more than this, a marquee is the practical solution. It provides the covered, dedicated event space and leaves the remainder of the garden for movement between areas.

When sizing a marquee for your garden, work from the maximum guest count plus the space you need for a bar, a food service area, and if applicable a small dance floor. Most party marquees for garden events run from 3m x 6m (for 20 to 30 guests) up to 6m x 12m (for 60 to 80 guests with a dance floor).

Catering: What Works Outdoors

Garden party catering has its own specific requirements. The challenges of outdoor catering are heat, insects, and the practical difficulty of serving hot food without a professional kitchen within reach.

Formats that work consistently well for outdoor garden parties:

• BBQ and grill stations. The most natural fit for a garden party. A commercial BBQ hire gives you professional-grade cooking capacity without the domestic grill limitations. A catering team running the BBQ frees the host to socialise.
• Buffet with covered serving stations. Keeps food accessible and self-served, avoids the logistics of table service outdoors. Use covered trays or a shaded buffet table to keep food at the right temperature and manage insects.
• Grazing tables and street food stations. Popular for daytime and early evening parties. Boards of cheese, charcuterie, and bread, supplemented by a street food option, work well for an informal register and take minimal coordination on the day.
• Canapés for cocktail-format parties. If the event is primarily a drinks reception with food as a supporting element, canapés passed by staff cover the food requirement without a dedicated seating meal.

Setting Up the Bar

The bar is where most garden parties either work well or become stressful. A host serving drinks from a kitchen or a folding table while trying to attend to 60 guests is not a good outcome for anyone.

For parties above 30 guests, a dedicated bar setup makes the event significantly easier to manage. Options:

• Self-service drinks area. A designated table or bar unit with drinks set out, ice, and glasses. Works for drinks parties with a drinks reception format. Loses structure once the queue builds.
• Mobile bar hire with staff. A professional bar team handles all drinks service throughout the event. You stock the bar, they manage it. The standard for parties above 50 guests.
• Drinks package with a staffed bar. Where the bar team brings the drinks stock and manages all ordering, delivery, and quantities. Less control over the selection, but maximum convenience for the host.

For a garden party of 60 to 80 guests running from midday to 9pm, plan for six to eight drinks per person across the event. Wine, beer, Pimm’s, and soft drinks suit the garden party register well. Cocktails require more specialist preparation and equipment.

Seating: How Much and What Style

Seating for a garden party does not need to be formal. The right approach depends on the format:

• Relaxed mingling party: Seating for around 60 to 70% of guests. The rest stand or drift between areas. Poseur tables and lounge furniture add variety without committing everyone to a table.
• Seated meal with garden party feel: Full seated dining for all guests, trestle or round tables dressed with simple linens. Does not need to feel formal, but requires a full chair count plus serving space.
• Hybrid format: Seated dining area under the marquee, lounge/drinks zone on the lawn or patio. Works well for events with a meal in the early part and a looser drinks and dancing format in the evening.

Table and chair hire for garden parties typically covers folding or banqueting chairs, round or trestle tables, and any poseur tables for the drinks area. Aries Leisure coordinates furniture alongside the marquee hire and delivers everything in a single installation.

Weather Planning: The Honest Approach

British summer weather is not reliable. Every outdoor event needs a contingency.

The clearest solution is a marquee: a properly installed marquee keeps guests dry and comfortable regardless of weather, and the Aries Leisure flooring option protects the lawn surface and keeps heels out of the ground. A marquee for a garden party is not an extravagance for large guest lists; it is the practical answer to a question that will otherwise be answered for you on the day by the forecast.

If a full marquee is not in your plan, consider:

• A party tent hire for a smaller shelter structure in one area of the garden
• A backup indoor space in the house that can absorb guests if the weather turns
• Good outdoor heaters if the evening is expected to drop in temperature

Décor and Atmosphere

Garden parties give you more creative latitude than most event types. The most effective décor approaches are also the simplest: flowers and greenery that match the season, string lights or festoon bulbs for evening, simple table linens in a consistent colour scheme, and centrepieces at a height that does not impede conversation across the table.

For evening garden parties, lighting is the biggest single factor in how the event feels after sunset. Festoon lighting overhead, uplighting washing the marquee interior in your chosen colour, and lanterns or candles on tables all work well without overcomplicating the setup.

The LED dance floor hire is a popular addition for evening events where dancing is part of the plan. A 12ft x 12ft LED floor is enough for 60 to 80 guests and makes a strong visual focal point within the marquee.
