Restaurant booking durations: how much time should you allow?

Start with real service times

Review several representative services rather than relying on one unusually quick or slow table.

Look at the time between guests being seated and leaving. Then consider how long staff need to clear, clean and reset the table.

Separate quieter evenings from busy services if the pace differs. A duration that works when the restaurant is half full may be unrealistic on Saturday night.

Consider different party sizes

Larger groups may need more time to settle, choose dishes and complete the meal.

That does not mean every large group stays longer than every couple. It means party size is a useful factor when setting realistic defaults.

For illustration, a restaurant might test two hours for smaller parties and two and a half hours for larger groups. Those are examples to evaluate, not universal recommendations.

Table Harmony lets you set booking durations according to party size.

Understand what the duration controls

A booking duration helps the system estimate when a table will become available again.

For example, a reservation starting at 19:00 with a two-hour duration is expected to finish at 21:00.

That expectation does not guarantee the guests will leave at exactly that time. Staff still need to manage the service and any agreed time limit.

If you need preparation time between sittings, check how your system accounts for it. Make sure the next available booking reflects both dining and turnaround time.

Decide whether guests have a table time limit

An internal planning duration and a communicated dining limit are different things.

If a guest must return the table by a particular time, explain that before they book. Include the information in the confirmation where appropriate and remind them politely when they arrive.

For example: “Your table is available from 19:00 until 21:00.”

Avoid introducing a limit only when guests are already seated.

Check overlapping reservations

Before offering a second sitting, consider the effect of a late arrival or a slower meal.

If several tables are expected to turn at 21:00, accepting all their replacements at exactly 21:00 may put pressure on both seating and the kitchen.

Use realistic durations alongside arrival limits. Our guide to staggering restaurant reservations explains how to manage the flow of new guests.

Review exceptions personally

A celebration, tasting menu or group with agreed arrangements may need more time than the default.

Check the duration when entering or editing the reservation. Extending it can affect later availability, so review subsequent bookings before promising extra time.

Staff should understand when an exception needs a manager’s decision.

Handle late arrivals consistently

Decide how you respond when guests arrive late, especially if another party is booked afterwards.

Your response may depend on whether the table is needed again and whether you can still provide the meal comfortably.

Explain the available options clearly. Avoid promising a full dining period if that would conflict with a later confirmed reservation.

Adjust based on what happens

After introducing booking durations, review the results with your team.

Are guests regularly feeling rushed? Are tables usually ready well before the next reservation? Are delays concentrated around certain group sizes or services?

Change the settings when the evidence supports it. The aim is a workable schedule that respects both the guest experience and the restaurant’s capacity.

Setting durations in Table Harmony

Table Harmony supports booking durations by party size alongside table availability, combinations and per-slot guest limits.

Together, these settings help online reservations reflect the way your restaurant operates.
