Frequently Asked Questions

How many tables do I need for my event?

Divide your total guest count by the number of seats per table, then round up to the nearest whole number. For example, 150 guests at 8 seats per table requires 19 tables. Adding a 5–10% buffer is recommended to accommodate last-minute additions.

How much floor space does each table require?

A standard 5 ft round table needs roughly 78 sq ft of floor space when you include a 4 ft aisle buffer on all sides. Rectangular and banquet tables vary based on their length. This calculator estimates the total floor area based on your table dimensions and aisle spacing.

What is the recommended aisle space between tables?

Most event planners recommend a minimum of 4 feet between tables to allow guests and staff to move comfortably. For high-traffic venues like restaurants, 3 ft may be acceptable, while banquets and weddings typically use 4–6 ft for a relaxed feel.

What table shape is best for a wedding reception?

Round tables are the most popular choice for weddings because they encourage conversation among all guests. Rectangular and banquet tables work well for more formal or family-style dining and can seat more guests per linear foot of table.

Should I include a head table in my seating plan?

A head table is typically reserved for the wedding party, speakers, or VIP guests. It is usually positioned prominently at the front of the room and should be planned separately from your main guest tables. This calculator lets you toggle a head table on or off when estimating space.

How do I check if my seating plan fits in my room?

Enter your room's length and width in the Room Settings section. The calculator will estimate the total floor area your tables require — including aisle space — and compare it to your available room area, showing whether your layout fits.

What is seating efficiency and why does it matter?

Seating efficiency measures what percentage of your room's floor area is actually being used by your table layout. A very high efficiency (above 85%) can feel cramped, while 50–70% is generally considered comfortable for most events. This metric helps you find the right balance between capacity and comfort.

How many seats should I add as a buffer?

A 5–10% buffer is standard for most events to accommodate unexpected guests or last-minute RSVPs. For example, if you expect 150 guests, a 10% buffer adds 15 extra seats, requiring 2 additional tables.
