How Many Tables Calculator
Calculate table seating capacity and determine how many tables you need for events, weddings, and parties
Calculate Table Requirements
Recommended: 60cm for rectangular tables
Length of the table (longer side)
Width should be at least 80cm for comfort
Results
Formula: Seats = (Length ÷ 60cm) × 2
Example: 8-Seater Dining Table
Rectangular Table Option
For 8 people with 60cm per person:
Length needed = (8 ÷ 2) × 60cm = 240cm
Alternative with head seats:
Length needed = (6 ÷ 2) × 60cm = 180cm + 2 head seats
Round Table Option
For 8 people with 70cm per person:
Required radius = (8 × 70cm) ÷ (2π) ≈ 89cm
Table diameter ≈ 178cm
Wedding Example
200 guests with round tables (radius 150cm):
Seats per table = (2π × 150cm) ÷ 70cm ≈ 13 people
Tables needed = 200 ÷ 13 ≈ 16 tables

Consider table decorations in space calculations
Understanding Table Seating Calculations
Rectangular Table Formula
Seats = (Length ÷ Space per Person) × 2
Plus optional head seats (+2)
- •People sit along both long sides of the table
- •60cm per person is comfortable spacing
- •Table width should be at least 80cm
- •Head seats optional for smaller groups
Round Table Formula
Seats = (2π × Radius) ÷ Space per Person
Circumference divided by space needed
- •People sit around the entire circumference
- •70cm per person recommended for comfort
- •No head of table - everyone equal
- •Better for conversation and interaction
Event Planning Considerations
Space Planning
- • 90-120cm between tables
- • Access to exits and restrooms
- • Space for serving staff
- • Dance floor or presentation area
Guest Comfort
- • Adequate elbow room
- • Easy chair access
- • Good sight lines
- • Appropriate table height
Practical Tips
- • Plan for 10% extra capacity
- • Consider children's seating
- • Account for centerpieces
