> The how many tables calculator works out how many people fit at a rectangular or round table and how many tables you need for your guests, for weddings, parties and events.

## Inputs

- Table shape
- Length (or diameter) (in, cm, ft, m)
- Space per guest (in, cm, ft, m)
- Seat guests at the ends
- Number of guests

## Results

- Seats per table
- Tables needed
- Empty seats

## Formula

```
Rectangular: seats = 2 × floor(length ÷ space per person) (+ 2 at the ends)
Round: seats = floor(π × diameter ÷ space per person)
Tables = ceil(guests ÷ seats)
```

## Explanation

Each guest needs about 24 in (60 cm) of table edge to eat comfortably, a little more at round tables and for formal dinners. Standard round tables are 60 in (seats 8) and 72 in (seats 10); a 6 ft rectangular table seats 6–8.

### Tips

- Use the figures from your own bills and product labels – prices and appliance ratings vary widely.
- Look at yearly totals: small daily costs add up and make it easier to compare options.
- Round quantities up to whole packs, rolls or bulbs when you shop.
- Re-check the numbers when prices change; most results scale directly with the unit price.

### Common mistakes to avoid

- Confusing watts (power) with watt-hours or kilowatt-hours (energy).
- Comparing prices without bringing them to the same unit first.
- Ignoring one-off costs such as installation, delivery or replacement parts.
