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.

Common table sizes
| Table | Seats |
|---|---|
| 48 in round | 6 |

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.
