# Square Feet to Square Yards Calculator

> This square feet to square yards calculator converts an area in either direction and prices it if your material is sold by the square yard.

**Quick answer:** Divide square feet by 9 to get square yards, because a square yard is 3 ft × 3 ft. A 450 sq ft room is 50 square yards; at $24 per square yard, carpet for it costs $1,200 before waste.

## How to convert square feet to square yards

A square yard is a square that measures 3 feet on each side, so it holds 3 × 3 = 9 square feet. To convert, divide by 9; to go back, multiply by 9.

```
square yards = square feet ÷ 9
square feet = square yards × 9
```

Example: a 450 sq ft room is 450 ÷ 9 = **50 square yards**. At $24 per square yard the material costs **$1,200**. Add 10% waste and you would order 55 square yards, or $1,320.

### Where square yards are used

- Carpet, often priced per square yard.
- Sod, lawn seed and landscape fabric on larger jobs.
- Paving, pavement and some flooring estimates.

Do not divide by 3: that gives a length in yards, not an area. For lengths see the [feet to yards calculator](../feet-to-yards-calculator/). To measure the room first, use the [square footage calculator](../square-footage-calculator/), and for carpet roll planning the [carpet calculator](../carpet-calculator/) or [flooring calculator](../flooring-calculator/).

## Frequently asked questions

### How many square feet are in a square yard?

9. A square yard is 3 ft by 3 ft.

### How do I convert square feet to square yards?

Because area is length times width. Both sides are multiplied by 3, giving 3 × 3 = 9.

### Is carpet sold by the square yard?
