**Formulas for Calculating Amounts of Materials Needed**

**In this post I will explain how to calculate Square Footage, Square Yardage, and Cubic Yardage, which will be of assistance when purchasing certain materials.**

**1. **__Square Footage__

__Square Footage__

**Square Footage formula is simply: Footage Length x Footage Width = Square Footage****.**

This **Square Footage **measurement will be needed for a variety of projects, such as: flooring, sod, painting, paver patios, etc. Since many of the individual items needed in order to complete these types of projects are measured in inches, most suppliers will calculate the **Square Footage** coverage for you, in order to make it easier for you to purchase the correct amount of the materials needed.

For instance, most flooring comes in boxes, with the amount of **Square Footage** coverage per box, listed on the outside of the box. Also, most suppliers will be able to tell you, or have posted, the number of pavers needed per **Square Foot**.

However, if you need to make these calculations yourself, and if your initial measurements, such as a single paver for a patio is in inches, you will first need to calculate the **Square Inches** of the paver, and then convert that total to **S****quare Feet**.

First, you need to know that there are **144 Square Inches in a Square Foot.** (**12” x 12” = 144“**).

Next, you need to know the **Total Square Footage** of your proposed patio. **Length x Width = Total Square Feet**.

So, you would make the calculation as follows:

**L x W**of a single paver =**Square Inches**.- Then, convert the
**Square Inches**into**Square Feet**, by**dividing****144**(# of**Square Inches**in a**Square Foot**) by the**Total****Square Inches**of the single paver or patio stone. - Multiply
**L x W**of your proposed patio =**Total****Square Feet**. **Total****Square Feet**for patio**x**the number of pavers per**Square Foot**=**Total**number of pavers needed.

**Example:** If your paver is** 4” x 8”**, and your patio will be **20’ x 30’** calculate as follows:

- Multiply
**4” x 8”**=**32****Square Inches**. **144” divided by 32” = 4.5**pavers per**Square Foot**.- Your
**20’ x 30’ patio = 600****Square Feet**. **600 Total Square Feet x 4.5**pavers needed per**Square Foot****=****2700**pavers needed.

**2.** __Square Yardage__

__Square Yardage__

**Square Yardage formula is simply: Square Footage divided by (9) = Square Yardage.**

Sod usually comes in (**1)** **Square Yard** rolls which measure **6’ Long x 18” Wide**.

To verify that this is indeed (**1)** **Square Yard**:

- You must first convert all of your dimensions to the same unit of measurement.
- Convert your
**18”**Width measurement to**Feet**(**18” divided by 12” in a Foot = 1.5 Feet**). - Then, multiply
**L****x W**in order to get your**Square Footage**(**6’ Long x 1.5’ Wide = 9****Square Feet**). - Then,
**divide**your**Square Footage****by****(9)**to get your**Square Yardage**. **(9) Square Feet divided by 9 = 1****Square Yard.**

To determine how many rolls of sod will be needed to cover a given area, the **f****ormula is simply:**

**Footage Length x Footage Width = ****Square Footage.**

**Square Footage divided by (9) = Square Yardage **(or the number of sod rolls needed).

**Example: **If the area that you need to cover with sod is: **10’ Long x 10’ Wide**:

**Multiply**the**(2)**dimensions to get your**Square Footage**(**10’ x 10’ = 100’ Square Feet**).**Divide**your**Square Footage****by (9)**to get the number of**Square Yards**(sod rolls needed).

(**100 Square Feet divided by (9) = 11.11 or (12) Sod Rolls needed**).

**3. **__Cubic Yardage__

__Cubic Yardage__

**Cubic Yardage is measured in yards rather than feet: 3 Feet = 1 Yard.**

**Cubic Yardage formula is simply: Yardage Length x Yardage Width x Yardage Height (or Depth) = Cubic Yardage.**

**There are (27) Cubic Feet in (1) Cubic Yard (3’ x 3’ x 3’ = 27).**

**Cubic Yardage **is often used to calculate the amount of material needed for certain yard projects, such as: topsoil, gravel, mulch, decorative stone, concrete, etc. You usually make your initial measurements in feet, multiply **L x W x H = Cubic Feet**. Then, **divide** the **Cubic Feet ****by** **(27)**, which is the number of **Cubic Feet **in a **Cubic Yard**.

**Example: **If the area you are going to install a given material measures **130’ **in** Length**, is **2’ Wide**, and the material to be installed needs to be **12” **in** Height**, the steps to make the calculation is as follows:

- You must first convert all three dimensions to the same unit of measurement. So, convert your
**12” Height**measurement to**Feet**(**12” divided by 12” in a Foot = 1 Foot**). - Multiply the three dimensions together to find the number of
**Cubic Feet**.

Multiply the **L x W x H **(**130’ x 2’ x 1’ = 260’**).

- Divide the number of
**Cubic Feet**by the number of**Cubic Feet**in a**Cubic Yard**(27) to find the number of**Cubic Yards**. (**260 divided by 27 = 9.6 Cubic Yards**).

You will need **10** **Cubic Yards **of the material to complete your project.
