In this **Post**: **How to Calculate Amount of Material Needed**, I will explain how to calculate **Square Footage**, **Square Yardage**, and **Cubic Yardage**, which will be of assistance when purchasing certain **Materials**, such as: **Gravel, Sod, Mulch, Decorative Stone, etc.**

__Square Footage__

__Square Footage__

**Square Footage Formula: Length x 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.

__Square Yardage__

__Square Yardage__

**Square Yardage Formula: 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 **Formula** is:

**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**).

__Cubic Yardage__

__Cubic Yardage__

**Cubic Yardage Formula: Yardage Length x Yardage Width x Yardage Height (or Depth) = Cubic Yardage.**

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

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** are 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**.
