- No matter if you selected wood fencing materials or vinyl fence materials.
**Calculating how much material you'll need is crucial.** - Once you've made the estimations, we recommend buying about
**10% more fencing materials than calculated**to correct mistakes or for future maintenance.

## How to use this fence material calculator (and the equations behind it)

### Number of posts and sections

To obtain these quantities, **input** the **length** your fence will have and the **space between the posts** (typically 6-8 feet or 2-3 meters).

The tool will use the following formulas:

- If you obtain a decimal in the $\mathrm{\#\ of\ posts}$ formula (as usual),
**round it up**to the nearest integer. - $\text{Fence length}$ and $\mathrm{\#\ of\ posts}$ must use the same units. Our length converter can help.

### Height of the posts

To obtain this quantity, you only need to **input the height of the fences**. As at least 1/3 of the post must be buried in the ground, the formula is as follows:

### Number of rails needed

To know the number of rails, **input the rails per section**. Additionally, the **number of sections** must also be calculated.

### Number of pickets needed

For the number of pickets, **input the fence length, the picket width, and the picket spacing.**

This is the equation behind:

- Fence length, picket width, and spacing must have the same units. Our distance converter calculator can help.
- Like with the $\mathrm{\#\ of\ posts}$ formula,
**round up**the $\mathrm{\#\ of\ pickets}$ to the nearest integer.

### Concrete for post footing

The geometry determines how much concrete we'll need to secure the posts. Therefore, you'll need to **input the shape and dimensions of the post to obtain the concrete volume.** Look at the formulas in the post hole concrete calculator.

### How many pickets do I need for a 100 feet fence?

To know how many pickets you need for a 100 feet fence, consider the picket width and spacing:

- If you use pickets of
**5½" width**with a 2½" spacing, you need**150 pickets**; or - If you use pickets of
**3½” width**with a 2½” spacing, you need**200 pickets**. - For other widths or spacings, use our fence material calculator.

### What's the difference between a fence and a gate?

The difference between a fence and a gate is simple:

- A
**fence**is a structure enclosing an area. Its purpose can be privacy, protection, decoration, or noise isolation. - A
**door**is used to access or exit an enclosed area, such as one enclosed by a fence.
