## What is the standard length between fence posts?

Most fence posts can be spaced 8 to 12 feet apart. While this is a general criteria, it doesn’t cover all scenarios. For instance, high tensile fence can have larger spacing, requiring line posts every 15 to 20 feet for field fence styles, and as much as 20-30 feet for high tensile barbed and smooth wire.

**How do you calculate fence post length?**

Number of posts = (fence length / post spacing) + 1 (round the result up) Number of sections = number of posts – 1. Post length = fence height * 1.5.

### How long should a corner post be?

8 feet long

Corner posts generally need to be 6-8 inches in diameter, 8 feet long and set a minimum of 3-1/2 feet deep. To determine the proper length, add together the depth of setting, which should be no less than 3-1/2 feet in the ground, plus the height of the top wire above the ground, plus 6” extra.

**How long should post be for 4 foot fence?**

six feet long

When figuring out what size T-post to use for a four-foot fence, remember that you will drive the posts about two feet into the ground. This means you need posts that are at least 24 inches longer than how tall you want your fence. For a four-foot fence, you should use T-posts that are at least six feet long.

#### How do you calculate post length?

An example is if you chose a concrete post for a flat garden, for a 6ft fence your post would have to be planted at the depth of a 1/3 of your fence panel. So for this fence, 6 ÷ 3 = 2 so the post would have to be planted a 2ft deep so therefore you would need an 8ft fence post.

**What size Post do you use for a 6 foot fence?**

Post lengths for fences start at 8 or 10 feet for a 6-foot-tall fence. They are commonly four-by-fours, which measure approximately 3 1/2 by 3 1/2 inches, or six-by-sixes, at around 5 1/2 by 5 1/2 inches.

## What size t-post do I need?

Firstly, let’s establish one simple rule: your t-posts should be about two feet longer than the height of your fence. This is why t-posts are typically sold at lengths between 5 and 10 feet.
