The most common hog wire gauge for a fence is 12.5. However, you can choose from a few gauges based on your needs. While 12.5 is a reliable gauge for penning in large, strong animals, 9 gauge is a better option of you have large animals that are easily spooked, such as horses. For smaller animals, like dogs or pigs, you can use a 16 gauge hog wire.

The average lifespan of a wood fence is 15 to 20 years, but some can last for 40 years or more depending on several factors. The type of wood is crucial; for example, untreated pine may only last 5 to 10 years, while pressure-treated pine can last up to 20 years, and cedar's natural resistance can extend its life to 40 years. Other factors include local weather conditions, with wet and windy climates causing faster deterioration, and the quality of maintenance. Higher-end wood, metal posts, and privacy fence styles also tend to last longer.

The cheapest fence to install is likely to be a wire fence, whether it’s hog wire or chicken wire. Closely following that is something repurposed that would be free to collect, like a DIY pallet fence. Most wire fences are available in large quantities at a low cost, so they’re great for homes with a tight budget.

When considering how much of a gap should be under a fence or gate, a good rule of thumb is to keep gaps between 2 and 5 inches tall. This allows for some ground clearance for the gate but still provides safety for children and pets, who shouldn’t be able to squeeze through a gap of that size.
