Footing Width and Depth - Do Both Right to Avoid #FAILURE
Footing width and depth are very important. A footing spreads out the weight of the entire building onto the soil. It works just like the foot on your leg.
How Wide Should a House Footing Be?
A house footing should be no less than 12 inches wide. Twenty inches would be a better width. It's important to realize that the little bit of concrete will be a wise investment as you only get one chance to install the footing.

What is the Best Depth for a Footing?
Footing depth can be confused with the thickness of a footing. Eight inches is the minimum thickness for a footing. Ten inches is better and twelve inches is highly desirable.
The depth of the footing in the ground depends on:
- the local frost depth
- how deep you need to go to be in solid strong soil
What Type of Steel Should be in the Footing?
You should put two continuous steel rods in the footing. The diameter should be no less than 1/2 inch. When you get to the end of one rod, overlap the next rod onto the first one at least 16 inches. Use baling wire to tie the two pieces of steel together.
