Footings will differ based upon the type of project. Most footings, if building a deck for example, should be about six feet apart.
Foundation footings on black cotton soil should be designed to accommodate the swelling and shrinkage properties of the soil. It is important to have a wider and deeper footing to distribute the load over a larger area. Proper drainage and moisture control measures should also be implemented to prevent water-induced swelling and structural damage.
To ensure a stable and secure foundation for your deck, it is important to follow these best practices for installing deck post footings: Dig deep holes for the footings, below the frost line if applicable. Use concrete to fill the holes and set the footings securely in place. Ensure the footings are level and properly aligned with the deck layout. Use metal post anchors or brackets to attach the posts to the footings for added stability. Allow the concrete to cure fully before building the deck on top of the footings.
The recommended depth for deck footings is typically around 36 inches to 48 inches deep. Installing deck footings at this depth helps ensure stability and safety by providing a solid foundation for the deck structure.
A structure need a foundation that supports it. If the structure is built on a soil that has bearing capacity which can withstand the weight of the whole structure, then you can design the foundation on footings alone. But if the soil is WEAK, you need piles to penetrate further the soil to have greater bearing strength.

The best footings for a deck to ensure stability and longevity are typically concrete footings that are deep enough to reach below the frost line and properly spaced to support the weight of the deck evenly. Additionally, using galvanized or stainless steel hardware to attach the deck to the footings can help prevent corrosion and increase the deck's lifespan.
