Ever since engineered framing lumber became common. Traditionally in American construction 16" on-center is common for a lot of framing though roof trusses are often set at 24" in my area. The newer engineered materials like I joists are stronger than standard lumber and have a wide top and bottom so some contractors set them at 19.2" centers because they can use fewer joists which is cheaper for the customer.

What is 24 inches on center?
"24 inches on center" refers to the spacing of structural elements, such as studs, joists, or rafters, in construction. It means that the center of one structural member is located 24 inches from the center of the next member. This spacing is commonly used for framing walls and ceilings, providing adequate support while allowing for efficient use of materials and insulation.

How much weight can A DECK SUPPORT?
It depends on how the deckis "engineered". Some could be built that are barely able to support their own weight. Others could be built strong enough to park your car on them. It depends on the type and dimension of wood used for the joists, the spacing between joists and the length of the span.

What are the best uses for 2x8 lumber in construction projects?

What size joists should be used for a deck?

Why was there not a standard gauge in the 1800s?
Up until 1846 every railway used there own track spacing, many were close to the 8 foot 6 inch size. In 1846 two important railways with 8 foot and a bit spacing decided on the 8 foot 6 and 1/2 inch standard gauge. Since then about 60% of world wide railways use this spacing.
