Might have to go to 12” spacing on floor joists. That being said, my shop is 12×24 with 2×10 floor joists spanning 12’ on 16” centers. The floor is strong. I have a 3hp sawstop in the middle with no problem.

Don’t forget floor capacity is more than center line of joists and size. It is also the thickness and density of actual floor on top of joists. Higher live loads usually translates into thicker flooring, using a mix of OSB, plywood, and/or solid wood to better distribute loads using opposing grain directions. Also have to reinforce any large openings in floor differently too.

There is a lot of science to a strong foundation and floor.

I would personally never make a flooring recommendation without all information on what will be inside the building, max number of occupants, and local building code requirements for natural disaster risks for geographical area where building is located.

Again my work shop flooring tip:
Consult a professional to ensure you get floor loading design right for your application.
Better to be safe, than sorry.
