Here something that might help you

Here is a page for joist size
They also have app for the phone works great


Works great Mike the app is free

It’s a nice App. I don’t understand why they need access to your WiFi, phone number, and other personal info to use it.

Not sure but most apps do , But you can still use the web page

Nice, Thanks
