Key factors for choosing a framework depending on project size [closed]

Please don’t get the question wrong. This is not A vs B question.

I know that any programming language can bring a project to life.

But many people when the compares frameworks they say this is suitable for medium and large size project. First what makes a web app project medium or large size ?

The size of team working behind it or Is it the code it self or deployment on multi servers or both ?

What make such framework dedicated objectively more than other for this kind of development?

The isolation/decoupling of modules/components is a key factor?

There’s any pattern to follow to make decision before starting?

Thank you.
