Is it a problem if my form takes up twice as much space in web form than it does in the desktop application?

I am trying to migrate some forms from a desktop implementation to a web implementation, which should still primarily be used by desktop users.

Currently, we have a generic out-of-the-box theme (the default Bootstrap theme) which renders the same forms twice as big as they were in the desktop application. I'm wondering if all of this extra spacing is a problem that needs to be fixed.

Should I try to fit this form on one page like it was in the desktop application, or is it fine that now it requires scrolling?
