You should choose a briefcase on a small scale if you only need to carry a small amount of stuff to your workplace (like 90% of us). It is also important to choose a large-sized briefcase if you have large files, paperwork, a laptop, and other large items in your workplace. Having less luggage and choosing a more oversized briefcase for yourself won't be appropriate if you have less luggage. It is sufficient to have a small bag if you have little luggage.
