Windows Explorer does not have this capability. It can only be done with third party software. This is by design.
Determining the disk space consumed by a folder requires recursively going through each subfolder (potentially many thousands) and adding up the numbers. Doing that on a slow drive, or even worse on a busy server over a slow network link, and you have a serious problem. Most computer users will not understand the implications but Microsoft and corporate IT managers do.
Edit: And the numbers thus displayed are at best only an approximation anyway.
