Effective clear widths calculator

.
The actual door leaf width required to ensure the correct 'Effective Clear Width' as identified in Table 2 and Diagram 9 of Approved Document M 2004 and Figure 14 and table 2 of BS8300 will depend on the combination of several variables for reference:
- Door thickness
- Frame stop size
- Hinge throw (based on the pivot point of the door)
- Face fixed items on the closing face (E.g. Lever handle, pull handle, weatherboard, etc)
