Understand the active and inactive leaves
One leaf usually serves daily traffic while the second is released when extra width is needed. Confirm which side should be active and how furniture, switches and interior circulation affect the swing.
The inactive leaf needs secure top and bottom engagement. Both leaves should meet evenly at the centre without forcing the hardware.
Wide access
Both leaves can open when moving large items or creating a broader event entrance.
Daily leaf
One selected leaf handles routine traffic and should align with interior circulation.
Meeting stile
Centre seals, locking and alignment are essential to comfort and security.
Architectural scale
The pair should fit the façade, foyer and available landing rather than size alone.
Weather sealing is concentrated at the centre
The meeting stile is a critical air, water and security detail. Threshold alignment, astragal construction, seals and installation determine how confidently the pair closes.
A covered porch helps exposure but does not eliminate the need for a suitable sill and perimeter water-management plan.

Match the scale to the house
A wide pair can suit larger façades and foyers, but it can overwhelm a modest entrance when sidelights or trim are added without restraint.
Compare a double-door system with a single door and sidelights. One may provide better daily operation while the other prioritizes occasional wide access.
Plan the complete entrance
- Which leaf should operate every day?
- How often is full width actually needed?
- Is the entrance protected from weather?
- Would a single door with sidelights work better?
